Road Safe
ety Audit – Easttham: Route 6 at Governor Prence Road
Background All levels of governmentt— local, regiional, state, and federal—
—have been considering
g
locations wh
here crashes are most sev
vere for man
ny years. Sevveral years ago the natio
onal
consensus was that theree should be goals to redu
uce crashes, and in the 2005 federall
legislation: Safe, Accoun
ntable, Flexiible, Efficien
nt Transporttation Equitty Act: A Leegacy
for Users (SA
AFETEA-LU
U), there wass more emph
hasis on imp
proving high
hway safety along
with a dedica
ated funding
g program—
—the Highwayy Safety Imp
provement Program (HS
SIP).
The latest federal legisla
ation: Movin
ng Ahead forr Progress in
n the 21st Ceentury (MAP
P-21),
signed into law on July 6, 2012, has consolidated
d many high
hway programs while
retaining thee Highway Safety Impro
ovement Proggram (HSIP
P) as one of th
he five core
highway pro
ograms.
In an effort to reduce thee number off crash-relateed fatalities and incapaccitating injurries,
Massachusettts developed a Strategicc Highway S afety Plan in
n 2006. The mission of the
Safety Plan is to “Develo
op, promote, implement,, and evaluaate data-drivven,
multidiscipliinary strateg
gies to maxim
mize safety f or users of the roadwayy system.” One of
the many strrategies noteed in the Safety
f
Plan is to
o “conduct Road Safety Audits (RSA
A) at
high-crash lo
ocations thro
oughout thee Commonweealth.” MasssDOT incorp
porated the RSA
as a requirem
ment for securing Federa
al funding (H
Highway Saffety Improveement Progrram
[HSIP] fund
ds) for safetyy projects.
The Federal Highway Ad
dministratio
on (FHWA) d efines a Ro ad Safety Au
udit (RSA) aas the
formal safety
y examinatio
on of an exissting or futurre road or in
ntersection by an
independentt, multidiscip
plinary team
m. The purpo
ose of an RSA
A is to identtify potentiall
safety issuess and possiblle opportuniities for safetty improvem
ments while considering all
roadway useers.
The Cape Co
od Commissiion, serving as the region
nal planningg agency for the fifteen towns
on Cape Cod
d, has review
wed many tra
ansportation
n locations o
over the yearrs during varrious
processes, in
ncluding the Regional Trransportatio
on Plan, the Transportatiion Improveement
Program, an
nd Developm
ments of Regiional Impactt, considerin
ng the existin
ng safety issues
and potentia
al improvem
ments. In add
dition, the C CC began lo
ooking at speecific safety
locations ann
nually throu
ugh safety stu
udies and Ro
oad Safety Audits (RSAss). A portion
n of
the federal HSIP funds are allocated
d for improveements to th
he region’s highest crash
h
locations.
Introduction
n
The Town off Eastham ha
as 5,646 resiidents as of t he 2010 Un
nited States Census of
Population, and begins the outer Cape Cod arm that includees the Cape Cod Nationaal
Seashore. Many historicc properties and businessses line the main roadw
way through the
town, now ca
alled Route 6 and part of the Nation
nal Highway System. Ass with most Cape
Cod towns, there are visiitors in town
n, particularrly in the sum
mmer month
hs, resulting in
about 25,000 people in town. Largee numbers off additional visitors travverse Route 6
through Eastham on thee way to the three other o uter Cape C od towns. Route 6 in

In March 20
012, CCC stafff presented a safety upd

(RSA) locations to the Cape Cod Join

TC), and thee
resulting 2012 RSA locattions selecteed by the CCJ
CJTC includeed the Routee 6 intersectiion
with Govern
nor Prence Road in Easth

ntersection has long beeen a concern of the
Town of Easstham, with many previo

of bicyclists and pedestrrians crossing Route 6 in
n the vicinityy.

CCC staff preepared a gra

on. The crassh reports weere requesteed
from the Tow

Police Deparrtment. Thee crash data were review

ped.
The crash diiagram, sum

The Town off Eastham was contacted
d for a list off RSA particiipants in Jully 2012, and
d the
Road Safety Audit was scheduled wiith MassDOT

The Road Sa

dnesday, Jully 18, 2012, beginning around
10:00 a.m., at the Eastha

Route 6 is a major roadw
way cutting through Easstham, a statte highway with local acccess,
and is functiionally classiified as an Urban Extenssion of a Rurral Principall Arterial. Route
6 on Cape Co
od is also deesignated as part of the N ational Higghway System
m (NHS). The
Road Safety Audit is focu
used on Rou
ute 6 and thee Governor Prence Road
d intersection
n
area.
The RSA Tea
am reviewed
d the crash diagram, the crash summ
mary, the traaffic volumess, and
discussed th
he existing co
onditions. Additional crrash reports and the speeed regulations
were provideed during th
he team meetting.
There were 12 crashes frrom 2009-20
011 on Routee 6 near or at the interseection with
Governor Prrence Road in Eastham, with four injjury crashess and no fataal crashes. Of the
injury crashees, 50% weree angle and 50% were siide swipe craashes. Overall crashes by
type are 42%
% of the crash
hes were sin
ngle vehicle c rashes, 25%
% were anglee, 25% side sswipe,
and 8% rear-end crashess.
The intersecction has beeen a concern of the Town
n of Eastham
m for some tiime, and thee
District 5 Offfice of MassDOT has ma
ade minor im
mprovementts in sight diistance, and
performed signal warran
nt analyses for the interssection. A Turning Movvement Coun
nt
(TMC) was performed in
n August 20110. An addittional signal warrant anaalysis was
performed by CCC staff, in March 20
011. A signaal warrant haas not been met, so far. Both
the TMC datta and the sig
gnal warran
nt analysis weere brought to the RSA team meetin
ng,
and both aree included in
n the Append
dices.
The regulato
ory speed lim
mit for Routee 6 in Easthaam is 40 milles per hour in both directions
for most of Route 6 in th
he town. Thee MassDOT Highway Sp
pecial Speed Regulation
#7579-C, pro

DOT Safety, states:
“Westbou

0.24 miles at 25 miles per hour to the O
Orleans Town Line.
Eastbound: Thence easterly in Easstham; 0.16 miles at 25 miles per hour
5.94 miles at 40 miles per hour to the W ellfleet Town

Observatio
on: It was mentioned th

Another obse
ervation wass that
while travelliing southbou

painted on the lane soutth of the

Enhanceme
ent: Consid
der

The right turrn arrows directing
traffic to exitt should be
