Background
The intersection of Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road is within the Top
5% of High Crash Locations on Cape Cod. The intersection is currently at the 25% Design stage, funded
by the Town of Barnstable, and is eligible to receive Highway Safety Improvement Program (HSIP)
funding for construction if a Road Safety Audit (RSA) is conducted and the proposed design incorporates
the safety improvements identified in the RSA.
The 25% Design effort included improvements to Meetinghouse Way at the intersections with Route 6
EB/Service Road (southern intersection) and the WB ramps (northern intersection), but following review
of background materials it is apparent that the safety concerns are predominantly at the southern
intersection. As such the focus of the RSA was on the southern intersection; however, some
recommendations were also made at the northern intersection.
Project Data
The audit team conducted an RSA for the intersection of Meetinghouse Way (Route 149)/Route 6 EB
Ramps/Service Road in Barnstable, Massachusetts, on Thursday, January 7, 2010. The RSA agenda
appears in Appendix A. Table 1 lists the audit team members and their affiliations. Appendix B
provides contact information for all team members.

Project Location Description
The intersection of Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road is located in the
Town of Barnstable, as shown in the aerial image in Figure 1. The West Barnstable Conservation Area is
located to the southwest of the intersection. The area is a popular one for mountain bikers. The Claire
Saltonstall Bikeway (Bike Route 1) is located along the south side of the Service Road east of
Meetinghouse Way.
Prior to the RSA, in order to begin assessing possible safety issues, the team reviewed collision diagrams
and a crash detail summary based on crash records supplied by the Barnstable Police Department. Of
31 crashes related to the intersection from March 1, 2006, through November 30, 2008, 26 (nearly 84%)
were angle crashes. Crashes typically occurred on dry pavement (27, or 87%) and during daylight hours
(30, or 97%). Crashes most commonly occurred when vehicles exited either the Route 6 EB Ramp eastbound or the Service Road westbound approach, either onto or crossing Meetinghouse Way. Several
other crashes were associated with Service Road eastbound, which is located approximately 120 feet
south of the Route 6 EB Ramp approach. Appendix C provides the detailed intersection crash data from
2006 through 2008. Other intersection data such as traffic volumes are presented in Appendix D.
The intersection is the junction of the following roadways, which are categorized according to
Massachusetts Department of Transportation (MassDOT) Office of Transportation Planning functional
classifications:
Meetinghouse Way (Route 149) is an urban minor arterial roadway owned by MassDOT from Church
Street to Service Road eastbound. Meetinghouse Way (Route 149) runs north–south and connects West
Barnstable and Marstons Mills, both villages of the Town of Barnstable. Meetinghouse Way provides
one travel lane in each direction. Per the speed regulations, the speed limit on Meetinghouse Way at the
intersection with the Route 6 EB Ramps/Service Road is 35 miles per hour (mph) in both directions.
Speed limit signs are posted in the vicinity of the intersection.
Route 6 On- and Off-ramps are urban minor arterials owned by MassDOT. Each of the ramps provides
one travel lane for vehicles entering or exiting Route 6. The Route 6 eastbound off-ramp is STOPcontrolled for left-turning and through vehicles and yield-controlled for right-turning vehicles at the
junction of Route 149.
Service Road is an urban collector owned by the Town. Service Road consists of one lane in each
direction. The posted speed limit is 35 mph. The Service Road eastbound approach is located
approximately 120 feet south of the Route 6 EB ramps and is STOP-controlled at the intersection with
Meetinghouse Way. The Service Road westbound approach aligns opposite the Route 6 EB Ramps
approach and is also STOP-controlled. The Claire Saltonstall Bikeway is located on the south side of the
Service Road

Road Safety Audit Observations
Safety issues and possible enhancements were determined based on RSA team discussions and field
observations on Thursday, January 7, 2010. It should be noted that although the weather was clear and
cold, there was snow on the ground at the time of the audit. An RSA team member noted that there are
not typically any drainage problems at this location. The safety issues identified include:








Intersection control;
Complexity of the intersection geometry;
Limited sight distance on several approaches;
Faded pavement markings;
Unclear and insufficient wayfinding signage;
Limited pedestrian accommodations;
Limited bicycle accommodations; and
Vehicle speeds.
Several of these issues require further study and engineering judgment to determine the feasibility
of implementing enhancements to address them.
The following sections describe in more detail the safety issues and enhancements determined during
the RSA.
Page 5
Road Safety Audit—Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road, Barnstable
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #1. Intersection Control
Observation:
At this intersection, nearly
84% of the crashes from
2006 through 2008 were
angle crashes. Field
observations indicated that
drivers on the Route 6 EB
Ramp eastbound and
Service Road westbound
approaches may misjudge
the speed of approaching
vehicles on Meetinghouse
Way. Review of the crash
reports also indicates
several instances of a driver
failing to yield the right-ofway. In addition, a motorist
may choose to pass a leftView approaching the STOP sign on the Service Road westbound
turning vehicle on the right,
approach.
due to the width of Meetinghouse Way near the intersection. Several crashes involved a stopped motorist failing to see
the second vehicle passing on the right.
Enhancements:
1. Change the control of the intersection, utilizing either a traffic signal or a roundabout, to
reduce angle crashes and clarify control.
2. Include emergency pre-emption if a traffic signal is installed.

Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #2. Intersection Geometry
Observation:
The offset Service Road
eastbound approach,
located approximately 120
feet south of the Route 6
EB Ramp eastbound
approach, contributes to the
safety issues. A motorist
turning right from the
Route 6 EB ramp is
required to yield to
oncoming traffic; s/he is
looking to his/her left for
on-coming vehicles (the
expected area of conflict)
and not to the right toward
the Service Road eastbound
approach. An RSA team
View to the south (right) from the Route 6 EB Ramp eastbound
member noted that, in
right-turn lane. The Service Road eastbound approach is located
just beyond the YIELD sign.
general, there are too many
places for a motorist to look
for oncoming vehicles when entering and/or navigating through the intersection.
Enhancements:
1. Consider incorporating the Service Road EB approach into the intersection control (see
Safety Issues #1) or modify the geometry of the eastbound ramp to increase conspicuity
of vehicles entering the intersection from the Service Road EB approach. Consideration
should be given to redesigning the Route 6 EB right-turn ramp to force vehicles to make
a 90º turn and to increase the separation between the Route 6 EB and Service Road EB
approaches. The intersection could also be redesigned as a 5-leg roundabout,
incorporating both Service Road approaches. A change in traffic control will also reduce
the number of conflicts a motorist must look for; a signal or a roundabout could
accomplish this.
2. Any redesign should provide adequate turning radii to accommodate emergency vehicle
and truck access through the intersection. The West Barnstable Fire Department’s water
trucks are of particular concern for the Town, since firefighters must use water tankers to
fight fires because there is no water source north of Route 6 in West Barnstable. Include
apron for emergency and truck access if a roundabout is installed.

Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #3. Sight Distance
Observation:
Sight distance from the
Route 6 EB ramp eastbound,
Service Road eastbound, and
Service Road westbound
approaches is constrained by
the presence of trees and
shrubs near the edges of the
roadways.
Sight distance from the Service Road eastbound approach to the
left (north) is restricted by trees and shrubs.
The team also noted that sight
distance from the Route 6 EB Ramp
eastbound approach is further
constricted by the alignment of the
roadway. Both the horizontal and the
vertical curvature prevent a motorist
on that approach from easily seeing
an approaching vehicle.
Similarly, the bridge wall restricts
visibility of vehicles at the Route 6
EB ramps for motorists driving
southbound on Meetinghouse Way.
Sight distance from the Route 6 EB Ramp eastbound left-turn and
through lane to the left (north) is restricted by signs, trees, shrubs,
and the alignment of the roadway.
Page 8
Road Safety Audit—Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road, Barnstable
Prepared by Howard/Stein-Hudson Associates, Inc.
Enhancements:
1. Trim trees and shrubs adjacent to the roadways to provide adequate sight distance.
2. Change the control of the intersection by installing either a traffic signal or a roundabout
to lessen the effects of the horizontal and vertical alignment on sight distance. Install
appropriate advance signage to warn motorists of the change in control at the intersection.

Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #4. Pavement Markings
Observation:
The RSA team noted that pavement markings at the intersection are worn or missing—adding
to the confusion of motorists accessing Meetinghouse Way from the Route 6 EB ramps or
Service Road.
An RSA team member also noted that Meetinghouse Way northbound right-turn onto Route 6
WB is not clearly delineated making it difficult for motorists to determine when it is safe to exit
the WB ramp onto Meetinghouse Way.
Enhancements:
1. Re-stripe and maintain durable pavement markings at the intersection.
2. Delineate the Meetinghouse Way northbound through and right-turn lane at the
intersection with the Route 6 WB ramps.
Page 10
Road Safety Audit—Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road, Barnstable
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #5. Signage
Observation:
The RSA team noted that
wayfinding messages and
signage are generally
inconsistent at the
intersection. The signs on
Route 6 give direction to
specific villages of
Barnstable such as West
Barnstable and Marstons
Mills, but there are no
additional signs at the ramp
termini indicating which
direction to proceed after
exiting. In addition, a
number of local
organizations’ signs
opposite the Route 6 EB
ramps eastbound approach
contribute to sign clutter at
the intersection.
Signs clustered opposite the Route 6 EB Off-ramp eastbound
approach.
The RSA team noted that guide
signs to Route 6 on the Meetinghouse Way northbound approach
are blocked by a utility pole.
An RSA team member also noted
that visibility of Route 6 EB and
WB signage on Route 149 is also
constrained by overgrown trees.
Guide signs on Meetinghouse Way northbound are blocked by
a utility pole.
Page 11
Road Safety Audit—Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road, Barnstable
Prepared by Howard/Stein-Hudson Associates, Inc.
Enhancements:
1. Provide guide signs with messages consistent with those on the Route 6 mainline at the
ramp termini.
2. Remove or relocate local organizations’ signs to improve sign clutter.
3. Relocate Route 6 guide signs on the Meetinghouse Way northbound approach in advance
of the utility pole.
4. Ensure that all Route 6 guide signs are visible; trim trees and/or relocate signage as
appropriate.

Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #6. Pedestrian Accommodations
Observation:
The RSA team members noted that currently no paved sidewalks or crosswalks are provided.
However, in the non-winter months, it is evident that an informal path has been created along the
south side of Service Road and used by both pedestrians and bicyclists.
Enhancements:
1. With intersection improvement to a roundabout or traffic signal, include appropriate
pedestrian accommodations. If the intersection remains unsignalized, consider installing
crosswalks at the intersection with appropriate advance warning signage.
Page 13
Road Safety Audit—Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road, Barnstable
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #7. Bicycle Accommodations
Observation:
The Saltonstall Bikeway is located on the south side of Service Road. The RSA team members
also noted that several organized rides such as the Pan-Mass Challenge pass through the intersection at various times in the spring and summer months. In addition, a significant number of
cyclists use the intersection.
Enhancements:
1. Redesign of the intersection should incorporate bicycle accommodations such as a 4-foot
paved shoulder, bike route signing, and bicycle detection if a signal is installed.
Page 14
Road Safety Audit—Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road, Barnstable
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #8. Speed
Observation:
Per the speed regulations, the speed limit on Meetinghouse Way in the vicinity of the intersection
is 35 miles per hour (mph) in both directions. RSA team members noted that vehicles frequently
appear to be traveling faster than 35 mph. Speed may contribute to crashes at the intersection.
Enhancements:
1. Conduct a speed study to determine the prevailing speeds and adjust speed regulation as
necessary based on findings.
2. Increase enforcement in the vicinity of the intersection through the use of either speed
trailers or uniformed officers.
3. Reconfiguration of the intersection into a 5-leg roundabout will reduce speeds through
the intersection area.

Recommendations
Based on its observations and discussions, the RSA team identified the issues and possible enhancements
that could improve the safety at the intersection of Meetinghouse Way (Route 149)/Route 6 EB Ramps/
Service Road in Barnstable, Massachusetts.
Short-term recommendations include:

Re-striping and maintaining pavement markings.

Trimming trees along the edge of Meetinghouse Way (may not be necessary with roundabout
alternative).

Performing a speed study on Meetinghouse Way to determine prevailing speeds.

Enforcing speed limits on Meetinghouse Way.
To enhance the safety of the intersection of Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service
Road, the long-term recommendation is to improve the intersection geometry and install either a traffic
signal or a roundabout. Further study and design work need to be conducted to determine the feasibility
of making such improvements to the intersection.
Table 2 summarizes these safety issues, possible enhancements, estimated safety payoff, time frame, cost,
and responsibility. Safety payoff estimates are based on the approximate percent of crashes reduced by
enhancement and are categorized as low (<30%), medium (30% to 70%), and high (>70%). The time
frame is categorized as short-term (<1 year), mid-term (1 to 3 years), or long-term (typically >3 years).
Long-term improvements are typically considered to be substantial improvements with an expected
timeframe for implementation greater than 3 years; however, it is expected that improvements to the
intersection of Meetinghouse Way (Route 149)/Route 6 EB Ramps/Service Road would be advertised for
construction in FFY2010. The costs are categorized as low (<$10,000), medium ($10,001 to $50,000), or
high (>$50,000).
It is the responsibility of MassDOT to ensure that the designer incorporates the relevant safety
enhancements identified as part of this RSA.
