Background
The Massachusetts Department of Transportation (MassDOT) has developed a Strategic
Highway Safety Plan to maximize safety for users of the roadway system and one of the many
strategies of this plan is to conduct a Road Safety Audit (RSA) at high-crash locations. A RSA is
defined by the Federal Highway Administration (FHWA) as a formal safety examination of an
existing or future road or intersection by an independent, multidisciplinary audit team. The safety
improvements recommended through a RSA typically vary from low cost measures which may
be completed as short-term measures to more significant improvements that are more costly,
long term measures.
The Washington Street (Route 1) at Como Drive intersection is a “T” type intersection under
STOP sign control. The intersection has been determined by MassDOT to be among the State’s
high crash list for the Southeastern Regional Planning and Economic Development District
(SRPEDD), making a RSA a requirement prior to any new design and development in the area.
Como Drive intersects Washington Street from the west at a right angle to form a “T” type
intersection. The intersection is approximately 550 feet north of the Washington Street and May
Street intersection, which is under traffic signal control.
In response to the high incidences of crashes at this intersection, MassDOT requires that this
RSA be prepared to identify safety issues and potential enhancements that may be implemented
in conjunction with future public or private development projects.
Project Data
The RSA meeting took place on Monday March 7, 2016 at 10:00 AM at the South Fire Station,
1476 West Street in Attleboro. The audit team Members and their affiliations participating in the
RSA meeting are listed in Table 1.
The initial step in completing the RSA process is to prepare background material for the audit
site. The background material for this RSA included crash data from January 2010 to December
2013, summarized as collision diagrams and in graph format. This information was provided to
the audit team as part of the meeting agenda. The audit team was encouraged to review the data
and conduct their own site visit of the intersection to become familiar with the safety issues to be
discussed.
The audit team assembled as scheduled at the South Fire Station conference room and the
background information was briefly reviewed. A discussion of some of the intersection concerns
was also initiated followed by the audit team visiting the intersection.

At completion of the of the site visit, the audit team returned to the South Fire Station to continue
discussion of the intersection safety concerns as well as possible enhancements. The audit
meeting was adjourned with a brief explanation of the remainder of the process and approximate
time schedule to complete the audit report.

Project Location and Description
The Washington Street (Route 1) at Como Drive intersection is located approximately 1.7 miles
south of the Route I-295 and Washington Street (Route 1) interchange in Attleboro; refer to
Figure 1 for the Locus Map. Washington Street within this area is abutted mostly by commercial
and retail land uses with many driveways and curb cuts providing access onto Washington
Street.
Washington Street is a north to south roadway connecting Interstate Route 295 (I-295) to the
north and Interstate Route 95 (I-95) to the south, and has a Federal Functional Classification of
Minor Arterial. It is under the jurisdiction of the Massachusetts Department of Transportation
(MassDOT). It is essentially a four-lane roadway with designated turn lanes interspersed at
major traffic signalized intersections as well as other significant turn locations. In the vicinity of
the Como Drive intersection, Washington Street is undivided and posted for 40 MPH in both
directions. The four-lane cross-section has no shoulders or bicycle lanes. There are no sidewalks
on either side of Washington Street. The Washington Street horizontal alignment is straight north
of Como Drive but has a slight curve south of the intersection. Washington Street is intersected
by May Street approximately 550 feet south of Como Drive. The Washington Street and May
Street intersection is under traffic signal control. A narrow median separates directional traffic on
Washington Street beginning approximately 160 feet south of Como Drive and extends to the
May Street intersection. The Washington Street vertical profile slopes up to a crest vertical curve
north of Como Drive. To the south, the Washington Street vertical profile is relatively flat.

A full-access driveway, approximately 30 feet wide, exists on Washington Street immediately
north of the Como Drive intersection (approximately 90 feet, centerline to centerline). This
driveway services several businesses located in a strip mall at this neighboring parcel of land.
Como Drive is an east to west local roadway providing residential access to Washington Street.
The “T” type intersection is under STOP sign control at Washington Street. Como Drive is a two
way, approximately 30 foot wide roadway, which has no pavement markings to divide
directional traffic or at the STOP sign approach to Washington Street. An aerial view of the
Washington Street at Como Drive intersection is provided as Figure 2.

Audit Observations and Potential Safety
Enhancements
After the audit team participated in the RSA site visit on March 7, 2016, the audit team members
returned to the conference room at the South Fire Station and the group discussion continued in
more detail on the various safety issues that were observed to have an impact on the intersection
safety. Additionally, potential enhancements to mitigate the safety issues were discussed.
The safety issues that were observed and discussed include:
1. The crest vertical curve along Washington Street restricts visibility of on-coming vehicles for
those exiting Como Drive.
2. The ground signs and vegetation along the west side of Washington Street restricts visibility
of vehicles exiting Como Drive.
3. No deceleration lane on Washington Street southbound approaching Como Drive.
4. Poor location of posted speed limit sign along Washington Street southbound approaching
Como Drive.
5. The full-access driveway in close proximity to the Como Drive intersection causes confusion
and creates increased conflicts.
6. The Como Drive intersection is somewhat camouflaged and not readily visible to southbound
vehicles on Washington Street.
7. Vehicles queue from the May Street intersection up to and at times past the Como Drive
intersection.
8. Vehicles travelling northbound on Washington Street approaching Como Drive from the
south experience restricted visibility.
9. Lack of proper pedestrian accommodations on Washington Street.
10. No shoulders and no bicycle accommodations on Washington Street.
11. Poor visibility of the STOP sign at the Como Drive approach to Washington Street.
12. Lack of pavement markings on Como Drive approaching Washington Street.
Each of the safety issues listed above is described in more detail in the following paragraphs
along with the potential enhancements discussed
during the RSA meeting.
Observed Safety Issue #1 - The crest
vertical curve along Washington Street
restricts visibility of on-coming vehicles
for those exiting Como Drive.
Washington Street in the vicinity of Como Drive
has a straight horizontal alignment. However, the
Washington Street vertical profile from Como
Drive to the north is on an upslope with a crest
curve approximately 400 feet north of Como Drive. Exiting Como Drive looking north along
Washington Street is the crest curve.
Page 6
Road Safety Audit—Washington St. at Como Dr., Attleboro
Bayside Engineering, Inc.
This appears to create a visibility restriction for exiting vehicles, especially for those wanting to
turn left onto Washington Street northbound. The high percentage of rear-end crashes on
Washington Street may be the result of southbound vehicles stopping short due to avoid a
collision with vehicles from Como Drive entering the traffic stream but are unable to see on­
coming vehicles from a safe distance.
Potential Safety Enhancements:
1. Perform Stopping Sight Distance (SSD) and Intersection Sight Distance (ISD) studies to
determine if sufficient distance exists based on the actual 85th percentile travel speeds for
vehicles to exit left and right from Como Dive.
2. If the sight distance for left turning vehicles onto Washington Street northbound is found
deficient, it was suggested Como Drive traffic be restricted to right in and right out only.
Vehicles wanting to go northbound on Washington Street would be directed to exit Como
Drive in the other direction to Heather Street to May Street and turn left at the Washington
Street traffic signal.
3. Investigate the possibility of physically preventing left turns onto Washington Street
northbound by extending the median that currently ends south of Como Drive to some point
north of Como Drive. This will require Washington Street to be widened.
4. Reconstruct the Washington Street profile to provide a crest curve that provides sufficient
sight distances based on the actual 85th percentile travel speeds.
Observed Safety Issue #2: The ground signs and vegetation along the west side of
Washington Street restricts visibility of vehicles exiting Como Drive.
Several large, private signs have been placed along the west side of Washington Street fairly
close to the edge of road. These private advertising signs appear to be well within the existing
right of way. The signs obstruct the view of drivers exiting Como Drive and looking north for
on-coming vehicles. Additionally, the vegetation and trees along this sight line add to this issue.
Although not as severe, vegetation and trees along the southwest corner also restrict the sight line
looking south. This condition will worsen as the vegetation blooms during the growing season.
Signs and vegetation at west edge of Washington Street - looking north (L) and south (R)
Page 7
Road Safety Audit—Washington St. at Como Dr., Attleboro
Bayside Engineering, Inc.
Potential Safety Enhancements:
1. The private advertising sign should be relocated outside the state layout and onto private
property.
2. The vegetation and trees should be examined once it has bloomed and cut back or pruned if it
is found to be obstructing the visibility of vehicles exiting Como Drive.
Observed Safety Issue #3: No deceleration lane on Washington Street southbound
approaching Como Drive.
The posted speed limit on Washington Street is 40
MPH. Vehicles traveling at this speed or higher in
some cases must slow down significantly in order to
make a right turn into Como Drive (or the adjacent
driveway). Without a deceleration lane vehicles must
slowdown in the travel lane. This is a safety issue as
evidenced by the high number of rear end type
crashes. The crashes occur as a result of vehicles
following too close or the vehicle slowing down is an
unexpected maneuver.
Potential Safety Enhancements:
Washington Street southbound approaching
Como Drive lacks a deceleration lane.
1. Construct a deceleration lane for southbound
vehicles approaching and wanting to turn right into Como Drive or the adjacent driveway.
Observed Safety Issue #4: Poor location of posted speed limit sign along
Washington Street southbound approaching Como Drive.
It was suggested that the speed limit sign located at the
top of the crest curve on Washington Street facing the
southbound direction is a poor location as it appears to
emphasize the 40 MPH speed limit instead of
encouraging and warning vehicles to slow down.
Potential Safety Enhancement:
1. Conduct a review of the speed limit zones to
determine if the speed limit sign can be relocated
to a more appropriate location.
2. Investigate the possibility of installing a warning Speed limit sign at top of crest curve
sign such as an advance intersection sign or an approaching Como Drive.
advance traffic signal ahead sign in its place. It was suggested such signage may have the
more appropriate effect of causing vehicles to slow down as they approach Como Drive.
Page 8
Road Safety Audit—Washington St. at Como Dr., Attleboro
Bayside Engineering, Inc.
Observed Safety Issue #5: The full-access driveway in close proximity to the
Como Drive intersection causes confusion and creates increased conflicts.
A full-access driveway, approximately 30 feet wide,
exists on Washington Street to the north of the Como
Drive intersection. This driveway services the strip
mall adjacent to Como Drive. Vehicles traveling
southbound on Washington Street make the same
maneuver to turn right into the driveway or into
Como Drive. This confuses vehicles following the
turning vehicle, especially if it is following too close
behind as it slows down. Additionally, exiting
vehicles are an issue, especially if there are exiting
vehicle both at the driveway and at Como Drive.
Potential Safety Enhancements:
Como Drive and the adjacent driveway.
1. Investigate the possibility of relocating the strip
mall driveway to create more separation from Como Drive and create a safer condition.
2. Redesign the mall driveway as a right turns in and a right turns out only driveway, thus
eliminating this as a point of conflict. Vehicles wanting to go Washington Street northbound
can access Como Drive and make a left turn for Washington Street northbound.
3. Evaluate the possibility of closing the driveway on Washington Street and redesign a full
access driveway onto Como Drive. This will force all turns be made at the Washington Street
at Como Drive intersection.
Observed Safety Issue #6: The Como Drive intersection is somewhat camouflaged
and not readily visible to southbound
vehicles on Washington Street.
Approaching Como Drive from Washington Street in
the southbound direction, the intersection is not
readily visible which may result in drivers not being
prepared for conflicting movements to occur. One
reason for this has already been discussed; the
intersection does not come into view until after
reaching the top of the crest vertical curve. Another
reason also discussed is the large ground signs
placed so close to the edge of road. The intersection
blends in and is camouflaged by the surrounding Como Drive intersection is not readily
vegetation and also somewhat obstructed from view visible from Washington Street southbound.
by the large sign for the strip mall located between
the driveway and Como Drive.
Page 9
Road Safety Audit—Washington St. at Como Dr., Attleboro
Bayside Engineering, Inc.
Potential Safety Enhancements:
1. Install a warning sign at the top of the crest curve indicating the intersection ahead. The sign
will be visible prior to reaching the crest curve and drivers will be aware to look for the
intersection beyond the crest curve.
Observed Safety Issue #7: Vehicles queue from the May Street intersection up to
and at times past the Como Drive intersection.
Washington Street is intersected by May Street
approximately 550 feet south of Como Drive.
The Washington Street and May Street
intersection is under traffic signal control. A
narrow median separates directional traffic on
Washington Street beginning approximately 160
feet south of Como Drive and extends to the May
Street intersection. The Washington Street
southbound approach to May Street consists of
two through lanes and a designated left turn lane
which is approximately 125 feet long (storage
capacity for approximately five vehicles). It was
reported that the left turn lane capacity during the Vehicles queue from May Street traffic
rush hours is often exceeded causing left turn signal up to Como Drive.
vehicles to queue and block the inner through lane.
Local drivers are aware of this and often try to switch from the inner to the outer through lane to
avoid getting blocked. The switching of lanes may be the cause of the side swipe type crashes.
Potential Safety Enhancements:
1. Collect traffic volume data and analyze traffic signal operations to determine signal phasing
is at optimum, especially for the left turn phase.
2. Determine the 95th percentile queue length from the analysis and determine if the existing left
turn lane length can be increased to meet the demand.
Observed Safety Issue #8: Vehicles travelling northbound on Washington Street
approaching Como Drive from the south experience restricted visibility.
An audit team member stated that vehicles travelling northbound toward Como Drive do not
have sufficient sight distance to see vehicles stopped on Washington Street to allow southbound
vehicles who want to turn left into the driveways north of Como Drive. The issues causing the
restricted visibility include a crest vertical curve in the Washington Street profile and a curve in
the horizontal alignment. Additionally, the east side of Washington Street from May Street past
Como Drive includes: large signs placed close to the edge of the road, vegetation growing close
Page 10
Road Safety Audit—Washington St. at Como Dr., Attleboro

to the edge of the road and a large rock outcrop just
north of May Street that is also somewhat close to the
edge of road.
Potential Safety Enhancements:
1. Conduct a SSD study for both the horizontal and
vertical alignment based on the actual 85th
percentile travel speeds.
2. Based on the study results, address the issues and
provide sight distances that meet design
guidelines.
Washington Street looking north from
May Street Intersection.
3. Perform clearing and pruning of any vegetation to eliminate visibilities issues.
4. Relocate any roadway mounted private signs to outside the state layout line so they do not
hinder visibility.
Observed Safety Issue #9: Lack of proper pedestrian accommodations on
Washington Street.
There are no pedestrian accommodations on either Como Drive or Washington Street.
Washington Street has no sidewalk on either side nor are there any cross walk pavement
markings or wheel chair ramps to cross Washington Street or Como Drive. The nearest
pedestrian accommodations are at the May Street intersection approximately 550 feet to the
south or at the Cumberland Avenue
intersection approximately 1900 feet
to the north. It was noted that this is a
high priority location for pedestrian
accommodation as there is a
connectivity issue between the May
Street
intersection
and
the
Cumberland Avenue intersection.
Both of these signalized intersections
have pedestrian signal housings with
push buttons, cross walks and wheel
chair
ramps to cross Washington The intersection lacks pedestrian accommodations.
Street.

Road Safety Audit—Washington St. at Como Dr., Attleboro
Bayside Engineering, Inc.
Potential Safety Enhancements:
1. As part of any future development and proposed work, the intersection should be evaluated
and made to comply with Engineering Directive E-14-001 dated 02/04/14, Design Criteria
for MassDOT Highway Division Project for compliance with design criteria relative to
pedestrian accommodations. This directive supports the MassDOT Healthy Transportation
Policy Directive P-13-0001 dated 09/09/13.
Observed Safety Issue #10: No shoulders and no bicycle accommodations on
Washington Street.
Washington Street has no shoulders and no bicycle accommodations. The roadway cross section
in the vicinity of the intersection consists of two lanes in each direction separated by a double
yellow centerline, and a white edge of road line offset approximately one foot from edge of road.
Potential Safety Enhancements:
1. As part of any future development and proposed work, the intersection should be evaluated
and made to comply with Engineering Directive E-14-001 dated 02/04/14, Design Criteria

Policy Directive P-13-0001 dated 09/09/13.
Observed Safety Issue #11: Poor visibility of the STOP sign at the Como Drive
approach to Washington Street.
The Como Drive approach at its intersection with
Washington Street is under STOP sign control.
The STOP sign is located off the edge of
pavement, behind the guard rail and slight around
the curved corner. Como Drive has no sidewalk
and the roadway is abutted with overgrown
vegetation. Audit team member noted that once
the vegetation blooms the sign may have limited
visibility to approaching vehicles.
Potential Safety Enhancements:
1. Review sign location and relocate to improve
visibility for approaching vehicles.
Como Drive approach to Washington Street.
2. Install a stop ahead warning sign (W3-1) in advance of the intersection.
Page 12
Road Safety Audit—Washington St. at Como Dr., Attleboro
Bayside Engineering, Inc.
Observed Safety Issue #12: Lack of pavement markings on Como Drive
approaching Washington Street.
Como Drive is two way, approximately 30 feet wide, but has no pavement markings to divide
directional traffic or edge lines to delineate edge of road. Additionally, there is no stop line at the
STOP sign approach to Washington Street.
Potential Safety Enhancements:
1. Install pavement markings on Como Drive approaching Washington Street.
Summary of Road Safety Audit
The RSA team identified a number of safety issues and potential safety enhancements for the
intersections of Washington Street at Route I-95 Como Drive based on their on-site field
observations, the meeting discussion and a review of the available data. The safety
improvements, as is typical, vary from low cost quick fixes to significant improvements with
higher costs and a long range time frame to implement. A breakdown of the time frame and costs
categories is presented in Table 2.
