INTRODUCTION
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 4
1 INTRODUCTION
For over 300 years, Main Street has been a center for civic activity and commerce. Originally called 'Nonotuck' by
native people who inhabited the lane, Northampton was appropriated and settled by English colonizers in the mid-
1600s. The first store in Northampton opened in 1769 and by the 1800s a concentration of stores along the rutted
Main Street became a shopping destination for local goods and international luxuries. By the 1900s, brick
buildings had replaced wooden ones, giving Main Street much of the look and feel it maintains today.
Today, Main Street is not only a beloved place for locals and tourists to shop and dine but is recognized as a hub
for community activism, arts, culture, and more. The re-envisioning of Main Street through downtown
Northampton is a once in a lifetime generational opportunity with the potential to enhance the city’s social and
economic foundation, ensuring a bright future for this academic, artistic, and countercultural hub.
1.1 PROJECT PURPOSE AND NEED
The existing street design primarily serves to accommodate vehicular traffic, leaving limited space for comfortable
and accessible pedestrian and bicycle facilities. The vehicle-dominated roadway design through Northampton’s
downtown, coupled with a lack of accommodations for people walking and biking through the corridor, creates
unsafe conditions for all roadway users. These conditions are reflected by the inclusion of the entire project area
in the 2008-2017 Highway Safety Improvement Program (HSIP) bicycle and pedestrian crash clusters. These
crash clusters indicate that the study area intersections fall within the top 5% of high crash locations in
Massachusetts.
The reconstruction of Northampton’s Main Street is a natural extension of a decades-long history of proactive
planning. Numerous past and ongoing initiatives have led the City to this point, including initiatives focused
specifically on Main Street and those focused on Northampton as a whole.
The 2021 amendment to the Sustainable Northampton Comprehensive Plan1 lays the groundwork for
Northampton. The plan is built upon a common understanding that emerged through the community
process: that Northampton must "grow and change with a full understanding of this generation's
responsibility to leave behind a community that will not compromise the ability of future generations to
meet their needs." The plan lays out a number of guiding principles, and specifically calls to “make the
city increasingly more walkable, bikeable, and transit-oriented,” a goal that directly influenced the
planning and design process of the Picture Main Street project. As guided by the plan principles and call
for enhanced safety and accessibility for all modes of transportation, the project will better define and
expand sidewalk spaces, install accessible and ADA-compliant curb ramps, provide curb extensions to
shorten crosswalks in key locations, install dedicated and separated bike facilities in both directions
throughout the corridor, and update outdated signal equipment and timing/phasing plans at signalized
intersections.
The Climate Resilience and Regeneration Plan, an element of Sustainable Northampton2 commits
to important benchmarks - such as achieving carbon neutrality by 2050 - and provides a road map to
achieving them. Key recommendations that the Picture Main Street project can support include expanding

stormwater management infrastructure, expanding sustainable transportation options, encouraging
development near downtown, and mitigating heat through open space and trees.
The 2020 ADA Self-Evaluation & Transition Plan and Section 504 Plan3 identifies recommendations
to ensure people with disabilities have equal access in all that the City does. While acknowledging the
extensive resources and work that has been done to improve accessibility throughout Northampton in
recent years, the plan includes recommendations such as providing accessible curb cuts at all
crosswalks, prioritizing snow removal of pedestrian routes in commercial areas, enforcement of parking
rules to ensure accessible routes are not blocked, and expansion of accessible parking spaces.
A Downtown Northampton for Everyone: Residents, Visitors, Merchants, and People at
Risk4 acknowledges the complex relationship between panhandling, people at risk, and Downtown
Northampton. With extensive consideration for the complicated societal context surrounding these issues,
the report offers a range of recommendations for community consideration that could help support at-risk
people while seeking to mitigate the concerns of merchants and others and provide services to residents
who might otherwise be suffering and panhandling (the Community Resilience Hub).
The 2018 Transit Mobility Alternatives Study5 examines ways to improve transit service along the
PVTA B43 route in Northampton, Hadley, and Amherst. With 72% Northampton's ridership activity
concentrated at just three stops - Smith College, the Academy of Music, and the Courthouse - the study
recommends enhanced bus stops with shelters, lighting, passenger information, seating, and bike parking
to support existing and future expanded transit use.
The 2017 Route 9 Safety and Livability Study6 addresses the history of crashes on Main Street and to
help advance the City's other livability goals. Key recommendations from the study include shortening
crosswalks, installing bike lanes, and adjusting traffic signals for more efficient vehicle and pedestrian
traffic flow.
The Walk Bike Northampton Plan, an element of Sustainable Northampton7 identified the
reconstruction of Main Streets with enhanced sidewalks, separated bike lanes, and preservation of a mix
of parallel and angled parking as a top project for improving safe and efficient transportation in the City.
The 2016 Main Street Walk/Bike Assessment, an element of Sustainable Northampton8 provides
recommendations to improve the safety of people walking and biking downtown. Key recommendations
include narrowing Main Street to shorten crossing distances, installing bike lanes, upgrading signal
equipment, and upgrading all curb ramps and sidewalks to meet the Americans with Disabilities Act
(ADA).
The Downtown Northampton Parking Management Study9 examined on and off-street parking
throughout the entire core of Downtown. The study found that parking is considered to be a scarce
resource and that drivers prefer to park on-street, even though on- street spaces on Main Street account
for only 10% of all parking spaces Downtown. The study found that the highest percentage of spaces
used within Downtown at any single time was 72%. The study also found that 23% of vehicles parked on
Main Street at any given time had been there for over 3 hours.
The 2006 Route 9 Railroad Overpass Safety Study10 provides recommendations to improve safety and
awareness of the low-clearance railroad bridge across Main Street.

The 2005 Northampton Streetscape Improvement Plan11 recommends a range of interventions
focused on enhanced beauty and functions of Downtown. Key recommendations include defining travel
lanes within the street, providing bike lanes, new and shorter crosswalks, and the establishment of a civic
plaza in front of City Hall.
1.2 GENERAL/SITE LOCATION
The Main Street corridor in Northampton, Massachusetts is an approximately 0.4-mile segment extending from
West Street/Elm Street at the western limits to Market Street/Hawley Street at the eastern limits (Figure 1). The
corridor is a generally east-west-running principal arterial roadway operating under City of Northampton
jurisdiction, providing pedestrian, freight, transit, and vehicle transportation from surrounding residential streets to
Northampton’s downtown commercial area. The project area, which includes the Main Street corridor and ten
intersections, four of which are signalized, crosses the MassCentral Greenway and New Haven and Northampton
Canal Greenway and is located just east of Smith College and approximately one mile west of Interstate 91.

2 EXISTING CONDITIONS
The following section describes the existing characteristics of the Market Street corridor, the study area
intersections and the surrounding context of the project area.
2.1 EXISTING ROADWAY GEOMETRY
CORRIDORS
Elm Street/Main Street/Bridge Street (Route 9/Route 10)
Massachusetts Route 9 is a principal arterial roadway that is 135 miles long connecting Pittsfield’s city center in
the west to Copley Square in Boston to the east. Massachusetts Route 10 runs from the Connecticut-
Massachusetts border in Southwick to the Massachusetts-New Hampshire border in Northfield. Route 9 runs
along Main Street though the whole project area and Route 10 runs along Main Street between New South Street
and King Street. Main Street is part of the National Highway System (NHS) serving strategic transport facilities
such as rail and truck terminals, airports, and ports. Though Route 9 and Route 10 previously served major east-
west and north-south travel through Massachusetts, I-90 and I-91 primarily serve those movements now. The
study area generally runs in the east-west direction and is approximately 0.4-miles long between West Street/Elm
Street and Market Street/Hawley Street. Land use within the study area primarily consists of commercial and retail
locations, public greenspaces, and some residential uses. Smith College is located at the western end of the
study area and was noted to generate relatively high volumes of foot traffic in downtown Northampton during the
school year.
The street consists of two lanes in each direction between West Street/Elm Street and King Street/Pleasant Street
(Figure 2) before it narrows to one travel lane in each direction from King Street/Pleasant Street to the eastern
terminus of the project area (
Figure 3). The eastbound and westbound travel lanes are generally separated by a double yellow center line with
some median islands scattered throughout the corridor. Turning lanes are provided at all signalized intersections
except Market Street/Hawley Street. The speed limit in the study area is posted at 25 mph. The roadway curb-to-
curb width varies between approximately 54 and 102 feet throughout the corridor with approximately 9- to 28-foot
travel lanes. Pavement, pavement markings, and signage vary from good to poor conditions.

Concrete sidewalks with brick amenity zones are provided on both sides of the corridor, both of which are
generally in good condition. The amenity zone houses street furniture such as benches, streetlights, mailboxes,
waste receptacles, and bicycle racks. Sidewalks, including the amenity zone, vary between 6 feet and 20 feet
along Main Street which sees a high volume of pedestrians visiting downtown Northampton.
Conventional bike lanes are provided west of State Street/New South Street along Main Street. Dedicated space
for people biking along Main Street is not provided east of State Street/New South Street. The Pioneer Valley
Transit Authority (PVTA) and Franklin Regional Transit Authority (FRTA) both operate transit routes along Main
Street with four bus stops within the project area. On-street, metered parking is available throughout the corridor.
Further discussion of bicycle facilities, public transportation, and available parking is included in following

Street consists of a left turn lane and a right-turn lane. The Elm Street eastbound approach consists of a through
lane and a right-turn lane while the Main Street westbound approach consists of an exclusive left-turn lane and a
through lane. Though signage indicates that the eastbound right lane must turn right, field observations saw
vehicles in the right lane use it as a shared through/right-turn lane therefore existing conditions analysis is
conducted as such. Median islands separate the eastbound and westbound approach and receiving lanes.
Marked crosswalks with curb ramps and flashing-hand indications are provided across the West Street
northbound approach. A conventional bike lane is provided along the eastbound and westbound approaches.
Right turns on red are allowed for the eastbound and northbound approaches.
Figure 4. Main Street at West Street/Elm Street and State Street/New South Street
The Main Street at West Street/Elm Street and Main Street at State Street/New South Street intersections operate
with 110 second cycle lengths. At West Street/Elm Street, phasing begins with the eastbound and westbound
approaches running concurrently with the southern crosswalk, the westbound left turn is permitted through this
phase. Then, the West Street northbound left turn and right turn run before the Main Street westbound left turn
and West Street northbound right turn overlap. The signal phasing at Elm Street/West Street can be seen in

Main Street at State Street/New South Street
Main Street at State Street/New South Street is a four leg, actuated-coordinated signalized intersections
approximately 100 feet east of the West Street/Elm Street intersection (Figure 4). The Main Street eastbound
approach consists of a left turn lane, two through lanes, and a right turn lane. A conventional bike lane is provided
between the outermost through lane and the right turn lane and bicycle queue boxes are provided in front of the
eastbound approach. The Main Street westbound approach consists of a dedicated left turn lane, a through lane,
and a right turn lane. The State Street southbound approach consists of a shared left-turn/through lane and a right
turn lane. The northbound approach of New South Street consists of a right turn lane which is channelized and
operates freely despite there being a crosswalk traversing the lane approach.
Crosswalks are provided across the northern, eastern, and southern legs of the intersection in addition to a
diagonal crosswalk from the southwest corner to the northeast corner within the intersection field. A ValleyBike
Share station is located on the southern side of Main Street just east of State Street/New South Street in front of
the Academy of Music and Pulaski Park. Furthermore, eastbound and westbound bus stops are located on the
eastern leg of Main Street in the block between New South Street/State Street and Masonic Street (Figure 6). The
eastbound bus stop is considered a major pulse point in Northampton that sees frequent boarding and alighting,
transfers, and layovers for nine bus routes operated by the PVTA and FRTA.
Figure 6. Pulaski Park Seating (left) Next to Eastbound Bus Stop on South Side of Main Street (right)
At State Street/New South Street, the Main Street eastbound and westbound left turns run concurrently with the
diagonal crosswalk through the middle of the intersection field and a State Street southbound right turn overlap.
Next, the crosswalks traversing State Street and New South Street receive a leading pedestrian interval (LPI)
before running concurrently with the eastbound and westbound through and right turn movements along Main
Street. The eastbound right turn receives a protected right turn arrow if the pedestrian push button for the
southern crosswalk is not actuated. When the crosswalk is activated, the eastbound right turn follows the through

crosswalk is actuated or not. The northbound and southbound movements then operate sequentially with split
phasing while the eastbound right turn and westbound right turn overlap, respectively. The New South Street
northbound right turn and crosswalk across the channelized right turn are not integrated to the signal and are free
running. The eastern crosswalk from the channel island to the north side of Main Street runs concurrently with the
northbound left-turn/through movement. Signal phasing at State Street/New South Street can be seen in Figure 7.
Right turns on red are permitted for all approaches except the Main Street westbound approach.

Main Street at Strong Avenue/Merrick Lane
Main Street at Strong Avenue/Merrick Lane is currently a four-leg, unsignalized intersection approximately 300
feet east of King Street/Pleasant Street (Figure 14). All approaches to the intersection consist of general-purpose
travel lanes with parking available on both sides of the roadways; parallel parking is available along Main Street
and Strong Avenue while angle parking is provided along Merrick Lane. Merrick Lane is a privately-owned
roadway planned for acquisition by the City of Northampton. The City plans to end vehicle access via Merrick
Lane and install bicycle and pedestrian facilities in the future. A crosswalk is provided across Strong Avenue and
the western leg of Main Street.

Rail Trail and the New Haven and Northampton Rail Trail. The sidewalk under the bridge is elevated relative to
the roadway, restricting access to the parallel parking along Main Street. A ValleyBike Share Station is located on
the southern crosswalk next to stairs that provide access to the pedestrian/bicycle bridge and the Northampton
Amtrak station. The bridges are low with 11 feet of clearance space which cannot accommodate large heavy
vehicles such as tractor trailers. Strong Avenue acts as a final escape route for eastbound vehicles approaching
the bridge.

Main Street at Market Street/Hawley Street is a four leg, fully actuated, signalized intersection at the eastern end
of the Main Street project area (Figure 14). The Market Street southbound approach, the Bridge Street westbound
approach, and the Hawley Street northbound approach consist of general-purpose travel lanes. The Main Street
eastbound approach is marked as an approximate 28-foot general purpose travel lane; field observations saw this
approach operating as a shared left-turn/through lane and a short right-turn lane where parallel parking ends. For
existing operations, the eastbound approach is modeled as it operates, with two approach travel lanes. Marked
crosswalks with curb ramps and flashing-hand indications are provided across all approaches. There are no
bicycle facilities provided at the intersection or along the intersection approaches. Right turns on red are restricted
for the eastbound approach. Parking is available on both sides of the western leg of Main Street and on the south
side of the eastern leg of Bridge Street. Hawley Street acts as a final escape route for westbound heavy vehicles
approaching the low-clearance bridge just to the east.
The Main Street at Market Street/Hawley Street cycle length is 101.5 seconds with the signal phasing represented
in Figure 16. Phasing includes concurrent eastbound and westbound approach movements, an exclusive
pedestrian phase, and concurrent northbound and southbound approach movements. The exclusive pedestrian
phase must be actuated by a person walking or biking. Right turns on red are allowed for all approaches except
the Main Street westbound right.

PUBLIC TRANSPORTATION
The Pioneer Valley Transit Authority (PVTA) and Franklin Regional Transit Authority (FRTA) both operate transit
routes along Main Street. The FRTA operates route 31 from Northampton to Greenfield Mondays through Fridays
with about 2-hour headways between State Street and King Street along Main Street. The PVTA operates the
following routes along Main Street:
» 39 (Smith College/Hampshire College/Mount Holyoke College),
» 39E (Smith/Mount Holyoke Express),
» R41 (Northampton/Easthampton/HCC),
» R42 (Northampton/Williamsburg),
» B43 (Northampton/Hadley/Amherst),
» R44 (Florence Heights vis King Street and Bridge Road),
» B48 (Northampton/Holyoke via Route 5), and
» The Nashawanuck Express.
There are four bus stops along Main Street within the project area: eastbound and westbound stops at Masonic
Street (Academy of Music), an eastbound stop at Old South Street, and a westbound stop at Gothic Street
(Courthouse). The eastbound bus stop in front of the Academy of Music is a major transit hub serving all routes to
Northampton. Before the COVID-19 Pandemic beginning in March 2020, over 265,000 trips started or ended at
the Academy of Music in 2019 and over 60,000 bus trips started or ended at the westbound Courthouse stop. The
eastbound Academy of Music stop is a major pulse point acting as a transfer location where buses arrive and
leave around the same time to minimize passenger wait time.
Two of the four bus stops (eastbound Academy of Music stop and westbound Courthouse stop) have bus shelters
and all stops have benches for people who are waiting. Buses sometimes have difficulty pulling up directly to the
curb at stops which requires people to get on and off the bus from the street.
Regional transit providers including Amtrak, Peter Pan, and Greyhound all have a station or bus stop within a five-
minute walk of the project area. These stations and their services provide connections to Eastern Massachusetts,
Vermont, Connecticut, and beyond. In 2019, people took over 22,000 trips starting or ending at Northampton’s
Amtrak Station which can be accessed along Main Street between Strong Avenue and Market Street/Hawley
Street. The Peter Pan bus terminal is located approximately 500 feet south of Main Street at Crafts Avenue’s
intersection with Old South Street. A Greyhound bus stop is located approximately 900 feet south of Main Street
on Conz Street.

EXISTING PARKING
One hundred thirty-six on-street parking spaces are available on Main Street within the project area, including 84
angled parking spaces and 52 parallel parking spaces. Of these existing spaces, 75% (102 spaces) are located
west of King Street/Pleasant Street and 25% (34 spaces) are to the east. Available spaces west of Crafts Avenue
and east of King Street/Pleasant Street primarily consist of parallel spaces and the remaining consisting of head-
end, angled spaces. Five spaces (4%) in the project area are reserved for people with disabilities. Within the
context of the core downtown area (the area within a five-minute walk of Main Street), parking spaces on Main
Street make up 8% of all available parking. Approximately 1,580 parking spaces are available within the
Downtown Northampton core, approximately 543 of which are on-street spaces, including those on Main Street.
There are also over 1,000 additional off-street parking spaces in the downtown area that are privately owned, and
which were not included in this analysis. Some of the primary parking lots available near Main Street are on Old
South Street, Masonic Street, Amory Street along Pleasant Street, and Gothic Street.
A study14 of parking utilization within the downtown area completed in 2015 showed that use of on-street parking
spaces was highest on weekday afternoons when 73% of spaces were occupied. On Saturday, use of on-street
Downtown parking spaces was highest in the evening when 81% of spaces were occupied. Parking on Main
Street is metered with a 2-hour maximum time limit for $1.00 per hour. The 2015 parking study showed that 23%
of people parked on Main Street stay for three or more hours.
BICYCLE NETWORK
People biking can access the MassCentral Rail Trail and the New Haven and Northampton Canal Greenway at
Northampton’s Amtrak Station, Union Station (Figure 17). The MassCentral Rail Trail extends to the north of the
station while the New Haven and Northampton Canal Greenway extends to the south from the station. This well-
established trail network brings people near downtown where there is little to no dedicated space for people on
bikes on Main Street. Conventional bike lanes are provided to the west of State Street/New South Street and
bicycles ride within mixed traffic east of State Street/New South Street. People biking are expected to follow
vehicular traffic signals at the signalized intersections throughout the corridor. At the King Street/Pleasant Street
and Market Street/Hawley Street a mix of behavior is currently observed by bicycles travelling through the
intersections, with some bicyclists waiting to use the vehicular traffic signals and others using the existing
exclusive pedestrian phases depending on when in the signal cycle they arrive at the intersections.

Level of traffic stress (LTS) is a planning tool used to quantify the level of traffic stress that a person bicycling is
likely to perceive while riding on any street or path. The analysis correlates to traffic stress with the physical and
operational characteristics of roadways and crossings. It is based on the premise that a person’s level of stress on
a bicycle decreases as separation from vehicular traffic increases and as traffic volume and speed decrease. The
result of the analysis is a numerical traffic stress ranking for every block, from the lowest stress (LTS 1) to the
highest stress (LTS 4). The analysis is based on the Mineta Transportation Institute’s15 research on low-stress
bicycling and network connectivity. It uses a weakest link principle to score road segments based on vehicular
speed, volume, curbside use, and bicycle facility width/separation, as shown in Figure 18 for bicycles riding in
mixed traffic and Figure 19 for bicycles riding in bike lanes not adjacent parking lanes. The LTS for people biking
along Main Street in existing conditions varies between LTS 2 and LTS 3, as indicated in Table 1.

In 2019, people took 11,643 trips starting and ending at the six ValleyBike stations within the vicinity of the project

MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 27
stations around Main Street start and end at the same station, suggesting that people use ValleyBike for
recreational trips and not for commuting or shopping trips to/from home. Most bike racks on Main Street provide
space for one or two people to park their bikes. Today, there are 45 bike racks on Main Street, the majority of
which are clustered around the Academy of Music or located within Pulaski Park. Between the rainbow crosswalk
at Old South Street and Strong Avenue, there are 10 bike racks available for use (Figure 17).
TRUCK ROUTES
The 11-foot underpass at the pedestrian and bicycle bridge and the railroad bridge requires heavy vehicles to
circumvent the bridge to avoid striking it. The eastern-most bridge is a dead bridge that remains to prevent
damage and subsequent time delays for inspection to the bridge that carries the railroad tracks. Approaching the
bridge from the east, low clearance warnings begin to be provided approximately 1.5 miles west of the bridge in
Hadley. Signage on the approach to Interstate 91 ramps indicate that westbound trucks should turn right to
Damon Road then left onto King Street to access Main Street west of the bridge. The eastbound route similarly
suggests using the King-Damon reroute to avoid the low-clearance bridge. Figure 15 shows where existing
signage is located to reroute traffic away from the bridge.

The Route 9 Railroad Overpass Safety Study conducted in August 2006 says that the alternate route signs are
often white, small, and posted too low, making them difficult to see16. In 2021 there have been four bridge strikes
between January and October and there were three strikes in 2020 and 2019 each. Strikes have caused damage
to the underside of the dead bridge and prolonged delays along Main Street while trucks are being removed. The
study suggested a number of recommendations to improve the existing truck route warning system, including
adding and improving signage as well as installing an active warning system with audible alarms and message
sign when an over-height vehicle triggers a beam across the approach roadways.

3 SAFETY ANALYSIS
Toole Design performed a safety analysis in conjunction with a Road Safety Audit at the project area intersections
and corridors to identify and evaluate possible safety issues that may exist. Crash data was obtained by the
Northampton Police Department and Massachusetts State Police Department to support both efforts. The
following section discusses the crash history patterns and potential roadway features that may contribute to such
patterns.
3.1 SAFETY REVIEW
In January 2016, WalkBoston and MassBike conducted an assessment of pedestrian and bicycle facilities
provided along Main Street between West Street/Elm Street and King Street/Pleasant Street. The assessment,
attached in Appendix A, captured pedestrian and bicycle activity while local colleges were in session and while
those modes saw their highest activity throughout the year. Key findings of the report highlight the walkable
environment of downtown Northampton but identify the wide cross section of Main Street as a barrier between the
shops, restaurants, and other amenities on either side of the street. The undefined lanes and poor sight distances
due to parked cars was attributed to the crashes involving pedestrians and rear ends when drivers unexpectedly
yield to pedestrians in crosswalks. Furthermore, the assessment said the wide, undefined travel lanes, angled
parking, and complex intersections make it difficult to navigate Main Street on a bicycle.
A Road Safety Audit (RSA) was conducted on Thursday, November 21, 2021 and its subsequent report can be
found attached in Appendix A. RSAs are a prerequisite for meeting funding criteria under the Federal Highway
Administration’s (FHWA) Local and Rural Safety Program. Additionally, RSAs are required where all or part of a
proposed project is eligible for the Highway Safety Improvements Program (HSIP). Within the project area, the
intersection of Main Street at King Street/Pleasant Street is part of the 2014-2016 HSIP crash cluster indicating
that it falls within the top 5% of high crash locations in Massachusetts (Figure 22). The entire project corridor also
falls within the 2008-2017 HSIP pedestrian and bicycle crash clusters (Figure 23).

All Safety Issues and Potential Safety Enhancements from the RSA Report are provided on Table 10 through
Table 19 in Chapter 6 of this Functional Design Report. Responses are given to indicate how the proposed safety
issues will be addressed in this project at the two intersections evaluated in the RSA.
3.2 CRASH ANALYSIS AND IDENTIFIED
DEFICIENCIES
Toole Design reviewed crash data available from the Northampton and Massachusetts Police Departments crash
data inventory between the years 2015 and 2017. Crash rates are determined based on the number of crashes
per million vehicles entering the intersection. The average MassDOT District 2 crash rate for signalized
intersections is 0.89 and is 0.62 for unsignalized intersections18. Crash rates, crashes per year, crash severity,
and crash type are summarized for signalized and unsignalized intersections in Table 2 and Table 3, respectively.
A total of 167 crashes occurred throughout the corridor, 82 at signalized intersections, 74 at unsignalized
intersections, and 11 at the bridge underpass between Strong Avenue and Market Street/Hawley Street.

RSA and Pedestrian and Bike Audit are discussed in the following sections. Additionally, the following sections
outline some of the additional deficiencies identified in the RSA that were not attributed to crashes. Collision
diagrams and crash summary tables can be found in the RSA attached in Appendix A.
SIGNALIZED INTERSECTIONS
Main Street’s intersections with King Street/Pleasant Street and Market Street/Hawley Street have crash rates
above MassDOT District 2’s average rate of 0.89 at signalized intersections (Table 2). A majority of collisions at
signalized intersections occurred in 2015 and most, 76%, resulted in property damage only. The most common
crash type was angle collisions (32%), followed by rear-end collisions (29%), and sideswipes in the same
direction (22%).

Main Street at West Street/Elm Street and State Street/New South Street
Among Main Streets intersections with West Street/Elm Street and State Street/New South Street there were 36
crashes in the period analyzed between 2015 and 2017, twelve (33%) of which resulted in non-fatal injuries. The
three most frequently reported crash types include:
» Angle collisions (14 crashes, 39%);
» Rear-end collisions (10 crashes, 28%); and
» Sideswipe (same direction) collisions (6 crashes, 17%).
Angle Collisions
RSA attendees attributed the majority of the angle collisions at both intersections to the wide roadway, offset
geometries, and inconsistent signal equipment and indications that complicate turn movements and confuse
drivers. For example, the Main Street westbound left turn lane onto West Street and the Main Street westbound
right turn lane onto State Street are not provided dedicated signal indications, and instead utilize the indications
provided for the through lanes. Missing indications such as these were noted to be confusing because drivers are
unsure how their movement is controlled within the dedicated turning lanes. Furthermore, while the signal
indications for Main Street, Elm Street, and West street approaches are mounted on mast arms, the indications
for the State Street and New South Street approaches are post mounted on the far side of the intersection. Post
mounted indications are acceptable by MUTCD standards in certain settings; however, mast arm mounted signal
indications provide greater visibility of signal heads which can enhance driver understanding of signal timing and
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 36
phasing as they approach an intersection19. Due to the skewed nature of Main Street at State Street/New South
Street, signal visibility is important in maintaining controlled flow through the intersection.
Sideswipe Collisions
The six sideswipe collisions at the intersections were primarily attributed to poor pavement markings, sign clutter,
and poor advance lane assignment signage. There are no lane assignment designations for the West Street
northbound approach or Main Street approach at State Street, and the Main Street eastbound approach at New
South Street consists of two through lanes but the receiving lanes are wide and unmarked. The pavement
markings and signage are also inconsistent or poorly placed in some locations. For instance, the Elm Street
eastbound approach operates as a dedicated through lane and a shared through/right-turn lane. There are no
advance warnings or pavement markings ahead of the intersection indicating that the outer lane of Elm Street is a
right-turn only lane, but at the intersection a “RIGHT LANE MUST TURN RIGHT” sign faces the eastbound
approach. Though the sign is likely a warning sign for the Main Street eastbound right turn at New South Street,
the placement faces the Elm Street eastbound approach at West Street which may confuse drivers.
Rear-end Collisions
Roadway and traffic control features that are most often attributed to rear-end collisions, as seen on all legs of the
intersection, include inadequate change intervals, speeding to avoid being stopped by a red light, poor signal
visibility, and poor pavement friction. RSA team members noted that many of the crashes at the intersection were
congestion related, specifically the ten rear-end collisions. The relatively lower visibility of the post mounted
indications, as compared to those that are mounted on mast arms, may also be attributed to these rear-end
collisions.
Additional Observed Deficiencies
In addition to the features attributed to collisions above, the RSA noted additional roadway and traffic control
deficiencies that may be confusing or unsafe to drivers, pedestrians, and cyclists through the intersections. First,
the driveway on the south side of Main Street between West Street and New South Street results in unpredictable
turning movements going into and out of the driveway. RSA team members observed Main Street westbound
drivers at West Street making a U-turn and cutting across all eastbound approach travel lanes to access the
driveway. The team also saw drivers turn left out of the driveway, continue in the opposing eastbound approach
travel lanes, and then merge into Main Street westbound traffic within the intersection. Both movements are
unpredictable and unsafe for people driving through Main Street at West Street/Elm Street and State Street/New
South Street.
The RSA noted several deficiencies for people walking and biking through both intersections. At West Street/Elm
Street, team members said that the proximity to Smith College evokes high volumes of jaywalking on Elm Street
between Bedford Terrace and West Street, some using the median island along Elm Street at West Street as a
median island despite no marked crosswalks or curb ramps. The curvature of the Elm Street eastbound approach
also results in the rear passenger side corner of vehicles blocking the bike lane. Blocking the bike lane makes it
more difficult for people biking to establish themselves ahead of vehicles during a red light. When bicycles have
full access, they may ride to the front of the queue and establish themselves ahead of vehicles so they may have
priority through their approach to New South Street where they must weave with motor vehicles. With the
approach blocked, people biking are in mixed with vehicle traffic through the large conflict zone.
At State Street/New South Street, the Main Street eastbound right turn lane is controlled by a green ball when the
southern crosswalk is actuated by a pedestrian and with a green arrow when the crosswalk is not actuated. RSA

MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 37
team members noted that the permitted/protected control is confusing and suggested evaluating the effectiveness
of having the movement be protected or permitted, rather than permitted/protected.
For people crossing along the diagonal crosswalk from the southwest corner to the northeast corner at State
Street/New South Street, the existing marked crosswalk is faded and difficult to see. Considering the nature of the
crosswalk through the middle of the intersection during concurrent left turn phases, it is important that they are
highly visible during the long exposure. The Main Street eastbound and westbound left turns run concurrently with
the pedestrian crossing that calls for 31 seconds when actuated. This time was noted to be too long for those
vehicular movements, and it was suggested that the crosswalk layouts be adjusted and any additional time within
the cycle be reallocated to other movements, specifically the State Street southbound approach that was said to
only allow approximately three vehicles to exit before the end of its phase. RSA team members noted that the
timing and phasing of both signals was “inefficient in meeting the needs of existing traffic demands.” Finally, the
bicycle queue boxes at the Main Street eastbound approach to New South Street are not painted green and their
placement after the short block between West Street and New South Street makes it difficult for people biking to
utilize them.
Main Street at King Street/Pleasant Street
At Main Street at King Street/Pleasant Street there were 27 crashes in the period analyzed between 2015 and
2017, three of which resulted in non-fatal injuries. The three most frequently reported crash types include:
» Sideswipe collisions (10 crashes, 37%);
» Rear-end collisions (9 crashes, 33%); and
» Angle collisions (3 crashes, 11%).
Sideswipe Collisions
RSA attendees attributed seven of the ten sideswipe collisions at the intersection to poor pavement marking
conditions that lead to a misunderstanding among drivers regarding appropriate lane assignment and usage when
approaching and navigating the intersection. Specifically, team members said the Main Street eastbound right
lane was often confused with a parking space, and the four sideswipe collisions on the southwest corner involving
right turning vehicles were likely a result.
Rear-end Collisions
Roadway and traffic control features that are most often attributed to rear-end collisions, as seen on all legs of the
intersection, include inadequate change intervals, speeding to avoid delay, poor signal visibility, and poor
pavement friction. Though none of these features were specifically called out by RSA team members or within
each rear-end collision’s respective crash report, they are the features most commonly associated with rear-end
collisions.
Angle Collisions
Three of the four angle collisions at the intersection involved eastbound left-turning drivers colliding with
westbound through drivers on Main Street. The crash reports reviewed suggested these collisions occurred
during the permitted left-turn phase of the eastbound and westbound movements when the left-turning vehicle
failed to yield to oncoming traffic. For the eastbound left drivers, it may be difficult to judge gaps in the two-
opposing westbound through and through/right travel lanes.
Additional Deficiencies
For people walking at Main Street at King Street/Pleasant Street, audit members noted pedestrians often cross
diagonally from opposite corners of the intersection instead of along marked crosswalks. The pedestrian
clearance time programmed for the exclusive pedestrian phase is inadequate for a diagonal crossing, but RSA
attendees said pedestrians are willing to take the risk to avoid having to wait through the long cycle length for the
next exclusive pedestrian phase.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 38
Furthermore, the RSA notes the narrow sidewalk on the northwest corner of the intersection acts as a pinch point
unable to accommodate the high volumes of pedestrians that queue in that space waiting to cross. The northwest
corner is also the location of a ValleyShare bikeshare station and a bus stop is located just to the west of the
station. The amenities on this corner and the foot traffic attracted to them often creates congested walking
conditions through the narrowed portion of the sidewalk.
Main Street at Market Street/Hawley Street
At Main Street at Market Street/Hawley Street there were 19 crashes in the period analyzed between 2015 and
2017, five of which resulted in non-fatal injuries. The two most frequently reported crash types were angle
collisions (seven crashes, 37%) and rear-end collisions (five crashes, 26%).
Angle Collisions
RSA attendees attributed the seven angle collisions to vehicles phases occurring concurrently with one another
for all movements, though specifically the northbound and southbound movements due to the skewed
approaches and the wide geometry of the Hawley Street northbound approach. Four of the seven angle collisions
were between northbound and southbound vehicles. These drivers are expected to have difficulty finding gaps in
the opposing travel lanes because of the poor sight lines of opposing travel lanes and difficulty in finding gaps in
that traffic as a result. Team members suggested evaluating the feasibility of providing protected left-turn phasing,
narrowing the Hawley Street approach to better align with the Market Street approach, installing lane tracking
pavement markings through the intersection, and relocating Market Street and Hawley Street signal heads to
overhead mast arms to increase safety for all vehicles.
Rear-end Collisions
Team members noted that the post office approximately 250 feet east of the intersection along Bridge Street may
be a source of some of the rear-end collisions on the eastern leg as it attracts a large number of trips and
because some drivers were observed using the post office’s access points to avoid the Market Street/Hawley
Street intersection. The rear-end collisions on the eastern leg may also be due to the parallel parking on the south
side of Bridge Street where vehicles may stop abruptly to pull into a parking space or to let a parked vehicle exit
their space. RSA recommendations do not specifically address the rear-end collisions.
Additional Deficiencies
RSA team members noted that the exclusive pedestrian phase timing was not sufficient for people crossing from
one corner of the intersection to the other despite such observed behavior. It was suggested that either the
exclusive pedestrian phase be extended to allow for the diagonal crossings or that concurrent phasing be
evaluated to reduce delay for all users.
UNSIGNALIZED INTERSECTIONS
Main Street’s intersections with Masonic Street, Old South Street, and Gothic Street have crash rates that exceed
MassDOT’s District 2 average rate of 0.62 for unsignalized intersections (Table 3). A majority of the collisions at
the unsignalized intersections occurred in 2017 and most, 77%, resulted in property damage only. The most
common crash types were angle collisions (31%), single-vehicle collisions (28%), and rear-end collisions (26%).

Main Street at Masonic Street
Of the 15 collisions occurring at Masonic Street, five involved vehicles turning southbound left out of Masonic
Street, three of which collided with pedestrians in the crosswalk across Main Street. RSA attendees noted that the
wide cross section of Main Street makes it difficult to judge gaps in traffic when attempting to turn southbound left
from Masonic Street to eastbound Main Street. Attendees also observed that there is not a stop line or stop sign
for the Masonic Street southbound approach. The lack of signage and markings may amplify the safety risks of
the approach as drivers may not be fully aware that they are required to stop.
Six rear-end collisions occurred along Main Street at Masonic Street, three heading eastbound towards the
crosswalk and three heading westbound towards the crosswalk. RSA team members said the westbound
collisions were likely a result of congestion and spillback from the State Street/New South Street intersection.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 40
The audit team identified that the intersection sees relatively high volumes of pedestrians due to its proximity to
Pulaski Park and the eastbound pulse point bus stop on the south side of Main Street. The crosswalk across Main
Street was said to be highly utilized though there were occurrences of people crossing at unmarked locations
across Main Street. The team also observed that large groups of people waiting for the bus near the crosswalk
make it difficult for drivers to be able to tell when pedestrians are going to cross the crosswalk and that buses
often encroach on the crosswalk when a car is parked in the single space on the south side, west of the
crosswalk.
Main Street at Crafts Avenue
Seven collisions occurred at the intersection, three involving rear-end collisions on the eastbound and westbound
approaches to the crosswalk across Main Street. Rear-end collisions like these at the approach to crosswalks can
often be attributed to poor sight lines of people within the crosswalk that result in a following driver not realizing
the leading vehicle is yielding for a pedestrian waiting to cross. The wide cross section of Main Street and the
parking that inhibits views of the curb ramps may result in poor visibility of pedestrians attempting to cross Main
Street.
RSA attendees said that the wide curb radius of the southeast corner of the intersection and the down sloping
grade of Crafts Avenue away from the intersection results in drivers making high speed turns from Main Street to
Crafts Avenue. This was noted to be concerning due to the poor visibility of the crosswalk across Crafts Avenue
that difficult to see due to street furniture, the curve of the roadway, and the angled parking on the southeast
corner.
Main Street at Old South Street
The primary roadway feature attributed to the collisions at the intersection is the steep uphill grade of Old South
Street as it approaches Main Street. RSA team members said that the steep grade results in drivers being unable
to see the crosswalks across Main Street as well as approaching eastbound and westbound drivers. The steep
grade paired with sight challenges imposed by the angled parking make it difficult for drivers to enter or cross
Main Street traffic.
Main Street at Center Street
RSA team members said that the limited sightlines of the Center Street southbound approach makes it difficult to
enter or cross Main Street traffic, especially with respect to the wide Main Street cross section that becomes more
congested as it approaches the King Street/Pleasant Street intersection. These limited sightlines are apparent at
the crosswalk as well due to the alignment, parking, and oncoming traffic from Main Street.
Main Street at Gothic Street
Similar to Center Street, Gothic Street has difficult sightlines on its approach to Main Street which make it difficult
to enter of cross Main Street traffic. The angled parking at the intersection was attributed to the four of the 13
collisions at the intersection as drivers back out of these spots into oncoming traffic.
Main Street at Strong Avenue
Audit team members observed that Main Street westbound drivers typically make wide turns and do not slow
when turning left onto southbound Strong Avenue.

4 TRAFFIC VOLUMES
Toole Design utilized traffic counts collected in 2019 to evaluate corridor and intersection operations within and
around the project area. The following section outlines the 2019 traffic conditions at all study area intersections
4.1 EXISTING TRAFFIC COUNT DATA
Traffic volume data were collected by automatic traffic recorders (ATRs) and video collection turning movement
counters (TMCs) throughout the study area to analyze vehicular, pedestrian, and bicycle activity. The locations of
the ATR and TMC recordings can be seen in Figure 24.

AUTOMATIC TRAFFIC RECORDER COUNTS
ATR counts were conducted for 24 hours each in 2019 between Strong Avenue and Market Street and between
Masonic Street and Crafts Avenue on:
Tuesday, April 30th,
Wednesday, May 1st, and
Saturday, November 2nd.
The Saturday ATRs at both locations include data for both eastbound and westbound traffic while the weekday
counts do not include eastbound Main Street traffic between Masonic Street and Crafts Avenue. The weekday
eastbound Main Street traffic between Masonic Street and Crafts Avenue were estimated based on 15-minute
directional distributions Table 4 summarizes the existing traffic data collected by the ATRs including daily volume,
design hour volumes, peak-hour percentage (K), directional distribution, vehicle class breakdown, and 85th
percentile speed.

TURNING MOVEMENT COUNTS
Weekday turning movement counts (TMCs), provided in Appendix B, were collected on Wednesday, May 1, 2019
between 7:00 am and 9:00 am and between 3:00 pm and 7:00 pm at all study area intersections. Counts were
redone at Main Street at Market Street/Hawley Street on Wednesday, September 25, 2019 and at Main Street at
Center Street and at Gothic Street on Wednesday, November 6, 2019. Analysis determined that counts did not
require seasonal adjustments. Saturday midday TMCs were collected on November 2, 2019 at all study area
intersections except Main Street at Center Street and Main Street at Gothic Street. Saturday midday counts at
those two intersections were projected based on assumptions considering surrounding intersection volumes and
relative proportions during weekday peak hours.
Peak hours by intersection fall between 7:45 am and 9:00 am in the morning peak hour, 4:15 pm and 6:00 pm in
the evening peak hour, and 11:15 am and 2:00 pm on midday Saturdays. Table 5 outlines the morning and
evening peak hours recorded at each intersection. Analysis determined the network peak hour is from 8:00 am to
9:00 am in the morning peak hour, 4:45 pm to 5:45 pm in the evening peak hour, and 1:00 pm and 2:00 pm on
Saturdays midday. The intersection peak hours and the calculated network peak hour are consistent with ATR
data.

4.2 FUTURE YEAR VEHICLE VOLUMES
Future traffic volumes reflect project, city, regional, and state goals on mode shift and emission reduction,
concepts of reduced demand, and local traffic trends surrounding the project area.
ANNUAL BACKGROUND GROWTH RATE
The MassDOT Traffic and Safety Engineering 25% Design Submission Guidelines suggest use of a background
growth rate to develop future conditions traffic volumes. Guidelines suggest background growth under the
assumption that motor vehicle traffic volumes would continue to grow across the state and that by growing the
volumes, future traffic congestion could be avoided. Motor vehicle traffic growth is inappropriate for this project
considering the project goals and emissions reductions goals of the Pioneer Valley Planning Commission (PVPC)
and City of Northampton. First, the goals of this project include increasing the mode shares of walking, biking, and
transit, and reducing the mode share for vehicular traffic on Main Street. The appropriate basis of design for this
project should therefore be reduced volumes, not increased motor vehicle traffic. Second, the State of
Massachusetts, the PVPC, and the City of Northampton have policies in place that encourage reducing emissions
of greenhouse gases to address the climate crisis. The redesign of our streets to encourage walking, biking, and
transit by making it safe and comfortable is a powerful tool to reduce the greenhouse gas emissions from the
State.
The following sections present the concept of induced and reduced demand, and also presents historic traffic
volumes and trends for Main Street and Northampton.
Induced Demand and Reduced Demand
Conventional engineering practices give priority to avoiding traffic congestion over other important functions of
streets. This practice has left cities with streets that carry more vehicular traffic than necessary and conditions that
are undesirable and unsafe in supporting a multimodal, vibrant downtown, especially for people walking and
biking. If a vehicle trip is made easy and cheap in terms of time and/or money with conveniences such as free
parking and uncongested roads, more people will choose to drive. “Induced traffic” is a term that describes an
increase in motor vehicle traffic volume that follows an increase in capacity or reduction in vehicle travel times. If
the capacity of a street or network is reduced or changes are made that increase travel time and lower speeds,
driving becomes a less appealing travel choice, thus resulting in a reduction of traffic demand, or “traffic
evaporation.” While some trips are still necessary to access offices, schools, medical appointments, grocery
stores, and shops, other discretionary types of trips can be diverted to other modes, routes or times of day, or not
made at all20,21 (Figure 36). It is expected that some reduced demand or traffic evaporation on Main Street will
occur through the implementation and expansion of enhanced pedestrian and bicycle facilities that will welcome
and encourage a greater diversity of users to access Main Street via non-motorized personal vehicles.

Figure 36. Potential for Traffic Evaporation through Mode Share, Diverted Trips, and Change in Travel Time22
Traffic Volume Trends
Throughout the COVID-19 Pandemic there have been vast changes in traffic patterns since March 2020, and
those patterns are continuously evolving. Even outside of these changes brought on by the pandemic, traffic
volumes surrounding Main Street have shown declining trends despite an increase in the population of
Northampton between 2010 (population: 28,549) and 2020 (population: 29,571)23. MassDOT maintains
permanent count stations along Main Street just west of Center Street as well as along Mount Tom Road just
south of Conz Street. On Main Street, traffic counts were recorded every year between 2001 and 2013, then
again in 2015, 2017, 2019, and 2020. The 2020 counts with an ADT of 9,273, 32% lower than 2019 counts, give
an idea of the drastic changes traffic saw within the peak of the COVID crisis. Pre-pandemic counts in 2019 saw
no growth compared to 2017 counts and are about 6% lower than the average of the previous two decades of
available counts. Even without the 2020 outlier, traffic along Main Street has seen a steady decrease over the last
two decades as seen in the negative sloping trendline of Figure 37.

Figure 37. Average Daily Traffic Trends on Main Street West of Center Street over the Last Two Decades
Though 2021 traffic counts are not available along Main Street to get a better understanding of what current and
near-future traffic may look like in downtown Northampton, a permanent count station on Mount Tom Road just
south of Conz Street suggests that traffic counts may see be lower than in pre-pandemic conditions. At this
location, traffic counts were collected every year between 2000 and 2013, and again in 2015, 2018, and 2021
(Figure 38). The 2021 traffic counts conducted in February were 13% lower than the 2018 counts and 11% lower
than the average of all previous years analyzed. The decrease relative to historic traffic counts may reflect a new
“normal” and what conditions a traffic analysis should consider.
Figure 38. Average Daily Traffic Trends on Mount Tom Road South of Conz Street over the Last Two Decades
The basis of design for this project is improved safety and comfort for people walking, riding bicycles, and taking
transit, and increased use of these modes of travel. The review of the historic volume on and near Main Street 14,80018,64915,90016,00113,70013,74614,50014,24313,60013,63013,61013,34713,29215,16213,70913,67110,000

demonstrates that there is no risk that this assumption would underestimate future traffic, as traffic has not grown
for the past 20 years, despite population growth and a vibrant local economy. Applying a growth factor to the
existing traffic volumes would be inconsistent with the project’s fundamental goals and local traffic trends within
Northampton.
PRIVATE AND OTHER SPECIFIC DEVELOPMENT TRIPS
Two developments are proposed within the vicinity of the study area at 79 King Street and at 10 Hawley Street.
Discussion with the City of Northampton also indicated potential redevelopment of St. Mary’s Church on the
corner of Main Street West Street/Elm Street and a residential/mixed-use development in the parcel behind
Northampton City Hall. These developments have not yet been permitted and were not investigated further.
The proposed mixed-use development at 79 King Street will consist of approximately 115,000 square feet of
mixed-use space including 70 senior (55+) residential units and approximately 43,000 feet of retail space. 79 King
Street is approximately 875 feet north of Main Street at King Street/Pleasant Street. The site is to be accessed by
a driveway on King Street which was evaluated to have sufficient sight lines when exiting and entering the
driveway. The residential and retail developments are expected to result in a minor increase ADT along King
Street%. As discussed in the traffic study, the increase in traffic is not expected to significantly impact the
adjacent roadway system, and therefore the impacts of the project were not incorporated in the capacity analysis
of the Picture Main Street project24.
The development at 10 Hawley Street proposes demolition of three buildings associated with the St. John Cantius
Church located on the corner of Hawley Street and Phillips Place and development of six condominium blocks on
the same corner. Additionally, a commercial space (400 square feet) is proposed in one of the condominium
buildings and access will be provided via two driveways, one on Hawley Street and one on Phillips Place. The
traffic impact study of the site expects five or fewer vehicles to be added to the Hawley Street northbound left and
right turn and Main Street eastbound right turn in the peak hours at the intersection of Main Street at Market
Street/Hawley Street. The minor increase in traffic of these maneuvers is not expected to significantly impact the
intersection, as shown in the study, and therefore those trips were not incorporated in the capacity analysis of the
Picture Main Street project.

CHAPTER 5:
MUTCD SIGNAL WARRANTS
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 60
5 MUTCD SIGNAL WARRANTS
A signal warrant analysis was conducted for all intersections in the project area. Traffic signal warrant analysis
follows the methodology of Chapter 4C, Traffic Control Signal Need Studies from the 2009 Manual on Uniform
Traffic Control Devices (MUTCD). The 2009 MUTCD recommends that one or more traffic signal warrants are
satisfied to justify the installation of a traffic signal, though installation is not required based on satisfaction. Per
MassDOT guidelines, the Eight-Hour Vehicular Volume warrant must be satisfied to justify signal installation. The
following outlines the intent of each signal warrant:
» Warrant 1, Eight-Hour Vehicular Volume – Satisfaction of this warrant indicates that a high volume of
intersecting traffic from the major street approaches likely causes excessive delay or conflict to the
minor street approaches.
» Warrant 2, Four-Hour Vehicular Volumes – The warrant is satisfied when large approach volumes
from both the major and minor roadways create excessive conflict at their intersection.
» Warrant 3, Peak Hour – The is satisfied where there is excessive delay or conflict between high
approach volumes from minor and major roadway approaches, but it may only be applied in “unusual
cases, such as office complexes, manufacturing plants, industrial complexes, or high-occupancy
vehicle facilities that attract or discharge large numbers of vehicles over a short time.”25
» Warrant 4, Pedestrian Volume – The warrant is applicable where pedestrians experience excessive
delay attempting to cross the major street.
» Warrant 5, School Crossing – The warrant is evaluated when the presence of crossing school
children is the major factor for consideration of a signal.
» Warrant 6, Coordinated Signal System – The warrant is applicable where signalizing a currently
unsignalized intersection within a coordinated system will help to maintain proper platooning of
vehicles.
» Warrant 7, Crash Experience – The warrant is evaluated when installing a traffic signal may reduce
the severity and frequency of recorded crashes.
» Warrant 8, Roadway Network – Evaluation of this warrant is typically provoked by the need to
concentrate and organize traffic patterns within a network.
» Warrant 9, Intersection Near a Grade Crossing – This warrant is evaluated when all other warrants
are not applicable but the proximity to a grade crossing is the primary reason for consideration.
Of the nine signal warrants, the Four-Hour Vehicular Volume warrant and the Pedestrian Volume warrant are
applicable at nearly all study area intersections and were evaluated, as indicated in Table 6. The only location the
Four-Hour Vehicular Volume warrant is not applicable at is Main Street at Crafts Avenue because Crafts Avenue
is one-way southbound away from Main Street. The Pedestrian Volume warrant is still applicable at this location
because there is a crosswalk across the western leg of Main Street. The Roadway Network warrant is applicable
at West Street/Elm Street, State Street/New South Street, and King Street/Pleasant Street because those
intersecting roadways are classified as principal or minor arterial roadways. Though the Eight-Hour Vehicular
Volume warrant is not applicable throughout the corridor because traffic data are not available for eight hours,
ATRs were used to project midday traffic counts, between 9:00 am and 3:00 pm. Similar to the Four-Hour
Vehicular Volume warrant, the Eight-Hour Vehicular Volume warrant is not applicable with the projected data at
Crafts Avenue because the Crafts Avenue is one-way away from Main Street.
The Peak Hour warrant is not applicable at any of the study area intersections because none are located near
“unusual cases” as defined above. There are no schools located within the vicinity of the corridor, making the

MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 61
School Crossing warrant not applicable. The Coordinated System warrant is not applicable because signalizing
any of the existing unsignalized intersections would result in signalized intersection spacing less than 1,000 feet.
The Crash Experience warrant is not applicable at any of the intersections because the primary reason for
evaluating the warrants at the unsignalized intersections is not because of the crash histories. The Roadway
Network warrant is not applicable at Masonic Street, Crafts Avenue, Old South Street, Center Avenue, Gothic
Street, or Strong Avenue because each of those intersecting roadways is classified as a collector or local
roadway. Finally, there are no at-grade crossings near any of the study area intersections, therefore Warrant 9 is
not applicable.

5.1 TRAFFIC DATA
The traffic count data used for the signal warrants were collected on May 1, 2019 between 7:00 am and 9:00 am
and between 3:00 pm and 7:00 pm at all study area intersections. Since only six hours of traffic data are available
for evaluation, traffic counts between 9:00 am and 2:00 pm were estimated for all study area intersections with
available ATRs. Traffic count data is included in Appendix B and discussed further in Chapter 4.
5.2 WARRANT ANALYSIS
A summary of the traffic signal warrant analysis at each of the study area intersections is provided in Table 7 and

The Pedestrian Volume warrant is not satisfied at any intersection during the weekday counts available and the
Roadway Network warrant is satisfied at all signalized intersections evaluated. The Eight-Hour Vehicular Volume
warrant and the Four-Hour Vehicular volume warrant is satisfied at the signalized intersections of West Street/Elm
Street, State Street/New South Street, and King Street/Pleasant Street and the unsignalized intersections of Old
South Street and Strong Avenue. Though satisfaction of these warrants may warrant signal installation based on
traffic volumes, installing a traffic signal at these locations would result in signal spacing less than 1,000 feet
which may result in disrupted traffic flow along the corridor. As such, signal installation at Old South Street and
Strong Avenue is not proposed in this project.

6 PROPOSED DESIGN
ALTERNATIVES
6.1 PUBLIC ENGAGEMENT UP TO DESIGN
ALTERNATIVE DEVELOPMENT
The project team has consistently sought the feedback and support of residents, business owners, visitors, and
other stakeholders to strengthen the responsiveness and relevance of the Main Street design to current and
future users. The engagement process specifically informed the development of conceptual alternatives and
selection of a preferred alternative that has evolved into the plan presented in this Functional Design Report. The
following is a summary of the public engagement process from the beginning and leading up to the selection of a
preferred alternative. The specifics of the preferred alternative components are discussed in 6.5 Preferred Design
Alternative, where the public process leading to the evolution of that alternative is also summarized.
Public and stakeholder engagement started in January 2020. From winter to fall 2020, at least ten meetings were
conducted with stakeholder groups and City committees, including the:
» Project Advisory Group,
» Business Stakeholder Group,
» Joint Parking and Bike/Ped Committee,
» Transportation & Parking Commission,
» Bicycle and Pedestrian Subcommittee,
» Planning Board,
» Downtown Northampton Association, and
» Chamber of Commerce/Economic Development Committee.
Meetings were focused on topics relevant to each group, with the Project Advisory Group providing general
oversight of project priorities and processes. The Project Advisory Group was made up of business owners,
business association members, City committee and commission members, City staff, and Toole Design staff.
Virtual community meetings were held throughout the project via Zoom. Each meeting was attended by 150-180
people. The first open community meeting was held January 13, 2020 and provided an overview of previous plans
and analyses, an existing vision for Main Street that originated with the 2017 Walk Bike Northampton Concept
Design, and the project goals to:
» Provide safety and access for all,
» Promote a vibrant and attractive downtown, and
» Create a functional, enduring, and sustainable streetscape.
Plans for a tactical demonstration project to be installed later in the year were also summarized, and open
discussion was held. Major themes the public asked about were:
» Accessibility related to ramps, sufficient ADA parking, and shuttle service,
» A desire for more data for both traffic on what potential enhancements provide the most benefit,
» Amenities people would like to see, and
» Removal of parking.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 65
The first community survey was released at this time and closed in March 2020. The survey sought feedback on
goals, with some community themes rising to the forefront under each goal. Themes evolved into the criteria to be
evaluated as part of the design alternatives summarized in the following section (6.2 Geometric Design
Alternatives). Also discussed were specific design elements people identified that they would like to see
incorporated into Main Street. Of twenty-three elements voted on, the top-ranked elements were:
» Café with wider sidewalk,
» Protected bike lane,
» High-visibility crosswalk,
» Art crosswalk, and
» Street closure.
Due to COVID-19, the original vision for the tactical demonstration project was to provide relief for restaurant
owners through the addition of space for outdoor dining in existing parking areas along Main Street. This project
was supported by a MassDOT Shared Streets and Spaces grant. It included painted sidewalk extensions,
protected bike lanes, single travel lanes, and parallel parking in place of some angled parking. The project was
installed August 20-22, 2020, and feedback was received via survey, a meeting with business groups, comments
on social media, and petitions. While many members of the public responded positively to the installation,
negative reactions from business owners drove the installation to be removed September 14-15, 2020.
Takeaways from the public survey on this demonstration project were presented in the next community meeting
held in November 2020.
In the November 2020 community meeting, a summary was provided of the first survey and the work completed
to date, including the demonstration project and lessons learned. Two early conceptual ideas were presented as
well, with one focused on maximizing sidewalk space and the other incorporating a center running median with
trees. Breakout groups were then hosted to discuss these concepts, and once all meeting attendees returned to
the wider group, breakout leaders presented the top items discussed in their sessions. The public was also asked
through a Zoom poll how they would like to be engaged going forward and this informed the public process in
2021.
Partly as a response to the feedback received in the November 2020 public meeting, the project team developed
a story map website called Picture Main Street over winter 2020/2021. It is a living site that is kept updated with
the latest project news, timeline, and public process. Previous plans, studies, and data are linked to the site with
summary information. The reaction to this site has been positive as it communicates how design decisions have
been made from the start and lets the public know how their participation and feedback has informed the direction
of the design.
The website was rolled out in the third public meeting, held February 23, 2021, and several comment forms
included throughout the site. These covered such themes as what people see when they picture Main Street in
2030 and beyond, how the pandemic has affected their travel, where they would like to see bike parking, among
others.
The design alternatives developed, as summarized under the following section, 6.2 Geometric Design
Alternatives, were presented in detail at the fourth public meeting on April 14, 2021. Alternative cross sections
were described along with primary benefits and trade-offs. Evaluation criteria were discussed generally and then
applied across each alternative, with points given for how well the different aspects of each alternative met the
criteria. The full comparative evaluation for each alternative as informed by community feedback and preferences
is summarized in the following section, 6.4 Design Assessment.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 66
6.2 GEOMETRIC DESIGN ALTERNATIVES
Based on feedback from public meetings, surveys, and conversations held throughout 2020, several high-level
alternatives were developed for consideration on Main Street. These alternatives represent the spectrum of
opinions that were shared with the city and Northampton’s overall goals for safety, accessibility, vibrancy, and
sustainability. From the preservation of parking to shorter crosswalks to adding bike lanes to reducing traffic
congestion, a wide range of priorities were expressed by Northampton stakeholders. A discussion of those
alternatives and their benefits and tradeoffs are provided in the following sections.
ALTERNATIVE 1A: FOUR VEHICLE TRAVEL LANES WITH
ANGLED PARKING AND SEPARATED BIKE LANES
Alternative 1A was developed in direct response to suggestions by community members at public meetings held
in 2020. Between Masonic Street and Gothic Street, this alternative includes four marked vehicle travel lanes,
angled parking, separated bike lanes, and sidewalks ranging from 4.5 to 25 feet in width (Figure 39). Curb
extensions are used to narrow most crossings to an average of 53 feet. At the signalized intersections at New
South Street/State Street and King Street/Pleasant Street, additional vehicle travel lanes are added to manage
turning movements. As a result of the additional space required by the turn lanes at these intersections, sidewalks
are narrowed, on-street parking is removed, and people biking are required to merge into motor vehicle travel
lanes.
Figure 39. Alternative 1A Proposed Cross Section
Benefits
» Four vehicle travel lanes are formalized and clarified. A wider outside lane is included to help with
maneuvering in and out of angled parking spaces.
» Curb extensions shorten some crossings and ensure crossing pedestrians are visible to drivers. The
average crosswalk length in Alternative 1 is 53 feet.
» 3 commercial loading zones/flex zones are provided curbside to improve visibility for drivers on Main
Street, improve safety for delivery workers, and provide space for flexible curbside uses such as pick-
up/drop-off or 5-minute parking during times of day when commercial loading activities are not active.

TOOLE DESIGN | 67
» Sidewalks are expanded at select locations, including in front of City Hall, near First Churches, and
near Thornes.
» Separated bike lanes are provided between Masonic Street and King/Pleasant Street.
» Some new trees or green infrastructure may be incorporated at curb extensions.
» Enhanced Courthouse bus stop with amenity space for people waiting to take the bus.
» Potential space for approximately 16 new trees provided.
Trade-offs
» Existing sidewalks are narrowed on almost all blocks. The sidewalk must be decreased to less than 5
feet in multiple places in order to fit all desired elements.
» Multiple threat scenarios are present at unsignalized intersections for crossing pedestrians where two
or more vehicular travel lanes per direction must be crossed. Multiple threat scenarios occur when a
driver, Car A, in one travel lane yields for a person walking or biking in the crosswalk, and a driver in an
adjacent travel lane, Car B, does not yield because their sight line of the pedestrian/bicyclists is
impeded by the yielding vehicle, as illustrated in Figure 40. In the multiple threat scenario, either the
pedestrian/bicyclist or the unyielding vehicle, Car B, must quickly stop to avoid a collision. For a
bicyclist, the likelihood of conflict is potentially higher than for pedestrians due to the relatively faster
speeds that bicyclists travel at and the associated inability to stop suddenly.
» This design makes many existing and potential future outdoor dining spaces impossible to meet ADA
requirements.
» Approximately 20 existing trees are removed.
» Outside of curb extensions, there is little to no space for furnishings, plantings, or green infrastructure
features.
» Widened intersections eliminate space for separated bike lanes between Masonic Street and State
Street, and King Street/Pleasant Street and Strong Street.
» At unsignalized intersections where left turn lanes cannot be accommodated due to the wider cross
section, left turns become more dangerous for all modes. Without dedicated turn lanes, left-turning
motorists must find gaps in two lanes of oncoming traffic, a bike crossing, and crosswalk under
pressure from traffic behind them. This also creates the potential for a line of vehicles to form behind
people waiting to turn left, even if they intend to continue straight, which increases the likelihood of
rear-end crashes.
» An estimated 21% of existing parking spaces are lost to accommodate additional vehicle turn lanes at
intersections, four continuous travel lanes, improved crosswalk visibility, and bike lanes.

ALTERNATIVE 1B: FOUR VEHICLE TRAVEL LANES WITH
ANGLED PARKING
Alternative 1B differs from 1A by eliminating the separated bike lane in favor of wider sidewalks (Figure 41). All
other design elements remain the same as Alternative 1A. The concept was developed in recognition of the loss
of existing trees in Alternative 1A and the desire for additional sidewalk space. However, Alternative 1B does not
include any dedicated space for people biking. Sidewalks in Alternative 1B range from 4.5 to 33 feet in width.
Painted shared lane bicycle markings are provided in the outside travel lane, which are not shown to provide any
tangible safety or comfort benefit to people biking.
Figure 41. Alternative 1B Proposed Cross Section
Benefits
» Four vehicle travel lanes are formalized and clarified. A wider outside lane is included to help with
maneuvering in and out of angled parking spaces.
» Curb extensions shorten some crossings and ensure crossing pedestrians are visible to drivers.
» Most sidewalks are expanded between Cracker Barrel Alley and Gothic Street. In some areas the
expansion is significant, providing space for wider pedestrian travel ways, new trees, and green
infrastructure, public art, outdoor dining and commerce, snow storage, and more generous buffers
between pedestrians and motor vehicles.
» Approximately 3 commercial loading zones/flex zones are provided curbside to improve visibility for
drivers on Main Street, improve safety for delivery workers, and provide space for flexible curbside
uses such as pick-up/drop-off or 5-minute parking during times of day when commercial loading
activities are not active.
» The bus stop just west of King Street/Pleasant Street is expanded with amenity space for people
waiting to take the bus.
» All existing trees are preserved except for one, and space for an estimated 25 new trees is provided.
Trade-offs
» The sidewalk must be decreased to less than 5 feet in multiple places in order to fit all desired
elements.
» Multiple threat scenarios are present at unsignalized intersections for crossing pedestrians where two
or more vehicular travel lanes per direction must be crossed.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 69
» Left turns become more dangerous for all modes at minor intersections. Without dedicated turn lanes,
left-turning motorists must find gaps in two lanes of oncoming traffic, a bike crossing, and crosswalk
under pressure from through traffic behind them.
» An estimated 21% of existing parking is lost to accommodate additional vehicle turn lanes at
intersections, four continuous travel lanes, expanded sidewalks, and to improve visibility at crosswalks.
» No dedicated and separated bicycle facilities are provided, leaving safety concerns unaddressed. Note
that it is unlikely that MassDOT would approve this option to receive federal aid assistance for
construction.
ALTERNATIVE 2: FOUR VEHICLE TRAVEL LANES WITH
PARALLEL PARKING AND SEPARATED BIKE LANES
This alternative was developed as a compromise between two commonly-voiced priorities: providing four vehicle
travel lanes and providing space for expanded sidewalks and separated bike lanes (Figure 42). Between Masonic
Street and Gothic Street, this alternative includes four marked vehicle travel lanes, parallel parking, separated
bike lanes, and sidewalks ranging from 4.5 feet to 35 feet in width. Curb extensions are used to narrow most
crossings to an average of 53 feet.
The additional sidewalk width along much of the street provides significant space for expanded public space,
outdoor dining and commerce, lush greenery and trees, snow storage, and green infrastructure. At the signalized
intersections at New South Street/State Street and King Street/Pleasant Street, additional vehicle travel lanes are
added to manage turning movements. As a result of the additional space required by the turn lanes at these
intersections, sidewalks are narrowed, on-street parking is removed, and bike lanes are discontinued.
Under this alternative, parking layout would be consistent the entire length of Main Street, building on what
already works west of City Hall and east of King/Pleasant Street.
Figure 42. Alternative 2 Proposed Cross Section
Benefits
» Four vehicle travel lanes are formalized and clarified.

» Sidewalks are expanded between Cracker Barrel Alley and Gothic Street. In some areas the expansion
is significant, providing space for wider pedestrian walkways, new trees, and green infrastructure,

» Curb extensions shorten most crossings and ensure crossing pedestrians are visible to drivers. The
average crosswalk length in Alternative 2 is 53 feet.
» Approximately 3 commercial loading zones/flex zones are provided curbside to improve visibility for
drivers on Main Street, improve safety for delivery workers, and provide space for flexible curbside
uses such as pick-up/drop-off or 5-minute parking during times of day when commercial loading
activities are not active.
» Separated bike lanes are provided between Masonic Street and King/Pleasant Street.
» Space for an estimated 16 new trees provided.
Trade-offs
» The sidewalk must be decreased to less than 5 feet in multiple places in order to fit all desired
elements.
» Multiple threat scenarios are present at unsignalized intersections for crossing pedestrians where two
or more vehicular travel lanes per direction must be crossed.
» Approximately 14 existing trees must be removed.
» Left turns become more dangerous at minor, unsignalized intersections for all modes. Without
dedicated turn lanes, left-turning motorists must find gaps in two lanes of oncoming traffic, a bike
crossing, and crosswalk under pressure from through traffic behind them.
» With the conversion to parallel parking, an estimated 37% of existing parking is lost to accommodate
additional vehicle turn lanes at intersections, four continuous travel lanes, expanded sidewalks,
improved visibility at crosswalks, and bike lanes.
ALTERNATIVE 3: THREE VEHICLE TRAVEL LANES WITH
ANGLED AND PARALLEL PARKING AND SEPARATED BIKE
LANES
This alternative was developed as a compromise between two commonly-voiced priorities: preserving angled
parking and providing space for expanded sidewalks and separated bike lanes. Between Masonic Street and
Gothic Street, this alternative includes three marked vehicle travel lanes including a dedicated left-turn lane,
angled parking, separated, sidewalk-level bike lanes, and sidewalks ranging from 6 feet to 35 feet in width (Figure
43). Curb extensions are used to narrow most crossings to an average of 38 feet.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 71
Figure 43. Alternative 3 Proposed Cross Section
Based on FHWA case studies, roadways with 25,000 vehicles per day or less can typically achieve safety,
sustainability, and economic vitality goals of a community and project with three travel lanes26. As noted in
Chapter 4, Main Street carries an ADT of approximately 14,000 vehicles per day. The safety benefits of a three-
lane street compared to a four-lane street are also well documented. Studies have shown reductions in overall
crashes by 19% to 47% on streets that have been converted from four lanes to three. When compared to four
lane streets, three lane streets provide safety benefits to all users by significantly reducing the number of common
crash points along the corridor as well as at intersections (Figure 44). Giving people who want to turn left their
own lane minimizes the potential for rear-end crashes and also reduces the likelihood of sideswipe crashes that
occur when people change lanes. It also minimizes the feeling of pressure from behind for making a left turn,
reducing the likelihood of a motorist making a left turn with an insufficient gap in oncoming traffic. For pedestrians,
the multiple threat scenario is eliminated as three lane streets offer significant visibility improvements at
crosswalks and reduce the number of lanes that a person has to cross. A center turn lane also provides a clear
path for emergency vehicles, where four lane streets can be difficult for emergency vehicles to navigate (Figure
45).

intersections at New South Street/State Street and King Street/Pleasant Street, additional vehicle travel lanes are
added to manage turning movements while maintaining on-street parking and separated bike lanes.
Benefits
» Three vehicle travel lanes, including dedicated left-turn lanes, are formalized, and clarified. A wider
outside lane is included to help with maneuvering in and out of angled parking spaces.
» Center turn lanes make left turns safer and less stressful for all modes, while also providing efficiency
benefits to traffic flow by reducing merging traffic
» Sidewalks are expanded between Cracker Barrel Alley and Gothic Street. In some areas the expansion
is significant, providing space for wider pedestrian walkways, new trees, and green infrastructure,
public art, outdoor dining and commerce, snow storage, and more generous buffers between all users.
» Curb extensions shorten all crossings and ensure crossing pedestrians are visible to drivers. The
average crosswalk length in Alternative 3 is 38 feet.
» Multiple threat scenarios are mostly eliminated for people walking and biking at marked, unsignalized
crossing locations.
» At major intersections with traffic signals, smaller intersection footprints allow for more efficient traffic
signal phasing and reduce wait time for people walking and biking.
» Continuous, separated, sidewalk-level bike lanes are provided throughout the project area, with a
section of street-level separated bike lanes between Strong Ave and Market/Hawley.
» Approximately 3 commercial loading zones/flex zones are provided curbside to improve visibility for
drivers on Main Street, improve safety for delivery workers, and provide space for flexible curbside
uses such as pick-up/drop-off or 5-minute parking during times of day when commercial loading
activities are not active.
» All existing trees are preserved except for one, and space for an estimated 25 new trees is provided.
» Additional flex space provides space for snow storage and emergency vehicle operations.
Trade-offs
» An estimated 29% of parking is removed to provide visibility at crosswalks, public space, bike lanes,
and additional vehicle turn lanes at intersections.
» Delay for people driving would increase modestly as they approach Downtown along State Street or
West Street. Additional changes to the State Street/Main Street intersection could be considered to
mitigate increased delay for drivers at this intersection.
ROUNDABOUT ANALYSIS
The MassDOT Guidelines for the Planning and Design of Roundabouts was used during the initial stages of the
project to do a high-level analysis of the feasibility of installing roundabouts at the intersections along Main Street.
Roundabouts were not considered further at unsignalized intersections due to the relatively heavy flow of through
traffic along Main Street relative to the light minor street traffic, the proximity to signalized intersections that may
result in spillback, the heavy concentration of pedestrian activity in the corridor, and the unfavorable geometry at
some of the unsignalized intersections29.
At Main Street at West Street/Elm Street and State Street/New South Street the limited right-of-way at State
Street/New South Street, approximately 90 feet at the narrowest points, does not support spatial needs of a
single-lane or multilane roundabout that calls for 105- to 150-foot inscribed circle diameters, respectively (the
29 MassDOT Guidelines for the Planning and Design of Roundabouts, Section 2.2 Context, Table 2-1: Site-Specific Conditions that Influence

diameter measured from the outer edge of the circulating lanes)30. The limited right-of-way at King Street/Pleasant
Street and at Market Street/Hawley Street are also insufficient to support the spatial needs of single or multi-lane
roundabouts, especially with respect to the need for pedestrian and bicycle facilities that would circulate any
roundabout.
6.3 PUBLIC ENGAGEMENT FROM ALTERNATIVE
DEVELOPMENT TO DESIGN ASSESSMENT
The design alternatives summarized under 6.2 Geometric Design Alternatives were presented in detail at the
fourth public meeting on April 14, 2021. Alternative cross sections were described along with primary benefits and
trade-offs. Evaluation criteria were discussed generally and then applied across each alternative, with points
given for how well the different aspects of each alternative met the criteria. A graphic example of this is shown in
Figure 46, and the evaluation criteria methodology applied to each alternative is summarized in Table 8.
Figure 46. Alternative 2 Benefits, trade-offs, and evaluation
A question-and-answer session was held as part of the April 2020 meeting to seek feedback on the alternatives.
An alternatives-focused survey was also released that asked people to rank the importance of the listed criteria
and to rank the alternatives comparatively, expressing which was most and least preferred. The results of the
survey were presented at a fifth public meeting held on June 24, 2021. Over 1,200 completed responses were
received, and the results showed that:
» Most people feel most of the criteria are important to achieve for Main Street.
» Space for trees and green infrastructure was selected as the highest importance of all design criteria by
80% of respondents.

» Most respondents (70%) selected Alternative 3 as their most preferred.
» Alternative 2 was the middle ground alternative, and it was both least liked and least disliked.
» Alternative 1B was the most disliked, with 40% of people selecting it as their least preferred.
6.4 DESIGN ASSESSMENT
Each of the alternatives were measured against a set of evaluation criteria that align with the project goals, as
seen in Table 8. The ratings shown for each alternative are based on the methodology in Table 9. Alternative 3
was selected as the preferred design and was ultimately chosen to advance due to highest satisfaction of
evaluation criteria compared to the other alternatives and continued engagement with the public, local and state
stakeholders, and City staff. The principles and evolution of the alternative is discussed under 6.5 Preferred

6.5 PREFERRED DESIGN ALTERNATIVE
Alternative 3 was selected as the preferred alternative based on the evaluation criteria, community input, and
review of over 1,200 survey responses. Alternative 3 generally includes three vehicle travel lanes, expanded
sidewalks, separated bike lanes, and a mix of parallel and angled parking. However, since the alternative was
originally presented in the April 2021 public meeting, it has undergone an evolution as a response to continuing
City and public feedback.
EVOLUTION OF THE PREFERRED ALTERNATIVE
When Alternative 3 was originally presented (Figure 47), angled parking was designated in the central portion of
Main Street where space allowed, from Crafts Avenue to Gothic Street. Parallel parking was necessary in the
narrower portions of the roadway to the west and east of the central section. The full cross section of the street
was discussed in a sixth public meeting held June 24, 2021. The function and dimensional requirements of each
zone were described in detail from the center of the roadway up to building faces at the back of sidewalk.
Figure 47. Alternative 3 cross section as discussed in detail with the public.
Sidewalk zones and elements that support tree health were also described in detail. During the discussion portion
of the meeting, several people stated that they did not think Alternative 3 went far enough in expanding the
sidewalk and space for trees, public amenities, and outdoor dining. Many people simultaneously stated that they
supported converting angled parking to parallel to create space for an expanded sidewalk.
The meeting happened during the summer just before an updated assessment was completed by the City Tree
Warden for all the trees along Main Street. In comparison to a 2016 assessment, which found 63% of trees in
good condition and very few in poor condition, in 2021 the Tree Warden found that only 34% of trees were in
good condition, and 37% were in poor health. The Urban Forestry Commission had called for the updated
assessment and had also provided written notice that the Commission did not feel that Alternative 3 best created
a continuous tree canopy, as the original scheme preserving the majority of trees in locations without an
established spacing and with many gaps.
The tree assessment and public feedback from the June 2021 meeting drove conversations with the City as to
how to advance the design. Toole Design ultimately developed a concept that converted angled parking over to
parallel on the north side of Main Street after finding that the north side was more in need of expanded sidewalk
space than the south.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 79
This updated concept was presented to the
public in the second of three meetings that
addressed different portions of the street.
Public meetings with the preferred
Alternative 3 design as the focal point of
discussion were as follows:
» September 21 meeting on section east
of King/Pleasant intersection,
» September 30 meeting on the central
section from Masonic Street to
King/Pleasant Streets, and
» October 19 meeting on the west end
from West/Elm Streets to Masonic Street/
The meetings were interactive, where a
portion of the street was presented in plan,
and then attendees could see their input
attached directly to the plan. This was
supported by the Miro online platform.
During the second meeting, cross sections
were used to illustrate the benefit of
converting angled parking to parallel on the
north side, as seen in Figure 48. Nine feet
from parking and three feet from the travel
lane could be devoted to sidewalk space,
therefore supporting a wider treeway, wider
walking space, and more room for outdoor
dining, art, seating, and other amenities.
While sidewalk widths vary, the south side
of Main Street (Figure 49) already had a
large segment, from Crafts Avenue to
Center Street, with expanded sidewalk
space with angled parking adjacent. Thus,
converting angled parking to parallel was
not considered necessary.
The additional parking reductions due to
the north side conversion were specified in
the September 30 meeting. Many people
responded positively to the change and
even pushed for conversion to parallel on
the south side. However, concerns were
raised, particularly by those with
disabilities, as to the increased challenge
of parallel parking versus angled. The
scheme presented with the 25%
Figure 48. Effect of converting angled parking to parallel on the north
side of Main Street
Figure 49 The south side has wider sections of sidewalk even with
angled parking.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 80
submission maintains angled parking on the south side and includes design changes made to designate ADA
angled parking.
SEPARATED BIKE LANES
As shown in the Alternative 3 cross sections and discussed in Table 10, proposed bike lanes are separated from
the roadway and parking via a 3-4 foot wide buffer. Bike lane width is typically 5.5 feet, though narrowed to 4 feet
wide as necessary due to constrained sidewalk widths and bus stops. The bike lanes are generally raised to
sidewalk level. Some beveled curb is incorporated into the design to make bike lane grades more comfortable for
people on more than two wheels. Beveled curb is also helpful at intersections and bus stops to guide the visually
impaired toward pedestrian crossings and to accommodate curb ramp grading and placement of detectable
warnings on either side of the bike lanes in the next stage of design.
DESIGN FOR TREES
All input received from the City and public to date has prioritized trees and the methods to best support their
health and growth. Due to the assessment mentioned above, most existing trees on Main Street are planned to
be removed. Their current positioning is not optimal under the redesign, and the trees are planted in constrained
pits with poor soils. Removal allows newly planted trees to be spaced at 35 feet on center, a spacing that allows
adequate air and sun to reach leaves. Large tree openings are planned to be surfaced with porous rubber
flexipave with wide openings directly at the base of trees to prevent smothering young trees. Tree root systems
are expected to pull up the flexipave over time.
The design seeks to provide adequate rooting space underneath the sidewalk, aiming for 1,000 cubic feet per
tree. This will partly be achieved by planting trees in a treeway with shared soils. Additionally, structural soil will be
incorporated to a depth of 3 feet and from the curb line to a liner placed 3 feet from building faces and/or known
cellar access points. Part of this width is necessary due to the decreased availability of loam within structural
systems. The City is considering using Cornell mix soil, though sand-based structural soils and structural cells are
also under consideration. Structural cells are not appropriate in areas with many utilities, but elsewhere they have
the advantage of allowing standard planting soil to be placed in their voids and could be minimized to installation
only within the treeway, making them no more costly than structural soil that occupies a wider area.
SUSTAINABLE DESIGN
Part of the benefit of reducing space and pavement devoted to vehicles is that the space can be used to support a
more sustainable Main Street. More volatile weather and temperature changes due to climate change must also
be addressed through a street design that helps reduced greenhouse gas emissions while mitigating and
adapting to the impacts of heat and flooding. Some sustainable elements of the Main Street design include:
» Reducing the amount of heat-absorbing black asphalt through roadway narrowing, helping to mitigate
the urban heat island effect. Materials choices will further advance heat island mitigation.
» Canopy trees, once they are established, will form a more continuous canopy than exists now. This
helps to mitigate the urban heat island effect and filter air pollution while providing shade that makes
the street more comfortable. The canopy will help reduce summertime air conditioning needed in
adjacent buildings while blocking the winds that drive up heating costs in winter.
» Both trees and any understory planting will help support insect and bird habitat, with species choices
determining the level of impact.
» Post 25% submission, materials can be chosen based off their reduction of carbon emissions in
production and delivery.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 81
Some larger sustainable elements are also incorporated into the Main Street design. Stormwater Best
Management Practices (BMPs) are being used as feasible primarily to attenuate peak flows into the closed
drainage system and to capture and treat runoff. Treatment is important on Main Street as the City is required to
remove 80% of Total Suspended Solids (TSS) and 50% Total Phosphorus average annual loads per the
Environmental Protection Agency. The BMPs currently incorporated into Main Street include:
» Deep sump catch basins
» Bioretention areas including rain gardens
» A water quality swale
» Porous pavement
Understory planting will be included in stormwater infiltrating rain gardens to be located primarily in curb
extensions. A short water quality swale may be incorporated adjacent to Merrick Lane in the sidewalk amenity
zone, as this area has more serious grading challenges that require restriction of that zone to pedestrians. Plant
choices will be made to support pollutant removal in both this and the rain garden areas. Adequate pretreatment
and soil depth will be designed post 25% submittal.
Porous pavement is planned for the amenity zone to attenuate peak flow on the sidewalk and to filter TSS. The
water may also help benefit trees planted along the amenity zone (also called the treeway).
Besides stormwater BMPs, drainage and sewer systems are being fully updated. This is primarily in response to a
need for increased capacity. In the case of the drainage system, existing pipes are very undersized, and the
project area experiences flooding in some locations. With more intense storm and increased flows expected due
to climate change, the City is bypassing design to the standard 10-year storm and instead maximizing its capacity
to handle 25-year storms.
Finally, based on public input the City is exploring options for incorporating a geothermal heat array under Main
Street. This is meant to provide a source of renewable energy for the buildings along and adjacent to Main Street.
This would be a very long-term project, so generally the City is looking to ensure that a reconstruction of Main
Street does not preclude the installation of the heating system by ensuring 8-10 feet of space is left available near
the gas line. Other design considerations will be identified going forward.
TRUCK ROUTES
The heavy vehicle collisions at the bridge between Strong Avenue and Market Street/Hawley Street make up
approximately 7% of all collisions on Main Street (see section 3.2 Crash Analysis and Identified Deficiencies). A
number of options are available for installation to address and mitigate possible strikes to the bridge deck
including enhanced passive warning systems, sacrificial systems, and active warning systems. Passive systems,
like in existing conditions, typically consist of static signage, variable message signs, beacons or flashing signs,
and/or bridge markers. Sacrificial systems provide last-resort physical notifications and often consist of crash
beams or hanging chains that help prevent damage to the overhead structure, but often result in damage to the
heavy vehicle. Active warning systems can consist of GPS locators on driver vehicles that provide visual or audio
warnings activated upon approach to a low-clearance bridge. Alternatively, and as mentioned in the Route 9
Railroad Overpass Safety Study, a sensor system to detect high-clearance vehicles can alert drivers once
triggered. This method is often high-cost and accuracy may be limited.
6.6 SAFETY ENHANCEMENTS
This project proposes to significantly increase safety for all roadway users within the project area. A summary of
all the proposed safety enhancements from the RSA, with responses indicating which treatments were selected

OPERATIONAL ANALYSIS

7 TRAFFIC SIGNAL PHASING
ALTERNATIVES AND OPERATIONAL
ANALYSIS
The vehicular, pedestrian, bicycle, and transit needs throughout the corridor call for a customized treatment at the
four signalized intersections. The following section discusses the phasing alternatives evaluated and the preferred
phasing sequences at each signalized intersection.
7.1 BASIC SIGNAL STRATEGY
The primary strategies evaluated at each intersection include pedestrian and bicycle phasing options, phase
separating turns, and right turn on red operations.
PEDESTRIAN PHASING
Two phasing options are typically used for pedestrian phasing at signalized intersections: exclusive and
concurrent. Each serves pedestrians with varying degrees of separation from conflicting vehicular movements
and each reserves their own implications for pedestrian delay.
Exclusive Phasing
Exclusive pedestrian phasing stops all vehicular traffic in all directions so people may cross along all crosswalks,
and if programmed, to cross diagonally through the middle of the intersection. This type of signal phasing grants
full separation and full priority to pedestrians where there are no conflicting vehicular turning movements
permitted. Stopping all vehicular movement for the duration of the time required to cross the longest leg or corner-
to-corner distance at an intersection often leads to high delay for both pedestrians and drivers.
Exclusive phasing offers no legal benefits to people biking. However, in practice exclusive pedestrian phasing is
generally used with discretion regardless of intended use. Today, a mix of behavior is currently observed on Main
Street, with some bicyclists waiting to use the vehicular traffic signals and others using the exclusive pedestrian
phase depending on when in the signal cycle they arrive at the intersection.
Concurrent Phasing
Concurrent pedestrian phasing provides pedestrians a WALK signal at the same time as a green light for parallel
vehicular movements. Concurrent phasing typically reduces the amount of delay both pedestrians and vehicles
experience at an intersection compared to exclusive phasing but requires turning vehicles to yield to pedestrians
in the parallel crosswalk. Leading pedestrian intervals (LPIs) provide a timed buffer to pedestrians, typically
between 3 and 7 seconds long, ahead of the concurrent vehicular movement. During the LPI, pedestrians can
enter the crosswalk before the vehicular movement begins, allowing them to establish their presence in the
crosswalk ahead of any conflicting turning movements.
Concurrent signal phasing offers the ability to formalize shared use of the pedestrian signal for both people
walking and biking. In accordance with the 2009 MUTCD, “the R9-5 sign may be used where the crossing of a
street by bicyclists is controlled by pedestrian signal indications.” In situations where potential conflicts between
people walking across the street and people making turning movements on bikes may be traveling through the
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 111
same phase, supplemental ‘BIKES YIELD TO PED’ (R9-6) are suggested to clarify priority for pedestrians over
people making turning movements on bikes.
Shared phasing between people walking and biking as described above also applies to situations where LPIs are
in use. All of the same benefits accrued to people walking with an LPI are similarly transferred to people biking in
this alternative, including reduction in delay and increased intersection visibility.
Concurrent Protected Phasing
While traditional concurrent phasing typically permits conflicting movements to turn across a parallel crosswalk,
concurrent protected pedestrian phasing eliminates all vehicle-pedestrian conflicts by introducing exclusive turn
lanes for all turning movements (e.g. no turning movements permitted from the same lane as a dedicated through
lane). This allows the signal phasing to be organized such that parallel crosswalks only run concurrently with
through movements while turning movements are restricted to fully protected phases. Similar to the scenario
described above, this phasing style offers the ability to formalize shared use of the pedestrian signal for both
people walking and biking for a movement that is fully protected from all motor vehicle traffic.
While concurrent protected phasing provides the separation benefits of exclusive phasing, the need for dedicated
turn lanes required to accommodate the signal phasing often has spatial impacts, particularly in regard to which
roadway user is allotted that space in a constrained environment. For example, concurrent protected phasing may
provide phasing separation for people walking and biking at an intersection but may come at the cost of being
unable to maintain dedicated bicycle facilities through an intersection, thus impacting network continuity.
Dedicated Bike Signals
Bicycle signals are used to both communicate clearly to a defined user group (people biking) and to reduce
conflicts by phase-separating bicycle movements. Bike signals can be especially helpful or even necessary for
locations with contraflow bike movements (for example on two-way separated bike lanes), locations with high
volumes of bike movements, and locations with high volumes of turning vehicles. Dedicated bike signals also offer
the ability to include leading bike intervals (LBIs) through an intersection, which operate similarly to leading
pedestrian intervals.
Bike signal equipment generally includes either an eight-inch circular indication with a required ‘BIKE SIGNAL’
sign (R10-10b) or a signal with dedicated bike faces (through Federal Highway Administration interim approval IA-
16). When bicycle signal faces are used, no conflicting vehicle movements are allowed, including permissive left
turns and right turn on red movements.
While there are many benefits to bike signals depending on context, none of the current phasing alternatives
include use of dedicated bike signals. In lieu of dedicated bike signals to provide control to the separated bike
lanes, the proposed signal phasing sequences include directing people biking through the intersection to use
pedestrian signalization with ‘BIKE USE PED SIGNAL’ signs (R9-5) for several reasons including overall project
equipment and maintenance cost, impacts to vehicle delay, and existing regulations for dedicated bike signals
which are currently undergoing revisions as part of the update to the MUTCD. In accordance with the 2009
MUTCD, “The R9-5 sign may be used where the crossing of a street by bicyclists is controlled by pedestrian
signal indications.” proposed arrangement will clarify and help guide desired behavior. For all approaches, ‘BIKE
YIELD TO PED’ signs (R9-6) are proposed to clarify priority for pedestrians over people making turning
movements on bikes.
PHASE SEPARATED TURNS
MassDOT’s Separated Bike Lane Planning and Design Guide (SBLPDG) provides recommendations for phase
separating movements that turn across a separated bike lane. The proposed signal phasing, described in the
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 112
following sections, maintains phasing separation where turning movement counts exceed the thresholds outlined
in Figure 50.
Figure 50. MassDOT SBLPDG Recommendations for Phase Separated Bicycle Movements31
While these guidelines primarily prioritize safety for people in the bicycle facilities, motor vehicles similarly benefit
from phase separation where a separated bike lane is present. Drivers turning across opposing lanes of traffic as
well as a bicycle facility must find a gap in multiple travel lanes, be they for people walking, biking, or driving. If the
driver attempted to turn through a perceived gap in motor vehicle traffic during a permitted left turn movement but
meets a person walking or biking in the crosswalk, they may slam on their brakes to avoid the person and
subsequently be hit by the opposing traffic in the lanes they attempted to cross. With phase separation, those
permitted movements and the conflict scenarios reliant on judging gaps in traffic are removed, granting people
walking, biking, and driving a safer roadway environment.
RIGHT TURN ON RED OPERATIONS
Bicycle movements along the separated bike lanes at signalized intersections are phase separated where turning
volumes exceed the thresholds in the MassDOT SBLPDG. The MassDOT SBLPDG also provides the
recommendation that right turns on red (RTORs) be restricted when there is a protected bike phase, right turns
are protected, or when there is a leading bike phase. As discussed in the following section, a number of the right
turn movements are proposed to be phase separated from adjacent crosswalks and bicycle movements,
suggesting that RTOR restrictions be imposed where not mandated already. Eastbound and westbound RTOR
operations are proposed to be restricted across the separated bike lane throughout the corridor, even where right
turns do not have a protected movement, to limit the number of conflicts between crossing pedestrians and
cyclists and those motorists. Additionally, at Market Street/Hawley Street, RTORs are proposed to be restricted
for the northbound and southbound approaches due to the limited sight lines. Table 20 provides a summary of the
existing and proposed RTOR restrictions throughout the corridor.

COORDINATION
The intersections of Main Street at West Street/Elm Street and at State Street/New South Street should operate
with the same cycle length to maintain coordination between the two signals. The intersections of Main Street at
King Street/Pleasant Street and Main Street at Market Street/Hawley Street are currently not coordinated, though
their proximity prompted evaluation of coordination separate from that of the two western intersections at West
Street/Elm Street and State Street/New South Street. Several cycle length options are available when
coordinating signals, including full-cycle coordination, two-thirds-cycle coordination, and half-cycle coordination.
Full-cycle coordination sees both coordinated intersections operate with the same cycle length, often with one
intersection offset to accommodate uni-directional flow between the intersections. Half-cycle coordination allows
one intersection to operate with half the cycle length of what is typically the larger intersection with more vehicle
input, allowing that half-cycle intersection to cycle through its phasing twice for every one time the full-cycle
intersection cycles. Similarly, two-thirds cycle coordination allows one intersection to cycle through its phases
three times for every two times the other intersection cycles. Half-cycle and two-thirds cycle coordination shorten
pedestrian delays at the intersection where a shorter cycle length can be accommodated, leading to a reduced
likelihood of noncompliance. The different coordination styles were evaluated at the western signalized
intersections and the eastern signalized intersections. Half-cycle coordination was ultimately applied to all peak
hours for the coordinated King Street/Pleasant Street and Market Street/Hawley Street intersections based on
vehicle capacity analysis and minimizing average pedestrian delay.
7.2 SIGNAL PHASING ALTERNATIVES
Traffic signal phasing alternatives at West Street/Elm Street and State Street/New South Street, King
Street/Pleasant Street, and Market Street/Hawley Street were vetted with the City of Northampton through a
series of technical memorandums. Each memo summarized existing conditions and RSA and Walk and Bike
Audit findings before proposing a set of alternative phasing options targeting the deficiencies identified and
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 114
encompassing the project goals to provide safety and access for all, promote a vibrant and attractive downtown,
and create a functional, enduing, and sustainable streetscape. The following section summarizes the alternatives
evaluated at each of the study area signalized intersections. West Street/Elm Street and State Street/New South
Street are grouped due to their proximity, and the preferred alternative is identified through correspondence with
the City of Northampton.
ANALYSIS METRICS
Each memo used traffic models to evaluate the vehicular operations and average pedestrian delay of existing and
proposed alternatives.
Motor Vehicle Capacity Analysis
Level of Service (LOS) is a performance measure that defines traffic operations based on the average amount of
time a vehicle waits at an intersection. For example, LOS A defines the condition with minimum vehicular traffic
delay, while LOS F represents the condition with significant traffic delay. The HCM states that “the existence of a
LOS F condition does not, by itself, indicate that action must be taken to correct the condition,” and proposed
traffic conditions reflect this approach by evaluating intersection performance measures not centered around
motor vehicle conditions, as described in the following section. Table 21 indicates the LOS conditions based on
average delay as defined by the Highway Capacity Manual (HCM).
Table 21. Level of Service Criteria
Level of Service Average Stopped Delay at Signalized
Intersection (seconds/vehicle)
Average Stopped Delay at
Unsignalized Intersections

A 0.0-10.0 0.0-10.0
B 10.1-20.0 10.1-15.0
C 20.1-35.0 15.1-25.0
D 35.1-55.0 25.1-35.0
E 55.1-80.0 35.1-50.0
F >80 >50.0
To compute the LOS and other performance measures, the HCM methodology was used. For the signalized
intersections, HCM 2010 methodology cannot be used since signals use standard National Electrical
Manufacturing Association (NEMA) phasing, so HCM 2000 methodology was used. Synchro 10 software was
used to apply these methodologies, which allows for inputs such as lane configuration, traffic volumes,
pedestrian/bicycle to vehicle interactions, and peak hour factors. In addition to estimating the delay and LOS at
intersections, Synchro 10 was used to estimate intersection queue lengths. Results were used to compare traffic
operations in existing and proposed alternative conditions to determine a preferred alternative.
In accordance with MassDOT guidelines, all intersection approaches for both existing and proposed alternatives
were evaluated based on the peak 15 minutes of data collected during the network peak hour. Existing traffic
signal timing and phasing were provided by the City of Northampton and are reflected in the Existing Conditions
analysis in each traffic technical memorandum. Calibrations and factors that influence traffic operations analysis
in Synchro 10 are summarized in Table 22.

Pedestrian Delay
Pedestrian LOS (PLOS) metrics are based solely on delay and the concepts and procedures in the Highway
Capacity Manual (HCM)32. Table 23, an excerpt from the HCM, provides PLOS criteria for signalized
intersections, along with pedestrian noncompliance likelihood guidance. When pedestrians experience more than
a 30 second delay, they become impatient, and are more likely to engage in risk-taking behavior. Average
pedestrian delay represents the average number of pedestrians anticipated to wait at a signal relative to the
average amount of time those pedestrians have to wait and is calculated using the equations below. An additional
4 seconds is included in the pedestrian effective green time to account for pedestrians who begin their crossing a
few seconds after the WALK indication has begun.

MAIN STREET AT WEST STREET/ELM STREET AND STATE
STREET/NEW SOUTH STREET
The proximity of the western intersections warrants coordination between the two signals to limit spillback of the
Main Street westbound approach to West Street and the Main Street eastbound approach to State Street/New
South Street. Alternative analysis vetted in the “Traffic Operations at Main Street at West Street/Elm Street and
State Street/New South Street” technical memorandum, attached in Appendix D, looked at four alternatives for
the intersection:
32 HCM 2000: Highway Capacity Manual. Washington, D.C.: Transport Research Board, 2000.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 116
» Alternative A, Preferred Geometry Phasing,
» Alternative B, Preferred Geometry Phasing with Volume Reductions,
» Alternative C, Preferred Geometry Phasing without the State Street Southbound Approach, and
» Alternative D, Additional Main Street Eastbound Through Lane.
Alternative A proposes converting the Elm Street eastbound approach to consist of a through lane and a
dedicated right turn lane to allow the right turns to be phase separated from the southern crosswalk and
eastbound separated bike lane. Phasing begins with the Main Street westbound left turn and through lane running
concurrently with the northbound right turn. Then the eastbound and westbound through movements operate
concurrent with the southern crosswalk before the eastbound right turn movement is provided a protected phase.
Finally, the West Street northbound approach runs concurrent with the western crosswalk. Phasing at Main Street
at West Street/Elm Street in Alternative A can be seen in Figure 51.
Figure 51. Alternative A Phasing at Main Street at West Street/Elm Street
The Main Street at State Street/New South Street preferred phasing has lead/lag left turn phasing for the
eastbound and westbound approaches, beginning with the Main Street eastbound through, eastbound left, and
State Street southbound right turn running concurrently with the crosswalk traversing New South Street and
eastbound separated bike lane. Once the southern crosswalk phase is complete, the Main Street eastbound right
turn runs concurrently with the eastbound and westbound through movements. Then, the Main Street westbound
left turn and through movements run concurrent with the New South Street northbound right turn. The crosswalk
traversing State Street and westbound separated bike lane also run concurrently with these phases. The New
South Street northbound approach then overlaps with the Main Street eastbound right and the eastern crosswalk,
followed by the State Street southbound approach and the western crosswalk. The diagonal crosswalk in existing
conditions is converted to two crosswalks, one across the western leg of Main Street at State Street/New South
Street and one across the eastern leg. Under these conditions, the eastbound and westbound left turn
movements no longer must be timed to accommodate crossing the diagonal crosswalk, and that additional time
can be reallocated to other movements. All crosswalks except the western crosswalk at State Street/New South
Street are on pedestrian recall. The western crosswalk is not on recall but the removal of the diagonal crosswalk
and the addition of the western crosswalk across Elm Street provides more traditional and consistent crossing
opportunities from the north side of the corridor to the south. Alternative A phasing at Main Street at State
Street/New South Street can be seen in Figure 52.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 117
Figure 52. Alternative A Phasing at Main Street at State Street/New South Street
Alternative B proposes the same phasing as Alternative A with a 10% volume reduction justified by the principles
of traffic evaporation and declining traffic volumes seen in historical counts within the project area. The alternative
sees the same phasing benefits of Alternative A with the added advantage of lower cycle lengths allowable with
the reduced traffic volumes.
Alternative C again proposes the same phasing at Alternative A with adjustments to account for the proposed
conversion of State Street to one-way northbound between Main Street and Center Street. The conversion from
the existing two-way operations removes the southbound approach at Main Street and allows vehicular capacity
demanded by the approach to be reallocated to the other movements at the intersection and the cycle length to
be lowered.
The final alternative evaluated introduces an additional eastbound through lane between West Street and
Masonic Street, requiring removal of the separated bike lanes in each direction west of Masonic Street.
Alternative D would see the Elm Street eastbound approach to West Street consist of a through lane and a
through/right turn lane as in in existing conditions, so that there cannot be phase separation for eastbound right
turning vehicles crossing the southern crosswalk. Phase separation for the southern crosswalk across New South
Street is maintained, but eastbound bicycles must travel within the vehicular travel lane.
All alternatives address deficiencies of the existing geometry and phasing by removing the diagonal crosswalk at
New South Street/State Street, phase separating the Main Street eastbound right turn onto New South Street,
and providing a crosswalk across the western leg of the West Street/Elm Street intersection. Toole Design’s
preferred phasing alternative is Alternative A/Alternative B due to the improvements to safety for all users and
support of project goals through phasing and geometric improvements. Alternative A is advanced through this
analysis to provide a conservative estimate of traffic operations at the western intersections. The proposed cycle
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 118
length at both intersections is 110 seconds in the morning and Saturday midday peak hours and 130 seconds in
the evening peak hour.
MAIN STREET AT KING STREET/PLEASANT STREET
The “Traffic Operations at Main Street at King Street/Pleasant Street” technical memorandum, attached in
Appendix E, evaluated two alternatives, both removing the exclusive pedestrian phasing at the intersection to
reduce average pedestrian delay experienced:
» Alternative A, Concurrent Pedestrian Phasing and
» Alternative B, Concurrent Protected Style Pedestrian Phasing.
Alternative A maintains the three lane approaches of King Street and Pleasant Street and provides a dedicated
left-turn lane and a shared through/right-turn lane to the Main Street eastbound and westbound approaches. The
Main Street through/right-turn lanes run concurrently with the northern and southern crosswalks and the King
Street southbound through and Pleasant Street northbound through run concurrently with the eastern and
western crosswalks. In this alternative, no left turns operate under permitted conditions across any crosswalk or
bike crossing and the northbound and southbound right turns are restricted to protected movements only. The
only movements permitted across the crosswalks are the Main Street eastbound and westbound right turns
across the northern and southern crosswalks. The crosswalks receive leading pedestrian intervals to mitigate
conflicts and allow people walking and biking to establish themselves in the crossing ahead of conflicting
movements.
Alternative B maintains three lanes for all approaches at the intersection: a dedicated left-turn lane, a through
lane, and a right-turn lane. Exclusive turn lanes for all movements allows all turns to be provided dedicated
phases and concurrent crosswalks to only run with through movements. People following pedestrian signals at
King Street/Pleasant Street therefore have no conflicts with turning motor vehicles while crossing any leg of the
intersection. Though the removal of conflicts is favorable for pedestrians, the additional right turn lanes along
Main Street lengthen their crossing distances and limits available space for expanding the sidewalk and/or
amenity zone.
Both alternatives reduce pedestrian delay at the intersection through converting the exclusive pedestrian phase to
concurrent pedestrian movements with little to no turning movement conflicts. Left turns are protected-only in both
scenarios, improving turning conditions for left turns that currently have to judge gaps in opposing travel lanes
during permitted movements. Upon request of the city following review of the memo, a third alternative was
introduced that mixed the two alternatives. In the third alternative, the Main Street eastbound approach follows
Alternative A geometry and phasing with a dedicated right-turn lane and the Main Street westbound approach
follows Alternative B with a shared through/right-turn lane, as shown in the phasing diagram in Figure 53. This
alternative has the same operational benefits for pedestrians and vehicles as Alternative A and Alternative B and
was therefore selected as the preferred alternative at Main Street at King Street/Pleasant Street. The proposed
cycle length at the intersection is 110 seconds in all peak hours.
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 119
Figure 53. Preferred Alternative (Mix of A and B) Phasing at Main Street at King Street/Pleasant Street
MAIN STREET AT MARKET STREET/HAWLEY STREET
The technical memorandum, “Traffic Operations at Main Street at Market Street/Hawley Street”, which can be
found attached in Appendix F, evaluated three traffic signal control and phasing options at the intersection with
respect to vehicular operations, pedestrian and bicycle facilities and operations, and safety analysis. The three
options reviewed were:
» Alternative A, Concurrent Pedestrian and Vehicular Phasing,
» Alternative B, Concurrent Pedestrian Phasing and Split Vehicular Phasing, and
» Alternative C, Unsignalized.
Alternative A maintains the existing vehicular phasing with Main Street eastbound and westbound approaches
running concurrently with the northern and southern crosswalks, and the Market Street and Hawley Street
northbound and southbound approaches running concurrently with the eastern and western crosswalks. Leading
pedestrian intervals (LPIs) are provided ahead of each phase to allow people using the crosswalks to establish
themselves in the crosswalks ahead of any conflicting vehicular movements.
Crash analysis at the intersection suggested that the skewed geometries of the northbound and southbound
approaches result in conflicts between left turning and through vehicles. Alternative B addresses this through split
phasing the northbound and southbound approaches, the Market Street southbound approach running
concurrently with the western crosswalk and the Hawley Street northbound approach running concurrently with
the eastern crosswalk.
Alternative C investigated removing the traffic signal at the intersection based on vehicular and pedestrian
volumes from 2019. The traffic signal warrants evaluated, the Eight-Hour Vehicular Volume warrant, the Four-
Hour Vehicular Volume warrant, and the Pedestrian Volume warrant, were not satisfied with existing or projected
data, suggesting that people driving or walking through the intersection do not experience excessive delay or
conflicts.
Alternative A addresses the northbound and southbound conflicts, maintains vehicular operations similar to
existing conditions, and maintains average pedestrian delay similar to existing conditions. Alternative B improves
on existing vehicular operations and reduces pedestrian delay through converting to concurrent pedestrian
crossings with LPIs, but does not address the northbound and southbound conflicts. While signal warrant analysis
determined the signal to not be warranted, signal removal may result in crashes often seen at unsignalized
intersections and does not address the northbound and southbound conflicts. Of the three alternatives evaluated
in the memo, Toole Design recommended Alternative A as the preferred phasing for the intersection. Upon review
of the technical memorandum, the City of Northampton decided to move forward with Alternative B with the
phasing depicted in Figure 54 due to the improved vehicular and pedestrian operations compared to existing
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 120
conditions and Alternative A. The proposed cycle length at the intersection is 55 seconds in all peak hours to
allow for half-cycle coordination with Main Street at King Street/Pleasant Street’s 110-second cycle length.
Figure 54. Preferred Phasing Alternative (Alternative B) at Main Street at Market Street/Hawley Street
7.2 SCENARIO ANALYSIS
The vehicular and pedestrian operations of the preferred phasing at each signalized intersection and the
geometric changes at the unsignalized intersections were evaluated and compared to the existing Main Street
conditions. The comparative analysis by means of motor vehicle LOS, delay, volume-to-capacity (v/c) ratio, 50th
percentile queues, and 95th percentile queues and average pedestrian delay is discussed in the sections provided
for each intersection for the morning, evening, and Saturday midday peak hours. Detailed Synchro outputs are
provided in Appendix G for the existing and proposed conditions.
Signalized Intersections
All study area intersections and individual movements operate at LOS D or better, except for the movements
noted throughout the following sections. FHWA’s Traffic Analysis and Intersection Considerations to Inform
Bikeway Selection guidance emphasizes that motor vehicle LOS alone does not accurately describe the value or
function of an intersection, and that other performance measures should be considered where the intersection is
used by more than just motor vehicle traffic. Per this guidance, the average pedestrian delay at the signalized
intersection in existing conditions is compared to proposed conditions and discussed for each signalized
intersection.
Main Street at West Street/Elm Street
All movements in all peak hours operate at LOS D or better with the exception of the Main Street westbound left
to West Street in the evening and Saturday midday peak hours which operates at LOS E (Table 24). The
movement has permitted/protected phasing in existing conditions and is changed to being a protected only
movement in proposed conditions per the MassDOT SBLPDG suggests phase separating the movement based
on left turning volumes across the eastbound separated bike lane. The resulting reduction in available green time
is likely the reason the movement sees higher delays relative to existing conditions. Restricting the westbound left
turn to protected-only eliminates the need for the driver to judge gaps in oncoming traffic to execute a turn.
For people using the crosswalks at the intersection, the average pedestrian delay of the southern crosswalk is
maintained compared to existing conditions in the morning and Saturday midday peak hours, as seen in Figure
55. The western and southern crosswalks in the evening peak hour see an increase in average pedestrian delay
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 121
experienced, though an PLOS E is maintained from existing to proposed conditions. The addition of the western
crosswalk in proposed conditions provides a crossing location where RSA attendees noted there to be high
occurrences of crossing against the signal. The western crosswalk reduces the crossing time for people
attempting to get from the southwest corner of the intersection to the north side. In existing conditions,
pedestrians must walk to the State Street/New South Street intersection to cross to the north side of Main Street,
but in proposed conditions they can do so along the western intersection.

Delay was balanced among all movements at the intersection by removing the diagonal crosswalk and
reallocating some of the time dedicated to the Main Street eastbound and westbound left turns that were paired
with it (Table 25). The LPIs at the intersection were also removed because high-volume turns across the northern
and southern crosswalks are phase separated in proposed conditions. As such, the only conflicting volume across
the northern and southern crosswalks it the Main Street westbound right turn across the northern crosswalk which
has less than 30 vehicles per peak hour. The New South Street right turn movement is also incorporated into the
signal compared to existing conditions where it is free running.
The Main Street westbound through and State Street southbound left-turn/through movements operate
overcapacity in all peak hours in existing conditions. In proposed conditions, the westbound through/right-turn
movement operates under capacity in all peak hours at LOS E in the morning and evening peak hour and LOS D
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 123
in the Saturday midday peak hour. The State Street southbound approach also operates under capacity in
proposed conditions in all peak hours.
The Main Street westbound left in all peak hours and the Main Street eastbound left in the evening and Saturday
midday peak hours operate at LOS E or F in all peak hours. Decoupling the eastbound and westbound left turn
movements from the diagonal crosswalk means their minimum green times are shortened and therefore they see
lesser green time in proposed conditions. The additional time gained from this is reallocated to other movements
to balance delay and maintain v/c ratios less than or equal to 1.00.
The Main Street eastbound through movement in all peak hours and the Main Street eastbound right turn
movement in the morning and evening peak hours operates at LOS E or F. The New South Street northbound
left-turn/through movement operates at LOS E or F in proposed conditions similar to existing conditions. Though
these movements operate at LOS E or F, their v/c ratios are less than 1.00 suggesting that the movements have
the ability to take on additional vehicles without excessive delay that could elongate the peak hour.
Pedestrians in all peak hours along all crosswalks see average pedestrian delays less than PLOS E similar to
existing conditions (Figure 56).

Main Street at King Street/Pleasant Street
All turning movements except for the Main Street westbound right turn are restricted to protected movements at
the intersection. Removing the permitted movements and maintaining right-turn-on-red restrictions relative to
existing conditions reduces the amount of available green time for those movements. The following turning
movements operate at LOS E or F in proposed conditions as a result (Table 26):
MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 125
» Main Street eastbound left turn in all peak hours,
» Main Street eastbound right turn in the evening and Saturday midday peak hours,
» Main Street westbound left turn in the Saturday midday peak hour,
» Pleasant Street northbound left turn in the evening peak hour,
» King Street southbound left turn in the morning and evening peak hours, and
» King Street southbound right-turn in the evening and Saturday midday peak hours.
Despite operating at LOS E or F, the movements all operate under capacity with volume-to-capacity ratios less
than 1.00. In addition to those turning movements, the Main Street westbound through/right-turn operates at LOS
E in all peak hours due to changes in lane assignment and signal operations to improve safety. The King Street
southbound through movement operates at LOS E or F in all peak hours similar to existing conditions.
In existing conditions, pedestrians are served with an exclusive pedestrian phase that is timed to allow
pedestrians to cross one leg of the intersection at a time despite observations seeing people cross diagonally.
The exclusive pedestrian phase’s clearance time is approximately 13 seconds shorter than what is required to
cross the longest distance at the intersection, approximately 130 feet from the northeast to the southwest corner.
As such, pedestrians are supposed to cross one leg of the intersection at a time, which could take approximately
168 second in the evening peak hour. The average pedestrian delay in existing conditions to cross just one leg of
the intersection is 60 seconds, or PLOS F. With the introduction of concurrent pedestrian phasing, the time
dedicated to the exclusive pedestrian phase can be reallocated to vehicle movements, allowing the cycle length to
decrease and reduce the average pedestrian delay to between 41 and 45 seconds, or PLOS D, for all crosswalks
in all peak hours (Figure 57).

Unsignalized Intersections
Main Street at Masonic Street
The Masonic Street southbound approach operates at LOS E in the evening peak hour in proposed conditions
and LOS F in the Saturday midday peak hour in existing and proposed conditions. The removal of one travel lane
in each direction likely increases the density of vehicles along Main Street, making it more difficult to finds gaps in
traffic. The proposed changes will simplify this turning movement, as vehicles attempting to turn left from Masonic
Street no longer have to judge gaps in two opposing lanes of traffic, the crosswalk across the eastern leg of the
intersection, as well as the traffic in the lane they are trying to enter. The narrowed cross section of Main Street
limits the number of conflicts side street approach drivers must navigate and is also expected to reduce the
speeds of through traffic.

Main Street at Old South Street
The Old South Street northbound left turn operates at LOS F in the proposed conditions evening peak hour. The
northbound right turn continues to operate at LOS F in proposed conditions as in existing conditions in the

section increases the density of vehicles along Main Street, which results in fewer gaps for drivers turning left

8 TRAFFIC MANAGEMENT
During the construction of the proposed project, at least one lane of traffic in each direction will be maintained on
Main Street. Traffic signals will be maintained in operation to the greatest extent practicable throughout the project
duration. Parking along Main Street may be temporarily removed during construction on the side of the street
being constructed, or to provide adequate space for temporary travel lanes. Access to all properties on the
corridor will be maintained throughout project construction.
An important component of the Traffic Management Plan will be public and stakeholder outreach to ensure that
those affected by the project are aware of the construction activities and phasing. The Traffic Management Plan
will be developed in the next phase of the project.
Figure 59 below, from the MassDOT Project Development Design Guidelines33, shows the hourly capacity for
different construction scenarios.
Figure 59. MassDOT PDDG Average Work Zone Capacities
Table 34 provides estimated design hour volumes and direction peak hour volumes in the construction area and
compares them to the estimated work-zone capacity for the appropriate conditions. For Main Street, it is assumed
that the existing configuration of two lanes in each direction will be reduced to one lane in each direction.

MAIN STREET | FUNCTIONAL DESIGN REPORT
TOOLE DESIGN | 136
Currently, there is expected to be four different phases for construction. Phases are guided by work zone
capacities, as outlined in Figure 59, the existing condition of the roadway, and the proposed work already
constructed previous to any stage.
Stage 1 will include all underground utility work including but not limited to work on drainage, stormwater,
conduits, and sewers. This will take place before the moving of curb lines and resurfacing of the road.
Stage 2 will maintain one lane in each direction during construction. Lanes will be shifted to the northern side of
the corridor while construction on sidewalks and the roadway occurs on the southern portion of Main Street.
Pedestrian access to the adjacent properties will be maintained during construction while parking on the south
side will be prohibited to allow room for construction.
Stage 3 will maintain one lane in each direction during construction. Lanes will be shifted to the southern side of
the corridor while construction on sidewalks and the roadway occurs on the northern portion of the corridor.
Pedestrian access to the adjacent properties will be maintained durcing construction while parking on the north
side of the corridor will be closed to maintain room for construction.
Stage 4 will open up the road and parking to its proposed condition. Stage 4 work will include landscaping and
any remaining striping or miscellaneous work remaining on Main Street.
Detailed exhibits of each stage will be provided in the 75% submission of this report.

Pedestrian Improvements
Corridor-wide Recommendations
1. Narrow Main Street to shorten crossing distances
by installing curb bump-outs and pedestrian
refuge islands. The streetscape design needs to
accommodate people using transit, riding bicycles,
walking, and driving cars.
2. Improve sight distance for pedestrians by
removing parking with 20 feet of crosswalks.
3. Evaluate signal timing for consistent pedestrian
phasing and upgrade pedestrian signal equipment
to include countdown indications and accessible
pedestrian signals (APS).
4. Enforce ordinances that keep sidewalk walking
zones clear. Educate business owners and event
promoters about appropriate location of signage
and tables.
5. Upgrade all curb ramps and install detectable
warning strips to comply with accessibility
requirements on all sidewalks along the corridor.
Northampton is one of 18 communities participating in the MassDOT multi-disciplined program to improve bicycle
and pedestrian safety in Massachusetts. One of the components of the MassDOT program is to conduct walk and
bike assessments that identify infrastructure challenges to biking and walking, and recommend short- and long-term
improvements. These assessments are also a means of building local knowledge of the importance of well-designed
bicycle and pedestrian facilities. WalkBoston and MassBike conducted an assessment of Main Street in downtown
Northampton.

1| Northampton Walk/Bike Assessments | Final Draft
WalkBoston and MassBike conducted an assessment of pedestrian and bicycle infrastructure along Main
Street in the City of Northampton on October 23, 2015. The assessment focused on Main Street (Route 9)
through downtown Northampton. The study area included the downtown corridor between the signalized
intersections of Main Street at West Street (Route 66) and Main Street at Pleasant Street/King Street (US
Route 5). The assessment was conducted in October in order to capture conditions during which the local
colleges were in session, when walking behaviors were highest, and to capture the behaviors of the wide
variety of users.
Key Findings
During the Main Street assessment, several key themes were repeated from members of the assessment
team. Team members praised the high quality walking environment through downtown Northampton,
noting the vibrant street activity and wide comfortable sidewalks separated from traffic by parking. It was
repeatedly noted however that crossing Main Street can be difficult given the wide street section, which
exceeds 100 feet curb to curb in some locations. Other issues that make crossing difficult include multiple
undefined lanes and poor sight distance resulting from adjacent parked cars. The crash data supports
these observations, indicating multiple crashes involving pedestrians as well as rear-end crashes resulting
from vehicles yielding at the crosswalks. To address these concerns, the team’s key recommendations
include reducing the length of crosswalks through roadway narrowing, curb extensions, and refuge
islands; improving sight distance through the removal of key parking spaces; improving accessibility at
intersections; and upgrading pedestrian signal equipment at signalized intersections.
Team members noted that access to and from downtown via bicycle is served by New Haven and
Northampton Canal Line Rail Trail that provide excellent access from neighborhoods northeast and
southwest of downtown, as well as bike lanes on Elm Street (Route 9) to the west and South Street to the
southwest. No bike facilities are provided within the study area and crash data indicated several bike
crashes including one fatality at the Pleasant Street/King Street intersection. Members of the team
observed that the wide undefined travel lanes, head-in angle parking, and complex intersections are
challenging for people on bikes. It was also noted that there is insufficient bike parking throughout the
study area, as multiple bikes were observed locked to railings and sign posts. To address these issues, key
recommendations include narrowing the roadway to provide separated bike lanes; installing bike parking;
and upgrading intersections to provide enhanced bicycle treatments and/or protected intersection
treatments.
2| Northampton Walk/Bike Assessments | Final Draft
Summary of MassDOT Bicycle and Pedestrian Safety and Awareness Program
The City of Northampton is one of the 18 communities participating in the Massachusetts Department of
Transportation’s (MassDOT) multi-disciplined program to improve bicycle and pedestrian safety in
Massachusetts in 2015. One of the components of the MassDOT program is to conduct walk and bike
assessments. The assessments have three goals:
1. Foster an awareness of the infrastructure elements which contribute to the biking and walking
environment;
2. Evaluate the safety and quality of the biking and walking environment along the route; and
3. Recommend short and long-term infrastructure improvements.
The assessments are not meant to be a complete inventory of infrastructure deficiencies, nor are they
meant to provide specific designs for every improvement. WalkBoston and MassBike lead the assessments
as a means to build local capacity for improving the built environment for walking and biking. This report
may be used as a resource for municipal staff, traffic engineers, and design professionals who
municipalities may engage to design and implement policies, programs, and infrastructure improvements.
The Northampton Police Department received a grant to conduct enforcement and awareness activities
at specific intersections and along identified corridors known to have high incidences of bicycle and
pedestrian crashes or violations. Police Officers are stopping all road users (drivers, bicyclists, and
pedestrians) who are engaging in dangerous behaviors for three reasons:
1. To inform the road user of the rules of the road;
2. To determine if there is a built environment (or infrastructure) reason that someone is not
following the rules; and
3. To gather qualitative data about the reasons why people are behaving the way they are.
The data collected from the police coupled with the results of the infrastructure assessments will identify
deficiencies and propose recommendations to improve the safety and quality of the walking and biking
environment in Northampton.
Toole Design Group (TDG) is working with WalkBoston and MassBike to complete the assessment reports.
TDG prepared this report which summarizes the observations made by members of the assessment team
and makes recommendations for improvements to the built environment to increase walkability and
bikeability. The observations vary from specific infrastructure deficits, such as faded crosswalks or uneven
sidewalks, to general comments on traffic speeds or land use patterns (e.g., vacant storefronts). Likewise,
the recommendations range from specific fixes (e.g., paint crosswalk) to suggestions for further study
(e.g., evaluate the feasibility of installing raised crosswalks) to non-infrastructure items such as education
and enforcement.

Assessment Location
WalkBoston, MassBike, and MassDOT met with representatives from the City of Northampton to identify
and choose appropriate locations for the walk and bike assessments funded through this MassDOT safety
program. The starting points for identifying the proposed locations included the Highway Safety
Improvement Program Top five percent high-crash clusters involving bicycle and pedestrian-related
fatalities and injuries, and the locations selected by the Northampton Police Department for awareness
and enforcement activities under this program; Figure 1 illustrates these locations. One of the goals of
this program is to identify if the built environment or infrastructure is contributing to the high incidence
of crashes and/or bad behavior in the described locations.
4| Northampton Walk/Bike Assessments | Final Draft
The discussions quickly centered on the challenges bicyclists and pedestrians face on Main Street,
especially for bicyclists and crossing pedestrians. While the area as a whole has excellent bicycling and
walking infrastructure, there are safety issues at some of the intersections and within the roadway. The
high-crash cluster analysis revealed that the Main Street corridor experiences a very high rate of
crashes; the corridor includes three crash clusters:
2012 HSIP Pedestrian Cluster - Main Street in the study area and segments of King/Pleasant Street;
2012 HSIP Bike Cluster - Main Street in the study area plus a segment of Pleasant Street; and
2012 Top 200 Intersection Cluster - Ranked 92 - Main Street from Center Street to Market Street.
With the goal of improving safety in Northampton, Main Street was selected for this assessment. The
limits of the area analyzed during the assessment begin at the West Street (Route 66) intersection to the
west and terminate at the Pleasant Street/King Street (US Route 5) intersection to the east. The Main
Street corridor was the subject of a design charrette run by Nelson/Nygaard in March, 2011. The study
discussed three major concerns which continue to be relevant today:
Wide 4-lane cross-section;
Large intersections with long crossing distances; and
Inhospitable biking environment.
Figure 1 - Assessment Area Map
5| Northampton Walk/Bike Assessments | Final Draft
The proposed solutions included creating a bike boulevard, installing reverse angle parking, and widening
sidewalks. These ideas continue to be discussed among City staff and were considered during the
assessment. In 2013, the Main/Elm/State/New South/West Street intersection received approval for
federal aid highway funding in excess of $1 million. The City is rethinking their proposal and considering
resubmitting for additional funding to address the issues that are corridor-wide. There is some hesitancy
to implement short-term solutions, such as curb extensions or travel lane adjustments, just to remove
them once a clear vision for the Main Street corridor is fully formed. This assessment is a means of
soliciting new ideas and validating previously submitted ones to build a safer Main Street for people
walking, riding bikes, and driving.
While bike and walk assessments are often conducted independently, the Northampton representatives
felt that a complete streets approach – that is looking at the patterns of all road users – would be most
appropriate at this location and consistent with the Northampton Complete Streets policy, adopted in
2005. Therefore, this report addresses both pedestrian and bicycle accommodations.
The assessment was conducted on Friday, October 23, 2015, and took approximately three hours. Before
the assessment, WalkBoston and MassBike presented an introduction about the assessment process and
a brief summary of pedestrian and bicycle infrastructure. The group spent about an hour and a half in the
field and regrouped for a discussion of observations and potential recommendations.
During the assessment, the topics covered included the potential for narrowing and reducing the number
of travel lanes, calming traffic, providing improved accessibility at intersections, providing improved
crossing opportunities throughout the corridor through narrower lanes and improved sight distance, and
providing bicycle facilities and bike parking through downtown. The following section describes both the
observations and recommendations by location. The locations include area-wide recommendations as
well as location specific recommendations.
Main Street Corridor Assessment
The study area for the Main Street assessment shown in Figure 1 includes Main Street from West Street
(Route 66) to King Street/Pleasant Street (US Route 5), including the following intersections:
Main Street/Elm Street (Route 9) at West Street (Route 66);
Main Street at State Street/New South Street (Route 10);
Main Street at Masonic Street;
Main Street at Crafts Ave/Crackerbarrell Alley;
Main Street at Old South Street;
Main Street at Center Street;
Main Street at Gothic Street; and
Main Street at King Street (Route 10, US Route 5)/Pleasant Street (US Route 5).
6| Northampton Walk/Bike Assessments | Final Draft
Main Street is a City-owned roadway classified by the MassDOT Office of Transportation Planning as a
principal arterial, and carries state numbered routes 9 and 10 through downtown. Route 9 is a major east-
west connector across the state, beginning to the west in Pittsfield and terminating to the east in Boston.
Locally, Route 9 provides access to Williamsburg to the northwest and Hadley to the east. Within the study
area, the roadway provides a wide cross-section with undefined lanes, on-street parking, and a posted
speed limit of 25 miles per hour. Drivers typically form two lanes in each direction through the study area.
Route 10 is a north-south route, connecting to Connecticut and Vermont, roughly paralleling I-91.
Corridor-wide Observations and Recommendations
The team noted that sidewalks throughout the study area are generally wide and in good condition.
Pedestrian volumes and activity along the sidewalks is busy, and pedestrians are frequently observed
crossing the roadway both within and outside of the marked crosswalks. Outdoor dining is encouraged
and occurs often along Main Street, which adds to the vibrancy of the area. Many establishments
encroach on the walking zone of the sidewalk despite the ordinances which regulate appropriate dining
areas. Sandwich boards and other temporary signage also interrupt the sidewalk, which may be just an
annoyance for some, but a barrier for others. The team noted that more needs to be done to ensure that
the walking zone remains free of obstructions.
Travel speeds through downtown generally appear to be at or below the speed limit, and most drivers
were observed to yield at uncontrolled crosswalks. The team noted several issues, however, with
crosswalks in general through downtown, including pedestrian ramps which do not meet accessibility
standards, wide crossings that result in difficulty for disabled pedestrians, cars parked adjacent to
crosswalks obstruct visibility to pedestrians waiting to cross, and multiple lanes create multiple-threat
scenarios for crossing pedestrians. Members of the team observed that some drivers in the second travel
lane did not stop when the driver in the first lane had stopped, as they may have thought the stopped
vehicle was waiting to park.
Members of the team suggested narrowing the roadway to provide one consistent travel lane throughout
the study area, plus turn lanes at key intersections as needed. Parking should be removed adjacent to all
crosswalks (within 20 feet) in order to maintain safe sight distance between pedestrians and vehicles. As
a long term measure, constructing curb extensions at each crosswalk will further enhance sight distance
for all users. Pedestrian crossing islands should also be considered at major mid-block crossings.
Pedestrian signal phasing is inconsistent throughout the Main Street corridor. Some signals are
concurrent, others are exclusive. Some signals are activated with pedestrian push buttons, others are not.
For those who live in Northampton, these details are known, but for visitors, vehicular traffic movements
are unpredictable and potentially dangerous, as pedestrians may not expect different operations between
adjacent intersections. As the traffic signal equipment is upgraded, pedestrian countdown signals with
Accessible Pedestrian Signals (APS) should be installed and the consistency of phasing should be studied.
7| Northampton Walk/Bike Assessments | Final Draft
Members of the team noted that most of the pedestrian ramps within the study area do not meet
accessibility standards. The City should reconstruct the curb ramps as part of ongoing maintenance work
to provide compliant ramps including appropriate level landing areas and detectable warning surfaces.
Members of the team observed several large
tractor trailer trucks and logging trucks
traveling through downtown which did not
appear to be local trips. City staff noted that
large vehicles typically have to detour up King
Street to Damon Road in order to avoid the low
railroad bridge east of King Street and
continue east on Route 9 towards Interstate
91. Given that the existing through route is
extremely indirect and that the heavy truck
volumes are incompatible with the heavy
volumes of people walking and on bikes, the
City and MassDOT should explore strategies to
reroute through trucks away from Main Street
through downtown. It would be necessary to
provide a sufficient alternate route for through trucks on Route 9.
The team also noted that no dedicated bike facilities are provided on Main Street east of New South
Street, however bicyclists were observed traveling on the roadway and on the sidewalk. Many bikes were
observed locked to bike racks, railings, and signs. Members of the team suggested installing bike lanes or
separated bike lanes as part of the previously proposed travel lane reduction. Separated bike lanes may
be provided at low cost by shifting the parking away from the curb, providing a bike facility along the curb
line separated from traffic by the parked cars. If bike lanes are proposed between the parking and travel
lanes, the angle parking should be reversed to provide back-in parking to provide safe sight distance
between drivers exiting spaces and bicyclists in the bike lane. The team discussed the previous trial that
Northampton conducted for reverse angle parking in which drivers did not understand how to properly
utilize the spaces. Members of the team noted that if reverse angle parking is implemented, it must be
provided for all angle parking spaces in order to minimize confusion.
Lastly, members of the team noted that access routes to and from the nearby trail network were not
clearly marked, and that cyclists and pedestrians may not be aware of the best routes to and from
downtown. The City should consider installing wayfinding signage at key locations on and near Main Street
as well as on the trails to direct users to and from the trails.
Figure 2 - Logging trucks pass through the New South Street
intersection on Main Street.
8| Northampton Walk/Bike Assessments | Final Draft
Short-term Recommendations:
Remove parking adjacent to crosswalks to improve sight distance.
Reduce the number of travel lanes on Main Street to provide a single lane in each direction plus
turn lanes at key intersections to minimize queueing.
Install bike facilities on Main Street through the study area.
o Alternative 1: Separated bike lane between the existing angled parking spaces and the
curb.
o Alternative 2: Bike lane between parking and the travel lanes including a conversion to
back-in angle parking.
o Alternative 3: Two-way center running separated bike lane (cycle track) including left turn
restrictions at side streets.
Install bike parking in convenient and visible locations throughout the study area.
o Single bike racks should be placed frequently within the furniture zone on sidewalks.
Racks should be placed such that locked bicycles do not obstruct the sidewalks or adjacent
parking stalls.
o High capacity, covered bike parking should be located in a secure, visible location.
Reconstruct curb ramps to meet accessibility standards.
Enforce ordinances that keep the sidewalk walking zones clear. Educate business owners about
appropriate locations for signage, seating, and other items placed on sidewalks.
Install bike wayfinding signage directing bicyclists to access points for the adjacent trail network.
Install pedestrian countdown timer indications and accessible pedestrian signals (APS).
Revise signal timing to provide consistent pedestrian timing at all signalized intersections where
possible.
Long-term Recommendations:
Construct curb extensions and consider constructing pedestrian crossing islands at all unsignalized
crosswalks.
Construct street or sidewalk level separated bike lanes (cycle tracks) with curb separation from
adjacent parking. If separated bike lanes are constructed at sidewalk level, there must be
horizontal separation between the bike lane and the sidewalk. The horizontal separation strip
needs to include vertical elements, such as street lights, trees, signs, benches, etc, to ensure that
bikes and pedestrians remain separated.
Implement a truck restriction on Main Street through downtown while maintaining local truck
access. This will require that the City develop an alternate route for through trucks on Route 9. A
truck restriction will require approval from MassDOT.
9| Northampton Walk/Bike Assessments | Final Draft
Intersections: Main Street/Elm Street at West Street and at State Street/New
South Street
Existing Conditions
Elm Street/Main Street at West Street and
Main Street at State Street/New South Street
is a dual intersection controlled by two traffic
signals. Main Street is aligned on a curve
through the intersection with a significant
down grade from west to east. The traffic
signal provides a complex signal phasing
scheme including a protected left turn phase
from Main Street to State Street, a protected
plus permitted left turn phase from Main
Street to West Street, and concurrent
pedestrian phases.
Members of the team noted that the diagonal
crosswalk across the State Street intersection
has faded and not been replaced, however, pedestrian signal equipment provides a protected phase
concurrent with the Main Street Street left turn phase. Members of the team noted that no crosswalk is
provided across Main Street on the west side of State Street or on either side of West Street.
Bike lanes are provided on Elm Street west of
State Street/New South Street. The eastbound
bike lane includes green paint through the
intersection of West Street to highlight the
conflict zone. Members of the team noted that
eastbound vehicles on Main Street that plan
on turning right at New South Street
frequently transition through the bike lane
over a long distance due to the road alignment
and curvature, creating a large conflict zone.
The eastbound approach to State Street/New
South Street also provides a bike box across all
four lanes, however, the markings are faded.
Crash data indicate that there were three pedestrian involved crashes at the intersections during the
period analyzed, all of which involved pedestrians in the crosswalks. There were also three bicycle
involved crashes during the period analyzed, each involving a turning vehicle and a bicycle. All of the
pedestrian and bicycle involved crashes resulted in injuries.

intersection on Main Street.
Figure 4 - Bike lane intersection markings transition through the
West Street intersection.
10| Northampton Walk/Bike Assessments | Final Draft
Observations and Recommendations
Members of the team noted that the curvature of the roadway through the West Street intersection and
the angle of the West Street approach may confuse some left turning drivers and lead them to believe
they have the right-of-way through the intersection. The City should consider extending the median and
modifying the curb geometry through the intersection to better define the yield point for left turning
vehicles. The City should also consider providing flashing yellow arrow indications for the left turn
movement during the permissive turn phase to further inform drivers to yield when turning.
Members of the team noted that no crosswalks are
provided west of New South Street until Bedford Terrace,
west of the study area. The City should consider installing
crosswalks, ramps, and pedestrian signals across Main
Street at one or both corners of West Street in order to
serve pedestrians who wish to cross between
destinations on West Street and on the north side of
Main Street. The City should also restripe the existing
diagonal crosswalk across Main Street at State Street.
Members of the team also noted that vehicles turning
right from Main Street at New South Street often make
the movement at a high speed during the concurrent
pedestrian phase due to the large curb radius and wide
cross-section of both roads. City staff noted that a
dynamic “YIELD TO PEDESTRIANS” sign has previously
been operated at this location, however, was deactivated
due to traffic congestion issues. The City should consider
reconstructing the southwest corner of the intersection
with New South Street to reduce the curb radius and
possibly include a curb extension, reducing the speed of turning vehicles. The City should also consider
narrowing the intersection by removing or modifying the channelized right turn island and reducing the
corner radius. The team also noted that the signal indications for the right turn movement are unclear, as
the signal displays a through green arrow during the Main Street through phase. This provides no clear
guidance for drivers turning right.
Members of the team noted that the long cycle length for the traffic signals frequently results in high
delays which sometimes causes aggressive driving and red light running. The City should consider revising
the signal timing where feasible to reduce cycle lengths, allowing for more frequent crossing opportunities
for pedestrians and reduced red light times for drivers.

Street.
11| Northampton Walk/Bike Assessments | Final Draft
Members of the team observed that the existing signal equipment does not provide accessible pedestrian
signal (APS) control and that the pedestrian signals do not include countdown timers. The City should
consider upgrading the signal to provide APS equipment and countdown indications.
Members of the team noted that vehicles turning right to New South Street frequently make the transition
across the existing bike lane over a large distance, creating an undefined conflict zone for people on bikes.
The City should consider removing the right turn lane if traffic capacity allows or modifying the geometry
and markings to provide a protected intersection treatment, which would tie in to the previous
recommendation to provide separated bike lanes through the study area.
Members of the team noted that the wide, multi-lane approaches make it difficult for bicyclists to make
the left turn to State Street or New South Street, especially for bicyclists who arrive on green and are
unable to use the eastbound bike box. The City should consider installing two-stage turn queue boxes at
the State Street and New South Street to allow bicyclists to make the left turn during the side street green
phase. The city should also restripe the existing bike box and install green pavement markings.
Short Term Recommendations
Restripe the existing diagonal crosswalk at State Street.
Install flashing yellow arrow signal phasing at West Street.
Revise traffic signal timing to reduce cycle lengths.
Install two-stage turn queue boxes.
Upgrade the signal to provide APS equipment and pedestrian countdown indications.
Restripe the existing bike box and add green pavement markings.
Long Term Recommendations
Reconstruct the two intersections to provide the following measures:
o Reduced number of lanes where capacity allows;
o Reduced corner radii, removal or modification of the channelized turn island, and curb
extensions where feasible;
o New crosswalks across Main Street and Elm Street at West Street;
o Protected intersection geometry with bicycle signal control for through bicyclists; and
o Improved geometry for left turns.
Intersection: Main Street at Masonic Street
Existing Conditions
Masonic Street is two-way with parking on the west side. Crosswalks are provided across Masonic Street
and the east leg of Main Street. Members of the team noted that the number of lanes at the Main Street
crosswalk is undefined. West of the crosswalk, two striped through lanes and a right turn lane are provided
at State Street, however, no lane striping is provided at Masonic Street. The existing section at Masonic
Street provides approximately 45 feet between parking lanes, allowing for four lanes of traffic.
12| Northampton Walk/Bike Assessments | Final Draft
Crash data indicate that there were three pedestrian involved crashes at the intersection with Masonic
Street during the period analyzed. Each of the crashes involved a pedestrian within the crosswalk across
Main Street and all resulted in injuries.
Observations and Recommendations
Members of the team noted that parking
adjacent to the crosswalk on the eastbound
and westbound approaches limits sight
distance for pedestrians. The City should
consider removing one parking space on each
approach to provide sufficient sight distance
for pedestrians crossing Main Street. Members
of the team also observed that the existing bus
stop on Main Street eastbound west of
Masonic Street is heavily utilized, and that the
narrow sidewalk has limited space for
pedestrians to disembark from the bus,
especially when the wheelchair loading ramp
was deployed from the bus. Construction work
is ongoing for the adjacent park, and it is expected that the park will include a bus shelter, wider sidewalk
facilities, and bike parking.
Members of the team noted that buses stopping at the bus stop adjacent to Masonic Street conflict with
through bicyclists. Given the high volume of buses stopping at this location, consideration should be given
to providing a floating bus stop treatment as part of a larger project to provide separated bike lanes along
the Main Street corridor.
Short Term Recommendations
Remove parking adjacent to the crosswalk.
Install a bus shelter as part of the ongoing park improvement project.
Long Term Recommendations
As part of the larger recommendation to provide separated bike lanes through downtown,
consider providing a floating bus stop.

13| Northampton Walk/Bike Assessments | Final Draft
Intersections: Main Street at Crafts Ave/Crackerbarrell Alley, at Old South
Street, and at Center Street
Existing Conditions
The intersections of Main Street at Crafts Ave/Crackerbarrell Alley and at Old South Street are both
unsignalized, with STOP control provided on the northbound Old South Street approach. Crackerbarrell
Alley is one-way away from the intersection, providing shared vehicle and pedestrian access to the rear
parking lot. Crafts Ave is one-way away from the intersection, with angle parking provided on the west
side south of the intersection. Old South Street is one-way approaching Main Street, with separate left
and right turn lanes at the intersection approach and parallel parking provided on the east side.
Crosswalks are provided across the side street approaches and across Main Street at the west corner of
Crafts Ave and the east corner of Old South Street. Parallel parking is provided on both sides of Main
Street west of Crafts Ave while angle parking is provided on both sides of Main Street east of Crafts Ave.
The intersection of Main Street at Center Street is unsignalized. Center Street is a two-way street with
parallel parking provided on the west side. Crosswalks are provided across the Center Street approach
and across Main Street on the west corner.
The crash data indicate that there were two pedestrian involved crashes during the period analyzed, both
involving a pedestrian crossing Old South Street, one of which resulted in an injury. There was one bicycle
involved crash at the intersection with Crafts Ave which also resulted in an injury.
Observations and Recommendations
Members of the team noted that Main Street is extremely wide at the unsignalized crossings which creates
several operational and safety issues for crossing pedestrians. The roadway is 92 feet wide at the
crosswalk east of Old South Street, resulting in unexpected vehicle conflicts, long crossings, and visibility
issues. Pedestrians hear and feel the traffic speeding up behind them while still in the crosswalk which is
disconcerting. Drivers experience delays at the crosswalk due to the long crossing distance for pedestrians
as well. Some drivers stop when seeing a pedestrian in the crosswalk in the opposite lanes, while others
continue through the crosswalk knowing that the pedestrian will not reach them for several seconds.
These potential double threat locations cause pedestrians to move even slower across the street. As
previously noted, the City should consider narrowing the roadway throughout this segment to provide
improved pedestrian and bicycle facilities.
14| Northampton Walk/Bike Assessments | Final Draft
Members of the team noted that the existing
parking, sidewalk furniture, and roadway
geometry at the Crafts Avenue intersection
results in poor sight distance and high vehicle
turning speeds which impact both crosswalks.
The City should consider removing the two
parking spaces and relocating sidewalk furniture
in front of City Hall in order to improve sight
distance to both crosswalks. In the long term,
the City should consider reconstructing the
south side of Main Street to provide curb
geometry that follows the curvature of the
roadway and provides a reduced turning radius
to Crafts Ave. This will reduce turning speeds
and improve driver and pedestrian expectancy.
City staff noted that the City has explored the possibility of closing Crackerbarrell Alley to vehicular traffic,
converting it to a pedestrian access to the rear parking lot. Given that the existing parking lot is also served
by driveways on Masonic Street immediately north of the intersection, this closure would reduce conflicts
between vehicles and pedestrians while having minimal impact on vehicular access to the parking lot.
Closing Crackerbarrell Alley would allow the crosswalk in front of City Hall to be relocated from its current
angled position to a more direct alignment improving visibility and decreasing the crossing distance. City
staff also noted that the sidewalk on Main Street adjacent to Crackerbarrell Alley is a pinch point. The
City should consider widening the sidewalk along this segment in order to match sidewalks along the rest
of the corridor.
Members of the team also noted that the
angle parking spaces adjacent to both
crosswalks across Main Street limit sight
distance for pedestrians. At the crosswalk
across Main Street, the handicap accessible
parking space on the north side west of the
crosswalk requires drivers to back into the
crosswalk in order to exit the space. The City
should remove four angle parking spaces and
relocate the handicap accessible space in
order to improve sight distance and prevent
drivers from backing into the crosswalk. As a
long term measure, the City should consider
constructing curb extensions at both
crosswalks, which may create an opportunity for a pocket park. In the short term, it may be necessary to
Figure 7 - Parked cars block sight distance for pedestrians at
Crafts Avenue.
Figure 8 - Parked cars block sight distance to a midblock crosswalk.
15| Northampton Walk/Bike Assessments | Final Draft
provide temporary curb extensions using flex posts to prevent short-term parking from occurring in the
clear zones adjacent to the crosswalks. Curb extensions may include bike parking within the area formerly
occupied by the angle parking spaces adjacent to the crosswalk, however care should be taken to ensure
that proper sight lines are maintained for pedestrians.
Short Term Recommendations
Remove the two parking spaces and relocate sidewalk furniture in front of City Hall in order to
improve sight distance to the crosswalk across Main Street and to the crosswalk across Crafts Ave.
Remove the angle parking space east of Crackerbarrell Alley to improve sight distance to the
crosswalk across Main Street.
Remove the angle parking spaces on both sides of Main Street within 20 feet of the crosswalk east
of Old South Street to improve sight distance to the crosswalk and prevent drivers from backing
into the crosswalk.
Provide temporary curb extensions using paint and flex posts.
Long Term Recommendations
Reconstruct Main Street to provide curb geometry on the south side of the roadway that matches
the curvature of the roadway, reduces corner radii, widens sidewalks adjacent to Crackerbarrell
Alley, and provides curb extensions at the two crosswalks across Main Street.
Install bike parking within the new curb extensions.
Close Crackerbarrell Alley to vehicular traffic to reduce conflicts with pedestrians on the sidewalk
and allow the realignment of the crosswalk in front of City Hall.
Intersection: Main Street at Pleasant Street/King Street
Existing Conditions
The intersection of Main Street at Pleasant Street/King Street is a large signalized intersection with three
to four travel lanes provided on each approach, including exclusive left turn lanes on all four approaches.
The traffic signal provides protected plus permitted left turn phasing on the northbound, southbound,
and eastbound approaches plus an exclusive pedestrian phase. City staff noted that there is an ongoing
project under design to modify the traffic signal to provide protected plus permitted left turn phasing on
the westbound approach.
Crash data indicate that there was one pedestrian involved crash at the intersection during the period
studied which did not result in an injury. There were five bicycle involved crashes reported at the
intersection four of which resulted in injury and one of which resulted in a fatality. The fatal crash involved
a left turning vehicle which failed to yield to an oncoming bicyclist.
16| Northampton Walk/Bike Assessments | Final Draft
Observations and Recommendations
Members of the team noted that due to the
large size of the intersection and the complex
signal phasing, pedestrians typically comply
with the traffic signals and cross during the
exclusive pedestrian phase. Many pedestrians
were observed crossing the intersection
diagonally during the pedestrian phase. The
City should consider installing continuous
corner ramps to allow for diagonal crossing
and updating the signal timing to provide
appropriate clearance for the diagonal
crossing. Members of the team suggested that
the intersection may be reconstructed as a
raised table intersection, allowing for
pedestrian crossing in all directions during the pedestrian phase.
Members of the team observed that the existing pedestrian push buttons do not provide accessible
pedestrian signal (APS) control and that the pedestrian signals do not include countdown timers. The City
should consider upgrading the signals to provide APS equipment and countdown indications. As part of
the ongoing project to install a protected plus permitted left turn phase for the westbound approach, the
City should also consider installing flashing yellow arrow indications on all four approaches to remind
drivers to yield to through vehicles and bicycles during the through phase.
The existing intersection does not provide any bike facilities consistent with the entire existing corridor.
The City should consider installing protected intersection treatments as part of a project to provide
separated bike lanes along the Main Street corridor as recommended above. Given the large size of the
existing intersection, it would likely be feasible to provide separated bike lanes and protected intersection
geometry, especially if complementary facilities are also provided in the future on Pleasant Street and/or
King Street. The protected intersection treatments would provide improved separation between vehicles,
pedestrians, and cyclists and reduce the incidences of crashes between turning vehicles and cyclists.
Short Term Recommendations
Install full radius corner ramps to allow for diagonal pedestrian crossing.
Update signal clearance times to allow for diagonal pedestrian crossing.
Upgrade the signal to provide APS equipment and pedestrian countdown indications.
Upgrade the signal to provide flashing yellow arrow indications.
Figure 9 - Pedestrians cross during the exclusive pedestrian phase.
17| Northampton Walk/Bike Assessments | Final Draft
Long Term Recommendations
Reconstruct the intersection to provide a raised table and/or protected intersection to improve
access and crossing for both pedestrians and bicyclists.

Accessible Pedestrian
Signals
Accessible pedestrian signals systems are
the components used at a signalized
intersection to alert pedestrians when
they may cross a roadway. Accessible
pedestrian signals may include audible
and vibrating features to assist visually-
impaired pedestrians.
Crosswalk
Crosswalks indicate to pedestrians the
appropriate place to cross the street and
inform drivers of potential pedestrian
movements in the street.
Curb Ramp and
Detectable Warning
Panels
ADA-compliant curb ramps provide
ramped access and detectable warning
for persons with disabilities. Curb ramps
are typically at least 5 feet wide with a
level landing pad. Detectable warning
panels should be a contrasting color to
the adjacent surface.
Curb Extensions
A curb extension is an extension of the
sidewalk at intersections or mid-block to
reduce the pedestrian crossing distance
and provide greater visibility for
pedestrians waiting to cross a street.
Curb Radii
Modifications to curb lines or edges of
the pavement at an intersection. These
modifications typically are used to
decrease crossing distances for
pedestrians or to reduce vehicular speed
by tightening the turning radii at the
intersection corners.
Appendix B | Northampton Walk/Bike Assessment | Final Draft
Facility Type Description Sample Photo
Edge Lines
Edge lines are solid white lines painted
along the roadside curb that defines the
driving lane and visually narrows the
travel lane. In some cases, edge lanes
may be used to create bicycle lanes.
In-Street Pedestrian
Crossing Sign
A removable high-visibility sign placed on
the centerline of a street prior to a
crosswalk to alert motorists to yield
when pedestrians are present in the
crosswalk.
Leading Pedestrian
Interval
A pedestrian crossing indication that
permits pedestrians to move into the
intersection 3-7 seconds before a green
light is given to turning motorists that
may cross the crosswalk.
Parklet
Permanent or temporary gathering area
installed in the street adjacent to the
curb as an extension of sidewalk space.
Pedestrian Hybrid
Beacon
An overhead flashing beacon activated
by pedestrians. The flashing lights alert
motorists to yield and increase visibility

Background
As a prerequisite to meeting funding criteria under the Federal Highway Administration’s (FHWA) Local
and Rural Road Safety Program, a Road Safety Audit (RSA) was conducted for the approximately half-
mile segment of Main Street/Bridge Street in Northampton, Massachusetts extending from Elm Street and
West Street on the west to Market Street and Hawley Street on the east. Main Street/Bridge Street is the
main east-west running thoroughfare providing pedestrian, bicycle, bus, freight, and vehicular access
through Downtown Northampton. During the years analyzed (2015 – 2017), 167 crashes occurred along
the corridor. During the RSA, members of the audit team discussed safety issues on a corridor -wide and
intersection-by-intersection basis.
A RSA is an important part of the Highway Safety Improvement Program (HSIP). A RSA is
required for HSIP funding applications, and if all or part of the proposed project is HSIP-eligible,
as RSA is required for 25% design plans. Within the study area limits, the intersection of Main
Street at King Street/Pleasant Street is part of the 2014-2016 HSIP crash cluster. This report
documents the findings of the RSA and is intended to be used by planners, engineers, and local
stakeholders to inform future design modifications. Knowing the success of an RSA, the MassDOT
Safety Management Unit is encouraging MassDOT Districts and communities to conduct RSAs at
the initial stage of the design process so as to help guide the design and reduce fatalities and injury
crashes for locations in which safety has been noted to be a factor in determining needs for
improvement. All future projects to follow from RSAs should implement the latest MassDOT,
FHWA, ADA, MUTCD & City design, traffic signal, and material standards/ guidance (for
example, a new MassDOT Engineering Directive, E-20-001 dated 1/2/2020 regarding
“Controlling Criteria and Design Justification Process for MassDOT Highway Division Projects”).
Project Data
Toole Design Group (Toole Design) facilitated the RSA on Thursday, November 21st, 2019. The audit was
held at the Northampton City Council Chambers in Northampton, MA beginning at 8:00 a.m. and concluded
at 3:30 p.m. Attendants of the RSA (shown in Table 1 below) included local and state stakeholders including
representatives from the Northampton Police Department, Northampton Fire Department, various
Northampton City departments, Pioneer Valley Planning Commission (PVPC), District 2 of the
Massachusetts Department of Transportation (MassDOT), MassDOT Traffic and Safety Engineering
Section, and other advocacy and education groups.

Prior to meeting, audit team members received a packet containing an agenda, crash details, and RSA
Prompt List. The agenda and additional meeting materials are provided in Appendices A and B,
respectively. Audit team members were asked to review the materials and visit the Main Street/Bridge
Street corridor prior to the audit.
The crash data analyzed for the RSA included 167 crashes occurring over a three-year period between 2015
and 2017. Of the 167 crashes, there were 37 non-fatal injury crashes (22%), with the rest being non-injury
crashes. Crash reports showed that the most common crash type was angle crashes, with 49 angle crashes
(29%) occurring during the study period. However, a similar number of single vehicle (45, 27%) and rear-
end crashes (43, 26%) were reported. In the single vehicle category, 12 crashes involved a parked vehicle
(27%), 11 crashes involved a pedestrian (24%), 11 crashes involved the railroad bridges (24%), 7 crashes
involved a fixed object (16%), and 4 crashes involved bicyclists (9%). Lastly, there were 30 reported side-
swipe crashes (18%).
Patterns in crash manner and locations guided the RSA discussion and form the basis for the organization
of this document. Table 2 and the list below describes the high-frequency crash locations. In addition to

Project Location Description
The RSA was conducted for the Main Street/Bridge Street corridor in Northampton, MA for the
approximately half-mile segment extending from Elm Street and West Street on the west to Market Street
and Hawley Street on the east (Figure 1). Main Street transitions to Bridge Street east of the Railroad Bridge,
located just west of Market Street and Hawley Street. The corridor, Route 9, is classified as a Principal
Arterial. The corridor is the primary east-west running thoroughfare providing pedestrian, bicycle, bus,
freight, and vehicle transportation across Downtown Northampton. Main Street/Bridge Street is a wide two-
way roadway, divided by either a double solid yellow line or a median (indicating no passing allowed). The
roadway functions as two lanes in each direction but is often unclear as there are no existing lane markings
provided aside from the centerline. The roadway width ranges from 62-92 feet (ft). The speed limits
throughout the half-mile corridor is posted as 25 mph.

Final Report
Figure 1: Route 9 study corridor
There are concrete sidewalks provided on both sides of the corridor lined with a brick and landscaped buffer
along the majority of the study area. Curb ramps are generally provided along the corridor; however ADA-
compliance is not provided throughout the corridor. Excessive ramp slopes and cross slopes as well as
missing detectible warning panels were noted at many locations. The corridor has several crosswalks that
are located at midblock and at intersections which are unsignalized. There are no dedicated bicycle facilities
along the majority of the corridor. An existing bicycle lane terminates at the western limit of the corridor
at Main Street and State Street. New South Street also has an existing northbound-only bicycle lane that
terminates 500 ft before the intersection of Main Street and New South Street. Additionally, there is an
existing sidewalk-level separated bike lane along a short segment of Pleasant Street south of Main Street.
ValleyBike bikeshare stations are located within the sidewalk on the northwest corner of the intersection of
Main Street at King Street and Pleasant Street, on the sidewalk under the railroad bridge, and at Pulaski
Park just off of Main Street near New South Street. Just south of the railroad bridges, at Union Station, the
New Haven and Northampton Canal Trail connects with the the Manhan Rail Trail in Easthampton and
eventually leads to New Haven. The MassCentral Rail Trail runs from Union Station north, crossing a bike
path bridge across Main Street, adjacent to the railroad bridge, and then extends east to Hadley and Amherst,
and west to Florence, Leeds, and Haydenville.
The Pioneer Valley Transit Authority (PVTA) operates bus service with six different routes (39/39E, B43,
R41, R42, R44, B48), and the Franklin Regional Transit Authority (FRTA) runs one route (Rt 31) within

the corridor These routes provide access between Smith College and Mount Holyoke College, Florence and
Downtown Northampton, Hadley and Northampton, Williamsburg and Northampton, Northampton and
Hampshire Mall/Plaza, and Greenfield to Northampton. The bus stop in front of Pulaski Park and the
Academy of Music is a major stop for the majority of the routes, and functions as the city’s primary pulse
point (for PVTA and FRTA routes). Peter Pan buses stop at the nearby Peter Pan bus terminal at the bottom
of Crafts Avenue and utilize a portion of the corridor. Bus stops along the corridor are indicated with a
street post with inconsistent signage and other transit amenities. The Northampton Courthouse and the
Pulaski Park pulse point are the only stops with bus shelters within the study area. The corridor is also
connected to the Northampton Amtrak station, located south of the railroad bridges between Strong Avenue
and Hawley Street.
The corridor has on-street front-in angled parking as well as parallel parking throughout the roadway as
well as side streets. Conflicts with parked vehicles backing out and general difficulty navigating and finding
parking spaces was noted.
The entire half-mile stretches of roadway with intersecting streets, which are all owned and maintained by
the City of Northampton, was discussed during the RSA.
Specific descriptions of the intersections within the study area are provided below.

Main Street at Elm Street/West Street and State
Street/New South Street
These two signalized intersections (see Figure 2)
are located at the westernmost end of the RSA
study area. Main Street transitions to Elm Street at
the intersection with West Street and runs in the
general east-west direction. West Street, an Urban
Minor Arterial, and New South Street, an Urban
Principal Arterial, intersects Main Street from the
southwest and southeast, respectively. State Street
is classified as an Urban Minor Arterial and is a
two-way roadway consisting of one lane in each
direction that meets Main Street from the north.
The Elm Street eastbound approach has two marked travel lanes with one through lane and one shared
through/right-turn lane. The westbound approach has one left-turn only lane onto West Street and a
through travel lane to Elm Street. The West Street northbound approach consists of one left-turn only lane
and one right-turn lane for traffic proceeding eastbound to Main Street.

Audit Observations and Safety Enhancements
During the RSA, the audit team identified safety issues and discussed potential safety enhancements to
address the issues on both a corridor-wide and intersection-by-intersection basis. Each safety issue and
associated enhancement are described below for each location.
Corridor-Wide
Roadway Geometry
Observations
The wide geometry of the roadway was a common topic of
discussion among RSA Members. The RSA team noted
that the wide roadway contributes to irregular traffic
patterns for motorists and long crossings for pedestrians
(see Figure 11). The Main Street corridor typically ranges
from 62 to 92 feet in width. The corridor operates as a two-
way, two-lane roadway with only a double centerline
provided, which causes confusion and discomfort for
many, especially those who are unfamiliar with the area.
The lack of lane delineation within the wide roadway as
well as the overall geometry also contributes to vehicle
weaving, last-minute position changes, vehicle turning
movement issues, and pedestrian safety issues. As a result,
a significant number of crashes along the corridor were
side-swipe (18.5%) and angle (27.5%) crashes. However,
RSA members also noted that the confusion associated
with lack of defined lanes may help to slow down traffic
as drivers are more cautious navigating the roadway.
Sightline issues on the side street connections with Main Street were cited as a contributing factor to unsafe
conditions, queuing in crosswalks, and congestion on Main Street. Specific sight line restriction locations
are discussed further under the appropriate intersection section below. Snow clearance and storage along
the corridor were also discussed as a factor that contributes to low visibility, as snow is currently piled in
the center of roadway during snow events. Furthermore, audit members discussed the general feeling of
chaos and overstimulation throughout the corridor.
Potential safety enhancements
• Evaluate the feasibility of narrowing the roadway corridor and reallocate available space for
vulnerable users to increase safety and accessibility.
• Evaluate the need for existing turn lanes and the feasibility of providing additional designated turn
lanes.
• Evaluate the number and mix of travel lanes needed for the corridor and stripe travel lanes
accordingly
Figure 11: Pedestrian crossing on the wide
intersection of Main Street at State Street and
New South Street
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
• Evaluate the feasibility of curb extensions at intersections to increase sight lines from the minor
approaches and increase safety for pedestrians. Consideration should be given to the potential
interference with bicycle lanes.
• Evaluate the feasibility of installing RRFBs or other crossing enhancement signage to improve
crosswalk visibility.
• Evaluate the installation of medians (raised or flushed) along the Main Street approaches.
Pavement Markings and Conditions
Observations
Many sections of the corridor were noted to have missing or
fading pavement markings (see Figure 12). Stop bars, lane lines,
lane designations markings, and crosswalks were all noted to be
missing or faded at numerous locations along the corridor. This
was discussed as a source of confusion for drivers and a safety
issue for pedestrian visibility.
Potential safety enhancements
• Reinstall missing or faded pavement markings to reduce
vehicular confusion and improve vehicular and
pedestrian safety. Consider updating the markings with
polyurea or recessed thermoplastic markings.
Signal
Equipment
Observations
Members of the audit team observed that the signal equipment
along the corridor was inconsistent, old, or outdated. At several
locations, the signal heads were misaligned with their
appropriate travel lane locations and were missing retro-
reflective backplates, which improve driver awareness and
visibility of traffic signals. Traffic signal locations vary
between side-mounted post signals or mast arm mounted.
Signals for all Main Street approaches along the corridor are
provided on mast arms. State Street, New South Street, Hawley
Street and Market Street signals are side-mounted signals
while King Street, Pleasant Street, Elm Street and West Street
have mast arm mounted signals. These inconsistencies and
missing safety countermeasures were noted as contributing

Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
Existing pedestrian signals do not have Flashing Don’t Walk countdown timers (see Figure 13) and
accessible pedestrian signals (APS) were missing at the vast majority of signalized crossings.
Potential safety enhancements
• Replace outdated and old signal equipment, where necessary.
• Evaluate signal head locations according to lane locations and relocate to appropriate locations to
increase signal visibility. Evaluate the need to upgrade all traffic signal infrastructure and assess
mast arm capacity.
• Install retroreflective backplates on signals to improve signal visibility.
• Update signal equipment with APS push buttons and pedestrian countdown timers for all signalized
intersections to increase safety for pedestrians.
• Evaluate the use of camera detection rather than loop detectors, some of which are not functioning.
Signal Timing and Phasing
Observations
The audit team discussed that inconsistent signal timing and phasing schematics lead to excessive delay for
all users. These long delays can also lead to unsafe behavior. For example, vehicle weaving, and red-light
running were discussed as a result of impatience caused by long wait times. RSA team members also noted
that there was no signal coordination present throughout the corridor.
Audit team members noted that the pedestrian phasing at intersections is inconsistent across the corridor.
There are some locations that provide exclusive pedestrian phasing, while others provide concurrent
pedestrian crossings. This inconsistency was noted to cause confusion and to potentially encourage
jaywalking. The crosswalk across New South Street was the only observed location equipped with LPIs.
Leading Pedestrian Intervals (LPIs) give the pedestrians an advanced start time to begin cros sing an
approach before the parallel street receives their green light. This allows pedestrians to establish themselves
within the crosswalk before traffic may advance and potentially turn across the pedestrian path of travel.
Audit team members also noted that flashing Don’t Walk times for pedestrians generally did not provide
adequate time for a pedestrian to safety cross the intersection. Furthermore, where exclusive pedestrian
signal phasing is provided, many pedestrians were observed to traverse the intersection diagonally. The
current crossing times within the signal do not account for the distance for a pedestrian to cross diagonally
and therefore do not provide adequate time.
Potential safety enhancements
• Evaluate signal re-timing and phasing at all signalized intersections to reduce delays.
• Consider signal coordination along the corridor, with the need for transit pre-emption where
appropriate.
• Evaluate the preferred pedestrian phasing for the corridor and provide consistent pedestrian phasing
throughout the corridor.
• Install pedestrian advance walk signals for any intersections that have concurrent vehicle/pedestrian
phases.
Page 18
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
• Consider implementing LPIs for all signalized crosswalks to increase pedestrian visibility and
safety.
• Evaluate duration of flashing “Don’t Walk” times.
Signage
Observations
Signage clutter, faded signs, and non-compliant signs were consistently brought up by audit members
throughout the corridor.
Potential safety enhancements
• Evaluate signage along the corridor and at study area intersections. Remove and replace all non-
compliant MUTCD signs. All new signs should confirm to current MUTCD standards.
• Remove unnecessary signage to reduce sign clutter and potential confusion.
Pedestrian Accommodations and
Crossings
Observations
A total of eleven crashes (6.6%) involved pedestrians at
unsignalized marked crosswalks throughout the corridor.
Audit members noted that long crossings (see Figure 14),
restricted sight lines, and low lighting were contributing
factors to pedestrian crashes at unsignalized crosswalks. The
excessive wait times for pedestrians throughout the corridor
were also discussed as contributing to impatience and
jaywalking at signalized crosswalks. As previously
mentioned, inconsistent pedestrian signal phasing (concurrent
or exclusive) throughout the corridor was noted as a source of
pedestrian confusion. Continental crosswaks are provided
throughout the corridor, however audit team members noted
that several crosswalks were faded. Curb ramps are generally
provided, however many were not ADA-compliant and were
missing tactile warning panels.
Figure 14: Pedestrian walking beyond the
long crosswalk lines on Main Street andWith the exception of the north side of West Street and the State Street west side of State Street just north of Main Street, sidewalks
are provided along both sides of all approaches within the study area. Sidewalks are generally constructed
of concrete with a brick buffer strip. The condition of sidewalks throughout the corridor was frequently
discussed by audit members. Heaving and c racking was observed as well as errant signposts and street
furniture that create tripping hazards. Some audit members also mentioned that since Main Street has many
restaurant and shops, seasonal sidewalk cafes narrow the sidewalks and force pedestrians to travel closer to
the edge of the roadway onto the brick buffer strip that may not meet ADA standards. The DPW issues
permits for tables and chairs while requiring that a minimum clear path of pedestrian travel be maintained.
The minimum clear path ranges from 5.5 to 9.0 feet is width, depending on the segment along Main Street.
Page 19
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
Limited lighting was also mentioned as a
cause of concern for pedestrian visibility,
particularly for the side street approaches.
Audit members mentioned that parking
spaces too close to crosswalks contributed
to the problem of limited sight lines as well
(See Figure 15). Additionally, overhead
lighting was observed above Main Street,
however lighting is not provided over the
minor street approach crosswalks. This may
have contributed to the four (36.3%) of the
eleven crashes involving pedestrians on a
crosswalk took place at night.
Figure 15: Parking space too close to crosswalk
Potential safety enhancements
• Consider widening sidewalks using reinforced concrete materials to narrow the roadway, provide
more pedestrian space, and accommodate sidewalk cafes without sacrificing pedestrian clearances.
• Consider implementing curb extensions and/or pedestrian refuge islands to shorten crossing
distances and increase pedestrian safety while being cognizant of potential interference with bicycle
lanes and snowplow operations.
• Consider installing enhanced visibility crossing signs and pavement markings. Evaluate specific
locations for High-Intensity Activated CrossWalk (HAWK) beacon or Rectangular Rapid Flashing
Beacon (RRFB) applications.
• Consider replacing bricks in the buffer spaces next to the sidewalk with smoother, ADA-compliant
surface treatment including consideration for design to enhance infiltration from surface drainage
(such as porous pavement, rain gardens, etc.).
• Evaluate lighting along the corridor and above minor street approaches and install or replace where
necessary to improve visibility and safety in low-light conditions.
• Reinstall crosswalks with high visibility thermoplastic crosswalks to increase visibility.
• Evaluate and upgrade all ramps, pedestrian signals, and sidewalks to be ADA-compliant.
• Evaluate the location of existing crosswalks and if they should be moved to more visible locations.
• Evaluate feasibility of raised crossings on Main Street and side streets to slow vehicular traffic at
key crosswalks. Coordination with the Police and Fire Departments should be considered.
• Evaluate installation of gore markings to prevent parked vehicles within 20 feet on each side of a
crosswalk.

Final Report
Bicycle Accommodations
Observations
Bicycle accommodations are not provided along the
corridor, with the exception of conventional bike lanes that
terminate at the westernmost end of the corridor at Main
Street and State Street. New South Street also has an
existing northbound-only bicycle lane that terminates 500
ft before the intersection of Main Street and New South
Street. Additionally, there is an existing sidewalk-level
separated bike lane on a short segment of Pleasant Street
south of Main Street. A ValleyBike bikeshare station is
located within the sidewalk on the northwest corner of the
intersection of Main Street at King Street and Pleasant
Street (See Figure 16) and under the railroad bridges on
the south side of Main Street and Bridge Street. Just south
of the railroad bridge, at Union Station, the New Haven
and Northampton Canal Trail connects with the Manhan
Rail Trail in Easthampton and eventually leads to New
Haven. The MassCentral Rail Trail runs from Union
Station north, crossing a bike path bridge across Main
Street, adjacent to the railroad bridge, and then extends
east to Hadley and Amherst, and west to Florence, Leeds,
and Haydenville. Regarding biking in the corridor itself,
some members noted that this corridor was listed in the
MassDOT Bicycle Transportation Plan as having “100% Potential for Everyday Biking” as it connects to
many existing trails (Figure 17). . The variety and volume of bicycle parking throughout the corridor was
described as inadequate by RSA members. During the audit, members also observed multiple bicyclists
traversing intersections during exclusive pedestrian phases.
Four crashes (2.4%) reported for the corridor involved a bicyclist. With no designated space for bicyclists
within the roadway, sidewalk biking is a common behavior even though it is illegal according to City of
Northampton ordinance. In some instances, contraflow biking was also noted. While Valley-Bike bikeshare
locations are provided along the corridor, RSA members discussed that some stations are placed within the
sidewalk and limit space for pedestrians. This can pose a safety hazard for pedestrians with accessibility
needs and cause queuing at sidewalks. Audit members recommended that while this audit references crash
data from 2015-2017, it would be a worthwhile task to go beyond to see if any bicyclist fatalities existed in
the corridor. In 2012, one bicyclist fatality was identified in the intersection of Main Street and Pleasant
Street, in which the bicyclist was struck by a vehicle making a left turn from Main Street to Pleasant Street.
Potential safety enhancements
• Evaluate the feasibility of providing separated or protected bicycle accommodations throughout the
corridor connecting to existing facilities.
Figure 16: ValleyBike bike share location and
wayfinding map

Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
• Consider installing high-friction surface treatment for bike lanes especially at intersections, high-
volume driveways or areas where traffic is merging to another lane and crossing the bike lane.
• Consider dedicated pavement markings for bicycles turning left from bicycle lanes including two-
stage turn queue boxes at intersections.
• Add enhancements along the corridor, including MUTCD-compliant signage and wayfinding, to
provide better Rail Trail connections
• Assess bicycle parking locations, styles, and supply. Consider additional bicycle parking options
including corrals, bicycle storage boxes, bike racks, etc.
• Evaluate bikeshare locations to maximize pedestrian space and improve access to bicycles.

Transit Accommodations
Observations
Audit members remarked that there are many bus stops along the corridor that may not be optimally located
or sited for demand. Additionally, there were observed instances of backups and queuing due to transfers
in bus driver shifts and layover time. Buses were sometimes noted to block crosswalks due to lack of queue
space. The locations of the bus stops being sub-optimal and issues with coordination with the Amtrak
station may be contributing to more queuing and confusing traffic operations.
Potential safety enhancements
• Coordinate with PVTA, FRTA, and other relevant stakeholders to evaluate bus stop locations
corridor wide. Consideration should be given to coordination schedules of bus operations with the
Amtrak station.
• Discuss upgrading transit facilities with all transit authorities’ needs (such as concrete pads,
shelters, benches with compatible seating, real-time electrical connections, bike racks, etc.).
Parking and Loading
Observations
Dedicated loading zones are not provided
throughout the corridor and contribute to
curbside challenges for commercial
loading and unloading. Furthermore, truck
loading and unloading is generally
unavailable behind Main Street buildings.
As a result, trucks use the center of
roadway to load and unload (See Figure
18). Audit team members noted that
majority of the commercial loading occurs
during peak traffic times. Trucks were also
noted to parallel park behind the angled
parking, which blocks in vehicles using the
angled parking and limits visibility for
vehicles backing out of angled parking.
Figure 18: Trucks observed to be loading/unloading in the
middle of roadway
Police and the City Parking Enforcement Administrator also noted that enforcement of the road can be
challenging because of parking patterns in the area, which leave the police with few options for parking.
With the rise of rideshare services, pick up and drop off activity has increased in the area, however no taxi
or rideshare zones or curb control are provided, which contribute to double parking, and standing at fire
hydrants and in wheelchair accessible parking spaces. Specific locations where double parking was
observed include spots near banks and the Starbucks at 211 Main Street. The City recently upgraded to a
pay-by-plate parking policy, which has been useful for conducting utilization and turnover analysis.
Front-in angled parking and parallel parking spaces are provided throughout the study area. Many safety
challenges are associated with head-in angled parking including low visibility when backing and qui ck

movements, including U-turns, by vehicles to turn into open spots. These challenges are illustrated in the
crash reports where 13 (7.8%) of total crashes involving vehicles backing out of the head-in spots. The City
noted that a short period trial to test out converting the head-in parking to back-in parking was conducted
in recent years, however, the trial was done only along a small segment of the corridor and was not clearly
communicated. As a result, the trial was poorly received.
Parking stall widths and angles are inconsistent
throughout the corridor. In addition, multiple
parking spaces were located within 10 feet of a
hydrant, which is against state law (See Figure
19). On-street parking was also noted to be
located too close to crosswalks, which restricts
visibility between motorists and pedestrians
within the crosswalk. While there were some
ADA parking spaces, audit members
mentioned that the utilization of the spaces may
need to be evaluated. Residents and retailers
have the perception that parking along the
corridor is limited, however the lack of
wayfinding to parking garages is contributing
to this perceived notion.
Potential safety enhancements
• Evaluate the feasibility of designating loading zones, specified loading times, and shared ride curb
control.
• Restrict parking within appropriate distances of all fire hydrants and crosswalks to improve safety
and accessibility to the hydrants and crosswalks.
• Evaluate alternate parking schemes including removal of parking, reverse-angle parking, parallel
parking etc.
• Restripe parking to provide consistent parking stall widths and angles or lengths.
• Provide adequate daylighting for on-street parking from all crosswalks based on sight distance
requirements.
• Evaluate the number of ADA parking spaces along the corridor to ensure demand is met.
• Evaluate parking and loading spaces for the police, taxi, shuttle, and ride share services.
• Coordinate with business district to modify parking spaces.
• Install parking garage wayfinding signage.
Freight Accommodations
Observations
Audit members noted that a large volume of heavy trucks pass through the corridor, as the corridor serves
as the main east-west access route from I-91.

Final Report
Potential safety enhancements
• Evaluate truck routes that provide access without taking away space from the corridor. Alternate
route options should be coordinated at the federal level. Care must be taken, however, to avoid
diverting vehicles that bring business to downtown.
Main Street at Elm Street/West Street and State Street/New South
Street
Roadway Geometry
Figure 20: Pedestrian crossing across the wide
intersection at Main Street and State Street
Observations
The entire intersection(s) was perceived by audit members
to be too expansive (See Figure 20). The wide roadway
and offset geometry complicate turning movements and
may have been a contributing factor in the reported 15
angle crashes (41.7%) out of the total 36 crashes at this
location. The Main Street eastbound approach consists of
two thru travel lanes, but only provides one wide receiving
lane without pavement markings or signage, forcing
vehicles to merge within the intersection and potentially
contributing to the five reported side-swipe crashes
(13.9%) at this location.
This intersection is downhill in the eastbound direction,
which encourages high speeds from drivers and bicyclists,
specifically eastbound from Elm Street to Main Street.
One reported crash at this location involved an eastbound
bicyclist attempting to turn right from Main Street onto
New South Street, for which speed was listed as a
contributing factor. In general, this intersection was noted
to have many congestion-related crashes, which may have
contributed to the 10 rear-end crashes (27.8%) at this
location. Additionally, New South Street and State Street
have offset geometry that was noted to be a cause of confusion.
There is a driveway that intersects Main Street from the south between West Street and New South Street.
The driveway intersects Main Street at a location where Main Street also has a dedicated right turn lane,
bike lane, two through lanes, and a dedicated left turn lane for the eastbound approach at New South Street
and State Street. During the audit, multiple vehicles were observed making a left turn from the driveway
onto Elm Street, causing them to travel in opposing traffic. Additionally, some vehicles were also observed
making a left lane U-turn from Main Street into the driveway causing conflicts with West Street right
turning vehicles.
Page 25
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
Potential safety enhancements
• Evaluate the feasibility of a roundabout or a peanut-about treatment to better accommodate traffic
demands and deter speeding.
• Evaluate options that tighten the intersection box to reduce crosswalk and vehicle distances
crossing the intersection.
• Confirm that the number of feeding lanes match the receiving lanes to avoid merging problems.
• Extend the median on Main St, between West Street and State Street, to prohibit vehicles from
turning left out of the residential driveway.
• Consider prohibiting U-turns for the Main Street westbound approach, forcing users of the
driveway to take a safer left turn onto New South St to utilize the alternate entrance.
• Consider the required geometry to accommodate large tractor trailer trucks on these numbered state
routes.
Pavement Markings and Conditions
Observations
The audit team discussed missing and faded pavement
markings at this intersection. In particular, no advanced
warning lane designations along West Street and State Street
are provided. The lack of advance warning markings on West
Street was noted to contribute to eastbound vehicles
attempting to turn left onto State Street and queuing within the
dedicated left-turn lane intended for vehicles turning
westbound onto Elm Street. With vehicles attempting to turn
left onto State Street after turning right from the left-turn lane
on West Street, conflicts with merging becomes an issue with
existing eastbound vehicles turning left onto State Street.
Additionally, westbound vehicles on Main Street were
unaware that there is a left-turn only lane on the approach to
New South Street since markings are faded. As a result, people
attempt to switch lanes at the last moment. This confusion may
be a contributing factor for the 5 (13.9%) of same direction
sideswipe crashes out of the total 36 crashes at this location. Figure 21: Bicycle turning queue boxes at
Main Street on eastbound State Street are
not painted green Audit team members also noted that the New South Street stop
bar was set back, limiting available sight lines and visibility primarily for the right-turning vehicles.
Furthermore, the Main Street eastbound bicycle turning queue boxes at State Street were not painted green
and were too wide spanning several travel lanes (See Figure 21).
Potential safety enhancements
• Install advanced lane designation markings where appropriate to reduce driver confusion.
• Implement lane tracking pavement markings for West Street left and right turn movements.
• Evaluate and relocate the New South Street stop bar location to maximize sight lines.
• Evaluate narrowing the size of the stop bar/box at Main/State/New South to reduce crossing
distances for vehicles and pedestrians.
Page 26
Road Safety Audit—Route 9, Northampton, MA

Final Report
• Reinstall the Main Street bicycle queue box with appropriate green paint and continue bicycle lane
broken white line through intersection.

South Street showing green arrow for right-
turning vehicles
Signal Equipment
Observations
Signal heads are provided overhead on mast arms for the
Main Street, Elm Street, and West Street approaches
while the State Street and New South Street approaches
have post mounted signal heads. The audit team noted
several instances of signal equipment related
inconsistencies. Audit team members discussed that the
Main Street eastbound right-turn green signal at New
South Street should have a green ball or the existing
green arrow. Currently, the signal includes a green
through arrow as well as a green right turn arrow. The
eastbound right-turns operate protected/permissive,
being allowed to proceed with the through traffic. Team
members noted that the green arrow should be changed
to a green ball for this reason and that right-turning
vehicles are to yield to the pedestrians crossing New
South Street during the permissive part of their phase
(See Figure 22). Additionally, the Elm Street westbound
signal at West Street has one overhead signal serving
both through and left-turn lane, with an additional post
mounted signal with flashing beacons that activate when
the pedestrian phase across West Street is active. It was
noted that this sign is active during inappropriate times of the signal cycle. When vehicles have a green left
arrow, that movement should be protected, and the beacons should not be flashing during this time. Other
inconsistencies include the pedestrian head crossing in the southwest corner which was noted to be mounted
too low, Main Street westbound approach to State Street, which has a four-section signal head with a yellow
ball not used, and the out of service “no right on red” box on the mast arm on Main Street eastbound
approach west of New South Street. 8 (22.2%) out of the total 36 crashes at this location involved a vehicle
heading eastbound and another vehicle making a westbound left-turn movement, a pattern that was brought
up by some to be due to confusion with signal equipment
In the Main Street westbound direction, the glare from the sun was noted to restrict visibility of the signal
heads, particularly the left-turn signal head, at West Street. One of the reported angle crashes at this location
involved this westbound left-turning movement, for which sun glare was noted as the contributing factor.
Potential safety enhancements
• Evaluate the effectiveness and safety of green right-turn arrow versus the green ball options to
reduce driver confusion.
Page 27
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
• Evaluate Main Street westbound signal head at West St to reduce conflicts with West Street
crosswalk and westbound left turn movements
• Evaluate pedestrian head crossing height to meet MUTCD standards and install pedestrian
countdown timers and APS at all existing crosswalks.
• Evaluate Main Street westbound signal head at State Street. Replace yellow ball if necessary or
replace signal head with three-section signal head, as appropriate.
• Evaluate the feasibility of making eastbound Main Street at New South Street a “no right on red”
and swap out the red/yellow balls with red/yellow right arrows.
• Replace the Main Street eastbound green arrow with a green ball.
Signal Timing and Phasing
Observations
Signal timing and phasing was described by audit members as inefficient in meeting the needs of existing
traffic demands. The intersection of Main Street at Elm Street and West Street operates on a three-phase
cycle: Main Street westbound with Elm Street eastbound; West Street; Main Street westbound and West
Street right-turns. The intersection of Main Street at State Street and New South Street operates on a five-
phase cycle: protected left-turns for the State southbound and Main Street eastbound and westbound
approaches with the concurrent diagonal pedestrian crosswalk; Main Street through movement; New South
Street and Main Street eastbound right-turns; State Street and Main Street westbound right-turns. Both
signal phasing sequences provide concurrent pedestrian phasing.
The Main Street westbound left-turn to New South Street was noted to have an unnecessarily long signal
phase, creating delays for the other movements. In addition, the State Street southbound phase was noted
to be too short, only allowing for approximately three vehicles to clear the intersection . Inadequate signal
timing can cause driver frustration and yellow or red-light running. This may have contributed to the 10
(27.8%) reported rear-end crashes out of the total 36 crashes at this location.
Potential safety enhancements
• Evaluate signal timing and phasing to allow for efficient and safe flow of traffic based on existing
demands of all users.
• Address the length of the full signal cycle that leads to excessively aggressive pedestrian and
vehicle movements (e.g., jaywalking, continuing through intersections into the red cycle).
• Evaluate if concurrent crosswalk phasing is adequate for safety with turning volumes at the
intersection

Final Report
Figure 23: "No turn on red" sign blocked by a pole
and "Right turn must turn right" sign at Main
Street westbound approach to State Street
Signage
Observations
Missing, faded, and inconsistent signage was brought
up by audit members at this location. There was a “Stop
for Pedestrians When Turning” sign within an outdated
message box on the Main Street eastbound mast arm at
New South Street. Audit team members noted that the
West Street median had a “Keep Right” sign and “Left
turn must turn left” sign stacked, which may cause
confusion for drivers.
Sign clutter was noted corridor-wide, however
particularly in this location. An existing “No turn on
red” sign for the Main Street eastbound approach at
State Street was observed to be blocked by a pole and
“Right turn must turn right” sign (See Figure 23).
Additionally, there were many non MUTCD compliant
signs including the “Left Turners Yield on Green
Light” and the “Left Turn Yield to Pedestrians and
Vehicles When Flashing” for vehicles at westbound
approach of Main Street and West Street
There is no lane assignment signage for the West Street
approach and Main Street eastbound approach at State
Street. Main Street eastbound vehicles queueing to turn left onto State Street were noted to be queued back
within the West Street left-turn lane, intended for vehicles turning left to go westbound on Elm Street. The
vehicles attempting to turn left onto State Street from the left-turn lane on West Street creates a conflict
with eastbound vehicles attempting to turn left onto State Street that have to merge into the left lane at the
appropriate time. As a result, people attempt to switch lanes in the last minute. This confusion may be a
contributing factor to the 5 (13.9%) same direction sideswipe crashes out of the total 36 crashes at this
location. Furthermore, as mentioned earlier, many westbound vehicles were observed making a U-turn into
the driveway causing conflict with eastbound traffic.
Potential safety enhancements
• Remove unnecessary signage and to reduce sign clutter and potential confusion. Ensure all signs
are MUTCD compliant.
• Install lane assignment signage to reduce driver confusion.
• Evaluate if the outdated box that historically displayed the message “No Turn on Red” should be
reactivated/reinstalled/removed from the traffic signal.
• Evaluate appropriate placement of signs to reduce confusion and improve visibility.
• Install a “No U-Turn” sign for westbound Main Street at West Street to prevent dangerous U-turns
into the driveway.

Final Report
Pedestrian Accommodations and Crossings
Observations
Audit members noted that Smith College building
locations along the Elm Street approach generated high
pedestrian traffic along the sidewalks and jaywalking
across Elm Street. There is currently no crosswalk across
Elm Street east of Bedford Terrace. Audit members
discussed providing a midblock crosswalk across Elm
Street or across Elm Street at the intersection of Main
Street. Additionally, a “goat path” was observed on the
west corner of Elm Street at West Street, indicating a clear
desire line from the sidewalk terminus to the on-street
parallel parking provided along the north side of West
Street (See Figure 24). There is currently no sidewalk
provided along the north side of West Street outside of the
intersection corner.
Continental-style crosswalks are provided across the West
Street, New South Street, State Street, and Main Street
westbound approaches. Medians on the West Street and
New South Street approaches provide pedestrian crossing
refuge but also make the crossing longer and less direct.
Audit members noted that the refuge islands are too narrow
and does not provide detectable warning panels within the
refuge as required by ADA standards.
A crosswalk is provided across Main Street from the southwest corner of New South Street and to the
northeast corner of State Street. Due to the geometry of the crosswalk, the crosswalk is an extremely long
crossing for pedestrians. Audit members noted that the signal phase for this crossing required excessive
time within the cycle to allow for adequate pedestrian crossing time. Audit members discussed relocating
the Main Street crossing to shorten the crossing and necessary time within the signal phase. The crosswalk
had been relocated for a short period before, but it was noted that pedestrians kept crossing in this direction
anyway.
Potential safety enhancements
• Evaluate feasibility of providing a designated crossing with appropriate safety enhancements across
Elm Street, either at West Street, Main Street or midblock.
• Evaluate feasibility of installing sidewalks from the west corner of Elm Street at West Street along
the north side of West Street to provide safe pedestrian accommodations to the on-street parking
along West Street.
• Evaluate the feasibility of relocating the diagonal Main Street crosswalk to provide a shorter and
safer crossing. Recommendations included: a crosswalk west of State Street or across Elm Street.
• Restripe the diagonal crosswalk with continental-style crosswalk markings (the standard for all
other downtown crosswalks).
Figure 24: "Goat path" observed on the corner
of Elm Street at West Street
Page 30
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
• Consider widening the median at West Street to provide an ADA-compliant pedestrian refuge with
detectable warning panels.
Bicycle Accommodations
Observations
The existing bicycle lanes on Elm Street terminate at State
Street (See Figure 25). A bicycle queue box is provided for
the Main Street eastbound approach at New South Street.
The bicycle queue box spreads over multiple lanes, which
makes it difficult for bicyclists to safely and comfortably
make turns. Audit team members noted that the queue box
was not painted green, but rather left empty with the white
bicycle symbols. Two reported crashes involving bicyclists
were reported at this location during the study period.
Audit team members also noted that the horizontal curve
along Elm Street and the position of the Elm Street median
force vehicles who are queued at the stop bar to block the
bicycle lane with the rear passenger-side corner of their
vehicles.
Potential safety enhancements
• Consider reinstalling queue box with green paint.
• Consider providing a two-stage turn box in front of
the crosswalk at the northbound West Street
approach to facilitate turns for less-experienced bicyclists.
• Consider realigning the Elm Street travel lanes and bicycle lane.
• Consider adding vertical delineation to help keep vehicles from encroaching on the bicycle lane.

Final Report
Main Street at Masonic Street
Roadway Geometry
Observations
The wide geometry at this intersection was cited as a challenge
for southbound vehicles turning left onto Main Street. When
turning left from Masonic Street onto Main Street, vehicles must
find a gap and navigate this wide turn against the wide travel
lanes (See Figure 26). Furthermore, audit members noted that
left-turning vehicles are typically focused on waiting for the
queued traffic to clear on Main Street and often overlook
pedestrians within the Main Street crosswalk. Five of the
reported crashes (33.3%) out of 15 total crashes at this
intersection involved a left-turning vehicle from Masonic Street.
Out of the five, three (60%) crashes involved a pedestrian within
the crosswalk. Some members of the audit team also noted that
since the closure of the Cracker Barrel Alley, Masonic Street
has seen more traffic as it is now the only access to the Masonic
parking lot from Main Street. Others noted, however, that
vehicles approaching from the east often use Center Street and
there are no traffic counts to support higher traffic on Masonic
between Main Street and the parking lot.
Potential safety enhancements
• Consider restricting left turns from Masonic Street to discourage the unsafe vehicular maneuvers.
• Consider installing a center median on Main Street to restrict this movement.
• Consider reducing the roadway width to decrease the number of lanes being crossed while making
left turns in and out of Masonic Street

Final Report
Page 33
Pavement Markings and Conditions
Observations
The audit team noted that queuing from the traffic signal at
State Street blocks the Masonic Street intersection. Queuing
related congestion may have contributed to the six reported
rear-end crashes (40%) out of the total of 15 crashes at this
intersection. Additionally, it was noted that there are no lane
markings on Main Street at this location which contributes to
difficulty exiting Masonic Street and as a result, can contribute
to conflicts with pedestrians and courtesy crashes for left-
turning vehicles.
It was also noted that although Masonic Street operates as
STOP-controlled, there is no stop bar or centerline on Masonic
Street (See Figure 27).
Potential safety enhancements
• Install “Don’t Block the Box” pavement markings and signage to ensure that the intersection is
clear from traffic queuing for vehicles to access and egress Masonic Street.
• Install stop bar on Masonic Street
• Consider installing a centerline on Masonic Street.
Signage
Observations
The Masonic Street southbound approach operates as stop-controlled, however audit members observed
that a stop sign was not present. Adding STOP sign can alleviate safety risks as an approaching vehicle
becomes aware that they are required to stop for the traffic on Main Street. The lack of appropriate signage
and STOP-control ordinance on this street may have contributed to the six (40%) rear-end crashes along
the Masonic Street approach.
Potential safety enhancements
• Install stop sign for Masonic Street southbound approach.
Pedestrian Accommodations and Crossings
Observations
Pulaski Park and a major transit stop is located across from the Masonic Street intersection. A continental
crosswalk is provided across the Main Street westbound approach at Masonic Street, located at the eastern
corner of the park. Though a crosswalk is present at one corner of the park, members of the audit noted
jaywalking from Pulaski Park to the north side o f Main Street. Audit members also noted that this
intersection experiences high pedestrian activity, specifically during a transit bus pick -up/drop-off time.
Pedestrians clustered at the bus stop may make it difficult for vehicles to determine whether they are just
waiting for the bus or if they intend to cross Main Street at the crosswalk. Crash reports show that four
Figure 27: Missing stop bar and centerline
on Masonic Street
Potential safety enhancements
• Consider whether the main transit pulse point at Pulaski Park should be relocated or lengthened
while minimizing crosswalk conflicts and if there are any Bus Rapid Transit light strategies that
could increase the speed of bus loading.
• Evaluate the bus lane at the Pulaski Park pulse point and determine if it needs to be lengthened
while minimize crosswalk conflicts to the east and the west.
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
(26.7%) out of the total of 15 crashes in this intersection involved a pedestrian at the Main Street crosswalk.
Additionally, outdoor cafes were mentioned to be popular in this area, occupying available sidewalk space
during spring, summer and fall. The outdoor cafes force pedestrians to travel closer to the edge of the
roadway.
Potential safety enhancements
• Consider installing a crosswalk across the Main Street eastbound approach or widening the existing
crosswalk to accommodate the high volume of pedestrians and potentially address jaywalking .
• Consider curb extensions at the existing crosswalk to reduce crossing distance, increase pedestrian
visibility, and deter parking close to the intersection.
• Evaluate if the road can be narrowed to be only one lane in each direction to prevent vehicles from
swerving around other vehicles.
• Evaluate the feasibility of installing a hawk signal or RRFB at the Main Street crosswalk to provide
increased safety for crossing pedestrians, being cognizant of the fact that this might encourage more
jaywalking of pedestrians due to the high volume of pedestrians in this area who are not used to
waiting.
• Consider widening sidewalks or converting some brick buffers to concrete sidewalks to ensure that
adequate sidewalk space is available for the pedestrian demand and to accommodate outdoor cafes.
Figure 28: PVTA buses stopped in front of Pulaski Park and
Academy of Music
Transit Accommodations
Observations
The bus stop in front of the Academy of
Music and Pulaski Park was identified by
the audit members as highly utilized with
multiple buses serving the stop (See
Figure 28). The stop has become
challenging with multiple buses
attempting to pull into the designated
stop that provides space for only two
buses. There is an on-street parallel
parking space located between the front
of the bus stop and the Main Street
crosswalk at Masonic Street. This
parking space was noted by RSA members to be important for deterring buses from parking too close to
the crosswalk. However, audit members noted that when the parking spot is not occupied, buses will still
park within the space and may encroach on the crosswalk. It was also noted that due to multiple buses
parked at the stop, eastbound vehicles often cross the double yellow centerline to go around the buses.
Page 34
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
• Consider marking out individual bus parking spaces (at Pulaski Park stop and the bus stop on the
north side across for buses going westbound) to ensure that buses have a designated space, and
consider providing additional queueing space for buses on an intersecting street to accommodate
longer bus layovers.
• Consider replacing the parking space between the crosswalk and bus stop with a curbed bump-out
to physically prevent the buses from encroaching on the crosswalk. This bump-out would also help
reduce pedestrian crossing distance and improve pedestrian visibility.
Parking and Loading
Observations
The audit team noted that since the closure of the Cracker Barrel Alley, Masonic Street has seen more
traffic, with some of the traffic from Main Street and some from Main Street to Center Street to Masonic
Street. The audit team members noted that the northeast corner of Masonic Street and northwest corner of
Main Street at Masonic Street was a common loading zone, however due to the narrow geometry of Masonic
Street this can cause additional congestion. In addition, the on-street parallel parking along Masonic Street,
at the corners of Main Street, restrict the visibility for southbound vehicles approaching the intersection.
Potential safety enhancements
• Evaluate potential designated loading zones to reduce potential conflict.
• Consider parking signage at Center Street/Main Street to direct vehicles to the Masonic Street lot.
Restrict parking within 20 feet of the intersection to improve visibility.
Main Street at Cracker Barrel Alley and
Crafts Avenue
Roadway Geometry
Observations
The Northampton City Hall driveway is a narrow one-way
alternating street with one access point for entry and exit,
with a difficult east facing line of sight for existing vehicles
(See Figure 29). The audit team discussed that this has
caused traffic delays and unsafe conditions when a vehicle
is exiting the driveway, and another is attempting to enter.
Additionally, pedestrians often don’t expect this crossing
and due to the nature of entry and exit points being in one
spot, they are often overlooked.
On the east side of City Hall, Crafts Avenue intersects Main
Street from the south and provides one-way travel
southbound away from Main Street. There is on-street
angled parking along the west side of Crafts Avenue and a
notable downward slope away from Main Street. The wide
Figure 29: City Hall parking entrance with
one access point for entry and exit
Page 35
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
geometry of Main Street at Crafts Avenue encourages vehicles to enter Crafts Avenue at excessive speeds.
The excessive speeds, downward slope, and on-street parking can make navigating the intersection difficult.
Crafts Avenue was discussed as an area with many simultaneous movements including movements into
and out of angle parking, wide left turns onto Crafts Avenue, and steep slope away from Main Street. When
combined, the confluence of these many movements can be difficult to process and navigate for motorists
as well as other users. Furthermore, the PVTA and Peter Pan currently runs bus routes down Craft Avenue.
Audit team members noted that right turns from Main Street eastbound onto Crafts Avenue is challenging
due to the width of the intersection.
Potential safety enhancements
• Consider closing the City Hall driveway or removing public parking in the lot to limit activity into
and out of the driveway.
• Consider closing Crafts Avenue to vehicle traffic.
• Evaluate the possibility of flipping the one-way operations for Crafts Avenue and Old South Street
to make Crafts Avenue one-way northbound and Old South Street one-way southbound.
Coordination with PVTA and Peter Pan buses would be necessary.
• Consider narrowing all sides of the intersection to control many movements occurring at the
intersection. This can potentially be achieved with stamped/scored concrete allowing for truck/bus
movements.
• Consider adding a turn pocket for the westbound left turn from Main Street to Crafts Avenue.
Signage
Observations
Audit members noted that the “Do Not Enter” sign is turned to be
parallel with the closed alley, rather than perpendicular (See Figure
30). Additionally, audit members mentioned that it can be difficult
to see the Crafts Avenue when travelling west on Main Street.
Potential safety enhancements
• Reposition “Do Not Enter” sign to be in appropriate
location to increase visibility.
• Remove the street name sign as the alley is closed to
traffic and consider installing a pedestrian oriented
wayfinding sign instead.
• Consider installing better signage earlier on westbound
approach of Main Street and Crafts Avenue to improve
street visibility.

Final Report
Pedestrian Accommodations and Crossings
Observations
Sidewalks on the northeast side and west of Cracker Barrel Alley were noted to be narrow. The crosswalk
across Main Street was also noted to be long with poor visibility due to parking on the north side and
southwest side of the intersection, a tight roadway curve to the east. Additionally, audit members noted that
it was difficult for vehicles to see pedestrians crossing Crafts Avenue because of steep grading, a parked
vehicle, newspaper boxes, and mailboxes at the southwest corner of Main Street at Crafts Avenue.
Potential safety enhancements
• Evaluate the feasibility of widening the sidewalks and/or installing sidewalk/curb extensions
around this area to add to more sidewalk space and shorten crossing distance.
• Consider RRFB treatment for the Main Street crosswalk due to existing horizontal curve of Main
Street.
• Evaluate installing pedestrian crossing warning signs for all crosswalks.
• Consider installing a raised crosswalk on Crafts Ave to increase pedestrian visibility.
• Consider restricting parking and relocating newspaper and mailboxes on the southwest corners of
the intersection to improve visibility between motorists and pedestrians.
Bicycle Accommodations
Observations
The audit team remarked that the New Haven and Northampton Canal Trail bike path begins south of Crafts
Avenue and Pulaski Park.
Potential safety enhancements
• Evaluate the feasibility of adding a connection along Crafts Avenue towards the rail trail/bike
path.
Transit Accommodations
Observations
Audit members noted that PVTA and Peter Pan buses go southbound on Crafts Avenue. The angle for the
right-turn from Main Street onto Crafts Avenue was brought up to be a challenge due to many movements
that could be conflicting at this intersection.
Potential safety enhancements
• Coordinate with PVTA and Peter Pan on changes to bus route, especially, if the roadway is to be
closed or if the one-way direction is changed.
Parking and Loading
Observations
Audit members noted that the loading/unloading zone in front of City Hall was too close to the crosswalk
which comes with sight line concerns.
Page 37
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
Potential safety enhancements
• Remove the parking spot in front of City Hall to create additional sidewalk space, potentially
shortening the crosswalk length, and improve pedestrian visibility.
Main Street at Old South Street
Roadway Geometry
Observations
The audit members discussed that Old South Street has
extremely steep grading which has led to vehicles
accelerating when they enter Main Street (See Figure 31).
This movement can be unsafe due to the potential of
conflicts between right-turning vehicles and the adjacent
Main Street crosswalk and left-turning vehicles and
oncoming eastbound traffic. Five (22.7%) crashes at this
intersection were reported during the study period that
involved right and left-turning vehicles and oncoming
eastbound and westbound traffic. In addition, there were two
crashes that occurred in the Old South Street crosswalk, one
involving a bicyclist and one involving a pedestrian, with a
northbound vehicle. Old South Street serves as one of the
exit routes from one of the busiest parking garages in the
Downtown area, which increases the potential of more
traffic conflicts. Furthermore, sightlines around this
intersection are poor due to both horizontal and vertical
curves in the roadway and vehicles are currently encroaching
onto the crosswalk. In addition, due to the significant slope
on Old South Street, the City of Northampton has reported occasionally closing this street to vehicles during
snowy and icy conditions.
Potential safety enhancements
• Install curb extensions and relocate the stop bar further north on Old Sou th Street so vehicles can
queue on flatter road surface and do not have to accelerate to pass the intersection.
• Due to the vertical/horizontal curves effect on the sight lines, vehicles encroach onto the crosswalk,
to prevent this, the flipping of one-way operations is being recommended as it would be safer/easier
movement. Consider closing Old South Street to vehicles.

Signage
Observations
Audit members noted that crosswalk signage was only provided at
the median and the signs were missing on the ends of the crosswalk
(See Figure 32).
Potential safety enhancements
• Install appropriate crosswalk signage in all directions.
Pedestrian Accommodations and Crossings
Observations
It was noted that the rainbow crosswalk was further away from the
Old South Street intersection which may be undesirable and pose
safety concerns. Parking spaces adjacent to the crosswalk was also
noted to cause visibility issues for pedestrians.
Potential safety enhancements
• Evaluate feasibility of moving rainbow crosswalk closer
to Old South Street intersection.
• Consider restricting parking before the rainbow crosswalk
to increase pedestrian visibility and after the crosswalk to prevent vehicles from backing into the
crosswalk.
• Evaluate feasibility of curb extensions to shorten the Main Street crossing and to increase
pedestrian visibility.
Main Street at Center Street
Roadway Geometry
Observations
The audit members discussed that Center Street has problems with limited sightlines. The left-turning
movement from Center Street was noted to be difficult because it involves crossing two westbound traffic
lanes just as traffic becomes more congested on the approach to the large Main Street/King Street/Pleasant
Street intersection.
Potential safety enhancements
• Consider restricting left turns and turning the intersection to a right-in and right-out roadway.
Evaluate installing a center median on Main Street to restrict left turn movements.

Final Report
Potential safety enhancements
• Install stop bar and sign on Center Street if it meets warrants.
• Consider installing a centerline on Center Street.
Pedestrian Accommodations and Crossings
Observations
Audit members noted that crosswalk visibility from Center Street is limited due to alignment, parking, and
oncoming traffic from Main Street. Additionally, the crosswalk across Main Street at this intersection was
noted to be very long and well-utilized with parking spaces on both sides of the crosswalk causing sight
line issues.
Potential safety enhancements
• Evaluate relocating the crosswalk on Main Street slightly west to provide better visibility from
right-turning vehicles from Center Street to Main Street.
• Evaluate making the crosswalk more perpendicular with Main Street to reduce crossing distance.
• Consider installing enhanced crossing treatments, such as a hawk signal or Rectangular Rapid
Flashing Beacon (RRFB)) at crosswalks to increase visibility and compliance.
• Consider restricting parking before the crosswalk to increase visibility.
• Evaluate feasibility of curb extensions to shorten the Main Street crossing and to increase
pedestrian visibility.
Main Street at Gothic Street
Roadway Geometry
Observations
The audit members discussed that Gothic Street has problems with limited sightlines. The street was also
noted to be used as a northbound cut-through for vehicles looking to avoid Main Street traffic. The left-
turning movement from Gothic Street was noted to be difficult because it involves crossing two westbound
traffic lanes and the beginning of three eastbound lanes (left turn to King Street, thru, and right lanes to turn
to Pleasant Street) which are often queued up.
Potential safety enhancements
• Consider restricting left turns and turning the intersection to a right-in and right-out roadway.
• Extend the median on Main Street to restrict left turns.

Observations
Audit members noted that Gothic Street does not have a stop
bar and sign or any centerlines (See Figure 33).
Potential safety enhancements
• Install stop bar and sign on Gothic Street if it meets
warrants.
• Consider installing a centerline on Gothic Street.
Pedestrian Accommodations and Crossings
Observations
Audit members noted that there were no crosswalks provided
across Main Street at this intersection. People were observed to
be jaywalking and using the traffic signals at King Street and
Pleasant Street to find gaps in traffic to cross.
Potential safety enhancements
• Consider installing treatments to deter pedestrians from
crossing and direct them to existing crosswalks at
King/Pleasant Street or Center Street since this
intersection is within 300 feet of an existing controlled intersection (King Street/Pleasant Street).
Consider extending the median and fencing.
Parking and Loading
Observations
The audit team noted that the angled parking spots at this intersection were 15-minute quick turnaround
type. Many frequent movements and backing out crashes were observed as a result. The crash reports show
that four (30.8%) out of the total 13 crashes at this location occurred with vehicles backing out of these
parking spots.
Potential safety enhancements
• Consider alternate parking schemes to prevent head-in angle parking crashes including removal of
parking spots, reverse-angle parking, parallel parking, etc.
Main Street at King Street and Pleasant Street
Roadway Geometry
Observations
The audit team noted that this intersection is extremely large and is traversed by a large volume of heavy
vehicle traffic from Pleasant Street northbound to Main Street westbound and Main Street westbound to
Figure 33: Gothic Street has no stop bar
or centerline. No crosswalk across Main
Street.

Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
Pleasant Street southbound (with a tight curb radii). To facilitate some of these movements, the City of
Northampton installed a westbound left-turn lane from Main Street to Pleasant Street southbound.
Potential safety enhancements
• Evaluate the impact of the new left-turn lane.
Pavement Markings and Conditions
Observations
Audit members mentioned that the eastbound right turning lane on Main Street is not well-marked and as
a result, vehicles don’t realize it is there and sometimes assuming it is a parking spot. The crash reports
show that there were four (14.8%) out of the total 27 crashes at this intersection that involved vehicles
getting side-swiped while making this turn. Furthermore, trucks as well as fire vehicles that were making
this turn were observed crossing the Pleasant Street centerline due to the tight radii. The left-turn pocket on
Pleasant Street was noted to be too short and identified as a potential contributor to the three side-swipes
crashes (11.1%) observed.
Potential safety enhancements
• Consider moving the stop bar on Pleasant Street further south to allow for adequate turning space
for trucks and fire vehicles without encroaching to the centerline and reducing any oncoming
traffic-related conflicts.
• Evaluate the feasibility of installing mountable truck aprons to keep the radii as is while allowing
truck movements
• Consider removing the right turn lane if the turning radii cannot be adequately accommodated.
• Consider installing clearer right-turn-only pavement markings for the eastbound right-turning lane
on Main Street.
• Consider moving the island on Main Street west of Pleasant and King northerly to provide more
space for the tight eastbound movements and reduce excess space for westbound movements.
Signal Equipment
Observations
The audit team noted that the pedestrian push buttons at this intersection were further away from the ramps
than stated in the ADA requirements. Additionally, each mast arm at this intersection has only one overhead
signal but each approach has multiple lanes with additional signals on the posts. Some of the signals were
also missing back plates and none of them have retroreflective borders.
Potential safety enhancements
• Evaluate if push button locations are ADA-compliant and if not, relocate to ensure compliancy.
• Evaluate adequate placement of signals equipment with respect to the number of approaching lanes
in all directions.
• Consider installing back-plates and retro-reflective borders to the signals to improve equipment
visibility.

Final Report
Signal Timing and Phasing
Observations
Exclusive pedestrian phasing is provided at this intersection.
The audit team noted that pedestrians cross diagonally at this
location to avoid the long signal cycle (See Figure 34).
However, the timing of the phase does not accommodate for the
distance to cross diagonally. It was also noted that the
pedestrian pushbuttons are “dummy” buttons and the WALK
phase is included in every cycle. Additionally, the cycle length
was over three minutes which creates excessive delays for all
roadway users and leads to aggressive disregard of signals.
Potential safety enhancements
• Adjust exclusive pedestrian time to accommodate for
diagonal crossing distance.
• Evaluate the appropriateness of providing concurrent
pedestrian crossings.
• Evaluate converting the “dummy” pedestrian
pushbuttons to actually activated pushbuttons so that
the exclusive pedestrian phase is only called when pedestrian actuated.
• Re-time existing cycle length so it is shorter to reduce pedestrian wait times.
Figure 34: Pedestrians observed crossing
diagonally on Main Street at King
Street/Pleasant Street
Signage
Observations
The audit members pointed out that the low clearance sign for the
two railroad bridges at this intersection located on the mast arm
was not very visible (See Figure 35). The lack of sign visibility
might have been a contributor to the eleven crashes involving
trucks with the railroad bridges.
Potential safety enhancements
• Evaluate the condition and location of the low clearance
sign to increase visibility. Ensure that the signage is MUTCD
compliant.

Pedestrian Accommodations
and Crossings
Observations
Members of the audit team noted that the
northwest corner of this intersection has
limited sidewalk space but has a high
volume of pedestrians looking to cross. That
corner is also next to a well-used bus stop
just west of an angled ValleyBike bikeshare
station that occupies the sidewalk space at
this corner (See Figure 36).
Potential safety enhancements
• Consider Northampton Courthouse
easement to widen this portion of
the sidewalk to accommodate more
pedestrians.
• Evaluate narrowing the roadway as it is currently too wide for two westbound lanes.
Main Street at Strong Avenue and the railroad bridges
Roadway Geometry
Observations
Audit team members observed that the Main Street
westbound traffic coming from Bridge Street doesn’t always
stop before making a left onto Strong Avenue.
Potential safety enhancements
• Evaluate feasibility of tightening the intersection at
Strong Avenue by using curb extensions that would
force vehicles to stop before turning and prevent
them from making a wide turn.
Pavement Markings and Conditions
Observations
The audit team observed that there were no pavement
markings on Strong Avenue which could be a source of
confusion. Additionally, the pavement surface was noted to
Figure 37: Parallel parking under the be cracking under the bridges. railroad bridges
Potential safety enhancements
• Install appropriate pavement markings on Strong Avenue.
Figure 36: ValleyBike bikeshare station at the northwest
corner of Main Street and King Street
Page 44
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
• Improve drainage under the bridge and repave as necessary to improve pavement conditions.
Signage
Observations
The audit team pointed out that the flashing lights indicating caution for trucks under the railroad bridges
for trucks is often on, which has resulted in people ignoring the sign. Audit members also mentioned that
the rail trail access from the bridge is hidden and non-intuitive.
Potential safety enhancements
• Evaluate feasibility for a laser actuated sign that will detect heavy trucks at adjacent intersections
for diversion from the railroad bridges.
• Install wayfinding tools to direct people to the rail trail access point.
Pedestrian Accommodations and Crossings
Observations
The audit team noted that the Main Street
crosswalk at Strong Avenue is diagonal due to
issues with sidewalk grading. Additionally, there
is a driveway with a steep curb cut adjacent to the
crosswalk on the north side of Main Street (See
Figure 38). This driveway portion was identified
to be Commonwealth-owned and can be
accessed by King Street or Merrick Lane. Sight
lines to and from the driveway were observed to
be restricted due to the on-street parallel parked
vehicles along the north side of Bridge Street
immediately east of the driveway. Pedestrian
access from parallel parking was also brought up
as a concern as currently, the sidewalk is at much
higher grade than roadway and people have to
walk on the travel lane after getting out of the parallel parking spot.
Potential safety enhancements
• Evaluate feasibility of removing the driveway and limit parking lot access to Merrick Lane from
King Street.
• If parking lot access can be closed, move crosswalk across Main Street to westbound approach for
better geometry.
• Consider curb extensions to shorten the pedestrian crossing on Main Street.
• Consider feasibility of safety enhancements including a secondary sidewalk at street level on one
or both sides of the street for people to access parking spaces. May require removal of parking from
one side of the street.

several truck collisions
Bicycle Accommodations
Observations
The audit team noted that there was very limited bicycle parking around this area.
Potential safety enhancements
• Consider installing more bicycle parking at this section.
Freight Accommodations
Observations
The audit team noted that truck collisions continue to be a
problem regardless of signage improvements. The crash
report identified that out of the total 20 crashes at this
location, 11 (55%) involved trucks hitting the bridge.
During the audit, there were dents on the westbound side
of the bridge that show evidence of the crashes (See Figure
39). The protocol for truck rescue was brought up to be a
big hassle requiring police effort, creating delays and other
issues. MassDOT members mentioned that they are
working with industry partners to warn drivers to change
their route well before Main Street near the highway. It
was also noted that currently, the truck escape route to
avoid the railroad bridges is to go down Hawley Street,
Philips Place, Pomeroy Terrace, and then to Bridge Street
eastbound. However, there are issues with trucks
travelling on these routes as the areas are residential and
potentially unsuitable as frequent truck routes.
Potential safety enhancements
• Evaluate feasibility for a laser actuated sign that
will detect heavy trucks at adjacent intersections for diversion from the railroad bridges, and a more
aggressive warning system with the police help number.
Bridge Street at Market Street and Hawley Street
Roadway Geometry
Observations
Audit members noted that Hawley Street is a key school walking route, that there is future residential
development planned, and the business district is expanding in this direction. The Post Office is located just
northeasterly of the intersection and audit members noted that this created vehicular movements along
Hawley Street and Bridge Street to access and egress the site while visiting the site or utilizing the site as a
cut-through to avoid the signal at the study area intersection. The high activity the Post Office driveways
Page 46
Road Safety Audit—Route 9, Northampton, MA
Prepared by Toole Design Group
Final Report
experience may have contributed to two crashes that involved a vehicle leaving the parking lot and the three
rear-end collisions potentially from vehicles abruptly deciding to enter the driveways.
Audit team members mentioned that Hawley Street is often the entrance to the route that trucks will use
upon realizing that they will not clear the bridge height restriction to the rail bridge across Bridge Street
immediately west of the intersection. Audit team members also noted the skewed offset between the Market
Street and Hawley Street approaches. The Market Street approach was noted to be particularly narrow while
the Hawley Street approach was noted to be wider. The wide geometry of Hawley Street and misalignment
of the minor street approaches at the intersection may have contributed to the reported five turning-vehicle
crashes that occurred within the intersection.
Potential Safety Enhancements
• Consider narrowing the Hawley Street approach to better align the Hawley Street and Market Street
approaches.
• Install lane tracking pavement markings.
Pavement Markings and Conditions
Observations
All approaches at the intersection of Bridge Street at Market Street
and Hawley Street provide one travel lane in each direction. Audit
team members noted that both Market Street and Hawley Street
provide no centerline separating the opposing travel lanes.
Potential Safety Enhancement
• Install double yellow centerlines along Market Street and
Hawley Street approaches.
Signal Equipment
Observation
The intersection of Bridge Street at Market Street and Hawley Street
is a signalized intersection that, as previously discussed under
Corridor-wide Observations, has dated signal equipment (See
Figure 40). Signal heads for Bridge Street are provided overhead on
mast arms, while the Market Street and Hawley Street approaches provide signal heads mounted on street
side posts. Audit team members also noted a telephone pole, and traffic signal pole located on the southeast
corner of the intersection are often struck by heavy vehicles who are forced to travel along Hawley Street
or Bridge Street eastbound due to the truck height restriction.
Potential Safety Enhancement
• Relocate Market Street and Hawley Street signal heads to overhead mast arms to increase visibility.
• Consider relocating the telephone pole to reduce the risk of heavy vehicles striking the pole while
performing a turn to or from Hawley Street

Final Report
Signal Timing and Phasing
Observation
The intersection of Bridge Street at Market Street and Hawley Street is a signalized intersection that
operates on a three-phase cycle, including an exclusive pedestrian phase. The cycle consists of both Bridge
Street eastbound and westbound approaches, followed by an exclusive pedestrian phase actuated by
pushbuttons, then the Market Street southbound and Hawley Street northbound approaches. Left-turn
movements from all approaches are permissive, which requires vehicles to attempt to find gaps within the
vehicular traffic traveling through the intersection. This may have been a contributing factor for the five
crashes within the intersection and involved a left-turning vehicle.
During the site visit, audit members observed multiple vehicles turn right during their red signal,
particularly during the exclusive pedestrian phase. Furthermore, multiple pedestrians were observed to
cross the intersection diagonally during the exclusive pedestrian phase. The existing signal phase provides
Flashing Don’t Walk time for pedestrians crossing a single approach and does not provide adequate time
for a pedestrian to safely traverse the intersection diagonally within the time provided.
Potential Safety Enhancement
• Evaluate providing protected left-turn phasing to increase safety for turning vehicles.
• Evaluate restricting right-turns on red to increase safety for pedestrians.
• Evaluate providing concurrent pedestrian crossing phasing to improve delay for all users.
• Retime the exclusive pedestrian phase to provide adequate crossing time for pedestrians crossing
the intersection diagonally.
Signage
Observation
The rail bridges overpass is located approximately 70 feet west
of the intersection of Bridge Street at Market Street and Hawley
Street. There is a bridge height restriction right located on both
directions along Main Street (See Figure 41). The bridge height
restriction sign was noted to not have the fluorescent ambers that
increase sign visibility.
Potential Safety Enhancement
• Replace the bridge height restriction signage with a high
visibility sign with ambers.

Re: Traffic Operations at Main Street at West Street/Elm Street and State Street/New South Street
Toole Design has prepared this technical memorandum to summarize operational considerations at the key
signalized intersections of Main Street at West Street/Elm Street and at State Street/New South Street as they
relate to the conceptual design progression of the preferred alternative (Alternative 3: three vehicle travel lanes
with expanded sidewalks, separated bike lanes, and angled parking1). It is intended that the information provided
in this memorandum be sufficient to vet the acceptability, tradeoffs, and opportunities associated with traffic signal
operational strategies related to pedestrian, bicycle, and vehicular users and the achievement of project goals.
Project Goals
Considerations for future operational strategies are to be evaluated as they relate to the evaluation criteria of
overall project goals as shown in Table 1.

operations are considered
At the intersection level, the application of the evaluation criteria offers guidance of how to balance operational
needs with the ability to meet project goals. This memorandum provides analyses related to the experience of
modal users (pedestrians, bicycles, vehicles) at the western signalized intersections in terms of safety, delay, and
experience as metrics which are directly applicable to some of the project’s evaluation criteria. Other criteria
however cannot be effectively measured at the intersection level, for example, the criteria of All modes having
separate and dedicated space for travel speaks to broader network connectivity and the potential for future use.
As a network is only as strong as its weakest link, it is important to recognize that consideration must be given in
the evaluation of intersection level analyses to the ramifications to broader network level considerations. For
instance, the decision to maintain an additional travel lane for vehicular capacity purposes may appear warranted
to satisfy the evaluation criteria of delay for people driving and taking transit on Main Street is minimized, but it
could easily have an exceedingly detrimental effect on providing dedicated space for travel for all users. In
reviewing this memorandum, it is important to keep the safety, economic, and sustainability goals of the greater
project scope at the forefront while evaluating the concentrated, intersection-level analysis.
Existing Conditions
Main Street at West Street/Elm Street is a three leg, actuated-coordinated, signalized intersection at the western
limits of the Main Street project area. West Street (Route 66) is a state numbered route beginning at Route 112 in
Huntington to the west with its terminus at Main Street in Northampton. The northbound approach of West Street
consists of a left turn lane and a right-turn lane. The Elm Street eastbound approach consists of a through lane
and a through/right-turn lane while the Main Street westbound approach consists of an exclusive left-turn lane and
a through lane. Median islands separate the eastbound and westbound approach and receiving lanes. Marked
3
crosswalks with curb ramps and flashing-hand pedestrian signal indications are provided traversing the West
Street northbound approach. A bike lane is provided along eastbound and westbound Main Street/Elm Street.
Main Street at State Street/New South Street is a four leg, actuated-coordinated signalized intersections
approximately 100 feet east of the West Street/Elm Street intersection. The Main Street eastbound approach
consists of a left turn lane, two through lanes, and a right turn lane. A conventional bike lane is provided between
the outermost through lane and the right turn lane and queue boxes are provided in front of the eastbound
approach. The Main Street westbound approach consists of a dedicated left turn lane, a through lane, and a right
turn lane. The State Street southbound approach consists of a shared left-turn/through lane and a right turn lane.
The northbound approach of New South Street consists of a right turn lane which is channelized and operates
freely despite there being a crosswalk traversing the lane approach. Crosswalks are provided across the northern,
eastern, and southern legs of the intersection in addition to a diagonal crosswalk from the southwest corner to the
northeast corner within the intersection field.
The Main Street at West Street/Elm Street and Main Street at State Street/New South Street intersections operate
with 110 second cycle lengths. At West Street/Elm Street, the eastbound and westbound approaches proceed
concurrently with the crosswalk traversing West Street (the westbound left turn is permitted through this phase).
The West Street northbound approach then follows (left turn and right turn) before a final phase consisting of a
protected phase for the Main Street westbound left turn with the West Street northbound right turn overlapping.
Figure 1. Main Street at West Street/Elm Street Existing Phasing
At State Street/New South Street, the Main Street eastbound and westbound left turns run concurrently with the
diagonal crosswalk through the middle of the intersection field and a State Street southbound right turn overlap.
Next, the crosswalks traversing State Street and New South Street receive a leading pedestrian interval (LPI)
before running concurrently with the eastbound and westbound through and right turn movements along Main
Street. The eastbound right turn receives a protected right turn arrow if the pedestrian push button for the
southern crosswalk is not actuated. When the crosswalk is activated, the eastbound right turn follows the through
movement green ball. Alternatively, the westbound right turn receives a green ball regardless if the northern
crosswalk is actuated or not. The northbound and southbound movements then operate sequentially with split
phasing while the eastbound right turn and westbound right turn overlap, respectively. The New South Street
northbound right turn and crosswalk across the channelized right turn are not integrated to the signal and are free
running. The eastern crosswalk from the channel island to the north side of Main Street runs concurrently with the
northbound left-turn/through movement.

Traffic Counts
Traffic volume data were collected to analyze vehicular traffic, pedestrian activity, and bicycle usage throughout
the study area. Turning movement counts (TMCs) were collected on Wednesday, May 1, 2019 from 7:00 am to
9:00 am and from 3:00 pm to 7:00 pm. At Main Street at West Street/Elm Street, the intersection peak hour is
from 8:00 am to 9:00 am and the evening peak hour is from 4:15 pm to 5:15 pm. At Main Street at State
Street/New South Street, the intersection morning peak hour is from 7:45 am to 8:45 am and the evening peak
hour is from 4:30 pm to 5:30 pm. Analysis determined the network peak hour, including all unsignalized and
signalized intersections in the greater project scope, is from 8:00 am to 9:00 am on weekday mornings and 4:45
pm to 5:45 pm on weekday evening as indicated in Table 2. The network peak hour was used in evaluation of
both western intersection to achieve consistent vehicular conditions throughout the corridor.

Vehicular Operations
Vehicle operations including volume-to-capacity (V/C) ratio, delay, level of service (LOS), and queue lengths were
evaluated using Synchro 10 software as outlined in Appendix B and are summarized in Table 3. In addition to the
Synchro output results, SimTraffic simulations were run to better understand the queueing between both
intersections and the likelihood of queue spillback. In the morning and evening peak hour, all movements at Main
Street at West Street/Elm Street operate at LOS D or better which is considered acceptable at signalized
intersections in urban environments. At the Main Street at State Street/New South Street intersection, the
eastbound through movement in the morning peak hour, the westbound through movement in both peak hours,
the northbound left-turn/through movement in both peak hours, the southbound left-turn/through movement in
both peak hours operate at LOS E or F in existing conditions. The queueing space available for the westbound
Main Street approach to West Street and the eastbound Main Street approach to State Street/New South Street is
approximately 100 feet long. Avoiding gridlock through keeping the space between these two intersections is
important due to the potential for spillback within the limited stacking distance available. Synchro 10 outputs are
attached in Appendix C.

Pedestrian Facilities and Operations
Pedestrian LOS metrics are based solely on delay and the concepts and procedures in the Highway Capacity
Manual (HCM)2, as outlined in Appendix D. People walking through Main Street at West Street/Elm Street are
served by the southern crosswalk operating concurrently with the eastbound through/right-turn movement and the
permitted westbound left-turn/through movement within the intersection’s 110 second cycle. Under existing
conditions, people using the crosswalks at the intersection experience an average pedestrian delay of 48
seconds, or LOS E, to cross the West Street approach. LOS E reflects a high likelihood of noncompliance.
No crosswalk is provided across Main Street/Elm Street at the western intersection, requiring pedestrians
attempting to cross to the north side to either use the crosswalk at Bedford Terrace approximately 475 feet east of
West Street or the diagonal crosswalk at State Street/New South Street. Assuming use of the State Street/New
South Street diagonal crosswalk, it would take a pedestrian approximately 198 seconds to cross from the
southwest corner of West Street/Elm Street to the north side of Main Street in existing conditions in the evening
peak hour (Figure 4, Figure 5, Table 4).

At State Street/New South Street, the northern and southern crosswalks receive LPIs and therefore experience a
38-second average pedestrian delay, or LOS D, while pedestrians using the eastern crosswalk experience an
average pedestrian delay of 45 seconds, or LOS E. Although the northern and southern crosswalks experience
favorable pedestrian delays, the 7-second LPIs at these crosswalks are to help mitigate the frequent conflicts
between the high-volume permitted eastbound right turn and the southern crosswalk when actuated.
Bicycle Facilities and Operations
Conventional bike lanes are provided in both directions along Main Street/Elm Street west of State Street/New
South Street. Main Street east of State Street/New South Street does not have bicycle facilities so people biking
eastbound are expected to merge into the bike lanes after the State Street/New South intersection. As Elm Street
eastbound through drivers and bikers approach the Main Street eastbound approach, people biking need to
weave with Main Street eastbound right turning vehicles who have a dedicated turn lane onto New South Street.
The weaving pattern leaves people biking exposed and mixed in motor vehicle traffic through the large
intersection while those vehicles sort into their respective approach lanes heading towards State Street/New
South Street.
9
As a roadway with two travel lanes in each direction, a 4-5 foot bike lane, and a 25 mph speed limit, a person
biking Main Street west of State Street/New South Street experiences a Level of Traffic Stress (LTS) rating of 2,
per the metrics outlined in Appendix E. Though the general metrics of the roadway grant a low, and therefore
more comfortable LTS west of State Street/New South Street, the weaving pattern through the eastbound
approaches make for a hostile environment for bicycles, especially considering the high volumes (337-357 vph in
the peak hours) of eastbound right turning vehicles onto New South Street that merge through the conflict zone.
East of New South Street, the rating worsens to LTS 3 when the bike lane is removed and people biking must ride
in mixed traffic.
Safety Analysis
Road Safety Audit
A Road Safety Audit (RSA) was conducted on Thursday, November 21, 2019 with local and state stakeholders for
the approximately half-mile segment of Main Street between Elm Street/West Street to the west and Market
Street/Hawley Street to the east. As part of the RSA process, participants reviewed crash data throughout the
corridor before a field visit to identify and attribute roadway features and issues to those crashes. The crash
diagram at Main Street at West Street/Elm Street and State Street/New South Street is represented in Figure 6
and the accompanying summary table is attached in Appendix F.
Figure 6. Collision Diagram at Main Street at West Street/Elm Street and State Street/New South Street between 2015
and 2017
10
Among both intersections there were 36 crashes in the period analyzed between 2015 and 2017, twelve (33%) of
which resulted in non-fatal injuries. The three most frequently reported crash types include:
Angle collisions (14 crashes, 39%);
Rear-end collisions (10 crashes, 28%); and
Sideswipe (same direction) collisions (6 crashes, 17%).
Angle Collisions
RSA attendees attributed the majority of the angle collisions at both intersections to the wide roadway, offset
geometries, and inconsistent signal equipment and indications that complicate turn movements and confuse
drivers. For example, the Main Street westbound left turn lane onto West Street and the Main Street westbound
right turn lane onto State Street are not provided dedicated signal indications, and instead utilize the indications
provided for the through lanes. Missing indications such as these were noted to be confusing because drivers are
unsure how their movement is controlled within the dedicated turning lanes. Furthermore, while the signal
indications for Main Street, Elm Street, and West street approaches are mounted on mast arms, the indications
for the State Street and New South Street approaches are post mounted on the far side of the intersection. Post
mounted indications are acceptable by MUTCD standards in certain settings; however, mast arm mounted signal
indications provide greater visibility of signal heads which can enhance driver understanding of signal timing and
phasing as they approach an intersection3. Due to the skewed nature of Main Street at State Street/New South
Street, signal visibility is important in maintaining controlled flow through the intersection.
Sideswipe Collisions
The six sideswipe collisions at the intersections were primarily attributed to poor pavement markings, sign clutter,
and poor advance lane assignment signage. There are no lane assignment designations for the West Street
northbound approach or Main Street approach at State Street, and the Main Street eastbound approach at New
South Street consists of two through lanes but the receiving lanes are wide and unmarked. The pavement
markings and signage are also inconsistent or poorly placed in some locations. For instance, the Elm Street
eastbound approach operates as a dedicated through lane and a shared through/right-turn lane. There are no
advance warnings or pavement markings ahead of the intersection indicating that the outer lane of Elm Street is a
right-turn only lane, but at the intersection a “RIGHT LANE MUST TURN RIGHT” sign faces the eastbound
approach. Though the sign is likely a warning sign for the Main Street eastbound right turn at New South Street,
the placement faces the Elm Street eastbound approach at West Street which may confuse drivers.
Rear-end Collisions
Roadway and traffic control features that are most often attributed to rear-end collisions, as seen on all legs of the
intersection, include inadequate change intervals, speeding to avoid delay, poor signal visibility, and poor
pavement friction. RSA team members noted that many of the crashes at the intersection were congestion
related, specifically the ten rear-end collisions. The relatively worse visibility of the post mounted indications, as
compared to those that are mounted on mast arms, may also be attributed to these rear-end collisions.
Additional Observed Deficiencies
3 Manual on Uniform Traffic Control Devices, Part 4D: Traffic Control Signal Features, Section 4D.11 Number of Signal Faces on an Approach,
Support 06 (https://mutcd.fhwa.dot.gov/htm/2009/part4/part4d.htm)
11
In addition to the features attributed to collisions above, the RSA noted additional roadway and traffic control
deficiencies that may be confusing or unsafe to drivers, pedestrians, and cyclists through the intersections. First,
the driveway on the south side of Main Street between West Street and New South Street was noted to incite
unpredictable turning movements going into and out of the driveway. RSA team members observed Main Street
westbound drivers at West Street making a U-turn and cutting across all eastbound approach travel lanes to
access the driveway. The team also saw drivers turn left out of the driveway, continue in the opposing eastbound
approach travel lanes, and then merge into Main Street westbound traffic within the intersection. Both movements
are unpredictable and unsafe for people driving through Main Street at West Street/Elm Street and State
Street/New South Street.
The RSA noted several deficiencies for people walking and biking through both intersections. At West Street/Elm
Street, team members said that the proximity to Smith College evokes high volumes of jaywalking on Elm Street
between Bedford Terrace and West Street, some using the median island along Elm Street at West Street as a de
facto median island despite no marked crosswalks or curb ramps. The curvature of the Elm Street eastbound
approach also results in the rear passenger side corner of vehicles blocking the bike lane. Blocking the bike lane
makes it more difficult for people biking to establish themselves ahead of vehicles during a red light. When
bicycles have full access, they may ride to the front of the queue and establish themselves ahead of vehicles so
they may have priority through their approach to New South Street that requires weaving between vehicles and
bicycles. With the approach blocked, people biking are in the mix of vehicle traffic through the large conflict zone.
At State Street/New South Street, the Main Street eastbound right turn lane is controlled by a green ball when the
southern crosswalk is actuated by a pedestrian and with a green arrow when the crosswalk is not actuated. RSA
team members noted that the permitted/protected control is confusing and suggested evaluating the effectiveness
of having the movement be protected or permitted, not permitted/protected.
For people crossing along the diagonal crosswalk from the southwest corner to the northeast corner at State
Street/New South Street, the provided crosswalk is faded and difficult to see. Considering the nature of the
crosswalk through the middle of the intersection during concurrent left turn phases, it is important that they are
highly visible during the long exposure. The Main Street eastbound and westbound left turns run concurrently with
the pedestrian crossing that calls for 31 seconds when actuated. This time was noted to be too long for those
vehicular movements, and it was suggested that the crosswalk layouts be adjusted and any additional time within
the cycle be reallocated to other movements, specifically the State Street southbound approach that was said to
only allow approximately three vehicles to exit before the end of its phase. RSA team members noted that the
timing and phasing of both signals was “inefficient in meeting the needs of existing traffic demands.” Finally, the
bicycle queue boxes at the Main Street eastbound approach to New South Street are not painted green and their
placement after the short block between West Street and New South Street makes it difficult for people biking to
utilize them.
Pedestrian and Bicycle Audit
In January 2016, WalkBoston and MassBike conducted an assessment of pedestrian and bicycle facilities
provided along Main Street between West Street/Elm Street and King Street/Pleasant Street. The assessment
captured pedestrian and bicycle activity while local colleges were in session and while those modes saw their
highest activity throughout the year. Key findings of the report highlight the walkable environment of downtown
Northampton but identify the wide cross section of Main Street as a barrier between the shops, restaurants, and
other amenities on either side of the street. The undefined lanes and poor sight distances due to parked cars was
attributed to the crashes involving pedestrians and rear ends when drivers unexpectedly yield to pedestrians in
crosswalks. Furthermore, the assessment said the wide, undefined travel lanes, angled parking, and complex
intersections make it difficult to navigate Main Street on a bicycle.
12
At Main Street at West Street/Elm Street and State Street/New South Street there were 48 collisions recorded
between January 2012 and August 2015, seven of which involved people walking and biking at the intersections
(Figure 7). The collision diagram and summary table for the crash period analyzed in the audit, January 2012 to
August 2015, is included in Appendix G. All bicycle/pedestrian collisions resulted in injury and in four of the seven
crashes, the person walking or biking was struck within a crosswalk. Permitted left turns, wide geometry, and
large conflict zones were primarily attributed to the collisions with people walking and biking through the
intersections. Specifically, the weaving zone for Elm Street eastbound drivers going to the Main Street eastbound
right turn lane onto New South Street was called out as particularly uncomfortable to bike along. The audit noted
that the curvature of the roadway and the larger corner radius of the southwest corner at New South Street allows
motor vehicles to drive at high speeds through the large conflict zone where bikes are provided green markings.
Audit team members recommended installed left-turn boxes, installing flashing yellow arrows, restriping
crosswalks, and adjusting corner radii to make the roadway friendlier to people walking and biking through the
intersections.

January 2012 and August 2015
Preferred Geometric Design and Phasing Implications
The preferred geometry throughout the project corridor reduces the existing cross section down to one travel lane
in each direction with separated bike lanes for people biking and expanded sidewalk spaces for people walking.
Due to the proposed geometry, several factors are vital for consideration in development of all alternatives.
Phase Separation
At Main Street at Elm Street/West Street, the preferred design provides the Elm Street eastbound approach a
through lane and a dedicated right-turn lane, the Main Street westbound approach with a dedicated left turn lane
and a through lane, and the West Street northbound approach with a left turn lane and a right turn lane. People
biking eastbound are provided their own dedicated space and no longer have to weave with eastbound motorists
on the approach to State Street/New South Street. People walking along the southern crosswalks are provided a
13
shorter crosswalk with shorter exposure across West Street and a new crosswalk across Elm Street is proposed
to address the observed jaywalking on that western leg.
In relation to the addition of the separated bike lanes, guidance from the MassDOT Separated Bike Lane Design
Guide (SBLDG) recommends phase separation when motor vehicle turning volumes across a one-way separated
bike facility are greater than 100 vehicles per hour (vph) turning left across one travel lane and greater than 150
vph for right turning vehicles (Figure 8). The existing Elm Street eastbound right turn volumes exceed the 150 vph
threshold in the morning peak hour and the Main Street westbound left turn volumes exceed the 50 vph threshold
in all peak hours (Figure 3). Due to the introduction of the separated bike lane across West Street, these two
movements must be phase separated with the proposed geometry.
Figure 8. MassDOT SBLDG Recommendations for Phase Separated Bicycle Movements4
At State Street/New South Street, the preferred design provides the Main Street eastbound approach with a
dedicated left turn lane, a through lane, and a right turn lane. Removing one eastbound through lane allows the
separated bike lane to be maintained through the intersection, providing one continuous facility throughout the
corridor. The Main Street westbound approach consists of a dedicated left turn lane and a shared through/right-
turn lane while the State Street southbound and New South Street northbound approaches consist of a shared
left-turn/through lane and a dedicated right turn lane. The diagonal crosswalk orientation is removed and
traditional crosswalks across each leg of the intersection are provided for each movement. With the preferred
design, the existing volumes for the Main Street eastbound right turn, the Main Street eastbound left turn, and the
Main Street westbound exceed MassDOT SBLDG for concurrent separated bike lane movements in all peak
hours, and therefore require phase separation. Phase separating the Main Street eastbound right turn serves to
address the existing non-compliant protected movement that runs concurrently with the southern crosswalk
across New South Street.
4 MassDOT Separated Bike Lane Design Guide, Chapter 6: Signals. (https://www.mass.gov/doc/chapter-6-signals/download)
14
In summary, the following movements require phase separation from separated bike lanes movements at both
intersections based on existing turning movement volumes in one or more peak hours that exceed MassDOT
SBLDG thresholds:
Elm Street eastbound right turn onto West Street;
Main Street westbound left turns onto West Street;
Main Street eastbound left turns onto State Street;
Main Street eastbound right turns onto New South Street; and
Main Street westbound left turns onto New South Street.
Right Turn on Red Operations
In the phasing alternatives developed for these intersections, bicycle movements along the separated bike lanes
are proposed to be controlled with pedestrian signal heads through implementation of “BIKE USE PED SIGNAL”
signs (R9-5). The use of the R9-5 sign is proposed for several reasons including overall project equipment and
maintenance cost, impacts to vehicle delay, and existing regulations for dedicated bike signals which are currently
undergoing revisions are part of the update to the MUTCD. In accordance with the 2009 MUTCD, “The R9-5 sign
may be used where the crossing of a street by bicyclists is controlled by pedestrian signal indications.” proposed
arrangement will clarify and help guide desired behavior. For all approaches, ‘BIKE YIELD TO PED’ signs (R9-6)
are proposed to clarify priority for pedestrians over people making turning movements on bikes. Further
discussion of bicycle signalization is included in Appendix H. With shared signals for bicycles and pedestrians, the
same phase-separation requirements for the separated bike lanes therefore apply to pedestrian phasing. As such,
restricting right turns on red (ROTR) across the separated bike lane should be implement based on MassDOT
SBLDG recommendations5. A summary of the existing RTOR restrictions and what is proposed with the
installation of separated bike lanes is summarized below in Table 5:

Pioneer Valley Planning Commission Local Technical Assistance Study
The Pioneer Valley Planning Commission (PVPC) conducted traffic analysis on Main Street at West Street/Elm
Street and Main Street at State Street/New South Street in 1996 to propose short-term and long-term alternatives

to address traffic congestion at the intersections. The study can be found attached in Appendix I. Some of the
primary features proposed through the study were to install a dedicated left turn lane for the New South Street
northbound approach, install a crosswalk across the western leg of West Street/Elm Street, and either convert the
driveway between the two intersections to entrance only or install “Right Turn Only” signs. In addition to these
primary strategies proposed, the PVPC also recommended evaluating “alternative strategies to reduce existing
and future congestion along the Route 9 westbound and State Street approaches to the intersection,” including:
Prohibiting left turn movements;
Implementing one-way roadways within the downtown area; and
Timed turn restrictions.
The primary and alternative strategies proposed by the PVPC were considered in development of alternatives for
Main Street at West Street/Elm Street and Main Street at State Street/New South Street.
Alternatives Description
Four alternatives were evaluated for implementation at West Street/Elm Street and State Street/New South
Street:
Alternative A: Preferred Geometry
Alternative B: Preferred Geometry with Volume Reductions
Alternative C: Preferred Geometry without the State Street Southbound Approach
Alternative D: Additional Main Street Eastbound Through Lane
The preferred geometry sees one general purpose eastbound and westbound travel lane feeding both
intersections with additional turn lanes where phase separation is required based on MassDOT SBLDG
recommendations. The preferred geometric design is attached in Appendix J. Alternative A, B, and C all maintain
the preferred geometry and Alternatives B and C propose two mitigation tactics with the intent of improving
operations. Alternative D introduces another eastbound through lane, requiring removal of the separated bike lane
in both directions and warranting some adjustments to the phasing applied to Alternatives A, B, and C. Further
discussion of each alternative is provided below. Though the phasing is generally the same for each alternative,
the proposed signal timings, cycle lengths, and coordination settings vary to best accommodate each alternative.
Consistent with all alternatives is the proposed conversion of the driveway between the two intersections to be
entrance-only to address conflicts resulting from unpredictable turning movements when exiting the driveway.
Alternative A, Preferred Geometry Phasing
At Main Street at West Street/Elm Street, the preferred phasing begins with the Main Street westbound through
running concurrent with the westbound left and West Street northbound right turn before the Elm Street
eastbound through movement begins. The eastbound through runs concurrent with the southern crosswalk and
eastbound separated bike lane, terminating before the eastbound right turn begins. Finally, the West Street
northbound left and right turn run concurrent with the western crosswalk. Phasing at the Main Street at West
Street/Elm Street intersection can be seen in Figure 9.
16
Figure 9. Main Street at West Street/Elm Street Alternative A Phasing Diagram
The Main Street at State Street/New South Street preferred phasing has lead/lag left turn phasing for the
eastbound and westbound approaches, beginning with the Main Street eastbound through, eastbound left, and
State Street southbound right turn running concurrently with the crosswalk traversing New South Street and
eastbound separated bike lane. Once the southern crosswalk phase is complete, the Main Street eastbound right
turn runs concurrently with the eastbound and westbound through movements. Then, the Main Street westbound
left turn and through movements run concurrent with the New South Street northbound right turn. The crosswalk
traversing State Street and westbound separated bike lane also run concurrently with these phases. The New
South Street northbound approach then overlaps with the Main Street eastbound right and the eastern crosswalk,
followed by the State Street southbound approach and the western crosswalk. The diagonal crosswalk in existing
conditions is converted to two crosswalks, one across the western leg of Main Street at State Street/New South
Street and one across the eastern leg. Under these conditions, the eastbound and westbound left turn
movements no longer must be timed to accommodate crossing the diagonal crosswalk, and that additional time
can be reallocated to other movements. All crosswalks except the western crosswalk at State Street/New South
Street are on pedestrian recall. The western crosswalk is not on recall but the removal of the diagonal crosswalk
and the addition of the western crosswalk across Elm Street provides more traditional and consistent crossing
opportunities from the north side of the corridor to the south. Alternative A phasing at Main Street at State
Street/New South Street can be seen in Figure 10.
Figure 10. Main Street at State Street/Elm Street Alternative A Phasing
17
Both intersections operate with a 130 second cycle length and prioritize eastbound/westbound operations to
minimize queue spillback given the close proximity of the two intersections. V/c ratios are less than 1.00 for all
movements at both intersections.
Alternative B, Preferred Geometry Phasing with Volume Reductions
Alternative B maintains the same preferred phasing and geometry of Alternative A but reduces traffic volumes by
10%. Conventional engineering practices give priority to avoiding traffic congestion over other important functions
of streets. This practice has left cities with streets that carry more vehicular traffic than necessary and conditions
that are undesirable and unsafe in supporting a multimodal, vibrant downtown, especially for people walking and
biking. If a vehicle trip is made easy and cheap in terms of time and/or money with conveniences such as free
parking and uncongested roads, more people will choose to drive. “Induced traffic” is a term that describes an
increase in motor vehicle traffic volume that follows a project’s attempt to increase capacity or reduce vehicle
travel times. If the capacity of a street or network is reduced or changes are made that increase travel time and
lower speeds, driving becomes a less appealing travel choice, thus resulting in a reduction or traffic volume, or
“traffic evaporation.” While some trips are still necessary to access offices, schools, medical appointments,
grocery stores, and shops, others can be diverted to other modes, routes or times of day, or not made at all67
(Figure 11).

18
The application of “traffic evaporation” for this analysis is supported by the proposed implementation of separated
bike lanes and enhanced sidewalk and pedestrian facilities along Main Street that encourage a mode shift.
Current research shows that high quality biking infrastructure can result in an increase in bicycle trips, a trend that
is seen across the US in all types of climates and communities9. While there is currently insufficient data for
Northampton to develop an estimate of future bicycle demand on Main Street, or of a mode shift to bicycle trips,
research consistently points towards seeing an increase in bicycle use resulting from providing protected and
connected facilities.
In addition to the potential for “traffic evaporation”, throughout the COVID-19 pandemic there have been vast
changes in traffic patterns since March 2020, and is continuously evolving. Peak hour traffic counts for the greater
Main Street project were conducted in 2019 and are likely higher than current volumes on Main Street due to
changes in commuting patterns. It is expected that some employees will continue working remotely indefinitely
into the future, continuing to alter traffic patterns relative to pre-COVID collected data. While more recent TMCs or
automatic traffic recorder (ATR) counts are not available for Main Street, MassDOT maintains permanent count
stations on Pleasant Street just north of interstate 91, collecting ATR counts about every three years10. The 2021
traffic counts conducted in February are approximately 13% lower than those conducted in 2018 (Figure 12). The
decrease relative to historic traffic counts may reflect a new “normal” and what conditions a traffic analysis should
consider. The 10% figure chosen for reducing 2019 traffic counts stems from the historic counts relative to
COVID-19 trends in conjunction with “traffic evaporation” and potential for mode shift.
Figure 12. Average Annual Daily Traffic Count History on Pleasant Street
A 115-second cycle length at both intersections maintains v/c ratios less than 1.00.
Alternative C, Preferred Geometry Phasing without the State Street Southbound Approach
Alternative C assumes the same preferred phasing and geometry as Alternative A with the exception that the
State Street southbound approach has been closed. The closure expands on the alternative strategies proposed
by the PVPC study and allows the phasing at Main Street at State Street/New South Street to be simplified.
Without the State Street southbound approach, the final phase shown in Figure 10 and the southbound right-turn

overlap in the first phase can be removed and the additional capacity gained can be reallocated to other
movements.
The vehicle trips that currently travel through the southbound approach are reassigned and distributed throughout
the network to represent rerouted trips that will occur due to the closure. Origin-destination data is not currently
available and therefore trips are distributed based upon land-use patterns and available network connections. It is
expected that Center Street and Bedford Terrace will accommodate most displaced State Street trips. Of those
vehicles making a left turn from State Street, it is expected that that most (80%) of those vehicles will turn left at
Center Street and the remaining vehicles (20%) will utilize other side streets, in conjunction with King Street, to
access destinations east of State Street. Due to the limited availability of routes to access homes along South
Street, south of Main Street, it is expected that 90% of State Street southbound through trips will turn right onto
Bedford Terrace, turn left onto Main Street to continue eastbound through West Street/Elm Street, and then turn
right onto New South Street. The remaining 10% of southbound through vehicles are expected to permeate
through the network and find alternate routes beyond the study area. Finally, 25% the State Street southbound
right turns are expected to turn right onto Bedford Terrace, turn left at Main Street to go eastbound, and then turn
right onto West Street. The remaining 75% are expected to use Bedford Terrace to continue westbound along
Main Street. Respective adjustments are made to the Main Street westbound approach to West Street as well.
The reassigned trips and distribution throughout the network are depicted on Figure 13.
Figure 13. Redistributed State Street Southbound Approach Trips

Removing the southbound approach, and its associated phase, permits the use of a lower cycle length at both
intersections (120 seconds) while maintaining v/c ratios less than or near 1.00 for all movements.

Alternative D assumes the same phasing as Alternative A, however, to provide additional capacity to the
intersection, Alternative D introduces a second eastbound through lane between West Street and Masonic Street
and converts the Elm Street eastbound approach to consist of a through and a shared through/right-turn lane.
With the introduction of the additional through lane, separated bike lanes cannot be implemented west of Masonic
Street in either direction while also maintaining the Pioneer Valley Transit Authority (PVTA) bus stop on the
eastern leg of Main Street at State Street/New South Street. See
Figure 14 for a conceptual cross-section within the existing right-of-way of the spatial implications of introducing
an additional travel lane for the block between New South Street and Masonic Street. Relative to the preferred
geometry in this block (Figure 15), Alternative D essentially trades the separated bike lanes for the additional
travel lane. Alternative D would see the Elm Street eastbound approach converted back to consist of a through
lane and a through/right turn lane, meaning there cannot be phase separation for eastbound right turning vehicles
onto West Street across the southern crosswalk. Phase separation for the southern crosswalk across New South
Street is maintained, but eastbound bicycles must travel within the vehicular travel lane.
Both intersections in Alternative D operate under a 120 second cycle length that maintains v/c ratios less than
1.00 for all movements.

Alternatives Intersection Capacity Evaluation
Each alternative was evaluated using Trafficware Synchro with SimTraffic (version 10.3). Synchro is a
macroscopic traffic evaluation software utilizing methodologies put forth in the Highway Capacity Manual (HCM)
where SimTraffic is a microsimulation model that is used to evaluate real-world conditions in more complex
environments. HCM 2000 methodologies were used to compute level of service (LOS), delay, and v/c ratios
because HCM10 and HCM6 methodologies cannot support non-standard phasing (such as split-phased
operations). Synchro’s percentile delay methodology was used to calculate queueing at these two intersections.
Synchro’s percentile delay method is commonly used at closely spaced actuated-coordinated signals to
accurately capture the effects of coordination on intersection operations. While both 50th and 95th percentile
queues are provided, when upstream intersections are at or near capacity, 50th percentile queues represent the
maximum queue experienced11. SimTraffic simulations were also used to evaluate queueing and its associated
impact on traffic signal operations.
Some turning movements’ v/c ratios approach 1.00; v/c ratios greater than 0.85 indicate the intersection is
operating near capacity and disruptions to typical traffic patterns can quickly degrade network performance. When
v/c ratios approach or exceed 1.00, simulation models may present incomplete results as queues begin to impact
traffic signals’ ability to process vehicles (i.e., through green starvation). To ensure that the SimTraffic model
adequately processed real-world traffic volumes and was not impeded by queue spillback, the traffic volumes
processed were compared to those traffic volumes collected in the real-world using a simulation evaluation
statistic known as the GEH statistic12, and is shown in Equation 1. When the GEH Statistic is less than 5.0, it
suggests that the simulation is an accurate representation of real-world conditions. Values between 5.0 and 10.0
still likely represent real-world conditions, though a higher value should warrant further investigation of the
parameters of the model. The SimTraffic results indicate that the model outputs likely represent real-world
conditions, including queueing and delay, based on the GEH Statistic value for all alternatives in both peak hours.

Morning Peak Hour Intersection Capacity Analysis
The capacity analysis for all alternatives for the morning peak hour are summarized in Table 6 and output reports
are attached in Appendix L. All movements operate at LOS D or better with the exception of those discussed
below.
Alternative A
The Elm Street eastbound right turn, the Main Street westbound left turn onto West Street, and the West Street
northbound left operate at LOS E.
At the Main Street intersection with State Street/New South Street, the Main Street eastbound left, Main Street
eastbound through, Main Street westbound left, Main Street westbound through/right, New South Street
northbound left/through, and State Street southbound left/through operate at LOS E or F. Though more
movements at the intersection operate at high LOS rating compared to existing conditions, all movements have a
v/c ratio less than 1.00 and overall intersection delay and LOS similar to existing conditions. As previously
discussed, the phasing and timing of Alternative A integrates the New South Street northbound right turn into the
signal and rectifies the Main Street eastbound right turn violation. Proposed operations balance the delay among
all approaches at State Street/New South Street.
Alternative B
While the Main Street eastbound left turn at the intersection with West Street/Elm Street operates at LOS E, the
SimTraffic outputs indicate shorter queues when compared with existing conditions. At State Street/New South
Street, the Main Street eastbound left, Main Street eastbound through, Main Street westbound left, New South
Street northbound left/through, and State Street southbound left/through operate at LOS E or F; however, all
movements have a v/c ratio of less than 1.00. The operations of this alternative are reflective of what future
conditions may look like, considering post-COVID traffic trends, Northampton sustainability goals, and potential
mode shift.
Alternative C
Under Alternative C conditions, all movements operate at LOS E or better. At West Street/Elm Street, the Main
Street westbound left operates at LOS E with a v/c ratio less than 1.00 and SimTraffic queue lengths comparable
to exiting conditions. At State Street/New South Street, the Main Street eastbound left turn and the Main Street
eastbound through movements operate at LOS E with v/c rations less than 1.00. SimTraffic queues for these two
movements are similar to those in existing conditions.
Alternative D
At West Street/Elm Street, all movements operate at LOS D or better. At the State Street/New South Street
intersection, the Main Street eastbound left, Main Street westbound left, Main Street eastbound through/right,
New South Street northbound through/right, and State Street southbound left/through operate at LOS E or F.
Similar to the other alternatives, v/c rations less than 1.00 are maintained.
23
Alternatives Comparison
Consistent in all alternatives is the degraded performance of the Elm Street eastbound vehicular through
movement. In Alternatives A, B, and C, increased queuing is a result of converting the approach from a through
and through/right lane to a through and right-only lane, restricting right turns on red, and restricting the right turns
to a protected-only phase. In Alternative D, the degradation is due to restricting turns on red. Alternative B
experiences the shortest Elm Street eastbound through queue lengths, less than half all other alternatives. Phase
separating right turn, restricting right turn on red movements, and the use of lower cycle lengths improves safety
for people using the southern crosswalk and people biking eastbound along Main Street by removing turning
conflicts and reducing pedestrian and bicycle delay.

Evening Peak Hour Intersection Capacity Analysis
The capacity analysis for all alternatives in the evening peak hour are summarized in Table 7 and output reports
are attached in Appendix L. All movements operate at LOS D or better except for those discussed below.
Alternative A
The Main Street westbound left onto West Street operates at LOS E in Alternative A conditions though SimTraffic
queues show similar queuing compared to existing conditions.
All movements operate at or under capacity at State Street/New South Street, though a majority of the
movements operate at LOS E or F. Introducing phase separation is likely the primary reason for the degradation
of operations for all vehicular movements except the New South Street northbound right turn and the State Street
southbound right turn. While these vehicular movements see degradation, it is important to emphasize that people
walking and biking through the corridor see significant improvements to their facilities with minimal crossing
conflicts and expanded facilities.
Alternative B
All movements at both intersections operate under capacity in Alternative B. The Elm Street eastbound through
movement SimTraffic queue length is almost half of the queue length expected in Alternative A. While the Main
Street westbound left turn operates at LOS E, SimTraffic queueing is consistent when compared to the existing
conditions.
Though all movements except the Main Street westbound through/right, the Main Street eastbound right turn, and
the State Street and New South Street right turns operate at LOS E or F, SimTraffic queueing is consistent when
compared with existing conditions for all movements.
Alternative C
At the West Street/Elm Street intersection, the Main Street westbound left turn operates at LOS F, but similar to
Alternative A and B, the SimTraffic queueing is similar when compared with existing conditions. The Elm Street
eastbound through movement operates at LOS E with significant SimTraffic queueing.
At the State Street/New South Street intersection, the Main Street eastbound left and the Main Street eastbound
through operate at LOS E likely due to the reduced green time allocated to the left turn movements and the
removal of an eastbound through lane.
Alternative D
All movements at the West Street/Elm Street intersection operate at LOS D or better under Alternative D
conditions. At the State Street/New South Street intersection, the Main Street eastbound left turn, the Main Street
westbound left turn, the Main Street westbound through/right turn and the State Street southbound left/through
operate at LOS F. All movements at both intersections operate with a v/c ratio less than 1.00.
Alternatives Comparison
Similar to the morning peak hour, long SimTraffic queue lengths are apparent for the Elm Street eastbound
through movement in all alternatives, including Alternative D which maintains the existing lane configuration. The
degraded performance in Alternatives A, B, and C are likely due to the designation of the right-only lane, and in all
alternatives restricting right turns on red. Alternative B shows significantly reduced queueing when compared to
the other alternatives. Phase separating right turn, restricting right turn on red movements, and the use of lower
cycle lengths improves safety for people using the southern crosswalk and people biking eastbound along Main
Street by removing turning conflicts and reducing pedestrian and bicycle delay.

Pedestrian Facilities and Operations
Pedestrians in all alternatives are served with concurrent phasing similar to existing conditions with additional
protection through phase separation and restricting right turns on red for the eastbound and westbound
movements. Of all crosswalks at both intersections, only the northern crosswalk across State Street operates with
conflicting permissive turning movements, the Main Street eastbound right turn that has less than 30 conflicting
vehicles per hour among all peak hours. The proposed phasing in all alternatives restricts right turns across the
southern crosswalk across New South Street to rectify the existing, non-MUTCD compliant conflict where the
Main Street eastbound right turn to New South Street has a protected movement across the concurrent southern
crosswalk. In relation to the evaluation criteria Crosswalks are short and minimize conflicts, the proposed
geometry and phasing in all alternatives minimizes crosswalk lengths to the extent the approach geometries allow
and implements phasing operations to maximize separation between vulnerable users and conflicting vehicle
movements. The reduction of the crossing distances, as seen in Table 8, for all crosswalks with the tightening of
the geometries, reduces the amount of time people using the crosswalks are exposed within the intersection
which has both safety benefits for pedestrians and operational benefits for vehicles.

*Alternative D crossing distances are estimates as the alternative was not developed geometrically. Distances reflect Alternative A/B/C
conditions plus 11 feet for crosswalks crossing Main Street to account for the additional through lane.
The pedestrian delay experienced at both intersections is less than 45 seconds for all crosswalks in existing
conditions. The longer cycle lengths compared to the existing 110 second cycle length increases pedestrian delay
relative to existing conditions, but LOS E is maintained for all alternatives along all crosswalks and the shortening
of crosswalk shortens the amount of time pedestrians are exposed in the intersection. The added crosswalk
across Elm Street and the removal of the diagonal crosswalk at State Street/New South Street serve pedestrians
in a more traditional and consistent manner, providing more, low to no-conflict crossings across Main Street and
the intersecting roadways. At State Street/New South Street, pedestrians no longer have to cross through the
middle of the intersection between the concurrent Main Street eastbound and westbound left turn movements. At
West Street/Elm Street, it takes 198 seconds to cross from the southwest corner of West Street/Elm Street to the
north side of the intersection via the diagonal crosswalk at State Street/New South Street in existing conditions in
the evening peak hour. The RSA stated that there were observed occurrences of jaywalking across Elm Street.
The proposed western crosswalk provides direct access across Main Street/Elm Street at West Street, taking
approximately 19 second to cross, directly addressing the existing deficiency observed in the RSA.

Bicycle Facilities and Operations
Separated bike lanes are maintained throughout the corridor, improving the LTS from 2 in existing conditions to 1
in the preferred geometries of Alternative A, B, and C. Weaving amongst the bike lane and travel lanes, as
prevalent in existing conditions along the eastbound approach towards New South Street, is eliminated with he
preferred geometry and the only point of conflict between people biking and people driving is when the Main
Street west through/right turn runs concurrently with the northern crosswalk across State Street.. The right-turn
movement is a low volume movement, seeing fewer than 30 vph in all peak hours, and can be further mitigated
through installation of a flashing right arrow alerting drivers of the conflict. Providing separated bike lanes through
these intersections provides a strong connection to Smith College to the west of West Street while providing a
fully connected, continuous facility throughout the entire project corridor.

With the introduction of an additional eastbound travel lane in Alternative D, separated bike lanes cannot be
provided in either direction west of Masonic Street and bicycle facilities essentially stay the same as existing
conditions. Through these intersections, bicycles would have to navigate within the mix of vehicle traffic. While the
geometry of Alternative D help to address some of the vehicular deficiencies of Alternative A, the addition of an
eastbound through lane comes at the expense of separated bike lanes; this removal violates the values and goals
of the project, specifically the goal to Provide safety and access for all and the evaluation criteria that All modes
have separate and dedicated space for travel.
Recommendations
Alternatives A, B, and C presented in this memo represent scenarios which support the project goals and directly
address the existing safety considerations identified in previous assessments. Operationally, the alternatives
would generally serve vehicles at similar levels with the potential for increased delay and queues in some
locations compared with existing conditions. Any impact to vehicular operations would be balanced by
incorporating safety measures that make the intersections more friendly, comfortable, and accessible to all users
for access to downtown Northampton. A few key distinctions should be made:
All alternatives should convert the driveway on the south side of Main Street between the intersections to
be entrance only to remove conflicts resulting from exiting the driveway as discussed in the RSA.
The apparent need identified through this analysis is the need for more data, particularly with respect to
Alternative B and Alternative C. An origin-destination analysis focused on the entering and exiting
vehicles at these two intersections could provide valuable insight in traffic patterns through both
intersections, and provide a basis for refining model simulations and signal timing/phasing plans
developed with them.
In addition to this localized origin-destination study, new traffic counts should be collected throughout the
entire project area to gauge relative changes in traffic patterns due to the COVID-19 pandemic. New
traffic counts are recommended to be collected while Smith College and local schools are in session to
compare with pre-COVID counts.
While Alternative D rectifies some unsafe existing conditions through the introduction of a crosswalk
traversing Elm Street, realigning the diagonal crosswalk at State Street/New South Street, and phase
separating appropriate movements, the additional eastbound through lane precludes installation of
separated bike facilities west of Masonic Street. This does not satisfy the evaluation criteria, All modes
have separated and dedicated space for travel, or support the project goal of Providing safety and access
for all. Furthermore, this alternative does not improve upon existing conditions significantly, especially
with respect to the Elm Street eastbound through vehicle queueing.
Alternative C would require extensive vetting with the city and local stakeholders and would increase the
scope of the project. Should Alternative C advance, further analysis should involve an origin-destination
study within the greater project area to evaluate the impacts to adjacent roadways as a result of closing
the southbound approach of State Street between Center Avenue and Main Street.
Alternative A and Alternative B satisfy project goals by providing dedicated space to all users, shortening
crosswalks, and minimizing conflicts for people walking and biking along Main Street. Proposed phasing
incorporates phase separation and right turn on red restrictions to enhance safety and crossing
experiences for all users, especially bicycles and pedestrians who see little to no conflicts with high-
volume vehicular turning movements. The diagonal crosswalk at State Street/New South Street is
removed and replaced with a shortened crosswalk across the western leg of Main Street, providing a
more traditional and comfortable crosswalk to users that does not operate between two concurrent
turning movements. Furthermore, the addition of the western crosswalk across Elm Street at West Street
30
drastically reduces the amount of time it takes for pedestrians to cross from the south side to the north
side of the intersection and provides a dedicated crossing facility where the RSA observed occurrences of
jaywalking. Alternative A and Alternative B substantially improve the pedestrian and bicycle experience
through these intersections, better connecting Northampton residents to their downtown area with safe
and comfortable facilities.
Toole Design’s preferred alternative is Alternative A/Alternative B due to the improvements to safety for
all users and support of project goals through phasing and geometric changes to the intersections as
discussed throughout this memo.

APPENDIX B: CAPACITY ANALYSIS
METHODOLOGY
Level of Service (LOS) is a performance measure that defines traffic operations based on the average amount of
time a vehicle waits at an intersection. For example, LOS A defines the condition with minimum vehicular traffic
delay, while LOS F represents the condition with significant traffic delay. Table 1 indicates the LOS conditions
based on average delay as defined by the Highway Capacity Manual (HCM).
Table 1. Level of Service Criteria
Level of
Service
Average Stopped Delay at Signalized
Intersections (Seconds/Vehicle)
A 0.0-10.0
B 10.1-20.0
C 20.1-35.0
D 35.1-55.0
E 55.1-80.0
F >80
To compute the LOS and other performance measures, the HCM methodology was used. For signalized
intersections, HCM 2010 methodology cannot be used since signals use standard National Electrical
Manufacturing Association (NEMA) phasing, rather, HCM 2000 methodology was used. Synchro 10 software was
used to apply these methodologies, which allows for engineers to input characteristics such as lane configuration,
traffic volumes, pedestrian/bicycle to vehicle interactions, and peak hour factors. In addition to estimating the
delay and LOS at intersections, Synchro 10 was used to estimate intersection queue lengths. Results were used
to compare traffic operations in alternative conditions.

APPENDIX D: PEDESTRIAN LEVEL OF
SERVICE ANALYSIS
Pedestrian LOS metrics are based solely on delay and are based on the concepts and procedures in the Highway
Capacity Manual (HCM)1. Table 1, an excerpt from the HCM, provides LOS criteria for signalized intersections,
along with pedestrian noncompliance likelihood guidance. When pedestrians experience more than a 30 second
delay, they become impatient, and engage in risk-taking behavior.
Table 1. Pedestrian Level of Service Criteria

Average pedestrian delay represents the average number of pedestrians anticipated to wait at a signal relative to
the average amount of time those pedestrians have to wait. An additional 4 seconds is granted to the pedestrian
effective green time to account for pedestrians who may begin walking a few seconds after the WALK indication
has begun. The average pedestrian delay is therefore calculated with the following equations:

APPENDIX E: LEVEL OF TRAFFIC
STRESS ANALYSIS
Level of traffic stress (LTS) is a planning tool used to quantify the level of traffic stress that a person bicycling is
likely to perceive while riding on any street or path. The analysis correlates traffic stress with the physical and
operational characteristics of roadways and crossings. It is based on the premise that a person’s level of stress on
a bicycle decreases as separation from vehicular traffic increases and as traffic volume and speed decrease. The
result of the analysis is a numerical traffic stress ranking for every block, from the lowest stress (LTS 1) to the
highest stress (LTS 4). The analysis is based on the Mineta Transportation Institute’s1 research on low-stress
bicycling and network connectivity. It uses a weakest link principle to score road segments based on vehicular
speed, volume, curbside use, and bicycle facility width/separation. Figure 1 shows LTS rating when bicycles ride
in mixed traffic and Figure 2 provides ratings when people biking are provided a bike lane or wide shoulder not
adjacent to a parking lane.

APPENDIX H: PEDESTRIAN AND
BICYCLE PHASING DISCUSSION
Two primary phasing options are available for pedestrian traffic control, exclusive phasing and concurrent
phasing. Each phasing option serves pedestrians with varying degrees of separation from conflicting vehicular
turning movements and each reserves their own implications for pedestrian delay.
Bike movements through intersections may be controlled using a number of tools including vehicle signals,
pedestrian signals, or bike signals. In lieu of dedicated bike signals to provide control to the separated bike lanes,
both alternatives described in this memo include directing people biking through the intersection to use pedestrian
signalization with ‘BIKE USE PED SIGNAL’ signs (R9-5). The use of the R9-5 sign is proposed for several
reasons including overall project equipment and maintenance cost, impacts to vehicle delay, and existing
regulations for dedicated bike signals, which are currently undergoing revisions as part of the update to the
MUTCD. In accordance with the 2009 MUTCD, “The R9-5 sign may be used where the crossing of a street by
bicyclists is controlled by pedestrian signal indications.” Though it is not signed as such today, both people
walking and biking use the existing exclusive pedestrian phase to maneuver through the intersection. The
proposed arrangement will clarify and help guide desired behavior. For all approaches, ‘BIKE YIELD TO PED’
signs (R9-6) are proposed to clarify priority for pedestrians over people making turning movements on bikes.
Exclusive Phasing
Exclusive pedestrian phasing stops all vehicular traffic in all directions so people may cross along all crosswalks,
and if programmed, to cross diagonally through the middle of the intersection. This type of signal phasing grants
full separation and full priority to pedestrians where there are no conflicting vehicular turning movements
permitted. Stopping all vehicular movement for the duration of the time required to cross the longest leg or corner-
to-corner distance at an intersection often leads to high delay for both pedestrians and drivers.
Exclusive phasing offers no legal benefits to people biking. However, in practice exclusive pedestrian phasing is
generally used with user discretion regardless of intended use. Today, a mix of behavior is currently observed at
this intersection, with some bicyclists waiting to use the vehicular traffic signals and others using the existing
exclusive pedestrian phase depending on when in the signal cycle they arrive at the intersection.
Concurrent Phasing
Concurrent pedestrian phasing provides pedestrians a WALK signal at the same time as a green light for parallel
vehicular movements. Concurrent phasing typically minimizes the amount of delay both pedestrians and vehicles
experience at an intersection but requires turning vehicles to yield to pedestrians in the parallel crosswalk.
Leading pedestrian intervals (LPIs) provide a timed buffer to pedestrians, typically between 3 and 7 seconds long,
ahead of the concurrent vehicular movement. During the LPI, pedestrians can enter the crosswalk before the
vehicular movement begins, allowing them to establish their presence in the crosswalk ahead of any conflicting
turning movements.
Concurrent signalization offers the ability to formalize shared use of the pedestrian signal for both people walking
and biking. In accordance with the 2009 MUTCD, “the R9-5 sign may be used where the crossing of a street by
bicyclists is controlled by pedestrian signal indications.” In situations where potential conflicts between people
walking across the street and people making turning movements on bikes may be traveling through the same
phase, supplemental ‘BIKES YIELD TO PED’ (R9-6) are suggested to clarify priority for pedestrians over people
making turning movements on bikes.
Shared phasing between people walking and biking as described above also applies to situations where LPIs are
in use. All of the same benefits accrued to people walking with an LPI are similarly transferred to people biking in
this alternative, including reduction in delay and increased intersection visibility.
Dedicated Bike Signals
Bicycle signals are used to both communicate clearly to a defined user group (people biking) and to reduce
conflicts by phase-separating bicycle movements. Bike signals can be especially helpful or even necessary for
locations with contraflow bike movements (for example on two-way separated bike lanes), locations with high
volumes of bike movements, and locations with high volumes of turning vehicles. Dedicated bike signals also offer
the ability to include leading bike intervals (LBIs) through an intersection, which operate similarly to leading
pedestrian intervals.
Bike signal equipment generally includes either an eight-inch circular indication with a required ‘BIKE SIGNAL’
sign (R10-10b) or a signal with dedicated bike faces (through Federal Highway Administration interim approval IA-
16). When bicycle signal faces are used, no conflicting vehicle movements are allowed, including permissive left
turns and right turn on red movements.
While there are many benefits to bike signals depending on context, none of the current phasing alternatives
include use of dedicated bike signals. In lieu of dedicated bike signals to provide control to the separated bike
lanes, both alternatives described in this memo include directing people biking through the intersection to use
pedestrian signalization with ‘BIKE USE PED SIGNAL’ signs (R9-5) for several reasons including overall project
equipment and maintenance cost, impacts to vehicle delay, and existing regulations for dedicated bike signals
which are currently undergoing revisions as part of the update to the MUTCD.

From: Jason DeGray, PE, PTOE; Kristen Braley, EIT
Project: Main Street (Route 9) Complete Streets Design Services
Re: Traffic Operations at Main Street at King Street/Pleasant Street
Toole Design has prepared this technical memorandum to summarize operational considerations at the key
signalized intersection of Main Street at King Street/Pleasant Street as it relates to the conceptual design
progression of the preferred alternative (Alternative 3: three vehicle travel lanes with expanded sidewalks,
separated bike lanes, and angled parking1). It is intended that the information provided in this memorandum be
sufficient to vet the acceptability, tradeoffs, and opportunities associated with traffic signal operational strategies
related to pedestrian, bicycle, and vehicular users and the achievement of project goals.
Project Goals
Considerations for future operational strategies are to be evaluated as they relate to the evaluation criteria of
overall project goals as shown in Table 1.
1 Picture Main Street Story Map (https://storymaps.arcgis.com/stories/4b996c75da2f4aaca58a1f0310424c77)

Table 1. Overall Project Goals and Evaluation Criteria
Goal 1
Provide Safety and
Access for All
Goal 2
Promote a Vibrant and
Attractive Downtown
Goal 3
Create a Functional, Enduring, &
Sustainable Streetscape Evaluation Criteria Crosswalks are short and
minimize conflicts
Businesses have sidewalk space
for outdoor dining and commerce
Space for commercial loading is
defined and convenient
All modes have separate
and dedicated space for
travel
On-street vehicle parking is
preserved
Delay for people driving and taking
transit on Main Street is minimized
All sidewalks provide at
minimum 5 feet clear space
Space for art, seating, civic
gatherings, and other amenities is
provided
Delay for people walking and
biking on Main Street is minimized
Space for accessible
parking is provided on every
block
A diversity of business, customer,
and civic needs are met Existing trees are preserved
Emergency vehicle access
is preserved - Space for new trees and green
infrastructure is provided
- - Snow management and removal
operations are considered
At the intersection level, the application of the evaluation criteria offers guidance of how to balance operational
needs with the ability to meet project goals. This memorandum provides analyses related to the experience of
modal users (pedestrians, bicycles, vehicles) at Main Street at King Street/Pleasant Street in terms of safety,
delay, and experience as metrics which are directly applicable to some of the project’s evaluation criteria. Other
criteria however cannot be effectively measured at the intersection level, for example, the criteria of All modes
having separate and dedicated space for travel speaks to broader network connectivity and the potential for future
use. As a network is only as strong as its weakest link, it is important to recognize that consideration must be
given in the evaluation of intersection level analyses to the ramifications to broader network level considerations.
For instance, the decision to maintain an additional travel lane for vehicular capacity purposes may appear
warranted to satisfy the evaluation criteria of delay for people driving and taking transit on Main Street is
minimized, but it could easily have an exceedingly detrimental effect on providing dedicated space for travel for all
users. In reviewing this memorandum, it is important to keep the safety, economic, and sustainability goals of the
greater project scope at the forefront while evaluating the concentrated, intersection-level analysis.
Existing Conditions
Main Street at King Street/Pleasant Street is a four leg, fully actuated, signalized intersection towards the eastern
end of the Main Street project area. King Street (Route 5) and Pleasant Street (Route 5 and Route 9) act as
primary north-south routes through Northampton connecting the downtown area to Interstate 91. The southbound
approach of King Street, the northbound approach of Pleasant Street, and the eastbound approach of Main Street
consist of an exclusive left-turn lane, through lane, and right-turn lane. The westbound approach of Main Street
consists of an exclusive left-turn lane and a wide lane that is generally utilized by vehicles as two separate
3
unmarked lanes that operate as a through lane and a shared through/right-turn lane2. For existing conditions
analysis, the intersection is modeled as it predominately operates, as two separate lanes. Marked crosswalks with
curb ramps and flashing-hand indications are provided across all approaches. There are no bicycle facilities
provided at the intersection or along the intersection approaches. All corners of the intersection have “No Right on
Red” signage.
The Main Street at King Street/Pleasant Street cycle length is 141 seconds with the signal phasing represented in
Figure 1. Phasing includes a protected/permitted eastbound and westbound left turns, an exclusive pedestrian
phase, and protected/permitted northbound and southbound left turns. The exclusive pedestrian phase must be
actuated by a person walking or biking.
Figure 1. Main Street at King Street/Pleasant Street Phasing Diagram
Traffic Counts
Traffic volume data were collected to analyze vehicular traffic, pedestrian activity, and bicycle usage throughout
the study area. Turning movement counts (TMCs) were collected on Wednesday, May 1, 2019 from 7:00 am to
9:00 am and from 3:00 pm to 7:00 pm. At Main Street at King Street/Pleasant Street, the intersection peak hour is
from 8:00 am to 9:00 am and the evening peak hour is from 4:00 pm to 5:00 pm. Analysis determined the network
peak hour, including all unsignalized and signalized intersections in the greater project scope, is from 8:00 am to
9:00 am on weekday mornings and 4:45 pm to 5:45 pm on weekday evening as indicated in Table 2. The network
peak hour was used in evaluation of Main Street at King Street/Pleasant Street to achieve consistent vehicular
conditions throughout the corridor.

Pedestrian Facilities and Operations
Pedestrian LOS metrics are based solely on delay and the concepts and procedures in the Highway Capacity
Manual (HCM)3. Table 4, an excerpt from the HCM, provides LOS criteria for signalized intersections, along with
pedestrian noncompliance likelihood guidance. When pedestrians experience more than a 30 second delay, they
become impatient, and are more likely to engage in risk-taking behavior. Average pedestrian delay represents the
average number of pedestrians anticipated to wait at a signal relative to the average amount of time those
pedestrians have to wait.

People walking through Main Street at King Street/Pleasant Street are served with an exclusive pedestrian phase.
In existing conditions, pedestrians are allotted a 31 second exclusive pedestrian phase within the intersection’s
141 second cycle and therefore experience an approximate 60 second average delay per the equations below.
An additional 4 seconds was granted to the pedestrian effective green time to account for pedestrians who may
begin walking a few seconds after the WALK indication has begun. As such, the pedestrian delay is a
conservative estimate and is 67 seconds for people that will not begin their crossing if they miss the initiation of
the WALK indication. An approximate 60 second average pedestrian delay is categorized as an LOS E and a 67
second average delay is categorized as an LOS F (Table 4). An LOS E indicates that the amount of time a
pedestrian may have to wait for a designated WALK indication at Main Street at King Street/Pleasant Street may
exceed pedestrian tolerance levels and result in a high likelihood of noncompliance.

The existing signal timings provide pedestrians a 24 second pedestrian clearance time, enough time to cross the
longest crosswalk: the 85-foot eastern crosswalk (Figure 3). The longest diagonal crossing, from the northwest
corner to the southeast corner, is approximately 130 feet, calling for a 37 second pedestrian clearance interval for
a person walking 3.5 feet per second per the Manual on Uniform Traffic Control Devices (MUTCD)4. The other
diagonal crossing, from the southwest corner to the northeast corner, is approximately 100 feet long and calls for
a 28 second pedestrian clearance interval. Though pedestrians were observed crossing the intersection
diagonally during the Road Safety Audit, the signal timings are not sufficient for either of the diagonal crossings
and pedestrians should make the crossing along the provided crosswalks in two stages.

If a person walking wanted to cross from the northwest corner of the intersection to the southeast corner, it would
take approximately 165 seconds as a two-stage crossing, as depicted in Figure 4 and Table 5.

Though observations of pedestrian noncompliance are not available at this time, the high delay experienced by
pedestrians, especially to cross from one corner of the intersection to another, fosters an unfriendly environment
to people walking in downtown Northampton. The high delay also directly contradicts the project goal to Create a
9
functional, enduring, and sustainable streetscape as supported by the evaluation criteria Delay for people walking
and biking on Main Street is minimized.
Bicycle Facilities and Operations
Within the vicinity of Main Street at King Street/Pleasant Street, there are no bicycle facilities provided along Main
Street and bicycles are expected to use vehicle traffic signals. In reality, a mix of behavior is currently observed
on the street, with some bicyclists waiting to use the vehicular traffic signals and others using the existing
exclusive pedestrian phase depending on when in the signal cycle they arrive at the intersection. A shared use
path connecting to the Manhan Rail Trail, the Norwottuck Rail Trail, and Northampton Bikeway can be accessed
approximately 475 feet west of King Street/Pleasant Street at the Northampton Amtrak Station. A ValleyShare
bikeshare station is located on the northwest corner of the intersection.
Level of traffic stress (LTS) is a planning tool used to quantify the level of traffic stress that a person bicycling is
likely to perceive while riding on any street or path. The analysis correlates traffic stress with the physical and
operational characteristics of roadways and crossings. It is based on the premise that a person’s level of stress on
a bicycle decreases as separation from vehicular traffic increases and as traffic volume and speed decrease. The
result of the analysis is a numerical traffic stress ranking for every block, from the lowest stress (LTS 1) to the
highest stress (LTS 4). The analysis is based on the Mineta Transportation Institute’s5 research on low-stress
bicycling and network connectivity. It uses a weakest link principle to score road segments based on vehicular
speed, volume, curbside use, and bicycle facility width/separation, as shown in Figure 5. As a roadway with two
lanes in each direction, average daily traffic (ADT) greater than 8,000 vehicles per day, and 25 mph speed limit, a
person biking along Main Street experiences a LTS 3.

Safety Analysis
Road Safety Audit
A Road Safety Audit (RSA) was conducted on Thursday, November 21st, 2019 with local and state stakeholders
for the approximately half-mile segment of Main Street between Elm Street/West Street to the west and Market
Street/Hawley Street to the east. As part of the RSA process, participants reviewed crash data throughout the
corridor before a field visit to identify and attribute roadway features and issues to those crashes. The crash
diagram at Main Street at King Street at Pleasant Street is represented in Figure 6 and the accompanying
summary table is attached in Appendix D.
Figure 6. Collision Diagram at Main Street at King Street/Pleasant Street between 2015 and 2017
At Main Street at King Street/Pleasant Street there were 27 crashes in the period analyzed between 2015 and
2017, three of which resulted in non-fatal injuries. The three most frequently reported crash types include:
Sideswipe collisions (10 crashes, 37%);
Rear-end collisions (9 crashes, 33%); and
Angle collisions (3 crashes, 11%).
RSA attendees attributed seven of the ten sideswipe collisions at the intersection to poor pavement marking
conditions that lead to a misunderstanding among drivers regarding appropriate lane assignment and usage when
approaching and navigating the intersection. Specifically, team members said the Main Street eastbound right
lane was often confused with a parking space, and the four sideswipe collisions on the southwest corner involving
right turning vehicles were likely a result.
Roadway and traffic control features that are most often attributed to rear-end collisions, as seen on all legs of the
intersection, include inadequate change intervals, speeding to avoid delay, poor signal visibility, and poor
11
pavement friction. Though none of these features were specifically called out by RSA team members or within
each rear-end collision’s respective crash report, they are the features most commonly associated with rear-end
collisions.
Three of the four angle collisions at the intersection involved eastbound left-turning drivers colliding with
westbound through drivers on Main Street. The crash reports reviewed suggested these collisions occurred
during the permitted left-turn phase of the eastbound and westbound movements when the left-turning vehicle
failed to yield to oncoming traffic. For the eastbound left drivers, it may be difficult to judge gaps in the two-
opposing westbound through and through/right travel lanes.
For people walking at Main Street at King Street/Pleasant Street, audit members noted pedestrians often cross
diagonally from opposite corners of the intersection instead of along marked crosswalks. The pedestrian
clearance time programmed for the exclusive pedestrian phase is inadequate for a diagonal crossing, but RSA
attendees said pedestrians were willing to take the risk to avoid having to wait through the long cycle length for
the next exclusive pedestrian phase.
Furthermore, the RSA notes the narrow sidewalk on the northwest corner of the intersection acts as a pinch point
unable to accommodate the high volumes of pedestrians that queue in that space waiting to cross either adjacent
leg. The northwest corner is also the location of a ValleyShare bikeshare station and a bus stop is located just to
the west of the station. The amenities on this corner and the foot traffic attracted to them often creates congested
walking conditions through the narrowed portion of the sidewalk.
Pedestrian and Bicycle Audit
In January 2016, WalkBoston and MassBike conducted an assessment of pedestrian and bicycle facilities
provided along Main Street between West Street/Elm Street and King Street/Pleasant Street. The assessment
captured pedestrian and bicycle activity while local colleges were in session and while those modes saw their
highest activity throughout the year. Key findings of the report highlight the walkable environment of downtown
Northampton but identify the wide cross section of Main Street as a barrier between the shops, restaurants, and
other amenities on either side of the street. The undefined lanes and poor sight distances due to parked cars was
attributed to the crashes involving pedestrians and rear ends when drivers unexpectedly yield to pedestrians in
crosswalks. Furthermore, the assessment said the wide, undefined travel lanes, angled parking, and complex
intersections make it difficult to navigate Main Street on a bicycle.
At Main Street at King Street/Pleasant Street, the assessment notes one collision with a pedestrian and five with
people bicycling during the crash period analyzed. Of those five collisions with cyclists, four resulted in injury and
one resulted in a fatality involving a westbound left-turning vehicle that failed to yield to an eastbound oncoming
cyclist. Since the time of the assessment, a protected westbound left turn phase has been added to the signal
phasing and timing at the intersection. The assessment, similar to the RSA, notes occurrences of pedestrians
crossing the intersection diagonally despite inadequate pedestrian clearance time to do so. The collision diagram
and summary table for the crash period analyzed in the audit, January 2012 to August 2015, is included in
Appendix E.
Pedestrian and Bicycle Phasing Options
Three primary phasing options were considered at Main Street at King Street/Pleasant Street: exclusive,
concurrent, and New York Style. Each phasing option serves pedestrians with varying degrees of separation from
conflicting vehicular turning movements and each reserves their own implications for pedestrian delay.
Bike movements through intersections may be controlled using a number of tools including vehicle signals,
pedestrian signals, or bike signals. In lieu of dedicated bike signals to provide control to the separated bike lanes,
12
both alternatives described in this memo include directing people biking through the intersection to use pedestrian
signalization with ‘BIKE USE PED SIGNAL’ signs (R9-5). The use of the R9-5 sign is proposed for several
reasons including overall project equipment and maintenance cost, impacts to vehicle delay, and existing
regulations for dedicated bike signals, which are currently undergoing revisions as part of the update to the
MUTCD. In accordance with the 2009 MUTCD, “The R9-5 sign may be used where the crossing of a street by
bicyclists is controlled by pedestrian signal indications.” Though it is not signed as such today, both people
walking and biking use the existing exclusive pedestrian phase to maneuver through the intersection. The
proposed arrangement will clarify and help guide desired behavior. For all approaches, ‘BIKE YIELD TO PED’
signs (R9-6) are proposed to clarify priority for pedestrians over people making turning movements on bikes.
Exclusive Phasing
Exclusive pedestrian phasing stops all vehicular traffic in all directions so people may cross along all crosswalks,
and if programmed, to cross diagonally through the middle of the intersection. This type of signal phasing grants
full separation and full priority to pedestrians where there are no conflicting vehicular turning movements
permitted. Stopping all vehicular movement for the duration of the time required to cross the longest leg or corner-
to-corner distance at an intersection often leads to high delay for both pedestrians and drivers.
Exclusive phasing offers no legal benefits to people biking. However, in practice exclusive pedestrian phasing is
generally used with user discretion regardless of intended use. Today, a mix of behavior is currently observed at
this intersection, with some bicyclists waiting to use the vehicular traffic signals and others using the existing
exclusive pedestrian phase depending on when in the signal cycle they arrive at the intersection.
Concurrent Phasing
Concurrent pedestrian phasing provides pedestrians a WALK signal at the same time as a green light for parallel
vehicular movements. Concurrent phasing typically minimizes the amount of delay both pedestrians and vehicles
experience at an intersection but requires turning vehicles to yield to pedestrians in the parallel crosswalk.
Leading pedestrian intervals (LPIs) provide a timed buffer to pedestrians, typically between 3 and 7 seconds long,
ahead of the concurrent vehicular movement. During the LPI, pedestrians can enter the crosswalk before the
vehicular movement begins, allowing them to establish their presence in the crosswalk ahead of any conflicting
turning movements.
Concurrent signalization offers the ability to formalize shared use of the pedestrian signal for both people walking
and biking. In accordance with the 2009 MUTCD, “the R9-5 sign may be used where the crossing of a street by
bicyclists is controlled by pedestrian signal indications.” In situations where potential conflicts between people
walking across the street and people making turning movements on bikes may be traveling through the same
phase, supplemental ‘BIKES YIELD TO PED’ (R9-6) are suggested to clarify priority for pedestrians over people
making turning movements on bikes.
Shared phasing between people walking and biking as described above also applies to situations where LPIs are
in use. All of the same benefits accrued to people walking with an LPI are similarly transferred to people biking in
this alternative, including reduction in delay and increased intersection visibility.
New York Style Phasing
While traditional concurrent phasing typically permits conflicting movements to turn across a parallel crosswalk,
New York style pedestrian phasing eliminates all vehicle-pedestrian conflicts by introducing turn lanes where not
already provided. Exclusive turn lanes for all turning movements (e.g. no turning movements permitted from the
same lane as a dedicated through lane) allow the signal phasing to be organized such that parallel crosswalks
only run concurrently with through movements while turning movements are restricted to fully protected phases.
Similar to the scenario described above, this phasing style offers the ability to formalize shared use of the
13
pedestrian signal for both people walking and biking for a movement that is fully protected from all motor vehicle
traffic.
While New York style phasing provides the separation benefits of exclusive phasing and the minimized delay
benefits of concurrent phasing, the need for dedicated turn lanes required to accommodate the signal phasing
often has spatial impacts, particularly in regard to which roadway user is allotted that space in a constrained
environment. For example, New York style phasing may provide phasing separation for people walking and biking
at an intersection but may come at the cost of being unable to maintain dedicated bicycle facilities through an
intersection, thus impacting network continuity.
Dedicated Bike Signals
Bicycle signals are used to both communicate clearly to a defined user group (people biking) and to reduce
conflicts by phase-separating bicycle movements. Bike signals can be especially helpful or even necessary for
locations with contraflow bike movements (for example on two-way separated bike lanes), locations with high
volumes of bike movements, and locations with high volumes of turning vehicles. Dedicated bike signals also offer
the ability to include leading bike intervals (LBIs) through an intersection, which operate similarly to leading
pedestrian intervals.
Bike signal equipment generally includes either an eight-inch circular indication with a required ‘BIKE SIGNAL’
sign (R10-10b) or a signal with dedicated bike faces (through Federal Highway Administration interim approval IA-
16). When bicycle signal faces are used, no conflicting vehicle movements are allowed, including permissive left
turns and right turn on red movements.
While there are many benefits to bike signals depending on context, none of the current phasing alternatives
include use of dedicated bike signals. In lieu of dedicated bike signals to provide control to the separated bike
lanes, both alternatives described in this memo include directing people biking through the intersection to use
pedestrian signalization with ‘BIKE USE PED SIGNAL’ signs (R9-5) for several reasons including overall project
equipment and maintenance cost, impacts to vehicle delay, and existing regulations for dedicated bike signals
which are currently undergoing revisions as part of the update to the MUTCD.
Phasing Alternatives
With respect to the preferred corridor alternative, Alternative 3 which maintains three travel lanes through the
corridor, two primary phasing options were primarily explored at Main Street at King Street/Pleasant Street:
Alternative A with concurrent pedestrian phasing and Alternative B with New York style pedestrian phasing.
Discussion on maintaining an exclusive pedestrian phase with the proposed geometry of either alternative is also
included below, Alternatives are evaluated and compared on the basis of vehicular operations, pedestrian and
bicycle operations, and network continuity and connectivity implications.
Alternative A, Concurrent Pedestrian Phasing
The Main Street eastbound and westbound approaches are fed by one general travel lane. As shown in the
preferred design alternative attached in Appendix F, the Main Street eastbound and westbound approaches both
consist of a dedicated left-turn lane and a shared through/right-turn lane. The three-lane approaches consisting of
a left-turn lane, a through lane, and a right-turn lane are maintained for King Street and Pleasant Street.
Separated bike lanes are maintained through the intersection along Main Street.
Guidance from the MassDOT Separated Bike Lane Design Guide (SBLDG) recommends phase separation when
motor vehicle turning volumes across a one-way separated bike facility are greater than 100 vehicles per hour
(vph) turning left across one travel lane (Figure 7). The proposed phasing for Alternative A therefore restricts the
eastbound and westbound left turns to protected-only phasing, as represented in Figure 8. Proposed phasing
14
begins with a 5-second LPI for people walking and biking along Main Street before the eastbound through/right-
turn movements begin. Next, the eastbound and westbound left turns run with the southbound and northbound
right turns. People using the eastern and western crosswalks are provided a WALK phase concurrently with the
southbound and northbound through movements before the final phase providing the southbound and northbound
left turns a protected movement. Right turns on red are restricted in Alternative A to limit the frequency of vehicle
turns across crosswalks with active WALK indications.

6 MassDOT Separated Bike Lane Design Guide, Chapter 6: Signals. (https://www.mass.gov/doc/chapter-6-signals/download)
15
Figure 8. Main Street at King Street/Pleasant Street Alternative A Phasing Diagram
The proposed signal timings prioritize volume-to-capacity ratios for through movements less than one (1) and
maintaining approximate existing queue lengths for turning movements. Capacity analysis and pedestrian delay
implications, as discussed in following sections, were factors in determining the optimal cycle length of 90
seconds for Alternative A phasing.
Alternative B, New York Style Pedestrian Phasing
In Alternative B, a left-turn lane and a right-turn lane fed by a singular travel lane along Main Street are
introduced, as shown in the design alternative attached in Appendix G. The Keing Street and Pleasant Street
approaches maintain three approach lanes in the concept and separated bike lanes are provided along Main
Street through the intersection.
The proposed signal phasing in Alternative B exhibits New York Style concurrent pedestrian phasing, as
represented in Figure 9. Proposed phasing begins with the eastbound and westbound through movements
running concurrently with the northern and southern crosswalks along Main Street. Next, the eastbound and
westbound left turns run with the southbound and northbound right turns. People using the eastern and western
crosswalks are provided a WALK phase concurrently with the southbound and northbound through movements
before the final phase providing the southbound and northbound left turns and eastbound and westbound right
turns a protected movement. As in Alternative A, right turns on red are restricted in Alternative B. In this
alternative, turning movements are never permitted at the same time as parallel crosswalks.
Figure 9. Main Street at King Street/Pleasant Street Phasing Diagram, Alternative B
As with Alternative A, proposed signal timings prioritize volume-to-capacity ratios for through movements less
than one (1) and maintaining approximate existing queue lengths for tuning movements on all approaches.
16
Capacity analysis and pedestrian delay implications, as discussed in following sections, were factors in
determining the optimal cycle length of 90 seconds for Alternative B phasing.
Dismissed Phasing Alternatives
Exclusive pedestrian phasing was considered with the geometries proposed by both alternatives that shorten the
crossing distances. Most notably, in Alternative A, the eastern crosswalk is shortened from 85 feet to
approximately 32 feet and the western crosswalk is shortened from 76 feet to approximately 43 feet; in Alternative
B, the eastern crosswalk is shortened to 42 feet and the western crosswalk is shortened to approximately 53 feet.
The crossing distances among all conditions for all crosswalks are summarized in Table 6.
Table 6. Approximate Length of Crosswalks in Existing and Proposed Alternatives
Existing Conditions (ft) Alternative A (ft) Alternative B (ft)
Eastern Crosswalk 85 32 42
Western Crosswalk 76 43 53
Northern Crosswalk 82 70 77
Southern Crosswalk 67 64 64
Northwest Corner to
Southeast Corner 130 108 120
Northeast Corner to
Southwest Corner 100 88 94
In this preliminary analysis of exclusive pedestrian phasing, the vehicular phasing of both alternatives were
maintained while providing pedestrians an exclusive phase timed to allow people to walk from one corner of the
intersection to the other. Right turns on red are restricted to match existing conditions. In both alternatives in both
peak hours, Synchro’s optimization tools determined the optimal cycle length to be 145 seconds. The tool was
also used to determine optimal splits in each model scenario.
Maintaining the vehicular phasing of either alternative while converting to exclusive pedestrian phasing results in
exhaustive delay and queueing for all movements during both peak hours. The overall intersection operations
have volume-to-capacity ratios over one (1), delays greater than 100 seconds, and levels of service of F in both
alternatives in both peak hours, as summarized in Table 7. All individual movements operate at LOS E or LOS F.
The preliminary Synchro output reports showing vehicular operations for each movement are included in
Appendix H. Due to these preliminary results, exclusive pedestrian phasing was not evaluated further.

The capacity analysis for both alternatives in the morning peak hour are summarized in Table 8 and output
reports are attached in Appendix I. Overall intersection operations remain at LOS D from existing conditions in
Alternative A and Alternative B in the morning peak hour. The Main Street eastbound left turn worsens from LOS
C in existing conditions to LOS F in both alternatives, the Pleasant Street northbound left turn worsens from LOS
C to LOS E in Alternative B, and the King Street southbound left turn worsens from LOS C to LOS F in Alternative
A. In both alternatives, permitted left-turn phases in existing conditions are removed and left turns are only
provided protected movements. Though the reduction in total available green time to execute the left turn
movements is likely a factor in the increase in delay, with the protected-only lefts required by the MassDOT
SBLDG, drivers do not have to judge gaps in opposing traffic as well as be mindful of people in the crosswalk and
separated bike lanes when turning. Shorter cycle lengths also warrant vehicle queues that are consistent or
shorter than experienced under existing conditions despite the longer delays for some movements.

Capacity analysis in the evening peak hour, as summarized in Table 9, shows a worsening of overall intersection
vehicular operations from LOS D in existing conditions to LOS E in Alternative A. Alternative B remains at LOS D.
Similar to the morning peak hour, the Main Street eastbound left turn in both alternatives and the Pleasant Street
northbound left turn in Alternative B worsen from existing conditions, likely due to the removal of permitted left
turn movements and subsequent reduction in available green time. The Main Street eastbound right turn in
Alternative B and the King Street southbound right turn in both alternatives worsen compared to existing
conditions. Restricting the right turns to protected only movements in Alternative B reduces the available green
time for executing the movements. In Alternative A, the Pleasant Street northbound through and the King Street
southbound through both see an increase in LOS E to LOS F though volume-to-capacity ratios remain less than
one. Due to the protected left turn phasing for the eastbound and westbound Main Street movements, less of the
cycle length is available to King Street and Pleasant Street movements.

In both alternatives, all left turn queues are approximately the same length as the length of the turn lanes provided
as shown in the figures provided in Appendix J.
Pedestrian Facilities and Operations
Pedestrians in both alternatives are served with concurrent phasing, Alternative A allowing Main Street right turns
across the northern and southern crosswalks and Alternative B restricting all turning movements across all
crosswalks. In relation to the evaluation criteria Crosswalks are short and minimize conflicts, both alternatives
minimize crosswalk lengths to the extent the Main Street approach geometries allow and implement phasing
operations to maximize separation between vulnerable users and conflicting vehicle movements. The reduction in
the crossing distances in both alternatives reduces the amount of time people using the crosswalks spend
exposed within the intersection which has both safety benefits for pedestrians and operational benefits for
vehicles.
20
By switching to concurrent pedestrian phasing in both alternatives, pedestrians see a reduction in the delay
experienced at Main Street at King Street/Pleasant Street. With exclusive pedestrian phasing in existing
conditions, pedestrians experience a 60 second delay which translates to an LOS E or high likelihood of
noncompliance. In both proposed alternatives, pedestrians experience between 30 and 35 seconds of delay at
any of the crosswalks, or LOS C or LOS D, respectively, which represent a moderate likelihood of noncompliance
(Figure 10). People biking through the Main Street at King Street/Pleasant Street from any roadway approach will
also benefit from the reduction in crossing delay at the intersection through implementation of ‘BIKE USE PED
SIGNAL’ signs (R9-5). The evaluation criteria, Delay for people walking and biking on Main Street is minimized, is
achieved through the concurrent phasing of either alternative and act to Create a Functional, Enduing, &
Sustainable Streetscape as targeted by Goal 3.
Figure 10. Pedestrian Delay in Existing and Proposed Alternative Conditions
It takes people crossing from one corner to another along the northern and eastern crosswalks 165 seconds
under existing geometric and signal timing conditions (Figure 4). In the morning peak hour, it would take a person
walking along the northern and eastern crosswalks 64 seconds to walk from the northwest corner to the
southwest corner with concurrent pedestrian phasing in Alternative A (Figure 11, Table 10) and 61 seconds in
Alternative B (Figure 12, Table 10).

Bicycle Facilities and Operations
In the preferred alternative separated bike lanes are maintained throughout the corridor, improving from LTS 3 in
existing conditions to LTS 1 in proposed conditions. In both phasing alternatives at Main Street at King
Street/Pleasant Street, people biking and following the pedestrian signals benefit from the concurrent pedestrian
phasing that reduces pedestrian delay through implementation of ‘BIKE USE PED SIGNAL’ signs (R9-5). Further
consideration may be given to the use of bicycle signals to accommodate bicycle movements. The use of bicycle
signals may be desired based on applying a consistent typology to signalized intersection approaches and
applicability at other locations. This is a discussion yet to be had with the City, regardless bicycle movements with
bike signals would be phased similar to the proposed pedestrian phasing operations. The use of bicycle signals
would not result in any material changes to bicycle delay to those represented in this memo.
Recommendations
Both of the proposed alternatives presented in this memo represent scenarios which support the project goals
and directly address the existing safety considerations identified in previous assessments. Operationally the
intersection would generally serve vehicles at a similar level of accommodation as the existing conditions by
maintaining volume-to-capacity ratios less than one while greatly improving pedestrian and bicycle
accommodations. A few key distinctions should be made:
The undefined lane use in the westbound direction coupled with protected/permitted left turn movements
from Main Street creates safety concerns for the conflicting movements across the proposed separated
bike facilities which violate MassDOT SBLDG recommendations for phase separating left turns. While
reducing to one travel through lane along this approach will result in no change/minor increases in vehicle
queues, the overall benefit to safety and pedestrian and bicycle operations is substantial.
23
Both Alternatives A and B are predicated upon converting from exclusive pedestrian phasing to
concurrent pedestrian phasing. This concept needs to be explored and vetted with the public and should
be an item of discussion at future engagements.
The decision to advance either Alternative A or B would be based on preference related to the elimination
of any pedestrian/bicycle and vehicular conflicts compared to the loss of streetscape and pedestrian
space needed to accommodate additional through lanes. Given that Alternative A provides concurrent
movements within industry guidelines for minimal ped/bike and vehicular conflicts while affording more
space to the street edge, it is the Toole Design preferred alternative, however Alternative B may also be
considered viable and could become the preferred alternative upon further evaluation and discussion with
stakeholders.

APPENDIX B: CAPACITY ANALYSIS
METHODOLOGY
Level of Service (LOS) is a performance measure that defines traffic operations based on the average amount of
time a vehicle waits at an intersection. For example, LOS A defines the condition with minimum vehicular traffic
delay, while LOS F represents the condition with significant traffic delay. Table 1 indicates the LOS conditions
based on average delay as defined by the Highway Capacity Manual (HCM).
Table 1. Level of Service Criteria
Level of
Service
Average Stopped Delay at Signalized
Intersections (Seconds/Vehicle)
A 0.0-10.0
B 10.1-20.0
C 20.1-35.0
D 35.1-55.0
E 55.1-80.0
F >80
To compute the LOS and other performance measures, the HCM methodology was used. For signalized
intersections, HCM 2010 methodology cannot be used since signals use standard National Electrical
Manufacturing Association (NEMA) phasing, rather, HCM 2000 methodology was used. Synchro 10 software was
used to apply these methodologies, which allows for engineers to input characteristics such as lane configuration,
traffic volumes, pedestrian/bicycle to vehicle interactions, and peak hour factors. In addition to estimating the
delay and LOS at intersections, Synchro 10 was used to estimate intersection queue lengths. Results were used
to compare traffic operations in alternative conditions.

TECHNICAL MEMORANDUM
August 17, 2021
To: Wayne Feiden, FAICP
Director of Planning & Sustainability
City of Northampton
From: Jason DeGray, PE, PTOE; Kristen Braley, EIT
Project: Main Street (Route 9) Complete Streets Design Services
Re: Traffic Operations at Main Street at Market Street/Hawley Street
Toole Design has prepared this technical memorandum to summarize operational considerations at the signalized
intersection of Main Street at Market Street/Hawley Street as it relates to the conceptual design progression of the
preferred alternative (Alternative 3: three vehicle travel lanes with expanded sidewalks, separated bike lanes, and
angled parking1). It is intended that the information provided in this memorandum be sufficient to vet the
acceptability, tradeoffs, and opportunities associated with traffic control strategies related to pedestrian, bicycle
and vehicular users and the achievement of project goals.
Project Goals
Considerations for future operational strategies are to be evaluated as they relate to the evaluation criteria of
overall project goals as shown in Table 1.

operations are considered
At the intersection level, the application of the evaluation criteria offers guidance of how to balance operational
needs with the ability to meet project goals. This memorandum provides analyses related to the experience of
modal users (pedestrians, bicycles, vehicles) at Main Street at Market Street/Hawley Street in terms of safety,
delay, and experience as metrics which are directly applicable to some of the project’s evaluation criteria. Other
criteria however cannot be effectively measured at the intersection level, for example, the criteria of All modes
having separate and dedicated space for travel speaks to broader network connectivity and the potential for future
use. As a network is only as strong as its weakest link, it is important to recognize that consideration must be
given in the evaluation of intersection level analyses to the ramifications to broader network level considerations.
For instance, the decision to maintain an additional travel lane for vehicular capacity purposes may appear
warranted to satisfy the evaluation criteria of delay for people driving and taking transit on Main Street is
minimized, but it could easily have an exceedingly detrimental effect on providing dedicated space for travel for all
users. In reviewing this memorandum, it is important to keep the safety, economic, and sustainability goals of the
greater project scope at the forefront while evaluating the concentrated, intersection-level analysis.
Existing Conditions
Main Street at Market Street/Hawley Street is a four leg, fully actuated, signalized intersection at the eastern end
of the Main Street project area. The Market Street southbound approach, the Bridge Street westbound approach,
and the Hawley Street northbound approach consist of general-purpose travel lanes. The Main Street eastbound
approach is marked as an approximate 28-foot general purpose travel lane; field observations saw this approach
operating as a shared left-turn/through lane and a short right-turn lane where parallel parking ends. For existing
operations, the eastbound approach is modeled as it operates, with two approach travel lanes. Marked
3
crosswalks with curb ramps and flashing-hand indications are provided across all approaches. There are no
bicycle facilities provided at the intersection or along the intersection approaches. Right turns on red are restricted
for the eastbound approach.
The Main Street at Market Street/Hawley Street cycle length is 101.5 seconds with the signal phasing represented
in Figure 1. Phasing includes concurrent eastbound and westbound approach movements, an exclusive
pedestrian phase, and concurrent northbound and southbound approach movements. The exclusive pedestrian
phase must be actuated by a person walking or biking.
Figure 1. Main Street at Market Street/Hawley Street Phasing Diagram
Truck Routes
Three bridges carrying Amtrak railroad tracks and the Manhan Rail Trail are located just to the west of the
intersection. The bridges have a low clearance of 11 feet and cannot accommodate oversize vehicles such as
inter-city buses and semitrucks passing beneath. In 2021 so far, there have been three bridge strikes causing
damage to the oversized vehicles and the bridge itself (Figure 2).
Figure 2. Westbound Semitruck Stuck Beneath Bridge After Ignoring Detour Signs, June 202
For westbound oversize vehicles driving along Bridge Street just east of I-91, a truck detour reroutes traffic north
along Damon Road where they can then turn onto King Street (Route 5) to head back towards downtown
4
Northampton and avoid the bridge. If a driver misses the Damon Road/King Street detour, there are additional
signs directing oversize vehicles to turn onto Lincoln Ave and follow reroute signs to rejoin it. Trucks are restricted
and subject to a $300 dollar fine if they miss the Lincoln Avenue detour and attempt to use Day Avenue, Elizabeth
Street, Orchard Street, and Parsons Street. Hawley Street acts as a last escape route for oversize vehicles
approaching the intersection along westbound Bridge Street. Bridge Street westbound oversize vehicles are
directed to turn left to continue south on Hawley Street where they can follow additional signs redirecting them
back to the Damon Road/King Street detour should they want to continue to downtown Northampton. At Market
Street/Hawley Street the wide curb radii make these truck turns possible for those that have missed all detours
ahead of the intersection (Figure 3).

Traffic Counts
Traffic volume data were collected to analyze vehicular traffic, pedestrian activity, and bicycle usage throughout
the study area. Turning movement counts (TMCs) were collected on Wednesday, May 1, 2019 from 7:00 am to
9:00 am and from 3:00 pm to 7:00 pm. At Main Street at Market Street/Hawley Street, the intersection peak hour
is from 8:00 am to 9:00 am and the evening peak hour is from 4:45 pm to 5:45 pm. Analysis determined the
network peak hour, including all unsignalized and signalized intersections in the greater project scope, is from
8:00 am to 9:00 am on weekday mornings and 4:45 pm to 5:45 pm on weekday evenings as indicated in Table 2.
The network peak hour was used in evaluation of Main Street at Market Street/Hawley Street to achieve
consistent vehicular conditions throughout the corridor.

Network 8:00 – 9:00 4:45 – 5:45
Existing traffic volumes for the weekday morning and evening peak hours including pedestrian and bicycle
volumes are included on Figure 4. All raw traffic count data can be found in Appendix A.
Figure 4. Existing (2019) Condition Vehicular (left), Pedestrian (Middle), and Bicycle (Right) Traffic Volumes
Additionally, automatic traffic recorder (ATR) counts were collected throughout the corridor, specifically between
Strong Avenue and Market Street/Hawley Street between April 30, 2019 and May 1, 2019. The average hourly
eastbound and westbound counts from that ATR location are provided in Appendix A.
Vehicular Operations
Vehicle operations including volume-to-capacity (V/C) ratio, delay, level of service (LOS), and queue lengths were
evaluated using Synchro 10 software as outlined in Appendix B and are summarized in Table 3. In both peak
hours, all movements operate at LOS C or better. Synchro 10 outputs are attached in Appendix C.

Pedestrian and Bicycle Facilities and Operations
Pedestrian LOS metrics are based solely on delay and the concepts and procedures in the Highway Capacity
Manual (HCM)2, as outlined in Appendix D. People walking through Main Street at Market Street/Hawley Street
are served with a 25-second exclusive pedestrian phase within the intersection’s 101.5 second cycle. Under
existing conditions, people using the crosswalks at the intersection experience an average pedestrian delay of 44
seconds, or LOS E, just to cross one leg of the intersection. LOS E reflects a high likelihood on noncompliance.
Within the vicinity of Main Street at Market Street/Hawley Street, there are no bicycle facilities provided along
Main Street. A shared use path connecting to the Manhan Rail Trail, the Norwottuck Rail Trail, and Northampton
Bikeway is approximately 150 feet east of Market Street/Hawley Street at the Northampton Amtrak Station. As a
roadway with two lanes in each direction, average daily traffic (ADT) greater than 8,000 vehicles per day, and 25
mph speed limit, a person biking along Main Street experiences an LTS 3, per the metrics outlined in Appendix E.
Safety Analysis
Road Safety Audit
A Road Safety Audit (RSA) was conducted on Thursday, November 21st, 2019 with local and state stakeholders
for the approximately half-mile segment of Main Street/Bridge Street between Elm Street/West Street to the west
and Market Street/Hawley Street to the east. As part of the RSA process, participants reviewed crash data
throughout the corridor before a field visit to identify and attribute roadway features and issues to those crashes.
2 HCM 2000: Highway Capacity Manual. Washington, D.C.: Transport Research Board, 2000.
7
The crash diagram at Main Street at Market Street/Hawley Street is represented in Figure 5 and the
accompanying summary table is attached in Appendix F.
Figure 5. Collision Diagram at Main Street at Market Street/Hawley Street between 2015 and 2017
At Main Street at Market Street/Hawley Street there were 19 crashes in the period analyzed between 2015 and
2017, five of which resulted in non-fatal injuries. The two most frequently reported crash types were angle
collisions (seven crashes, 37%) and rear-end collisions (five crashes, 26%). One crash at the intersection
involved an eastbound bicyclist and a northbound left turning vehicle which resulted in a non-fatal injury.
RSA attendees attributed the seven angle collisions to concurrent vehicle phasing for all movements, though
specifically the northbound and southbound movements due to the skewed approaches and the wide geometry of
the Hawley Street northbound approach. Four of the seven angle collisions were between northbound and
southbound vehicles. These drivers are expected to have difficulty finding gaps in the opposing travel lanes
because of the poor sight lines of opposing travel lanes and difficulty in finding gaps in that traffic as a result.
Team members suggested evaluating the feasibility of providing protected left-turn phasing, narrowing the Hawley
Street approach to better align with the Market Street approach, installing lane tracking pavement markings
through the intersection, and relocating Market Street and Hawley Street signal heads to overhead mast arms to
increase safety for all vehicles.
Roadway and traffic control features that are most often attributed to rear-end collisions, as seen on the
eastbound and westbound approaches of Main Street and Bridge Street, respectively, include inadequate change
intervals, speeding to avoid delay, poor signal visibility, and poor pavement friction. Though none of these
8
features were specifically called out by RSA team members, they are features most commonly associated with
rear-end collisions. Team member noted that the post office approximately 250 feet east of the intersection along
Bridge Street may be a source of some of the rear-end collisions on the eastern leg as it attracts a large number
of trips and because some drivers were observed using the post office’s access points to avoid the Market
Street/Hawley Street intersection. The rear-end collisions on the eastern leg may also be due to the parallel
parking on the south side of Bridge Street where vehicles may stop abruptly to pull into a parking space or to let a
parked vehicle exit their space. RSA recommendations do not specifically address the rear-end collisions.
Additionally, RSA team members noted that the exclusive pedestrian phase timing was not sufficient for people
crossing from one corner of the intersection to the other despite such observed behavior. It was suggested that
either the exclusive pedestrian phase be extended to allow for the diagonal crossings or that concurrent phasing
be evaluated to reduce delay for all users.
Pedestrian and Bicycle Audit
In January 2016, WalkBoston and MassBIke conducted an assessment of pedestrian and bicycle facilities
provided along Main Street between West Street/Elm Street and King Street/Pleasant Street. Though the
assessment did not include the intersection of Market Street/Hawley Street, crash data from the Northampton
Police Department for crashes occurring between January 2012 and August 2015 was provided in the report.
Within that period, ten crashes were reported, two of two of which resulted in non-fatal injuries. There are no
distinct crash patterns at the intersection in this data set though there are two occurrences of collisions between
northbound and southbound vehicles consistent with the data collected for the RSA. The collision diagram and
summary table for the crash period analyzed in the audit is included in Appendix G.
Traffic Control and Phasing Alternatives
Three options were evaluated for implementation at Market Street/Hawley Street: concurrent pedestrian and
vehicular phasing, concurrent pedestrian phasing with split vehicular phasing, and removing signalization. All
options were developed with the crash patterns between northbound and southbound vehicles and pedestrian
phasing options at the forefront of considerations. Discussion of the characteristics of the different pedestrian
phasing options and bicycle signalization is included in Appendix H. The Main Street eastbound and westbound
approaches are fed by one general travel lane as shown in the preferred design alternative attached in Appendix
I.
Alternative A, Concurrent Pedestrian and Vehicular Phasing
In Alternative A, the existing concurrent vehicular phasing is maintained, and the exclusive pedestrian phase is
removed and replaced with concurrent pedestrian phasing to be consistent with proposed phasing options at
other signalized intersection in the study area (Figure 6). . Switching to concurrent pedestrian phasing reduces
the delay pedestrians experience at the intersection and reallocates the time previously dedicated to the exclusive
pedestrian phase to keeping vehicles moving throughout a cycle. Maintaining the concurrent vehicular phasing
does not address the northbound-southbound vehicle conflicts as apparent in the RSA. Though some geometric
changes and improving visibility through updated signal equipment may mitigate some of the conflict, this
alternative fails to directly address the conflicts between those movements.

The proposed signal timings maintains volume-to-capacity ratios less than one for all approaches. Capacity
analysis and pedestrian delay implications, as discussed in following sections, were factors in determining the
optimal cycle length of 70 seconds for Alternative A phasing.
Alternative B, Concurrent Pedestrian Phasing and Split Vehicular Phasing
The RSA recommended evaluation of protected or protected/permitted left turn phasing. This phasing typically
requires dedicated left turn lanes to facilitate movements. Preliminary evaluation determined that providing a left-
turn lane is not feasible on the Main Street eastbound, Bridge Street westbound, or Market Street southbound
approaches and was therefore not evaluated further. In lieu of left-turn phasing, Alternative B proposes split
phasing which provides the northbound and southbound approaches their own phases, functionally operating like
protected left turn phasing (Figure 7). Phasing begins with an LPI for the northern and southern crosswalks before
they run concurrently with the Main Street eastbound approach and the Bridge Street westbound approach. Next,
the Market Street southbound approach runs concurrently with the western crosswalk then the Hawley Street
northbound approach runs concurrently with the eastern crosswalk. Split phasing removes all conflicts between
the northbound and southbound approaches that are prevalent with concurrent phasing.

The proposed signal timings maintain volume-to-capacity rations less than one for all approaches. Capacity
analysis and pedestrian delay implications, as discussed in following sections, were factors in determining the
optimal cycle length of 100 seconds for Alternative B phasing.
10
Alternative C, Unsignalized
A signal warrant analysis was conducted at Market Street/Hawley Street to determine if the signal was still
warranted with traffic volumes at the intersection. Traffic signal warrant analysis follows the methodology of
Chapter 4C, Traffic Control Signal Need Studies from the 2009 Manual on Uniform Traffic Control Devices
(MUTCD). The 2009 MUTCD recommends that one or more traffic signal warrants are satisfied to justify the
installation of a traffic signal, though installation is not required based on satisfaction. Per MassDOT guidelines,
the Eight-Hour Vehicular Volume warrant must be satisfied to justify signal installation. The following outlines the
intent of each signal warrant and whether it is applicable and was evaluated at the intersection:
Warrant 1, Eight Hour Vehicular Volume – Satisfaction of this warrant indicates that a high volume of
intersecting traffic from the major street approaches likely causes excessive delay or conflict to the minor
street approach. The Eight Hour Vehicular Volume warrant is not applicable at Market Street/Hawley
Street because eight hours of traffic counts are not available.
Warrant 2, Four Hour Vehicular Volume – The warrant is satisfied when large approach volumes from
both the major and minor roadways create excessive conflict at their intersection. This warrant is
applicable and was evaluated.
Warrant 3, Peak Hour – The Peak Hour warrant is satisfied where there is excessive delay or conflict
between high approach volumes from minor and major roadway approaches, but it may only be applied in
“unusual cases, such as office complexes, manufacturing plants, industrial complexes, or high-occupancy
vehicle facilities that attract or discharge large numbers of vehicles over a short time.”3 The intersection is
not applicable because the “unusual cases” clause of the warrant does not apply here.
Warrant 4, Pedestrian Volume – The warrant is applicable where pedestrians experience excessive
delay attempting to cross the major street. Pedestrian counts are available at the intersection making the
warrant applicable and able to be evaluated.
Warrant 5, School Crossing – This warrant is evaluated when the presence of crossing school children
is the major factor for consideration of a signal. The warrant is not being considered due crossing school
children and is therefore not applicable.
Warrant 6, Coordinated Signal System – The warrant is applicable where signalizing a currently
unsignalized intersection within a coordinated system will help to maintain proper platooning of vehicles.
None of the immediately surrounding traffic signals are coordinated and platooning is not a primary
reason for the signal at the intersection, making the warrant not applicable.
Warrant 7, Crash Experience – The Crash Experience warrant is evaluated when installing a traffic
signal may reduce the severity and frequency of recorded crashes. The warrant is not applicable at the
intersection because it is already signalized and crashes occurring are not due to the intersection being
unsignalized. It is expected that this warrant was a factor in initial consideration for signal installation
when the intersection was unsignalized.
Warrant 8, Roadway Network – Evaluation of this warrant is typically provoked by the need to
concentrate and organize traffic patterns within a network. Hawley Street is a local roadway making this
warrant not applicable.
Warrant 9, Intersection Near a Grade Crossing – The Intersection Near a Grade Crossing warrant is
evaluated when all other warrants are not applicable but the proximity to a grade crossing is the primary
3 MUTCD, Section 4C.04 Warrant 3, Peak Hour, Paragraph 2. (https://mutcd.fhwa.dot.gov/htm/2009/part4/part4c.htm)
11
reason for consideration. There are no grade crossings at the intersection making the warrant not
applicable.
Of the nine signal warrants, the Four-Hour Vehicular Volume warrant and the Pedestrian Volume warrant are
applicable and were evaluated with available data. Analysis determined that neither of the warrants are satisfied
with the 2019 data. The traffic signal warrant workbook is provided in Appendix J showing evaluation of these
warrants.
The available count hours and projected count hours were evaluated under Eight-Hour Vehicular Volume warrant
conditions to confirm that the warrant would likely not be satisfied if more count hours were available. Projected
counts hours were generated using automatic traffic recording information that was used to identify proportions of
count hours relative to the peak hours. Those proportions were determined for 6:00am, 9:00am to 2:00pm, and
7:00pm and used to generate volumes relative to the turning movement counts available for each peak hour.
Though the network peak hour is from 4:45pm to 5:45pm, the count hour beginning at 5:00pm was used so
relative volumes by hour could be generated.
To satisfy Condition A, the total major street approach volumes must exceed 500 vph while the highest-volume
side-street approach must exceed 150 vph. To satisfy Condition B, the total major street approach volumes must
exceed 750 vph and the highest-volume side-street approach must exceed 75 vph4. With the available and
projected count hours, only seven hours surpass the threshold conditions needed to satisfy the warrant (Table 4).

Without satisfaction of any of the warrants evaluated, capacity analysis was conducted for an alternative that
evaluates the feasibility of removing the existing signal equipment and making it a two-way, stop-controlled
intersection. Without signalization, the northbound and southbound approaches are not guaranteed clear and
13
dedicated gaps in traffic and must navigate crossing or entering vehicular and bicycle traffic in both directions
while being cognizant of people walking along all crosswalks.
Alternative Evaluation
Vehicular Operations
The capacity analysis for all alternatives in the morning peak hour is summarized in Table 6 and output reports
are attached in Appendix K. Overall intersection operations remain at LOS D or better in both signalized
alternatives which is generally considered acceptable in urban environments. Alternative B sees relatively higher
impacts to delay with a majority of the movements and the overall intersection peak hour operating at LOS D in
both peak hours. The unsignalized Alternative C sees the Market Street eastbound and Bridge Street westbound
approaches operate at LOS A with little delay while the Hawley Street northbound and Market Street southbound
approaches see a large increase in delay relative to existing conditions in both peak hours. The Market Street
southbound approach in both peak hours and the Hawley Street northbound approach in the evening peak hour
are overcapacity with each of their respective volume-to-capacity ratios exceeding one.
In Alternative A, queue lengths for the eastbound and westbound approaches are greater than exiting conditions
in the morning peak hour and similar to or shorter in the evening peak hour. In Alternative B, the eastbound and
westbound queue lengths are longer than in existing conditions in both peak hours. Northbound and southbound
queue lengths are similar to or shorter than existing queue lengths in both signalized alternatives in both peak
hours. The eastbound and westbound queues are essentially eliminated in Alternative C while the northbound
and southbound queues increase relatively drastically. Queue length figures are provided in Appendix L.

Pedestrian and Bicycle Facilities and Operations
By switching to concurrent pedestrian phasing in both signalized alternatives, pedestrians see a reduction in the
delay they’d experience at Main Street at Market Street/Hawley Street. With exclusive pedestrian phasing in
existing conditions, pedestrians experience a 44 second delay which translates to an LOS E. In both signalized
proposed alternatives, pedestrians experience between 25 (LOS C) and 43 (LOS E) seconds of delay at any of
the crosswalks (Figure 8). People biking through the Main Street at Market Street/Hawley Street from any
roadway approach also benefit from the reduction in crossing delay at the intersection. The evaluation criteria,
Delay for people walking and biking on Main Street is minimized, is achieved through the concurrent phasing of
both signalized alternatives and acts to Create a Functional, Enduing, & Sustainable Streetscape as targeted by
Goal 3.
Figure 8. Pedestrian Delay in Existing and Proposed Signalized Alternative Conditions
In the unsignalized alternative, the lack of satisfaction of warrant 4, the Pedestrian Volume warrant, suggests that
pedestrians do not experience excessive delay in attempting to cross Main Street, though the delay cannot be
quantified like for the signalized alternatives.
Safety Analysis
The primary constraint at the intersection is the skewed northbound and southbound approaches that create
visibility issues when they operate concurrently in a phasing plan. Alternative A does not address the issues that
persist in the existing conditions phasing by continuing to allow the movements to operate concurrently. Though
new signal equipment with flashing yellow arrows, some geometric changes, and pavement markings guiding
drivers could help to mitigate the visibility issues, these measures are outweighed by the safety issues inherently
caused by concurrent northbound and southbound approaches. Concurrent pedestrian phasing further
complicates the approaches by requiring drivers to judge gaps in oncoming traffic while also being cognizant of
people in the crosswalk. This could be particularly challenging for the southbound approach that would have
limited sight lines of the northeast curb ramp on the north side of the eastern crosswalk. LPIs help to alleviate
those visibility issues by giving time for pedestrians to establish their presence in the crosswalks ahead of any
concurrent vehicular movements.
Alternative B directly addresses the northbound-southbound conflicts with split phasing that separates the
approaches into their own phases, meaning no movements from either of the approaches ever overlap.
Concurrent pedestrian movements therefore only interact with northbound and southbound right turning vehicles
that have relatively clear visibility of the right-adjacent, parallel crosswalks.

While signal warrant analysis determined the signal to not be warranted at Market Street/Hawley Street, signal
removal may result in crashes often seen at unsignalized intersections. Converting to a two-way, stop-controlled
intersection does not alleviate conflicts between the northbound and southbound approaches and other crash
types that may be solved with signalization may become prevalent at the intersection if the signal were to be
removed. Furthermore, near satisfaction (seven of the eight required count hours surpassing condition thresholds)
of the Eight-Hour Vehicular Volume warrant suggests that vehicular volumes may satisfy the warrant if more data,
not projected data, were available.
Recommendations
The proposed signalized and unsignalized alternatives presented in this memo represent scenarios which support
the project goals and directly address the existing safety considerations identified in previous assessments.
Operationally, the intersection would generally serve vehicles at a similar level of accommodation as the existing
conditions in the signalized alternatives while maintaining or improving pedestrian and bicycle accommodations.
A few key distinctions should be made:
The concurrent northbound and southbound movements have difficult sight lines of the opposing
approach and crash data shows high prevalence of conflicts between those movements.
The signalized A and B alternatives are predicated upon converting from exclusive pedestrian phasing to
concurrent pedestrian phasing. This concept needs to be explored and vetted with the public and should
be an item of discussion at future engagements.
In Alternative A, implementing concurrent pedestrian phasing reduces delay to people walking and biking
through the intersection but may further aggravate those safety concerns between the northbound and
southbound movements. The same concerns are not prevalent in Alternative B due to the introduction of
split phasing where concurrent eastern and western crosswalks only interact with right-turning vehicles.
Based on available and projected data and evaluated signal warrants, a traffic signal is not warranted at
the intersection. The initial intent and justification for signal installation is unknown though it is suspected
that crash patterns may have been a factor in consideration. Furthermore, though the Eight-Hour
Vehicular Volume warrant is not satisfied, analysis was conducted with a combination of available and
projected data which nearly satisfies the warrant. This near satisfaction in addition to the benefits of
providing signalized walk indications, potential safety implications that may arise with signal removal,
limiting delay for the side street approaches, and the nuance of the bridge clearance to the west of the
intersection lead Toole Design to not recommend signal removal.

APPENDIX B: CAPACITY ANALYSIS
METHODOLOGY
Level of Service (LOS) is a performance measure that defines traffic operations based on the average amount of
time a vehicle waits at an intersection. For example, LOS A defines the condition with minimum vehicular traffic
delay, while LOS F represents the condition with significant traffic delay. Table 1 indicates the LOS conditions
based on average delay as defined by the Highway Capacity Manual (HCM).
Table 1. Level of Service Criteria
Level of
Service
Average Stopped Delay at Signalized
Intersections (Seconds/Vehicle)
A 0.0-10.0
B 10.1-20.0
C 20.1-35.0
D 35.1-55.0
E 55.1-80.0
F >80
To compute the LOS and other performance measures, the HCM methodology was used. For signalized
intersections, HCM 2010 methodology cannot be used since signals use standard National Electrical
Manufacturing Association (NEMA) phasing, rather, HCM 2000 methodology was used. Synchro 10 software was
used to apply these methodologies, which allows for engineers to input characteristics such as lane configuration,
traffic volumes, pedestrian/bicycle to vehicle interactions, and peak hour factors. In addition to estimating the
delay and LOS at intersections, Synchro 10 was used to estimate intersection queue lengths. Results were used
to compare traffic operations in alternative conditions.

APPENDIX D: PEDESTRIAN LEVEL OF
SERVICE ANALYSIS
Pedestrian LOS metrics are based solely on delay and are based on the concepts and procedures in the Highway
Capacity Manual (HCM)1. Table 1, an excerpt from the HCM, provides LOS criteria for signalized intersections,
along with pedestrian noncompliance likelihood guidance. When pedestrians experience more than a 30 second
delay, they become impatient, and engage in risk-taking behavior.
Table 1. Pedestrian Level of Service Criteria
Level of Service Pedestrian Delay (seconds) Likelihood of Noncompliance
A 0.0–10.0 Low
B 10.1–20.0
C 20.1–30.0 Moderate
D 30.1–40.0
E 40.1–60.0 High
F >60.0 Very High

Average pedestrian delay represents the average number of pedestrians anticipated to wait at a signal relative to
the average amount of time those pedestrians have to wait. An additional 4 seconds is granted to the pedestrian
effective green time to account for pedestrians who may begin walking a few seconds after the WALK indication
has begun. The average pedestrian delay is therefore calculated with the following equations:

APPENDIX E: LEVEL OF TRAFFIC
STRESS ANALYSIS
Level of traffic stress (LTS) is a planning tool used to quantify the level of traffic stress that a person bicycling is
likely to perceive while riding on any street or path. The analysis correlates traffic stress with the physical and
operational characteristics of roadways and crossings. It is based on the premise that a person’s level of stress on
a bicycle decreases as separation from vehicular traffic increases and as traffic volume and speed decrease. The
result of the analysis is a numerical traffic stress ranking for every block, from the lowest stress (LTS 1) to the
highest stress (LTS 4). The analysis is based on the Mineta Transportation Institute’s2 research on low-stress
bicycling and network connectivity. It uses a weakest link principle to score road segments based on vehicular
speed, volume, curbside use, and bicycle facility width/separation, as shown in Figure 1.
