Background
The Federal Highway Administration defines a Road Safety Audit (RSA) as the formal safety examination
of an existing or future road or intersection by an independent, multidisciplinary team. The purpose of an
RSA is to identify potential safety issues and possible opportunities for safety improvements considering
all roadway users. A Road Safety Audit was scheduled for Route 27 over Route 9 and the Route 27/Route
9 interchange because the area has been identified as high crash location within the Metropolitan Area
Planning Council (MAPC). 25% design plans were submitted in 2011 for the reconstruction of Route 27
over Route 9 (MassDOT File No. 605313), including reconstruction of the bridge and reconfiguration of
the interchange ramps. The project is not currently scheduled on the Boston Region MPO Transportation
Improvement Program (TIP). A project is also under design to reconstruct Route 27 from North Avenue to
the Wayland town line (MassDOT File No. 605034), excluding the Route 9 interchange. 25% design plans
were submitted in 2009 for this project, which is also not currently scheduled on the Boston Region MPO
TIP. The RSA is intended to identify potential short and long term safety improvements that can be made
along Route 27, Route 9 and at the interchange, which can then be implemented through general
maintenance for short term low cost improvements or incorporated into the planned reconstruction project
for long term improvements. It is important to ensure that the two Route 27 projects are coordinated to
maximize and prioritize improvements along the corridor.
Project Description
Route 27 (North Main Street) and Route 9 (Worcester Street) intersect via a modified full cloverleaf
intersection in the Town of Natick, as shown in Figure 1. A structurally deficient bridge carries Route 27
over Route 9. Route 27 intersects Route 135 in the center of Natick approximately 1.4 miles south of
Route 9, and connects Natick to Wayland to the north and to Sherborn and Medfield to the south. Route 9
is a significant east-west arterial roadway, connecting the Metro West towns of Framingham and Natick
to the Mass Pike (I-90), I-95/Route 128, and Boston.
Route 9 and the majority of the interchange ramps are under State jurisdiction. Route 9 is classified as a
Principal Arterial. Route 27 is classified as an Urban Principal Arterial, and is state-owned within the
immediate vicinity of the interchange but under Town jurisdiction both north and south of the
interchange. The ramp in the northwest quadrant of the interchange is under Town jurisdiction, likely
because it provides a connection to Lake Shore Road, a town-owned road.
Land use in the area is primarily commercial along Route 9 and within the vicinity of the interchange, and
residential outside of the interchange limits both north and south on Route 27. Notable commercial
properties include the 9/27 Plaza in the northeast quadrant of the interchange, which includes a Stop &
Shop grocery store. A Valvoline instant oil change shop is located immediately adjacent to the on-ramp in
the northwest quadrant of the interchange. Sunnyside Plaza is west of Valvoline, and a driveway
connecting Route 9 to Sunnyside Plaza and to Lake Shore Road separates the two properties.
The south side of Route 9 includes an abandoned gas station and an auto dealership prior to the off-ramp
in the southwest quadrant of the interchange, and a Midas repair shop and a U-Haul rental shop following
the on-ramp in the southeast quadrant of the interchange.

Road Safety Audit—Route 27 over Route 9 and Interchange—Natick, MA
Prepared by BETA Group, Inc.
As previously discussed, the interchange is a modified cloverleaf, with additional access points atypical of
a cloverleaf interchange. A discussion of ramps by quadrant follows.
Northeast Quadrant:
Route 9 Westbound off-ramp to Route 27 Northbound
Route 27 Northbound on-ramp to Route 9 Westbound
Route 9 features a westbound deceleration lane approximately 250 feet in length along the frontage of the
Stop&Shop. No direct access is provided from Route 9 to Stop&Shop or the 9/27 Plaza. The off-ramp
from Route 9 westbound to Route 27 northbound continues along the edge of the 9/27 Plaza and has a
right-in/right-out driveway with the plaza, with the entrance and exit driveways divided by a triangular
channelizing median. Plaza patrons from Route 9 west would use this driveway to enter the plaza, while
patrons leaving the plaza bound for Route 27 north would use this driveway to exit. All other plaza traffic
enters and exits via a signalized intersection with Route 27 north of the interchange ramps.
Route 9 WB off-ramp to Route 27 NB at 9/27 Plaza Entrance
The off-ramp continues past the plaza driveway and ends under STOP control at Route 27 northbound.
The on-ramp from Route 27 northbound to Route 9 westbound is a more typical loop ramp, but with a
sharp entry curve, a tangent section, and a sharp curve prior to a STOP controlled entry to Route 9. All
ramps entering Route 9 from Route 27 are under STOP control due to the sharp entry angles and lack of
acceleration and deceleration lanes.
A sidewalk is provided along the north side of Route 9, and crosswalks are provided across both ramps
with adjacent wheelchair ramps. A pedestrian access to the 9/27 Plaza is provided adjacent to the
westbound deceleration lane approximately 180 feet in advance of the ramp exit gore.

Southeast Quadrant:
Route 9 Eastbound off-ramp to Route 27 Northbound
Route 27 Northbound on-ramp to Route 9 Eastbound
The off-ramp from Route 9 eastbound to Route 27 northbound and the on-ramp from Route 27
northbound to Route 9 eastbound most closely follow the geometry of a typical cloverleaf intersection.
One exception is a driveway to C&T Paint & Wallpaper, which has a direct connection to the on-ramp
from Route 27 northbound to Route 9 eastbound. A scored concrete median separates the opposing travel
directions of the adjacent ramps, but allows vehicles to turn in and out of the paint store driveway to and
from the off-ramp, requiring them to cross the on-ramp. The paint store has no other access to Route 9 or
Route 27.
Route 27 NB on-ramp to Route 9 EB at Paint Store driveway
The on-ramp to Route 9 eastbound is under STOP control, while the off-ramp to Route 27 northbound is
under yield control. Eastbound vehicles on Route 9 intending to exit to Route 27 northbound must merge
right to enter the deceleration lane, which also serves as the acceleration lane for the ramp from Route 27
southbound onto Route 9 eastbound. This combined acceleration/deceleration lane creates a weaving area
of approximately 350 feet between the two ramps. A bus turnout is adjacent to the acceleration/
deceleration lane, but is not presently utilized.
A sidewalk is provided along the south side of Route 9, and crosswalks are provided across both ramps
with adjacent wheelchair ramps. No sidewalks are provided along the east side of Route 27 at the ramps;
however, a worn path along the edge of roadway indicates pedestrian usage. No crosswalks are provided
across the ramps at Route 27.

Southwest Quadrant:
Route 9 Eastbound off-ramp to Route 27 Southbound
Route 27 Southbound on-ramp to Route 9 Eastbound
The ramps in this quadrant feature a tangent section which introduces some lateral separation between the
ramps and the Route 27 overpass, and in turn between the two loop ramps on opposite sides of the bridge,
which creates the aforementioned 350 foot weaving area. Route 27 southbound features a right turn lane
approximately 150 feet in length for the on-ramp to Route 9 eastbound, and the ramp features a sharp
entry curve, followed by a tangent section and a loop ramp, with entry to Route 9 under STOP control. A
120 foot deceleration lane is provided on Route 9 eastbound before the off-ramp, which features a sharp
entry curve to the right, a curve to the left, then a tangent section followed by a curve to the right. The
ramp is under yield control at Route 27.
Route 9 EB off-ramp to Route 27 NB
Sidewalks are provided across both Route 27 and Route 9 in this quadrant, and crosswalks are provided at
both the entry and exit to both ramps, with adjacent wheelchair ramps. Ramps along Route 27 do not
include detectable warning panels.
Northwest Quadrant:
Route 9 Westbound off-ramp to Route 27 Southbound
Route 27 Southbound on-ramp to Route 9 Westbound
Lake Shore Road
The ramps in the northwest quadrant of the interchange are the most atypical due to the presence of Lake
Shore Road. Entry from Route 27 southbound to Route 9 westbound is achieved via a long ramp that runs
essentially parallel to Route 27 for 700 feet before a sharp curve to the right and entry to Route 9 under
STOP control. The ramp is intersected by several commercial driveways, by Lake Shore Road, and by a
two-way connector with Route 27. The two-way connector serves two purposes; it allows access from the
Route 9 westbound off-ramp to Route 27 south, and it allows left turns from a short left-turn lane to
access Lake Shore Road. The ramp accommodates two way travel with turns allowed from Lake Shore
Road to a commercial driveway approximately 300 feet north of Lake Shore Road, a segment that
includes the two-way connector to Route 27. Two-way travel separated by a scored concrete median
continues approximately 200 feet south of Lake Shore Road.

Route 27 SB on-ramp to Route 9 WB
(Lake Shore Road on left, two-way connector in distance on right)
Access management in this area is complicated by the Valvoline shop immediately west of the ramp, and
by Sunnyside Plaza west of Valvoline. Valvoline has an entry driveway directly following the on-ramp
from Route 27 southbound, which requires Route 9 traffic to travel across the ramp merge area to access
Valvoline. The only exit from Valvoline is onto the ramp, which requires all traffic to turn right onto the
on-ramp to Route 9 westbound or to turn left across the on-ramp and the scored concrete median.
An access roadway between the entry driveway to Sunnyside Plaza and Lake Shore Road further
complicates access. Vehicles traveling west on Route 9 use this driveway to access Sunnyside Plaza, but
can also cut through the parking area to access Lake Shore Road. Since a connection is provided between
Route 27 and Lake Shore Road via the on-ramp, this also creates a number of secondary access routes
between Route 27 and Route 9 westbound. Vehicles traveling northbound on Route 27 can use the ramp
to the right intended to provide access to Route 9 westbound, or they can turn left through the short twoway connector and access the ramp in the northwest quadrant of the interchange. From there they can
either travel south via the ramp to Route 9 westbound, or turn right onto Lake Shore Road and cut
through the Sunnyside Plaza access driveway to Route 9 westbound. Vehicles traveling south on Route
27 follow the ramp to Route 9, but can either continue along the ramp or turn right on Lake Shore Road
and cut through the Sunnyside Plaza access driveway. It was noted that more aggressive drivers find the
most desirable route amongst these options during times of congestion.
An approximate 200 foot weaving segment is created in advance of the Route 9 westbound off-ramp to
Route 27 southbound, with a lane shared for acceleration from the Route 27 northbound on-ramp and
deceleration for the off-ramp. The off-ramp continues north to Lake Shore Road, where left turns are
allowed, and then to the two-way connector roadway. Vehicles bound for Route 27 southbound turn right
onto the connector and then can turn right onto Route 27 southbound under STOP control. An overhead
flasher is provided at the intersection between the two-way connector and Route 27, although the yellow
indication facing northbound traffic was out on the day of the audit.
A bus stop is provided along Route 9 in front of Sunnyside Plaza, west of the ramps and the access
roadway between the plaza and Valvoline. MWRTA personnel noted that this stop is no longer used due
to concerns of conflicts between slowing buses and accelerating vehicles departing the ramp. Buses
traveling west on Route 9 now stop at the 9/27 Plaza, which requires them to exit and then re-enter Route
9.

A sidewalk is provided along the north side of Route 9, and crosswalks are provided across both ramps
with adjacent wheelchair ramps. A sidewalk is also provided along the west side of the ramp, which
connects to sidewalks on Route 27 north of the ramp.
Route 27 (North Main Street) at 9/27 Plaza and Megonko Road
The signalized intersection of Route 27 (North Main Street) at Megonko Road and the north driveway to
the 9/27 Plaza is also included within the study area. Route 27 southbound generally provides a single
lane of travel, but widens at the intersection to provide a left turn lane into the 9/27 Plaza, with a lead
phase for left turns. Route 27 northbound also widens from a single travel lane to provide a right turn lane
into the plaza. As previously discussed, traffic from both directions on Route 27 and from Route 9
eastbound must use this driveway to access the plaza. Only traffic from Route 9 westbound can access the
driveway at the off-ramp from Route 9 westbound to Route 27 northbound. Conversely, only traffic
exiting to Route 27 northbound can use the ramp driveway to exit; vehicles bound for Route 27
southbound, Route 9 and Lake Shore Road must turn left from the signalized driveway.
Route 27 northbound at 9/27 Plaza
The 9/27 Plaza driveway provides a wide entry lane and a two lane approach, separated by a raised
median. Approach lane markings are not provided, although the two lanes appear to operate as left and
right turn lanes. Megonko Road is a driveway under signal control serving several medical office
buildings.
Sidewalks are provided along both sides of Route 27 north of the intersection, and along the west side of
Route 27 south of the intersection. The sidewalk along the west side continues along the west side of the
ramp towards Route 9. A crosswalk is provided on the north leg of the intersection with pedestrian signals
and pushbuttons activating an exclusive pedestrian phase.
Crash Data
Crash data provided by the Natick Police Department and summarized by BETA Group show 395 crashes
from January 2010 to October 2013. Crash summaries and collision diagrams are included in the
Appendix, which summarize and categorize counts by intersection within the overall study area. Natick
Police noted that crashes in this area comprise 23% of all crashes town-wide.
Page 8
Road Safety Audit—Route 27 over Route 9 and Interchange—Natick, MA
Prepared by BETA Group, Inc.
One clear trend that occurs when reviewing the crash data is the number of rear-end crashes. 296 of the
395 crashes (75%) are rear-end crashes occurring at the end of a ramp. Rear-end crashes are common
with this type of ramp alignment where entering vehicles must judge available gaps, exacerbated by the
fact that the ramp alignment requires drivers to be looking over their shoulder rather than forward where a
vehicle may still be stopped unexpectedly. Traffic congestion may also contribute to driver frustration,
which can create a greater variance in levels of driver aggression.
Rear-end crashes are most common on the STOP-controlled ramps entering Route 9. The on-ramp from
Route 27 northbound to Route 9 westbound featured the highest number of crashes, with 84 during the
study period. The ramps from Route 27 southbound to Route 9 westbound and to Route 9 eastbound both
experienced 71 crashes. The ramp from Route 27 northbound to Route 9 eastbound experienced the
fewest crashes of the Route 9 on-ramps, with 30 during the study period. Rear-end crashes are also
common on the ramps exiting Route 9 onto Route 27; with 17 on the ramp from Route 9 eastbound to
Route 27 northbound, 14 on the ramp from Route 9 eastbound to Route 27 southbound, and seven on the
ramp from Route 9 westbound to Route 27 northbound. The one ramp which did not experience a
significant number of rear-end crashes is the ramp from Route 9 westbound to Route 27 southbound,
which is not unexpected because this ramp uses the two-way connector road between the ramp and Route
27, and enters Route 27 at a right angle under STOP control. Two rear-end crashes and one sideswipe
crash occurred departing this ramp.
A review of the remaining crash data indicates some clear trends. Angle crashes are common at both ends
of the two-way connector roadway connecting Route 27 with the ramp from Route 27 southbound to
Route 9 westbound. Three angle crashes occurred on the ramp side of the connector, where a wide
undefined roadway and lack of pavement markings may create confusion for drivers as to intended rightof-way and available lane width. Seven angle crashes occurred at the flasher intersection at Route 27,
which may indicate drivers taking chances on unacceptable gaps. Eight crashes occurred at the signalized
intersection of Route 27 and the 9/27 Plaza driveway, five of which were angle crashes that may indicate
clearance violations or drivers taking chances on unacceptable gaps. Rear-end crashes are typical along
Route 27 both at and outside of the intersections, which is likely a sign of congestion along the corridor.
Two bicycle crashes were identified within the study area, both of which involved a bicyclist traveling
against traffic. One involved a vehicle exiting a driveway onto Route 9 east that struck a bicyclist heading
west, while the other occurred departing the ramp from Route 9 eastbound to Route 27 northbound, in
which a vehicle struck a bicyclist traveling south on the northbound side of the road. No pedestrian
crashes were identified during the study period.

Audit Observations
Following a brief introduction to the RSA process and a summary of existing geometry and crash
information, the audit participants were asked to discuss safety issues along Route 27 and Route 9 in the
vicinity of the interchange. The review of existing intersection conditions included a review of aerial
photos and Google Street View images, during which time audit participants offered observations on
safety issues. A summary of those major safety considerations is as follows:

Lack of Acceleration/Deceleration Lanes – The existing ramp geometry provides limited room for
acceleration and deceleration. This is especially true between the loop ramps under the Route 27
overpass, which provide approximately 350 feet of shared acceleration/deceleration on the eastbound
side, and 200 feet on the westbound side. Deceleration lanes are provided in advance of the
interchange on Route 9 in both directions, but no acceleration lanes are provided entering Route 9
westbound from Route 27 southbound or entering Route 9 eastbound from Route 27 northbound. The
lack of adequate acceleration lanes is likely a significant contributor to the history of rear-end crashes
on ramps entering Route 9.

Ramp Stop Control – The unique geometry of the interchange creates sharp entry angles to Route 9
for all ramps, which are all under STOP control. Drivers expecting a more typical ramp alignment
may practice a rolling stop, introducing variance in expected driver behavior which can lead to rearend crashes on ramp merges.

Visibility - Issues related to visibility are also likely contributors in rear-end crashes exiting the
ramps. Restrictions to visibility create further variance in driver behaviors when judging acceptable
gaps.
o
Overgrown vegetation and the existing bridge carrying Route 27 over Route 9 block visibility of
approaching Route 9 traffic for vehicles entering from Route 27. This is especially true for the
ramp entering Route 9 westbound from Route 27 southbound and the ramp entering Route 9
eastbound from Route 27 northbound, which are the same two ramps previously noted to have no
acceleration lanes.
o
Signs and utility poles located in the exit gore further restrict visibility of Route 9 traffic for
drivers entering from Route 27.
Looking east entering Route 9 westbound


Advance Signage – Overhead signage is provided for Route 27 on Route 9 westbound, but only
smaller ground mounted signage is provided on Route 9 eastbound. It was noted that overhead
signage was not provided eastbound as part of the most recent Route 9 signage update because of the
lack of available right-of-way for sign support installation.

Cut-Through Traffic – A number of alternative routes from Route 27 to Route 9 westbound exist due
to the connection between Route 27 and Lake Shore Road, and between Lake Shore Road and Route
9. It was noted that more aggressive drivers pick the least congested path, which may involve using
Lake Shore Road to cut through to Route 9. This cut-through traffic creates additional turning
movements between Lake Shore Road and the ramp, where several angle crashes occurred.

Traffic Congestion – The study interchange between two busy roadways experiences congestion and
delay, especially during peak hours. Congestion can increase driver frustration, which creates greater
variances in driver aggression, which can lead to rear-end crashes when drivers incorrectly anticipate
the actions of other drivers. The lack of acceleration/deceleration lanes and the resultant weaving
areas on Route 9 are significant contributors to congestion at the interchange. Additional queuing
concerns include the following:
o
During peak periods, queues from the signalized intersection of Route 9 and Oak Street
approximately 1.5 miles east of Route 27 can extend to the Route 27 ramps. It is expected that
this congestion will improve once ongoing intersection improvements are complete at Oak
Street.
o
The signalized intersection of Route 27 and Bacon Street approximately 600 feet south of the
interchange ramps experiences backups due to the lack of left turn lanes. Left turning vehicles
block through vehicles while waiting for a gap in opposing traffic. This intersection is scheduled
to be reconstructed as part of a project to improve Route 27 both north and south of the
interchange. The project (MassDOT File No. 605034) is not currently funded.

Speed – Prevailing speed on Route 9, and the speed differential between entering vehicles and Route
9 through traffic, were identified as safety issues. Route 9 has a posted speed limit of 50 mph,
although it was suggested that driver speeds exceed 60 mph during uncongested periods. Vehicles
entering Route 9 from Route 27 are required to stop and have limited room for acceleration, which
creates a great variance in driver speeds and requires an entering driver to rapidly accelerate. These
issues may influence a driver’s gap acceptance, which may conflict with another driver’s expectation
of behavior and can contribute to rear-end crashes.

Two-Way Connector Operation – The two-way connector between Route 27 and Lake Shore Road
also serves as the ramp terminus to Route 27 southbound for vehicles exiting from Route 9
westbound. The connector intersects Route 27 under STOP control with an overhead flashing beacon.
Left turns are allowed on the approach to Route 27 to accommodate Lake Shore Road traffic heading
north on Route 27, but this also allows an alternate access to Route 27 north for traffic exiting Route
9 westbound. Five angle crashes at this location involved left turns to Route 27 north.
Page 11


Flashing Beacon – A flashing beacon supplements STOP control at the intersection between the twoway connector and Route 27. The yellow indication facing northbound traffic was out on the day of
the audit.

Sign Clutter – Sign clutter on Route 27 southbound at the
ramp entrance to Route 9 westbound, as shown at right,
may create confusion for southbound Route 27 traffic. A
construction sign at this location references construction at
Route 27 and Route 135, which was completed several
years ago.

Pedestrian Accommodations – Several issues related to
pedestrian accommodation were discussed by the audit team.
o
Continuous sidewalks are not provided along either side of Route 27 through the study area.
Sidewalk in the vicinity of the signalized intersection of Route 27 and the 9/27 Plaza driveway
follows the southbound ramp towards Lake Shore Drive, and sidewalk along the west side of
Route 27 in the vicinity of the bridge is narrow and in poor condition. A worn pedestrian path
along the east side of Route 27 indicates pedestrian travel demand.
o
Crosswalks and ramps are provided across the entry and exit ramps at Route 9, but pedestrian
crossings at these locations are unprotected. Previously identified concerns related to visibility
and speed can compromise pedestrian safety at these ramp crossings.
o
Although no crashes involved pedestrians, the lack of safe facilities as noted above may
encourage vehicle trips even amongst people who live close enough to walk. It was suggested that
the residential neighborhoods south of Route 9 generate pedestrian demand to the 9/27 Plaza.
o
Pedestrians have been observed crossing Route 9 by jumping over the guardrail that separates the
eastbound and westbound roadways.

Bus Stops – Stops are presently located on Route 9 in both directions in the vicinity of the
interchange. The stop on Route 9 eastbound is located adjacent to the acceleration/deceleration lane
between the two loop ramps, and is not used because its location requires buses to slow in the outside
travel lane on Route 9 before crossing vehicles departing and accelerating from the ramp from Route
27 southbound to Route 9 eastbound. The stop on Route 9 westbound is also not presently used; its
location required buses to cross accelerating vehicles departing the ramp from Route 27 southbound
and Lake Shore Road to Route 9 westbound. Safety concerns related to bus and vehicle conflicts as
well as pedestrian travel were expressed when discussing bus operations.

Bicycle Accommodation – Bicycle accommodations are not provided along Route 27. Shoulders of
an adequate width to accommodate bicycles are not consistently provided.

Drainage – It was noted that water ponds on Route 9 under Route 27 during heavy precipitation. This
can further exacerbate acceleration/deceleration and weaving concerns, and can create icing concerns
during the winter months.


Lighting – It was suggested that lighting is inadequate at the interchange, especially in areas where
crosswalks cross the ramps. It was also noted that the proximity of retail parking areas and car
dealerships produces brighter illumination outside the roadway, which reduces the effectiveness of
existing roadway lighting.

Guardrail Reflectors – Reflectors are missing or damaged along the guardrails separating the ramps in
the southwest and northeast quadrants of the interchange. One fixed object crash was reported along
the ramp in the southwest quadrant.

Potential Safety Enhancements
Following review of available materials and a discussion of existing safety issues, audit participants were
asked to consider improvements. Audit participants were encouraged to consider both short and long term
improvements for each issue. Each improvement considered has been categorized as short-term, midterm, or long-term based on the definitions shown in Table 2. Additionally, a cost category has been
assigned to each improvement based on the parameters set forth in Table 2.

Eliminate weaving areas and provide adequate length for acceleration and deceleration. The proposed
project was presented to the audit team, and it was noted that it eliminates weaving between the loop
ramps by eliminating the paired ramps in the northwest and southeast quadrants. An eastbound
deceleration lane precedes the off-ramp to Route 27 in the southwest quadrant, which allows left turns
to Route 27 northbound at a newly-created signalized intersection with Route 27. Right turns to Route
27 southbound will operate under yield control. Similar ramp geometry is proposed in the northeast
quadrant, where a westbound deceleration lane precedes the ramp. Acceleration lanes will extend
approximately 600 feet from the on-ramp gore in both directions on Route 9. This is a long-term, high
cost improvement incorporated into the project.
Eliminate STOP control of ramps on Route 9 as part of ramp reconstruction. The reconstruction
proposed in the project provides dedicated acceleration lanes, which do not require stop or yield
control at the end of the on-ramps. This will significantly reduce rear-end crashes which currently
occur at the ramp ends.
Eliminate visibility restrictions created by the existing bridge structure. The construction of the
proposed bridge and elimination of ramps in the northwest and southeast quadrants of the interchange
eliminates the need for drivers to look left past the bridge to judge acceptable gaps in oncoming
traffic. This will significantly reduce rear-end crashes at the ramp ends. It should be noted that drivers
will still need to look left to judge potential pedestrian conflicts.
Trim existing trees to reduce or eliminate visibility restrictions. It was noted that trimming regularly
takes place, which should be kept up as a short-term, low cost improvement in advance of the project.
It was also noted that the project is eliminating trees inside the ramps to provide stormwater
management basins.
Provide overhead signage on Route 9 eastbound for Route 27. The project should incorporate
overhead signage on Route 9 eastbound, and modify signage for Route 9 westbound based on the
proposed ramp reconfiguration. It was noted that the need for overhead signage is diminished with the
ramp reconfiguration, since drivers no longer need to differentiate between ramps for Route 27

northbound and southbound. This is a long-term, high cost improvement assumed to be incorporated
into the project. This improvement requires review of right-of-way.

Review sign and utility pole locations in conjunction with ramp reconstruction. Existing obstructions
created by signage and/or utility poles should be eliminated. This is a long-term improvement
assumed to be incorporated into the project. Poles to remain under the current design should be
reviewed to ensure that they do not create or exacerbate visibility restrictions.
Provide a traffic signal at the intersection of the Lake Shore Road connector and Route 27. The
existing two-way connector between Route 27 and Lake Shore Road is reconfigured under the
proposed design as a signalized approach opposing the ramp from Route 9 westbound. This
signalized leg provides access to Lake Shore Road and commercial driveways by essentially
reconfiguring the pavement from the current Route 27 southbound to Route 9 ramp, but does not
connect to Route 9. This is a long-term, high cost improvement.
Discourage cut-through traffic from Route 27 to Route 9 through Lake Shore Road. This is eliminated
as part of the project. The signalized approach described above provides access to Lake Shore Road
and commercial driveways including Valvoline, but does not connect to Route 9. The eastern
driveway of Sunnyside Plaza is also closed, which eliminates the direct connection from Lake Shore
Road to Route 9. This is a long-term, high cost improvement.
Include queue detectors on proposed off-ramps to avoid ramp traffic spilling back onto Route 9. It
was noted that the ramp reconfiguration, elimination of weaving areas, and provision of adequate
acceleration and deceleration lanes will reduce congestion that currently exists at the interchange.
Audit participants expressed concern that the traffic signals proposed at the end of the Route 27 offramps will create queues that can potentially back up onto Route 9. Queue detectors will add green
time for the ramps when queues exist. This is a long-term, medium cost improvement that can be
included in the proposed project.
Consider the effect of the existing Route 27/Bacon Street intersection on the proposed traffic signals.
It was suggested that current queuing concerns at the intersection of Route 27 and Bacon Street will
negatively impact operations along Route 27 over Route 9, and that proposed improvements at Bacon
Street should precede or accompany interchange improvements. This is a long-term, high cost
improvement that should be considered as part of the proposed project.
Continue speed enforcement in the area. This is a short-term and ongoing measure, the cost of which
is reduced enforcement elsewhere.
Relocate the STOP sign on the two-way connector approach to Route 27, and provide a STOP word
mark on the pavement behind the stop line. This is a short-term, low cost improvement that will
reinforce the need to stop and the location where vehicles must stop.
Replace the northbound-facing yellow indication in the existing flashing beacon. This is a short-term,
low cost improvement.

Review signs and sign locations facing southbound Route 27 traffic at the on-ramp to Route 9
westbound. The number and location of existing signs may not clearly indicate that Route 27 traffic
must stay left at this ramp location. This is a short-term, low cost improvement.
Remove the construction sign referencing construction of Route 27 at Route 135. This sign is
outdated and can be removed. This is a short-term, low cost improvement.
Provide sidewalks along both sides of Route 27 throughout the project. Sidewalks are proposed as
part of the project and will connect to existing sidewalks at the project limits. This is a long-term,
high cost improvement. Crosswalks with pedestrian signals and pushbuttons will be provided at the
newly-created signalized ramp intersections.
Review locations of crosswalks and wheelchair ramps crossing the existing ramps connecting Route 9
westbound and Route 27 northbound. Crosswalks should be placed to optimize visibility of
pedestrians for approaching drivers. Crosswalk signage should be upgraded and/or relocated as
necessary. This is a short-term, potentially medium cost improvement if crosswalks and wheelchair
ramps need to be relocated. The project design should also be reviewed to determine the optimal
location for pedestrian crossings.
Provide a more significant barrier in the center of Route 9 to discourage pedestrian crossings. It was
noted that the project will replace the existing guardrail with a high concrete barrier. This long-term,
high cost improvement incorporated in the project will create greater impedance for pedestrians and
encourage them to use the sidewalks proposed over the reconstructed Route 27 overpass.
Review bus stop locations on Route 9, and consider stops on Route 27. Bus stops are relocated as part
of proposed improvements to be adjacent to proposed acceleration lanes in both directions on Route
9. This will require buses to cross accelerating vehicles to reach the stop location. This does allow
departing buses the benefit of the ramp acceleration lane, whereas locating the bus stop adjacent to
the deceleration lane would create a conflict between accelerating buses leaving the stop and
decelerating vehicles using the ramp. It was also suggested that stops should be provided on Route
27, and that shelters could be provided adjacent to the proposed stops on Route 9. This is a long-term,
high cost improvement that should be considered along with project improvements and requires
coordination with MWRTA.
Provide warning signage in conjunction with proposed bus stop locations. Signs could be located on
the Route 27 to Route 9 on-ramp in both directions to warn drivers of potential conflicts with slowing
and stopped buses. This is a long-term, low cost improvement that should be considered along with
project improvements.
Widen shoulders along Route 27 to provide bicycle accommodation. Minimum 5-foot wide shoulders
are required to meet MassDOT’s current standard for bicycle accommodation. This long-term, high
cost improvement is included in the project.
Upgrade drainage to eliminate ponding at the low point on Route 9 under Route 27. It was noted that
the planned improvements replace existing drain pipes with larger pipes, and the inclusion of
Page 16

Prepared by BETA Group, Inc.
stormwater management basins inside the proposed ramps will facilitate drainage. This is a long-term,
high cost improvement included in the project.



Review vegetation proposed for stormwater basins to ensure that it will not impede visibility. Low
growth vegetation should be specified as part of the proposed basins, which are a long-term, high cost
improvement included in the project.
Consider upgrading street lighting in the area, where feasible. Existing street lighting is inconsistent
and does not provide adequate lighting for pedestrians. This is a long-term, high cost improvement
that should be considered as part of proposed improvements.
Replace guardrail reflectors. Damaged and missing reflectors should be replaced as a short-term, low
cost improvement.
Summary of Road Safety Audit
Table 3 summarizes potential recommendations discussed by the audit team. The recommendations are
categorized based on the potential safety payoff, as well as by time frame and cost. The safety payoff is a
qualitative judgment of the effectiveness of the potential safety improvements. Each recommendation has
a responsibility assigned to it stating whether MassDOT or the Town of Natick would be responsible for
implementing the recommended improvement. “Project” refers to improvements that are assumed to be
included or could reasonably be accommodated as part of planned improvements at the intersection. Costs
for “Project” improvements, where provided, are an order of magnitude estimate which estimates the cost
of the improvement if completed independent of the project.
