Background
A Road Safety Audit (RSA) as defined by the Federal Highway Administration (FHWA) is “the
formal safety performance examination of an existing or future road or intersection by an
independent, multidisciplinary team.” An RSA qualitatively estimates and reports on all safety
issues and identifies opportunities for safety improvements for all roadway users. The
“conducting of RSAs at high-crash locations throughout the Commonwealth” is one of the many
strategies noted in the state’s Strategic Highway Safety Plan, which was developed in an effort to
reduce the number of crash-related fatalities and incapacitating injuries on roadways within
Massachusetts.
The Interstate Route 95 ramps with Storey Avenue (Route 113) were identified by the
Merrimack Valley Planning Commission as being one of the top locations for crashes within the
Merrimack Valley. According to the Merrimack Valley Metropolitan Planning Organization’s
(MPO’s) 2011 Regional Transportation Plan, this location experienced a total of 59 crashes over
a period of three years from 2006 to 2008. For the approximate 3,462 locations within the
Merrimack Valley that experienced crashes, this location is ranked as being number 23 in terms
of the overall crash frequency and number 21 in terms of Equivalent Property Damage Only.
Because the Interstate Route 95 ramp intersection locations are within the top five percent of
crash clusters in the Merrimack Valley region, it is eligible for the Highway Safety Improvement
Program (HSIP). MassDOT incorporated the RSA as a requirement for securing Federal funding
(HSIP funds) for safety projects. For these reasons, this intersection was chosen as the site of an
RSA by the Merrimack Valley MPO to help identify potential short-term and long-term safety
improvements that could be made if HSIP funding is received.

Project Data
The Road Safety Audit was conducted on November 19, 2012 for Storey Avenue (Route 113) at
the Interstate Route 95 ramps. As shown in Table 1, the audit team was comprised of state,
regional, and local agencies and included professionals from emergency response, engineering,
and planning.
Prior to this meeting, MVPC gathered, reviewed, and summarized the most recent pertinent
available information, including: crash data, traffic volume data, and traffic speed data. In
addition to the crash data summaries obtained from the MassDOT/RMV Statewide database,
MVPC also collected the actual crash reports, which show the narratives and crash diagrams,
from the Newburyport police and Massachusetts state police departments.
With input and assistance from Newburyport officials, MVPC selected the RSA team and chose
to meet at the City Hall. At the pre-audit meeting, MVPC discussed the process and goals for the
RSA, provided handouts of all pertinent information, presented the existing traffic, speed, and
crash data, and discussed any known related planned projects to the participants in order to
provide an introduction to project. The team then began to provide comments on the safety
issues, based on their knowledge of the intersection. MVPC recorded the comments.
Following the pre-audit meeting, the team conducted a site visit/audit, during which the previous
specific safety issues and concerns were pointed out by the RSA team and MVPC. Additional
safety issues were identified at the site and recorded by MVPC.
After the site visit, the RSA participants met in a post-audit meeting and the group discussed
potential countermeasures that had been identified during the RSA and any new countermeasures
that could be thought of during the meeting. The countermeasures, which were recorded by
MVPC, included short-term, intermediate-term, and long-term improvements. The State DOT
was identified at this meeting as the owner of all roadways in this study area and therefore is the
responsible party for the improvements and any necessary designs.

Project Location and Description
MVPC conducted an inventory of the existing ramp intersection geometry in May of 2012.
Traffic volumes were collected by Vanasse, Hangen, Brustlin, Inc. (VHB) in April and May of
2010, prior to the increase in volumes along Storey Avenue due to the closing of the Hines
Bridge over the Merrimack River for repairs. Below is a detailed discussion of the interchange
geometrics and traffic control features, a discussion of the daily and peak hour traffic volumes, a
review of the crash data, and an analysis of the existing operations. As of this writing, work is
complete on the Hines Bridge.
Geometrics and Traffic Control
Interstate Route 95
Interstate Route 95 (I-95) is part of the nation’s network of interstate highways and it runs
approximately 1,920 miles between Houlton, Maine at the Canadian border to the north and the
Coconut Grove neighborhood of Miami, Florida to the south. In the Northeast, the I-95 corridor
runs through some of the most densely developed and mature metropolitan areas of the country,
of which Boston is one of them. Approximately 92 miles of the highway lies within
Massachusetts, traversing the state from Salisbury at the New Hampshire state line to Peabody,
then circumferentially around the Boston metropolitan area, and finally from Canton to Attleboro
at the Rhode Island state line. North of Boston, the highway, which is owned and maintained by
MassDOT, serves interstate travelers as well as commuters traveling from northern suburbs to
the Boston and employment centers surrounding the city.
The highway provides four lanes of travel per direction that are separated by a center median
from its interchange with Route 1 in Peabody, to the south, up to and through its interchange
with Storey Avenue (Route 113) in Newburyport, to the north. Approximately 1,500 feet north
of the Storey Avenue ramps, the highway’s cross-section narrows. It decreases from eight to six
lanes as it is carried on the Whittier Bridge over the Merrimack River and then until it reaches
the ramps for Interstate Route 495 in Salisbury to the north. The Whittier Bridge is programmed
to be reconstructed (Project #601096) beginning in the summer of 2013 with work expected to
be completed by the summer of 2016. The bridge will be replaced with a wider cross-section of
eight lanes. The speed limit on Interstate Route 95, in the vicinity of Storey Avenue, is posted at
65 miles per hour (mph).
Storey Avenue (Route 113)
Storey Avenue (Route 113) is an east/west state owned roadway, 1.8 miles in length, which runs
from the West Newbury town line at the Artichoke Reservoir crossing to the west to its
intersection with Moseley and High Streets, to the east. Figure 1 presents a USGS map showing
the audit site locus along Storey Avenue as it passes over Interstate Route 95, which is located at
the approximate mid-point of the roadway. The roadway, which is functionally classified as an
urban principal arterial, widens from two lanes to four from the west as it approaches the ramps
with Interstate Route 95. East of I-95, the four-lane Storey Avenue (Route 113) is designated as

being part of the National Highway System (NHS) of roads. For eastbound travelers on Storey
Avenue, west of I-95, the speed limit is posted at 35 mph immediately east of Daniel Lucy Way.
East of I-95, it is also posted at 35 mph for eastbound travelers, immediately east of Russell
Terrace. The speed limit for eastbound travelers is posted at 30 mph immediately west of Park
Circle. For westbound travelers, the speed limit is posted at 35 mph immediately west of Park
Circle and at 50 mph immediately west of Hoyts Lane. These speed limits are consistent with
the limits that are noted in Special Speed Regulation #578B for the City of Newburyport. A
speed limit 35 is not present for eastbound travelers passing by Hoyts Lane. A speed limit 30
mph sign is not present for westbound travelers coming from High Street. Land uses fronting the
roadway are primarily residential west of I-95 and are primarily commercial retail east of I-95.

Storey Avenue (Route 113) at the Interstate Route 95 ramps
Interstate Route 95 was originally constructed in the early 1950s and it had an interchange with
Storey Avenue (Route 113) in Newburyport in a full cloverleaf style ramp system. In the mid
1970s, Interstate Route 95 was reconstructed and its alignment was shifted slightly to the west
and a new interchange was constructed with Storey Avenue to its present more compact slip
ramp style configuration, as presented in the aerial photograph of Figure 2. The City of
Newburyport and the Essex National Heritage Area maintain the “Little River Nature Trail”
along the old Interstate Route 95 northbound off-ramp and the old Interstate Route 95 alignment
that is partially paved. MassDOT has a driveway to its commuter Park and Ride lot along the
old Interstate Route 95 northbound on-ramp.
Through the Interstate Route 95 ramp system, Storey Avenue carries two lanes of travel per
direction that are separated by a raised center median island. The center median extends to the
commuter Park and Ride lot driveway intersection, which is located approximately 485 feet east
of the Interstate Route 95 northbound ramp intersection. The Interstate Route 95 southbound
ramp intersection is located approximately 880 feet west of the Interstate Route 95 northbound
ramp intersection. The Interstate Route 95 northbound and southbound ramp intersections, as
well as the commuter Park and Ride lot driveway intersection, are all signalized and the traffic
signal controllers are interconnected with one another along Storey Avenue. The signals run in
coordinated operation on a 100 second cycle during the weekday morning commuter peak period
and a 90 second cycle during the weekday evening commuter peak period. Clearance intervals
between signal phases for all of the signals are 3 seconds of yellow and 2 seconds of all-red time.
Of interesting note is the fact that the travel distance along Storey Avenue varies by direction
between the northbound ramp intersection and the commuter Park and Ride lot driveway
intersection. The distance between STOP lines at the signalized intersections is approximately
455 feet in the westbound direction and approximately 510 feet in the eastbound direction.
Therefore, it takes approximately one second more to travel in the eastbound direction and clear
the intersection than it does in the westbound direction for vehicles traveling at free flow speeds.
Passing the ramps along Storey Avenue, there generally is a distance of approximately eight feet
between the solid white travel edge lines and the curbing.
Sidewalks, approximately five feet in width, are provided along both sides of Storey Avenue.
The sidewalks have a bituminous concrete surface, except for a 300 foot section carried on the
bridge over the interstate highway, which has a cement concrete surface. The sidewalks are in
good condition. There are no crosswalks painted across the ramps or Storey Avenue. A
crosswalk, 7 feet in width, is painted across the commuter Park and Ride lot driveway.
Storey Avenue (Route 113) at the Interstate Route 95 southbound ramps
Traffic originating from or destined to the downtown side of Storey Avenue to the east can
access or egress Interstate Route 95 southbound by an on- and off-ramp that are opposite one
another and offset from one another (by approximately 50 feet). The traffic going onto or off of
one of these ramps is under signalized traffic control. There are two 12-foot wide travel lanes in
Page 5

Figure 2.
Aerial Orthogonal Photo of Storey Avenue at I-95 (Source: Pictometry, 4/04/12)
each direction of Storey Avenue at this intersection and one 12-foot wide exclusive left-turn
lane, which is approximately 515 feet in length, on the westbound approach for vehicles wishing
to access the on-ramp. The Interstate Route 95 southbound off-ramp splits at its base
approximately 130 feet from Storey Avenue by a delta shaped island into one exclusive rightturn off-ramp lane and two exclusive left-turn lanes that meet Storey Avenue perpendicularly.
Traffic in the right-turn lane onto Storey Avenue westbound is under YIELD-sign control, while
traffic in the two side-by-side left-turn lanes, which are a minimum of 13-feet in width, is under
signal control. Lane line extension pavement markings guide the traffic in the two left-turn lanes
through the intersection. Traffic heading eastbound on Storey Avenue and destined to Interstate
Route 95 southbound is channelized onto the on-ramp approximately 100 feet behind the STOP
line (and traffic signal control) by a large delta shaped traffic island.
Page 6
Road Safety Audit — Storey Ave. (Route 113) at Interstate Route 95 interchange – Newburyport, MA
Prepared by the Merrimack Valley Planning Commission
The traffic signal controller for the intersection operates under full actuation and, as mentioned
previously, is interconnected with the controller at the Interstate Route 95 northbound ramp
intersection. During commuter peak periods, this controller operates as part of a coordinated
system on a 90- to 100-second signal cycle in three phases with all phases called. Four traffic
signal heads are affixed to two 30-foot long mast arms with 20-foot tall supports and seven
signal heads are supported on three 10-foot tall signal posts at the intersection; two of which are
on the center median island tips. Beacons for emergency vehicle preemption of the signal sit on
top of the mast arms.
Storey Avenue (Route 113) at the Interstate Route 95 northbound ramps
The geometric configuration and traffic control of the Interstate Route 95 northbound ramp
intersection is nearly identical and a mirror reflection of the Interstate Route 95 southbound ramp
intersection. Like the southbound ramp intersection, there are two 12-foot wide travel lanes in
each direction of Storey Avenue at this intersection. Because this intersection is a reflection of
the southbound ramp intersection, on the eastbound rather than westbound approach, there is also
one 12-foot wide exclusive left-turn lane, which is approximately 515 feet in length, and which
is provided for vehicles wishing to access the northbound on-ramp. Traffic that enters this onramp or leaves the off-ramp, which is opposite the on-ramp and slightly offset from it, is under
signal control.
One of the other differences between this ramp intersection and the southbound one is that the
portion of the Interstate Route 95 northbound off-ramp for left-turning vehicles has only a single
left-turn lane, rather than two. This lane is a minimum of 15-feet wide. Another difference is
the traffic in the right-turn lane of the off-ramp is under STOP sign control, rather than YIELDsign control.
The traffic islands at the ramps of this intersection are slightly larger than the islands at the
southbound ramp intersection. The Interstate Route 95 northbound off-ramp splits at its base
approximately 200 feet from Storey Avenue, rather than 130 feet, by its delta shaped island into
the exclusive left-turn off-ramp lane and the exclusive right-turn off-ramp lane. Traffic heading
westbound on Storey Avenue and destined to Interstate Route 95 northbound is channelized onto
the on-ramp approximately 120 feet behind the STOP line, rather than 100 feet, by a large delta
shaped traffic island.
The traffic signal controller for the intersection is interconnected with the controllers at the
Interstate Route 95 southbound ramp intersection and the commuter Park and Ride lot
intersection and runs in coordinated operation during commuter peak periods. Like the
southbound ramp intersection, four traffic signal heads are affixed to two 30-foot long mast arms
with 20-foot tall supports. It should be noted that one of the signal heads for westbound traffic is
slightly rotated and does not face through traffic directly. Four more signal heads are supported
on three 10-foot tall signal posts at the intersection; two of which are on the center median island
tips. Emergency vehicle preemption beacons sit on top of the mast arms.

Storey Avenue (Route 113) at the Commuter Park and Ride Lot
MassDOT maintains a parking lot with approximately 615 marked parking spaces immediately
east of the Interstate Route 95 northbound ramp. People will park their vehicles in this lot and
use one of two private bus coach carriers to either commute to Boston or travel to Logan Airport.
C& J operates the lot and provides approximately 30 inbound and 30 outbound weekday bus
trips daily to/from downtown and the airport. The Coach Company provides approximately 6
inbound and 6 outbound daily bus trips to/from downtown Boston. Parking is free and is
allowed overnight for a maximum of 21 days. Observations showed that this lot sees good use
and on many occasions is over capacity with the staff of one of the coach companies moving the
overflow cars in a “valet” style parking to unmarked spaces.
The driveway for the parking lot uses the alignment of the old Interstate Route 95 northbound
on-ramp and it meets Storey Avenue from the north to form a three-way signalized intersection.
Storey Avenue has two 12-foot wide travel lanes per direction and a 130 foot long, 12-foot wide
exclusive left-turn lane for vehicles entering the lot from the Interstate 95 ramps and Storey
Avenue to the west. The left turn lane is protected from vehicles traveling in the opposite
direction by a raised center median strip that is covered in bituminous concrete. The center
median island continues on the east side of the intersection for another 200 feet where it
terminates and a short center two way left turn lane begins for nearby Russell Terrace and the
Mobil gas station. Traffic exiting the lot and using the driveway can use one 12-foot wide
exclusive left-turn lane or one 10-foot wide exclusive right-turn lane. Traffic flow direction is
separated on the driveway by a 100-foot long, 5-foot wide, raised center median island.
A crosswalk is painted across the commuter Park and Ride lot driveway, but not across Storey
Avenue.
The traffic signal controller for the intersection operates under full actuation and generally rests
on green for the Storey Avenue through traffic and will call a phase for Storey Avenue eastbound
left-turn lane (entering the parking lot) and for the lot driveway (exiting the parking lot) when
traffic is present. This signal controller is interconnected with the controller at the Interstate
Route 95 northbound ramp intersection and during commuter peak periods, it runs in coordinated
operation. Four traffic signal heads are affixed to two 35-foot long mast arms with 20-foot tall
supports with two facing each direction of travel for through traffic. Two signal heads are
supported on two 10-foot tall signal posts on the south side of Storey Avenue opposite the lot
driveway and both heads face the driveway. There is one signal head supported on a 10-foot tall
signal post that is located at the end of the center median island, east of the driveway, and the
head faces the Storey Avenue eastbound left-turn lane. Beacons for emergency vehicle
preemption of the signal also sit on top of the mast arms at this intersection.

Traffic Volumes
Traffic volume data used in this study was gathered in April and May of 2010, by VHB, for the
Hines bridge closing study (prior to its closing). Turning movement and vehicle classification
counts (TMCs) were conducted at the Storey Avenue signalized intersections, at and near the I95 ramps, during the weekday morning and evening commuter peak periods. Additionally, an
automatic traffic recorder (ATR) was placed by VHB on Storey Avenue (Route 113), east of
Low Street. Table 2 presents a summary of the daily and peak hour traffic volumes on roadways
at the intersection.

K-Factor is the percent of daily traffic occurring during the peak hour; expressed as a percentage. b
As shown in Table 2, there are approximately 15,800 vehicles per day (vpd) on Route 113,
immediately east of Low Street. West of Low Street, the daily volume is much greater, as much
of the traffic volume traveling to and from Low Street is originating from or destined to the
Storey Avenue and its interchange with Interstate Route 95.
Traffic flow on Storey Avenue (Route 113) predominates heavily in the eastbound direction
during the weekday morning peak hour and in the westbound direction during the weekday
evening peak hour, as shown in Table 2. This directional distribution is a good indication of the
importance of downtown Newburyport and the Storey Avenue corridor as an employment center.
Figure 3 presents the weekday morning and evening peak hour turning movement volumes. As
shown in Figure 3, for the approximate 1,119 vehicle-trips destined to Storey Avenue to the east
during the weekday morning peak hour, approximately 20 percent originate from Interstate
Route 95 to the south and approximately 46 percent originate from Interstate Route 95 to the
north. The inverse is true during the weekday evening peak hour with approximately 46 percent
of the 1,241 peak hour westbound trips destined to Interstate Route 95 northbound and
approximately 20 percent destined to Interstate Route 95 southbound.

Crash History
Historical traffic crash data was obtained for the study intersection from MassDOT’s statewide
crash database that was built with crash reports filed by police officers and vehicle operators
between 2008 and 2010 and sent to the Registry of Motor Vehicles (RMV). That data was
supplemented with data from the actual crash reports during that same period that were obtained
from the Newburyport Police Department and the Massachusetts State Police Department. The
data was reviewed over this three-year period to determine crash trends for the intersection.
Table 3 presents a summary of the crash report data.

According to the review of the data, there were a total of sixty-six (66) crashes over the threeyear period occurring at the Interstate Route 95 ramp system interchange with Storey Avenue
(Route 113), or an average of approximately twenty-two (22) per year.
Not only was the whole ramp system looked at collectively, but the intersections of the ramp
system were looked at discretely. The location where the greatest number of crashes occurred is
the signalized intersection of Storey Avenue with the Interstate Route 95 northbound ramps,
which experienced 28 crashes, followed by the Storey Avenue with the Interstate Route 95
southbound ramp signalized intersection, which experienced 21 crashes, followed by the Storey
Avenue signalized intersection with the commuter Park and Ride lot driveway, which
experienced 14 crashes.
The most predominant types of collisions occurring at the three signalized intersections were
rear-end type, which is a collision type typical for signalized intersections. Approximately one
half to three quarters of the collisions at those three signalized intersections were rear-end type
collisions.
Page 11
Road Safety Audit — Storey Ave. (Route 113) at Interstate Route 95 interchange – Newburyport, MA
Prepared by the Merrimack Valley Planning Commission
For those rear-end type collisions at the three signalized intersections where the location and
direction of travel is known from the police reports, there were a total of twenty-four crashes;
twelve occurring on Storey Avenue and twelve occurring on the Interstate Route 95 off-ramps,
as shown in the collision diagrams within the Appendix.
All but one of the twelve rear-end collisions on Storey Avenue occurred in the westbound
direction. Seven of the eleven westbound rear-end collisions occurred at the Park and Ride lot
driveway intersection and four occurred at the Interstate Route 95 northbound ramp intersection.
Of the total twelve rear-end type collisions that occurred at the Storey Avenue terminals of the
two Interstate Route 95 right turn off-ramp lanes, nine occurred at the northbound ramp and three
occurred at the southbound ramp. For ten of the twelve collisions, it is known whether a citation
was issued or not. For four of those ten, a citation was issued by the responding police officer
for the driver of the trailing vehicle for “failing to use care to stop”. Three citations were issued
at the I-95 northbound off-ramp and one at the southbound off-ramp.
There appears to be a relatively high percentage of collisions resulting in personal injury,
perhaps due to the travel speeds on Storey Avenue. Approximately 50 percent of the crashes at
the Park and Ride lot driveway intersection resulted in personal injury for an Equivalent Property
Damage Only (EPDO) rating of 42. Approximately 29 percent and 18 percent of the crashes at
the Interstate Route 95 southbound and northbound ramp intersections, respectively, resulted in
personal injury. The EPDO ratings for the Interstate Route 95 southbound and northbound ramp
intersections are 45 and 48, respectively.
Referring to the collision diagrams within the
Appendix for the three signalized intersections, one will see that for the eighteen collisions that
resulted in personal injury, most are the result of rear-end collisions. Only four are the result of
angle-type collisions between two vehicles, two are the result of a single vehicle running off of
the road, and one is the result of a vehicle striking a pedestrian.
More crashes occur after noon than in the morning, especially at the Interstate Route 95
southbound ramp intersection and the Park and Ride lot driveway intersection, however most
(approximately 80 percent) occurred during daylight hours. Approximately two-thirds of the
crashes involved vehicles traveling on dry roads.
There was one collision between a vehicle and a pedestrian at the Storey Avenue (Route 113)
intersection with the commuter Park and Ride lot driveway. The collision occurred in the dark at
4:18 in the morning with the pedestrian heading to the commuter lot and being struck by a
westbound traveling vehicle.
To get an idea of the relative safety of locations, the number of crashes at the intersection
locations for the intersections at and near the Interstate Route 95 ramps were also reviewed
against traffic volumes using those locations and then compared to the rate of crashes for other
similar type facilities. MassDOT reports that for the year 2011, the latest year available, there
are a statewide average rate of 0.81 crashes per million entering vehicles (mev) and a MassDOT
District 4 average rate of 0.78 crashes per mev for signalized intersections. Table 4 presents a

As shown in Table 7, this signalized intersection operates overall well within capacity at LOS A
during both the weekday morning and evening commuter peak hours. Through traffic on the
Route 113 approaches operates with little delay at LOS A during both peak hours as well.
However, the maximum (95th percentile) vehicle queue for the two westbound through lanes is
approximately eleven vehicles long and it occurs during the weekday evening peak hour. Traffic
turning left into the Park and Ride Commuter lot operates at LOS C during the weekday morning
peak hour and at LOS D during the weekday evening peak hour. There are no more than two
vehicles at one time waiting in the left-turn lane. Traffic turning from the Park and Ride
Commuter Lot driveway operates at LOS D during the weekday morning and evening peak
hours. The maximum number of vehicles stacked on the driveway is two vehicles.

Audit Observations and Potential Safety
Enhancements
The RSA team identified safety issues at the pre-meeting and also out at the audit site. Potential
safety enhancements were discussed out at the site and at the post audit meeting. Following is a
summary of the identified safety issues and the potential safety enhancements.
 Drivers of the trailing vehicles on the Interstate Route 95 off-ramp right-turn lanes are
sometimes inattentive to the leading vehicles that are stopped – As shown in the collision
diagrams within the Appendix, there were at least a total of twelve rear-end type collisions
that occurred at the Storey Avenue terminals of the two Interstate Route 95 right turn offramp lanes, with nine occurring at the northbound ramp and three at the southbound ramp.
For ten of the twelve collisions, it is known whether or not a citation was issued. For four of
those ten, a citation was issued by the responding police officer for the driver of the trailing
vehicle for “failing to use care to stop”. Three citations were issued at the I-95 northbound
off-ramp and one at the southbound off-ramp.
It was noticed at the audit that some drivers
of vehicles on the ramps turn their heads and
begin observing traffic on Storey Avenue
before the vehicle ahead of them departs the
ramp. Some of the vehicles advance without
the drivers returning their heads to check on
the vehicle in front of them. Should the
leading vehicle be stopped, while this is
happening, the result may be a rear-end
collision. In at least three of the state police
crash reports (I-95 northbound ramp crash
numbers 11, 14, and 18) within the Appendix, the responding officers reported from their
interviews that the trailing vehicle operator had thought that the leading vehicle operator had
driven away.
While this driver behavior is hard to control, the audit team recommended some safety
enhancements to either remind drivers of the
existing traffic control in place or to provide
alternative measures of traffic control. In the
short-term, it was recommended that advance
STOP and YIELD ahead (MUTCD W3-1 and
W3-2) warning signs be posted just on the
portion of the ramps where that traffic control
exists. This will let drivers on the ramps
know of the upcoming STOP or YIELD signs
located at the ramp terminals and remind
them of the need to stop or yield at those
locations. The placement of the advanced
Page 17
Road Safety Audit — Storey Ave. (Route 113) at Interstate Route 95 interchange – Newburyport, MA
Prepared by the Merrimack Valley Planning Commission
STOP and YIELD ahead (W3-1 or W3-2) warning signs should be carefully evaluated.
Because the primary traffic control of the intersections are the traffic signals, the W3-1 or
W3-2 signs must be placed in a way so drivers on the ramps approaching the signals do not
get the wrong message. The signs should be placed after the gore striping of the delta island,
where the ramp splits, but at least 100 feet prior to the control signs so only the vehicles
approaching the STOP or YIELD signs view the W3-1 or W3-2 signs. The signs should be
posted on both sides of the ramp to increase attention of the drivers.
In the mid-term, it was recommended that MassDOT incorporate the traffic on the ramp right
turn lanes into the intersections’ traffic signal control. This will involve the addition of two
new signal heads facing each of the right-turn ramps, with the signal heads tied into the
traffic signal control boxes. At each of the ramps, there could perhaps be one signal head
supported by a post or mast arm assembly on the right side of the ramp at its end and one
signal head supported on a post on the Storey Avenue center median island, opposite the
ramp. Alternatively, in the long-term, it was recommended that the ramp right-turning
vehicles be “squared off” by placing them where the left-turning vehicles presently stack and
including them in the traffic signal control. The existing portion of the ramps where the rightturning vehicles currently stack will be removed. Additionally, the portion of the ramp
where left-turning vehicles presently stack should be widened to accommodate both a leftturn lane and a right-turn lane. Traffic signal heads with green and yellow right-turn arrow
faces should also be added.
 Drivers of vehicles on the Interstate Route 95 NB off-ramp right-turn lane sometimes
treat the STOP signs as YIELD signs and roll through the STOP line – The police
officials at the audit noted that some people roll past the STOP sign and over the STOP line
on the Interstate Route 95 northbound offramp, while others do not.
Should
someone who rolls past the STOP sign be
behind someone who stops at the STOP
sign, then a rear-end collision may result.
As noted before, 75 percent of the rearend collisions occurring at the two
Interstate Route 95 off-ramp right turn
lanes occur at the northbound ramp where
the STOP sign is located. Approximately
40 percent of those collisions resulted in
the driver of the trailing vehicle being
issued a citation by the responding police
officer for “failing to use care to stop”. In the short-term it was recommended that MassDOT
affix visibility strips on the posts of the STOP signs at the end of the ramp. This should
further increase the visibility of the signs. As recommended before, MassDOT should
appropriately place advance STOP ahead (MUTCD W3-1) signs on the ramp to give advance
notice of the STOP signs. Perhaps the best way to remove this safety issue, as mentioned
before, is to incorporate the ramp right turn lane into the intersections’ traffic signal control,
which could be done in the mid-term. Two new signal heads will have to be added and face
the right-turn ramp. At each of the ramps, there could perhaps be one signal head supported
Page 18
Road Safety Audit — Storey Ave. (Route 113) at Interstate Route 95 interchange – Newburyport, MA
Prepared by the Merrimack Valley Planning Commission
by a post or mast arm assembly on the right side of the ramp at its end and one signal head
supported on a post on the Storey Avenue center median island, opposite the ramp.
Alternatively, in the long-term, it was recommended that the ramp right-turning vehicles be
“squared off” by placing them where the left-turning vehicles presently stack and including
them in the traffic signal control. The existing portion of the ramps where the right-turning
vehicles currently stack will be removed. Additionally, the portion of the ramp where leftturning vehicles presently stack should be widened to accommodate both a left-turn lane and
a right-turn lane. Traffic signal heads with green and yellow right-turn arrow faces should
also be added.
 Lack of visibility of signal heads facing Storey Avenue traffic, particularly in the westbound
direction – It was noticed during the audit
that there is older signal equipment at the
two Interstate Route 95 ramp intersections.
The signal heads are not very conspicuous
for a couple of reasons, which may result in
some westbound traveling vehicles noticing
a green or red signal indication and others
not, resulting in rear-end collisions. One of
the reasons for westbound travelers not
seeing the signal heads in the westbound
direction is because of the afternoon sun
glare partially washing out the indications
on the signal faces. It was also noticed that
one of the signal heads at the Interstate Route 95 northbound ramp is rotated and not directly
facing westbound traffic.
Firstly, the
misaligned signal head should rotated on
the mast arm support to properly face
westbound traffic. The audit participants
recommended placing backplates on the
signal heads with retroreflective markings
to increase their visibility at the ramp
intersections. It was stated that perhaps
moment calculations may need to be done
to find out whether the existing mast arm
supports can handle the additional wind
load from these backplates, prior to their
installation. It was further recommended
that an additional signal head be placed on the existing far side center median post to face
westbound traffic at the Interstate Route 95 northbound ramps. This
signal head will supplement the two signal heads that are supported on
the mast arm, thereby increasing the visibility of the green and red
indications. The City’s engineer recommended in the long-term that the
geometry of the I-95 NB ramp intersection be reconfigured to extend the
median westward some 20 to 40 feet and move the westbound STOP bar
up. This will draw stopped westbound drivers closer to the signal heads for better visibility.
Page 19
Road Safety Audit — Storey Ave. (Route 113) at Interstate Route 95 interchange – Newburyport, MA
Prepared by the Merrimack Valley Planning Commission
 Westbound travelers view green light at I-95NB ramp and proceed through a red light at the
Park & Ride Lot – Audit participants expressed some concern for the drivers of vehicles
heading westbound on Storey Avenue
and stopped at a red light at the Park
and Ride lot driveway intersection.
Some of those drivers will notice a
green light at the next intersection
downstream (Interstate Route 95
northbound ramp) and proceed while a
red light indication still glows for the
Park and Ride lot driveway intersection.
This has the potential for resulting in
some rear-end collisions. To keep
drivers from noticing the downstream
signal green indications while red
indications glow at the Park and Ride
lot driveway intersection, audit participants recommended installing
some technology so that the signal faces on signal heads will focus green
indications on westbound drivers at the Interstate Route 95 northbound
ramp only. The preferential technology mentioned was horizontal
louvers on the green signal faces to focus the green on the westbound
direction near the ramp. Alternatively, optically programmed signal
faces could be used to focus the green indications on the drivers as they
near the Interstate Route 95 northbound ramp.
 Lack of pedestrian crossing across Storey Avenue near the Park and Ride lot – During the
three-year study period, there was one collision between a vehicle and a pedestrian, who was
attempting to cross Storey Avenue to get to the Park and Ride lot early in the morning, before
sunrise. The pedestrian was struck by a westbound traveling vehicle shortly after stepping off
of the center median island between the
Park and Ride lot driveway and the
Mobil gas station.
The pedestrian
sustained injuries. Audit participants
noticed that while there is a crosswalk
across the Park and Ride lot driveway,
there is no marked crosswalk across
Storey Avenue for pedestrian use at this
location.
This Park and Ride lot
intersection is a place where pedestrians
from nearby residential developments,
like Russell Terrace, cross to access the
commuter bus service provided at the
Park and Ride lot. It is also a location,
City officials noted, where a future bike trail, known as the Whittier trail, will come from the
Page 20
Road Safety Audit — Storey Ave. (Route 113) at Interstate Route 95 interchange – Newburyport, MA
Prepared by the Merrimack Valley Planning Commission
north to meet the existing Little River nature trail to the south, across Storey Avenue.
Coupled with this future intersection of walking/biking trails is the future housing that is
presently being built on an extension of Russell Terrace. It is
therefore anticipated that there will be even more pedestrian
crossings in the future. It was recommended that a crosswalk
be provided across Storey Avenue with sidewalk ramps at each
end that are well lit by nearby street lighting. There should
also be new push-button actuated pedestrian signal heads that
are located at each ramp and are tied into the traffic signal
controller. The crosswalk should be painted across Storey
Avenue, east of the Park and Ride lot driveway with a refuge area for pedestrians halfway
across on the center median island. This will require that pedestrian ramps are constructed
on the median.
 Friction created by traffic turning into and out of the many corridor driveways – It was noted
immediately prior to the site walk that there are many curb cuts for commercial uses along
Storey Avenue east of the commuter
Park and Ride lot driveway. Traffic
turning into and out of these curb cuts
causes some friction to traffic traveling
through on Storey Avenue.
Audit
participants thought that the section of
the Storey Avenue corridor where these
curb cuts exist should be examined in
further detail with some possible
recommendations for improving safety.
The recommendation, therefore, was to
place Storey Avenue corridor under
study to consider how to manage the
vehicular access and egress from the
multiple developments between the Park and Ride lot and Low Street. It was further
recommended that the Merrimack Valley Metropolitan Planning Organization charge its
planning staff with this task.

Summary of Road Safety Audit
All of the safety issues and their potential safety enhancements were discussed in the previous
section. Table 8 provides a summary of the potential safety recommendations that were
discussed by the audit team. The recommendations are categorized in order of safety payoff with
their associated cost, time frame and responsible agency.
Safety payoff estimates are subjective and may be based on the relative percent of crashes that
may be reduced by the enhancement; for example, low (<30%), medium (31% to 70%), and high
(>71%). The time frame is categorized as short-term (<1 year), mid-term (1 to 3 years), or longterm (>3 years). The costs are categorized as low (<$10,000), medium ($10,001 to $50,000), or
high (>$50,001).

Appendix F. Intersection Operations
Analysis Methodology and Results
OPERATIONS ANALYSIS METHODOLOGY Level of Service
A primary result of capacity analyses is the assignment of level of service to traffic facilities
under various traffic flow conditions. Level of service is a qualitative measure describing
operational conditions within a traffic stream and the perception of these conditions by motorists
and/or passengers. A level of service definition provides an index to the quality of traffic flow in
terms of such factors as speed, travel time, freedom to maneuver, traffic interruptions, comfort,
convenience, and safety.
Six levels of service are defined for each type of facility. They are given letter designations from
A to F, with level-of-service (LOS) A representing the best operating conditions and LOS F
representing the worst.
Since the level of service of a traffic facility is a function of the traffic flows placed upon it, such
a facility may operate at a wide range of levels of service, depending on the time of day, day of
week, or period of year.
Signalized Intersections
The six levels of service for signalized intersections may be described as follows:

LOS A describes operations with very small delay; most vehicles do not stop at all.

LOS B describes operations with relatively small delay; however, more vehicles stop
than LOS A.

LOS C describes operations with higher delays. Individual cycle failures may begin
to appear in this level. The number of vehicles stopping is significant at this level,
although many still pass through the intersection without stopping.

LOS D describes operations with delay in the range where the influence of
congestion becomes more noticeable. Many vehicles stop and individual cycle
failures are noticeable.

LOS E describes operations with high delay values. Individual cycle failures are
frequent occurrences.

LOS F describes operations with high delay values that often occur with oversaturation. Poor progression and long cycle lengths may also be major contributing
causes to such delay levels.
Evaluation Criteria
Evaluation criteria used in the capacity analyses are described below.
Signalized Intersections
Levels of service for signalized intersections are calculated using the operational analysis
methodology of the latest Highway Capacity Manual. The capacity analyses for these facilities
measures the average delay to drivers from signal control. This method assesses the effect of
signal type, timing, phasing, progression, vehicle mix, and geometrics on delay. Level-ofservice designations are based solely on the criterion of calculated control delay, also known as
signal delay. Control delay includes the initial deceleration delay, queue move-up time, stopped
delay, and final acceleration delay. Delay can also be a measure of driver discomfort,
frustration, fuel consumption, and increased travel time. Table A-1 summarizes the relationship
between level of service and delay. The tabulated delay criterion may be applied in assigning
LOS designations to individual lane groups, intersection approaches, or to entire intersections.
