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 6 (Scenic Highway) between Route 25

and Route 3 because the corridor has experienced a significant number of crashes. A project is under

development to add shoulders and a center median to the segment of Route 6 between Nightingale Pond

Road and Edge Hill Road (MassDOT File No. 606082). The RSA is intended to identify potential short

and long term safety improvements that can be made along the corridor, 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.

Project Description

Route 6 (Scenic Highway) serves a significant role as a regional connector to and from Cape Cod. The

segment of Route 6 between Route 25 and Route 3 runs parallel to the mainland side of the Cape Cod

Canal. Route 25 provides freeway access from the ends of both I-195 and I-495 to the Bourne Bridge,

while Route 3 provides freeway access from the South Shore and metro Boston to the Sagamore Bridge.

Route 3 has an interchange before the Sagamore Bridge with Route 6, which continues across the bridge

and along Cape Cod as a freeway known as the Mid-Cape Highway.

The study segment of Route 6, shown in Figure 1, is functionally classified as a Principal Arterial and is

under MassDOT jurisdiction. Route 6 is signed as an east-west roadway, but follows a southwest-

northeast alignment through the study area, following the alignment of the Cape Cod Canal. All other

intersecting freeways (Route 25, Route 3, and Route 6 Mid-Cape Highway) are also functionally

classified as Principal Arterials under MassDOT jurisdiction. The Bourne Bridge and Sagamore Bridge

are under the jurisdiction of the Army Corps of Engineers.

Route 6 generally provides two lanes in each direction within the study area. The western end of the study

area is the elongated rotary intersection with the ramps to and from Routes 25 and 28. Route 6 is median

divided from the rotary to a signalized intersection with Nightingale Pond Road approximately ¼ mile

east of the rotary. A Hess gas station with a Dunkin’ Donuts is located on the north side of Route 6 in this

segment, but is restricted to right-in/right-out access from Route 6 westbound due to the center median.

Sidewalks are provided on both sides of Route 6 between Route 25 and Nightingale Pond Road. A solid

white edge line with a minimal edge offset is provided in both directions. The signalized intersection of

Route 6 and Nightingale Pond Road is a 4-way intersection with Nightingale Pond Road forming the

north leg and a campground access road forming the south leg. Nightingale Pond Road provides a two-

lane approach with a shared lane for left turns and through vehicles and an exclusive right turn lane. No

left turn lanes are provided on Route 6; left turns to Nightingale Pond Road or the campground are

accommodated from shared lanes. A crosswalk is provided across the west leg of Route 6 with

pushbuttons activating an exclusive pedestrian phase.

Route 6 Westbound at Edge Hill Road

Route 6 continues east approximately 1.4 miles to a signalized intersection with Edge Hill Road. This

segment of Route 6 continues to provide two travel lanes in each direction, and is undivided except for a

median on the approach to Edge Hill Road. Shoulders of varying width are provided along this segment,

but no sidewalks are provided. The topography of the area generally slopes towards the canal, which

creates upward slopes on the north side of the roadway and guardrail along a downward slope on the

south (canal) side of the roadway. A sweeping horizontal curve to the right accompanies a downhill grade

for westbound drivers in this segment. A history of crashes on wet roadway surfaces led to resurfacing

and drainage improvements in this area.

A reconstruction project at the intersection of Edge Hill Road included installation of the traffic signal

and construction of an eastbound left turn lane and medians on the intersection approaches. Edge Hill

Road approaches Route 6 from the north, and provides separate lanes for left and right turns. Edge Hill

Road and Nightingale Pond Road both provide access to an otherwise isolated residential neighborhood

and to Bournedale Elementary School. Scenic turn-outs are provided along the south side of Route 6 on

both sides of Edge Hill Road; medians extending from the intersection prevent turns into either turn-out

from Route 6 westbound. Oversized Signal Ahead warning signs are provided in advance of Edge Hill

Road in both directions, supplemented by flashing beacons.

The median dividing the east leg of Route 6 at Edge Hill Road extends approximately 800 feet from the

intersection. Route 6 is undivided from the end of this median to the signalized intersection at Bournedale

Road. A driveway to a gravel plant intersects Route 6 just beyond the end of the median; trucks typically

follow right-in right-out operation, although left turns to and from the driveway are legally allowed.

Route 6 between Edge Hill Road and Bournedale Road continues to provide two lanes in each direction,

with shoulders of varying width and no sidewalks. Businesses and minor side streets on the north side of

Route 6 approaching Bournedale Road have access from both directions of Route 6. Route 6 eastbound

approaching Bournedale Road provides two through lanes, an exclusive left turn lane to Bournedale

Road, and a right turn lane to a scenic turn out adjacent to the Herring Run Recreation Area. Route 6

westbound provides a left turn lane to the scenic turn out parking area, and two through lanes. This scenic

parking area adjacent to Herring Run Recreation Area is the only one within the study area accessible

from Route 6 westbound. Herring Pond Road intersects Route 6 approximately 750 feet to the east of

Road Safety Audit—Route 6 (Scenic Highway)—Bourne, MA Prepared by BETA Group, Inc.

Page 5

Route 6 Eastbound at Bournedale Road

Bournedale Road and forms a triangle with Bournedale Road and Route 6; traffic from Route 6 west uses

Herring Pond Road to access Bournedale Road rather that turning right at the signalized intersection.

Bournedale Road at the signal has a wide approach lane which separates into left and right turning lanes,

separated by a triangular island. Crosswalks are provided across the west leg of Route 6 allowing a

pedestrian connection to Herring Run Recreation Area, and across Bournedale Road. A sidewalk is

provided along the north side of Route 6 between Bournedale Road and Herring Pond Road. Illuminated

RED Signal Ahead signs are provided in both directions, although only the eastbound sign is mounted

overhead. It was noted that the westbound sign was ground-mounted due to wind load concerns.

A median begins just to the west of Herring Pond Road, prohibiting left turns onto Route 6 eastbound

from Herring Pond Road. This median continues along Route 6 from Herring Pond Road through the

series of ramps and signalized intersections connecting this segment of Route 6 with Route 3 and the

Sagamore Bridge. The ramp carrying Route 6 eastbound to the Sagamore Bridge is approximately ¾ mile

east of Herring Pond Road and forms the eastern end of the study area. Route 6 eastbound widens to

provide a deceleration area for the ramp, and continues to provide two through lanes east of the ramp.

Crash data provided by both State and local police and summarized by MassDOT show 31 crashes within

the study area from January 2009 to June 2012. A crash summary is included in the Appendix. The most

prevalent crash type are single vehicle crashes, comprising 55% of all crashes. Sixteen of 31 crashes were

noted to involve a hydroplaning vehicle, and 74% of crashes involved wet or snowy roadways. It was

noted that vehicles hydroplane on the downhill grade and horizontal curve westbound between Edge Hill

Road and Nightingale Pond Road, and that vehicles end up encroaching on the eastbound lanes or striking

the guardrail bordering the south side of the roadway. Wet roadway crashes have continued in the wake of

recent drainage and resurfacing improvements.

Speed regulation information was provided for Route 6 in Bourne. The speed regulation for the study area

was updated in 2006 and establishes a signed 50 mph zone generally between Nightingale Pond Road and

Bournedale Road. The established, posted speed limit reduces to 40 mph in the vicinity of the Route 3

and Route 6 ramps at the eastern end of the study area, and reduces to 35 mph west of Nightingale Pond

Road at the western end of the study area. The westbound speed limit further reduces to 25 mph

approaching the elongated rotary at Routes 25 and 28.

Audit Observations

Following a brief introduction to the RSA process and a summary of existing crash information, the audit

participants were asked to discuss safety issues for Route 6 (Scenic Highway). Audit participants viewed

a video recording of the corridor, and subsequently offered observations on safety issues. A summary of

those major safety considerations is as follows:

Hydroplaning – Hydroplaning is of significant concern along Route 6, as evidenced by the history of

crashes on wet pavement. The area of concern is shown in Figure 2. A number of contributing factors

were identified.

o Pavement Rutting – Route 6 was recently resurfaced in this area, but heavy truck traffic along

the corridor results in visible ruts, especially along the outside lanes. Pavement rutting can create

ponding channels, which increase the potential for hydroplaning when braking.

o Sheet Flow and Superelevation – It was noted that the westbound downhill slope approaching

Nightingale Pond Road results in significant sheet flow, and that this flow then stays within the

westbound lanes due to the superelevation. This sheet flow in the westbound lanes can promote

hydroplaning across the roadway.

o Ponding – The superelevation contains the water within the westbound lanes through the

horizontal curve shown in Figure 2, which then results in ponding during heavy rain events in

the westbound shoulder. Recent drainage improvements included additional catch basins in this

area, but ponding still occurs where basins are not present.

CONCERN

Damaged Guardrail along Route 6 eastbound

Speed – Driver speed along Route 6 was noted as a safety concern, and a contributing factor in wet

roadway crashes. Nine of 31 crashes cited “driving too fast for conditions”. The downhill grade of

Route 6 westbound approaching the curve before Nightingale Pond Road encourages driver speed,

and may cause a driver to brake to slow the vehicle, initiating hydroplaning

Lack of Shoulders – The lack of usable shoulders along Route 6 between Nightingale Pond Road and

Edge Hill Road was cited as a safety concern. The lack of shoulders reduces the amount of time that a

driver has to correct an errant maneuver. The guardrail along the eastbound lanes shows extensive

evidence of vehicle strikes, likely from westbound vehicles traveling across the eastbound lanes and

the limited shoulder available.

Red Signal Ahead Sign –The Red Signal Ahead sign for Route 6 westbound in advance of

Bournedale Road is ground mounted, reducing its visibility and effectiveness. It was noted that this

sign was post-mounted rather than overhead mounted due to concerns over wind loading.

Potential Safety Enhancements

After viewing the video recording of the corridor, audit participants were asked to discuss the safety

issues and 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,

mid-term, 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.

Table 2. Estimated Time Frame and Costs Breakdown Time Frame Costs

Short-term <1 year Low <$10,000

Mid-term 1–3 years Medium $10,000–$50,000

Long-term >3 years High >$50,000

Widen shoulders between Nightingale Pond Road and Edge Hill Road. It was noted that the planned

project will widen this segment of Route 6 and provide 4 foot minimum width shoulders. This is a

long-term, high cost improvement. It should be noted that a recent MassDOT directive requires 5 foot

minimum width shoulders for bicycle accommodation. The audit team discussed the need for bicycle

accommodation along Route 6, given the presence of the Cape Cod Canal Bikeway, which runs along

the canal parallel to Route 6. It was determined that despite the adjacent bike path, bicycle

accommodation should be provided along Route 6 if bicycles are legally allowed on the roadway.

Provide a center median between Nightingale Pond Road and Edge Hill Road. A center median is

proposed as part of the planned project, and would provide a continuous median from the rotary at the

Route 25 ramps to east of Edge Hill Road, with breaks only at the signalized intersections of

Nightingale Pond Road and Edge Hill Road. The median will break up sheet flow of stormwater, but

will require additional catch basins along the median edge. This is a long-term, high cost

improvement.

Provide proper superelevation through the horizontal curve between Nightingale Pond Road and Edge

Hill Road. Superelevation rates should meet AASHTO and MassDOT guidelines. Modifications to

existing cross slopes may require additional changes to drainage, in addition to those changes

required by median construction. This is a long-term, high cost improvement.

Construct drainage channels or swales on the north side of Route 6. Drainage swales in the area of

ponding concern would process stormwater and prevent ponding on the road. This is a long term,

high cost improvement.

Consider high friction pavement and subsurface investigation as part of pavement reconstruction

strategies. It was noted that the current project concept proposes resurfacing of Route 6 between

Nightingale Pond Road and Edge Hill Road, which will address current pavement rutting concerns. It

was suggested that further subsurface investigation should be conducted to determine if full depth

pavement reconstruction is required for all or part of the project segment, and that high friction

pavement may be appropriate for the downhill segment due to the heavy truck traffic along the

corridor. This is a long-term, potentially high cost improvement.

Continue speed enforcement along the corridor. This is a short-term and ongoing measure, the cost of

which is reduced enforcement elsewhere.

Install W8-5 “Slippery When Wet” sign on Route 6 westbound approaching the

downhill grade west of Edge Hill Road. This short-term, low cost improvement

will provide some form of warning until a more permanent fix is in place.

Consider upgrading the support structure for the illuminated RED Signal Ahead

sign on Route 6 westbound in advance of Bournedale Road so that the structure can

be mounted overhead. The sign is currently post-mounted due to concerns over

wind loading. This is a mid-term, medium 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 Bourne would be responsible for

implementing the recommended improvement. All improvements have an order of magnitude cost

assigned. The term “Project” refers to improvements that are assumed to be included or could reasonably

be accommodated as part of planned improvements.
