Road Safety Audit—Route 1A at Everett Street & Clapboardtree Street and
Washington Street at Everett Street, Norwood & Westwood, Massachusetts
Prepared by Vanasse & Associates, Inc.
Background
The combined intersection of Route 1A at Everett Street & Clapboardtree Street and Washington Street at
Everett Street was identified as a high crash location in the Metropolitan Area Planning Council (MAPC)
based on the 2011 Highway Safety Improvement Program (HSIP) cluster data. Improvements at this
intersection, to be constructed as part of the off-site mitigation related to the University Station mixed-use
transit-oriented development to be located off of University Avenue in Westwood, are currently under
review by the MassDOT Highway Division at the 25% Design Level. The MassDOT Highway Division
Traffic and Safety Engineering 25% Design Submission Guidelines require a Road Safety Audit (RSA) be
performed for all project-related high crash locations to identify safety issues and enhancements that may
be implemented in conjunction with the University Station off-site mitigation project, as well as other
measures that could be programmed for implementation by others in the mid-term or long-term
timeframes.
Project Data
The RSA for the subject location was conducted on September 8, 2014 at the Westwood Municipal
Building. The RSA Meeting Agenda is provided in Appendix A. Participating audit team members and
their affiliation are listed in Table 1; team member contact information is provided in Appendix B. For this
modified RSA, team members were encouraged to visit the location prior to the meeting to observe
operations and evaluate potential safety issues, using MassDOT’s Safety Review Prompt list for guidance.
At the meeting, team members were provided with an aerial photograph of the location, and a collision
diagram, summary table, and various bar charts analyzing motor vehicle crashes reported within the three
year review period (2010-2012). This material was reviewed by the team at the meeting in conjunction
with street level views afforded by Google Earth.

Motor vehicle crash data was provided by the Norwood and Westwood Police Departments for the most
recent three year review period available (2010-2012). The data provided includes 38 reported crashes,
with ten (26%) resulting in personal injury, and no reported fatalities. Twenty (53%) of the crashes were
angle or turning movement crashes, ten (27%) were rear-end crashes, five (13%) were sideswipe crashes,
one vehicle struck a deer, and one crash involved a pedestrian or bicycle. Twelve (32%) of the crashes
occurred on wet pavement, and one in snowy conditions. Thirteen (35%) of the crashes occurred during
peak afternoon commuting hours (2 pm to 6 pm), and seven (19%) occurred during the peak morning
commute (6 am to 10 am).
Project Location and Description
Route 1A is typically a four-lane urban minor arterial. North of its intersection with Everett Street and
Clapboardtree Street, it is known as Washington Street and is under Town of Westwood jurisdiction; south
of this intersection, in Norwood, it is known as Upland Road and is under MassDOT Highway Division
jurisdiction, as the Town line bisects the intersection from west to east. Everett Street is a four-lane urban
minor arterial and Clapboardtree Street is a two-lane urban collector, both under Town of Norwood
jurisdiction. The posted speed limit on Route 1A is 40 miles per hour (mph) northbound and 30 mph
southbound; Clapboardtree Street is posted at 30 mph approaching the intersection, and Everett Street is
unposted in the westbound direction. Everett Street intersects Route 1A from the east and Clapboardtree
Street intersects Route 1A from the west to form a four-way intersection under fully-actuated traffic signal
control. Each Route 1A approach consists of an exclusive left turn lane and two through travel lanes. The
Everett Street westbound approach consists of an exclusive left turn lane and a through travel lane. The
Clapboardtree eastbound approach consists of a shared through/left turn lane. The right turns from each
side street are channelized via raised median islands. Median islands are also provided on the Route 1A
approaches to separate directions of travel.
Approximately 100 feet east of Route 1A, Washington Street (a.k.a. Lower Washington) intersects Everett
Street from the south to form a three-legged signalized intersection which operates in conjunction with
Route 1A under a single traffic signal controller. A railroad bridge crosses over Everett Street, between the
two intersections. Washington Street, south of Everett Street, is typically a two-lane urban collector under
Town of Norwood jurisdiction, with a posted speed limit of 30 mph. The Washington Street northbound
approach consists of an exclusive left turn lane and an exclusive right turn lane. The Everett Street
approaches are each comprised of two general purpose travel lanes.
Sidewalks currently exist along both sides of Route 1A north of the intersection, along the west side of
Route 1A south of the intersection, along both sides of Everett Street, along the north side of
Clapboardtree Street, and along both sides of Washington Street south of the intersection. Curb ramps and
a crosswalk are provided across the north leg of the intersection, including the channelized right turn, and
across the Washington Street approach to Everett Street. Curb ramps with no corresponding marked
crosswalk exist across the Clapboardtree Street approach, including the channelized right turn, on the
southeast corner of Route 1A and Everett Street, and on Everett Street opposite Washington Street.

The existing traffic signal phasing provides for protected leading left turns on Route1A northbound and
southbound. Everett Street westbound operates with a protected-permissive left turn to Route 1A
southbound. The lower Washington Street approach is currently allowed to run during both the protected
and permissive portions of the Everett Street westbound movement at Route 1A. Clapboardtree Street runs
concurrently with Everett Street. A concurrent pedestrian phase is provided for crossing the Route 1A
mainline (excluding the channelized right turn) upon pushbutton actuation. No pedestrian signals are
present at the pedestrian crossing of the south leg of Washington Street or at other unmarked crossings
where curb ramps are provided.
A locus map and aerial photograph of the existing conditions are provided as Figure 1 and 2, respectively.

Audit Observations & Potential Safety Enhancements
Observations:
Signal Visibility
It was noted that the mast arm mounted signal
head on Everett Street westbound prior to the
railroad bridge visually blends with the bridge
itself, which is painted green. This could contribute
to rear-end, angle, or turning movement crashes if
drivers are unsure of the signal indications and
proceed without the right of way or brake/stop
unnecessarily when they do have the right of way.
Also in the westbound direction, it was reported that the optically programmed signal indications on the
far side of Route 1A may be visible to drivers on Everett Street beyond the intended limit, which could
allow drivers to see a red indication in the foreground (at lower Washington Street) and a conflicting
green indication beyond, or vice versa. This could lead to rear-end or turning movement crashes and
contribute to red light running.
Optically programmed signal heads are also
present for Everett Street eastbound on the far side
of the railroad bridge. RSA members noted that
eastbound drivers approaching lower Washington
Street may not expect to encounter another
signalized intersection after passing through the
Route 1A intersection; this is exacerbated by the
bridge and optically programmed signals. The
bridge partially obscures the overhead signals and
the optically programmed signals are set so that the
driver does not see the indication until they are too
close to comprehend and react. These issues could
lead to rear-end or turning movement crashes; in
particular, there were eight reported angle crashes
between an eastbound vehicle and a northbound
vehicle, with crash reports noting that a vehicle ran
the red light or the driver was confused.

Washington Street at Everett Street, Norwood & Westwood, Massachusetts

Signal Equipment & Operation
The signal phasing allows the Clapboardtree Street/Everett Street phase (at Route 1A) to run
concurrently with the northbound Washington Street phase. This scheme allows Washington Street
northbound traffic to proceed through the Route 1A intersection and minimizes queuing on Everett
Street between Route 1A and Washington Street. However, drivers from Clapboardtree Street may
assume they will have a green light to continue on Everett Street eastbound, past Washington Street,
when that signal is red to allow the Washington Street northbound movement. This is likely the cause of
a majority of the rear-end and angle crashes reported at this location.
Red-light running was cited as a concern. This could be attributed to a number of factors, including
inadequate change and clearance intervals, aggressive driver behavior exacerbated by long delays,
vehicles becoming trapped in the intersection due to the concurrent side street phasing, placement of
overhead signal equipment, or inadequate visibility of optically programmed signal heads (as
mentioned above).
Queuing
It was noted that Route 1A southbound left turn queues often spill outside the exclusive left turn lane
into the adjacent through lane, which causes through drivers to move over to the right-most through lane
to avoid. No reported crashes were directly attributable to this condition, however it adds to the long
delays.
Route 1A southbound queues often extend past Marshall Street, prohibiting vehicles from entering or
departing the side street during peak hours and occasionally causing northbound traffic in the left lane to
back up to Everett Street behind a vehicle waiting to turn left into Marshall Street. This condition
introduces the potential for angle crashes. It should be noted that crashes reported at the intersection of
Route 1A and Marshall Street were not included in the study.
Geometry
It was noted that the horizontal curve in Route 1A
southbound approaching the intersection obscures
the advance view of the traffic signals; trees on the
inside of the curve exacerbate this issue. This
could be a factor in rear-end crashes if drivers
encounter stopped vehicles before recognizing that
the signals are red.

Washington Street at Everett Street, Norwood & Westwood, Massachusetts

Striping & Signing
The Everett Street westbound approach lacks pavement markings and signing to designate the intended
lane use. A number of related occurrences were described, including vehicles turning left from both
approach lanes at Route 1A, and vehicles attempting to proceed through to Clapboardtree Street from
the left lane. This condition is exacerbated by the misalignment of the through lane from Everett Street
westbound to Clapboardtree Street, which is offset to accommodate the exclusive left turn lane. This
likely contributes to angle and sideswipe crashes (crash #7, for example) as drivers turning from the left
lane would not expect a vehicle in the adjacent lane to be turning left as well and, similarly, drivers in
the right lane would not expect a vehicle in the left lane to continue through. Also, through vehicles
must veer left somewhat through the intersection to continue through during the concurrent side street
phase.
It was noted that there is a general lack of guide signs and route marker signs approaching the
intersection, though this is unlikely to be a significant factor in reported crashes.
The angle of entry to Route 1A northbound from
the channelized right turn from Everett Street
makes it appear as though the turning roadway has
a dedicated lane entering Route 1A. Also, no
YIELD sign or yield line pavement marking is
present. This could be a factor in sideswipe crashes
at that location as drivers approaching from Everett
Street may mistakenly believe they have the right
of way.
Vehicles have been observed to make a right turn
on red from Route 1A northbound where, during
certain phases, they immediately encounter a red
light. This could lead to rear-end crashes.
However, a “No Turn on Red” sign is present on
the approach, but the visibility/placement is poor.
It was suggested that the stop line on the Route 1A southbound approach is set back too far and that
moving it forward could serve to increase storage in the short left turn lane.

Washington Street at Everett Street, Norwood & Westwood, Massachusetts

Pedestrian Accommodation
There is significant pedestrian activity due to the proximity of Xaverian Brothers high school on
Clapboardtree Street and MBTA bus stops on Route 1A southbound, just prior to Marshall Street, and
northbound, opposite Marshall Street. One pedestrian crash was reported during the study period, in
which a driver later cited for operating under the influence struck a pedestrian on the grass shoulder of
Route 1A northbound, just south of the intersection.
It was noted that pedestrian access is generally poor due to limited pedestrian signals and crosswalks,
and non-compliant curb ramps. The only signalized crossing is across the northern leg of Route 1A;
however the pedestrian signal heads do not meet current standards. Crosswalks are only present across
the northern leg of Route 1A and across lower Washington Street. However, the record signal permit
also shows a striped crosswalk across Clapboardtree Street, which does not currently exist; noncompliant curb ramps are present for this crossing.
It was noted that visibility to pedestrians under the railroad bridge is compromised by shadows.
The sidewalk from the south leg of Washington Street continues under the railroad bridge and around
the corner to Route 1A, where it terminates abruptly, with no crosswalk provided.
Bicycle Accommodation
Shoulders on all approaches are inadequate for bicycle travel, though no bicycle crashes were reported.
The traffic signal presently has no bicycle detection.
Pavement Condition
It was observed that a bump is created at the brick paver crosswalk across the north leg of the
intersection. This appears to be caused by the pavement settling immediately adjacent to the flush
granite curb which borders the pavers. The flush granite curb appears to be in good condition and still
retains the pavers adequately.
It was noted that the pavement becomes slippery in winter, particularly the Everett Street westbound
approach. This could be a contributing factor in numerous crash types, most notably rear-ends, if
drivers misjudge braking distance given the conditions.
There is significant rutting, particularly on the Route 1A approaches to the intersection. Numerous
potholes and utility trench patches also exist on Everett Street, between Route 1A and Washington
Street. These may cause drivers to swerve to avoid and could contribute to sideswipe or angle crashes.

Potential Enhancements:
1. Replace existing backplates with new backplates with fluorescent yellow retroreflective borders for
all signal heads to improve visibility, particularly on Everett Street westbound against the railroad
bridge.
2. Work with bridge owner to paint bridge to provide visually contrasting background for signal
heads.
3. Review visibility limits and adjust all optically programmed signal indications as necessary to
ensure they are not visible beyond their intended limit, particularly Everett Street westbound.
4. Consider alteration and/or horizontal mounting of signal head(s) on far side of bridge for
eastbound traffic to alleviate blocked view of far-side signals by bridge, or other solution to
improve advance signal visibility/recognition.
5. Consider installation of signal ahead (W3-3) or L.E.D. “Red Signal Ahead” warning sign on
west side of bridge (possibly on the bridge itself) to provide advance notification of lower
Washington Street signal.
6. Review placement of optically programmed signal heads and the need for each green, yellow
and red indication to remain optically programmed. This could potentially improve advance
recognition of change and clearance intervals and reduce rear-end crashes caused by vehicles
stopping abruptly.
7. Consider modifications to signal phasing to prohibit the Lower Washington and Clapboardtree
Street phases from occurring simultaneously. This could significantly reduce the number of
rear-end and angle crashes caused by eastbound drivers unexpectedly encountering a red
indication at Washington Street immediately after crossing Route 1A, and possibly reduce the
occurrence of red light running. This change to phasing would likely reduce capacity and
increase delays. Opportunities to compensate for the capacity reduction should be explored and
implemented if feasible, such as a second southbound left turn lane, an additional lane on the
Clapboardtree Street approach and/or an exclusive right turn lane northbound.
8. Consider implementation of flashing yellow arrow operation for the Everett Street approach.
This would allow left turn movements and a protected advance phase, which would be
expected to reduce the incidents of angle and turning movement crashes within the
intersection.
9. Review change/clearance intervals, accounting for approach grades. This will ensure that
vehicles are afforded sufficient time to clear the intersection and could reduce red-light running.
10. Install new mast arms at the far side of the intersection approaches, rather than diagonally in the
middle, to reduce the red signal violations.
11. Provide internal green clearance to clear eastbound vehicles on Everett Street between
Route 1A and lower Washington Street and reduce red-light running and associated crashes.
Page 10

Washington Street at Everett Street, Norwood & Westwood, Massachusetts
Prepared by Vanasse & Associates, Inc.
12. Widen Route1A southbound to extend left turn lane to increase capacity, improve accessibility
to the left turn lane, and reduce potential queue spillover into the adjacent through lane.
13. Review location of STOP line on Route 1A southbound and relocate if possible to increase
storage capacity on approach and to shorten the width of the intersection, hence reducing the
required change and clearance intervals.
14. Install “Do Not Block Intersection” sign and/or pavement markings on Route 1A at Marshall
Street to maintain abutter access and prevent northbound queue backup to Everett Street.
15. Consider addition of a supplemental far left signal head on Route 1A southbound to improve
advance visibility and account for the horizontal curve on approach. This could reduce rearend crashes by providing advance notice to drivers of a red light. However, MassDOT
District 5 Traffic Operations has requested that this not be implemented, since placement of
this signal head to the left of the exclusive left turn lane signal could cause drivers to mistake
this for an advance left turn signal.
16. Install lane use pavement markings and signing on Everett Street westbound to clarify intended
lane use and improve advance decision-making regarding lane assignment. This measure could
reduce angle and sideswipe crashes as vehicles would be less likely to make a conflicting
movement from the wrong lane unexpectedly.
17. Implement maintenance program for pavement markings, considering that the alignment/
configuration of the Everett Street approach contributes to accelerated wear. This could help
reduce all crash types on the Everett Street approach.
18. Install advance street name (“Next Signal Ahead”) signs on Route 1A approaches to aid
drivers in selecting the correct lane in advance of the intersection.
19. Install YIELD sign and YIELD line for the channelized right turn to Route 1A northbound to
define the desired yield point and add dotted edge line across the channelized right turn lane.
20. Relocate “No Turn on Red” sign for Route 1A northbound to improve visibility.
21. Add crosswalks and install pedestrian signals for crossing the south leg of Route 1A,
Clapboardtree Street, and Everett Street at Lower Washington to improve pedestrian
accessibility and connectivity.
22. Review pedestrian signal phasing and pedestrian volumes to determine if exclusive or
concurrent phasing is more appropriate at this location to best balance pedestrian
accessibility/safety and intersection operations.
23. Upgrade curb ramps to provide ADA-compliant pedestrian access.
24. Install lighting under bridge to improve visibility of pedestrians.
25. Widen approach roadways to provide 5-foot wide shoulders for bicycle accommodation.
Page 11

Washington Street at Everett Street, Norwood & Westwood, Massachusetts
Prepared by Vanasse & Associates, Inc.
26. Install bicycle detection and associated signs and pavement markings.
27. Evaluate brick paver crosswalk on Route 1A and repair settled pavement immediately adjacent to
flush granite curb to improve ride quality.
28. Repave the intersection to remove rutting and improve skid resistance, considering a high-friction
pavement mix. This could reduce all crash types during slippery conditions and rear-end crashes
during all road conditions. This measure would also serve to correct potholes and trench patches,
improving ride quality. It should be noted that MassDOT District 5 and the Town of Westwood
have indicated that they do not want a high friction surface treatment applied at this location.
Summary of Road Safety Audit
Potential safety enhancements that were discussed during the RSA meeting and described in the previous
section are summarized in Table 2. For each potential enhancement, an estimate of the safety benefit
(“payoff”), approximate timeframe to implement, and cost are noted; the responsible party recommended
to implement the enhancement is also identified.
Safety payoff estimates are qualitative and categorized as low (<30%), medium (31% to 70%), or high
(>71%). The time frame to implement each enhancement is categorized as short-term (<1 year), mid-term
(1 to 3 years), or long- term (>3 years). The cost estimates are categorized as low (<$10,000), medium
($10,001 to $50,000), or high (>$50,001).
Enhancements where the developer is identified as the responsible agency and marked with an asterisk have
already been incorporated into the 25% Design Plans for improvements at this intersection, to be
constructed as part of the off-site mitigation related to the University Station mixed-use transit-oriented
development to be located off of University Avenue in Westwood, which are currently under review by the
MassDOT Highway Division.
