Road Safety Audit—Santilli Circle and Sweetser Circle
Prepared by AECOM
March 10, 2016
Background
The Federal Highway Administration (FHWA) 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. This RSA evaluates the Santilli Circle and Sweetser Circle
rotaries along Route 16 – Revere Beach Parkway (RBP) in Everett, Massachusetts. Route 16-RBP is
under the jurisdiction of the Department of Conservation and Recreation (DCR). A safety audit was
scheduled for these rotaries as part of the Massachusetts Environmental Protection Agency (MEPA)
approval process for the proposed Wynn Everett Project.
MassDOT has identified two Highway Safety Improvement Program (HSIP) crash clusters between 2011
and 2013 at Santilli Circle and one HSIP cluster at Sweetser Circle.
A key objective of the RSA is to identify both short-term and long-term safety improvements that can be
made throughout the corridor and or at the subject intersections.
Project Data
An RSA was completed for the rotaries on Thursday, January 28, 2016. The agenda for the RSA meeting
held at Everett City Hall is provided in Appendix A of this report. As shown below in Table 1, the audit
team consisted of a multidisciplinary team with representatives from state, regional and local agencies
providing expertise in the engineering, planning, and maintenance fields. Contact information for the
audit team members is provided in Appendix B of this report.
Within the email invitation sent on January 20, 2016 to each participant in the RSA, background material
was provided. This information included collision diagrams and crash data summaries for the study
locations. During the RSA meeting, these materials were reviewed as a group prior to the field visit to the
locations. During the RSA field visit, various safety issues were observed and identified. Following the
RSA field visit, the team returned to discuss additional concerns and potential solutions for the existing
safety issues.

The crashes and collision diagrams were based on crashes reported by Mass State Police between January
2011 and December 2013.
At Santilli Circle a total of 83 crashes were reported for the period between 2011 and 2013. Of these, 53
percent were rear-end crashes and 22 percent were angle crashes. Several rear-end crashes occurred when
motorists were yielding or failed to yield. A total of 35 percent of the crashes occurred between Noon and
4:00 PM. Two bicycle crashes were recorded. The month with the highest percent of crashes was
November (13 percent). The day with the highest percent of crashes was Tuesday (19 percent). Most
crashes occurred in daylight hours with clear weather conditions and dry road surface.
At Sweetser Circle a total of 56 crashes were reported for the period between 2011 and 2013. Of these, 56
percent were rear-end crashes and 21 percent were side swipe crashes. A total of 39 percent of the crashes
occurred between 2:00 PM and 8:00 PM. One bicycle crash was recorded. The month with the highest
percent of crashes was November (14 percent). A total of 16 percent of the crashes occurred on Tuesday,
Thursday and Saturday. Most crashes occurred in daylight hours with clear weather conditions and dry
road surface.

Santilli Circle
Santilli Circle is a rotary type intersection with signalized control where Route 16 intersects the rotary on
the east and west sides. Route 16 and the rotary are classified as a Principal Arterial by MassDOT. Route
16 west of Santilli Circle carries approximately 73,500 vehicles per day (2011). During the Friday PM
peak hour, approximately 6,340 vehicles enter the circle with a two-way traffic volume of approximately
5,500 vehicles on Route 16 west of the circle (2013). The posted speed limit on Route 16 is 35 MPH, but
25 MPH eastbound west of the circle. Route 16 is under the jurisdiction of the Massachusetts Department
of Conservation and Recreation (DCR). MassDOT has identified two HSIP crash clusters between 2011
and 2013 at Santilli Circle.
The traffic circle (rotary) itself consists of two lanes in one direction circulating counter-clockwise. The
following lanes and intersection controls are provided at each approach to the rotary:
•
•
•
•
•
•
Route 16 eastbound – three through lanes, one right-turn lane and one right-turn slip lane, signal
control
Route 16 westbound – two through lanes and one through-right lane, signal control
Santilli Circle Connector westbound – one lane entering rotary, Yield control
Mystic View Road northbound - one lane entering rotary, uncontrolled
Santilli Highway southbound – one lane entering rotary, Stop control
Santilli Circle interior – three lanes in each direction
The two traffic signals are coordinated with each other providing two signal phases. There are signalized
pedestrian crosswalks across Route 16 (west side) eastbound and westbound, which run concurrently with
the traffic movements. There are two pedestrian push button actuated signals: one on the westbound onramp on the west side of rotary and one on the eastbound right turn slip ramp on the west side.
Unsignalized pedestrian crosswalks are provided at the Santilli Highway entrance and exit roads; Santilli
Circle west of Kelvin Street connecting the MBTA bus stops; and at Kelvin Street. Sidewalks are
provided on the outside of the rotary on the north side between Mystic View Road and Kelvin Street.
There is an informal path worn through the center of the rotary on a northeast to southwest orientation.
No bicycle facilities are provided at Santilli Circle.
Figure 1 shows the Santilli Circle study area.

Sweetser Circle
Sweetser Circle is an unsignalized rotary type intersection. Route 16 under Sweetser Circle is classified as
a Principal Arterial by MassDOT. Route 99 and Main Street are classified as Urban Principal Arterials.
Route 99 south of Sweetser Circle carries approximately 40,400 vehicles per day (2005). During the
Friday PM peak hour, over 3,500 vehicles enter the circle with a two-way traffic volume of approximately
2,340 vehicles on Route 99 south of the circle (2013). Sweetser Circle is under the jurisdiction of the
Massachusetts Department of Conservation and Recreation (DCR). MassDOT has identified one HSIP
crash cluster between 2011 and 2013 at Sweetser Circle
The traffic circle (rotary) consists of one wide lane in one direction circulating counter-clockwise.
However, traffic generally form two lanes driving within the rotary. All approaches entering the rotary are
one lane, but traffic generally forms into two lanes under congested conditions. The following are the four
approaches to the rotary, all under Yield control:
•
•
•
•
Route 99 northbound
Route 99 southbound
Main Street southbound
Santilli Circle Connector eastbound
Except for crosswalks; there are no pavement markings within the rotary or on the approach roadways.
There is push button actuated pedestrian signal on the Route 16 eastbound on-ramp on the southeast
corner of the rotary. The signal provides flashing yellow and red ball beacons for both traffic and
pedestrians when actuated. A DCR crossing guard is located at this crosswalk for one hour during the
morning and afternoon peak hours. This crossing guard provides access for school children on Lower
Broadway to schools located on upper Broadway.
Unsignalized pedestrian crosswalks are provided across the Route 99 northbound and southbound, Main
Street and Santilli Connector roadways.
No bicycle facilities are provided at Sweetser Circle.

Audit Observations and Potential Safety
Enhancements
During the RSA meeting prior to the field visit, a brief introduction of the RSA process and a summary of
crash information was presented to the audit participants. Following this brief presentation, the members
of the audit team were asked to discuss the existing issues that may affect safety within the study area.
The audit team then visited the site as a group, at which time observations of various safety concerns and
deficiencies were identified and documented.
The audit observations identified and documented in this report, have been provided by audit participants
or commenter’s, and do not necessarily represent those of the report authors – AECOM. Comments made
by respondents have been reviewed to ensure the report is focused on current safety
concerns/recommendations within the study area, are relevant to plans for the corridor, and relate to the
goals of this RSA.
Provided below is a list of the safety concerns and issues that were identified during the RSA within the
study area.
Santilli Circle
Santilli Circle has a non-traditional rotary configuration with two traffic signals at the intersections with
Route 16. This presents unique issues in terms of safety and operations. Much of the MUTCD guidance
on roundabouts applies to this configuration. The issues observed are summarized in the following areas
which proceed counter-clockwise around Santilli Circle:
•
•
•
•
•
•
•
General
Santilli Circle Connector
Santilli Highway
Route 16 west
Mystic View Road/Gateway Center
Route 16 east

General
•
•
•
•
•
There are no bicycle facilities provided at Santilli Circle. Most pedestrian wheelchair ramps lack
detectable warning devices. The new Woods Memorial Bridge will include bicycle facilities.
There are no roundabout directional arrow signs.
There are no yield markings on the unsignalized rotary approaches of Mystic View Road
northbound and Santilli Circle Connector westbound.
Pavement distress such as rutting and shoving were observed.
Lack of guide signs directing motorists to roadway intersecting the rotary.

Santilli Circle Connector
•
•
•
•
The connection between the MBTA westbound bus
stop and the Best Buy store to the north is not ADA
compliant. The sidewalk abruptly ends and a staircase
does not connect to the sidewalk.
Sight distance is limited for westbound vehicles
approaching the crosswalk across Santilli Circle
Connector west of Kelvin Street. The crosswalk
distance is long across Santilli Circle Connector Road
and vehicle speeds appear to be high. The crosswalk
receives moderate volumes because it serves MBTA
bus stops on both sides of Santilli Circle Connector.
There are no pedestrian crosswalk signs and detectable Image 1: Lack of ADA sidewalk
to/from Best Buy parking lot
pedestrian warning devices.
There is a Yield sign for eastbound motorists making the right turn form the circle to Santilli
Circle Connector. The sign is not needed because there is no merging traffic.
There is no guide signage for motorists exiting the rotary onto Santilli Circle Connecter.

Image 3: Lack of Guide Sign to
Route 99
Santilli Highway
•
Vehicle queues back from signal blocking the Santilli Highway approach which makes it difficult
for motorists to maneuver around stopped vehicles.
Route 16 West
•
•
Westbound vehicles from rotary merge with westbound Route 16 vehicles. Vehicles weave to
align in downstream lanes. Lack of pavement markings and signage contribute to rear-end and
sideswipe crashes.
The pole-mounted traffic signal for westbound traffic exiting the rotary is out of order. There are
two overhead green arrow signal beacons which are confusing since there is only one designated
through lane. This signal is intended to be actuated only by a pedestrian pushing the button.

•
•
•
•
•
There is a long crosswalk across Route 16. Pedestrian walk times are not sufficient to cross
Route16 in one cycle. No countdown or accessible pedestrian signal (APS) signals.
High vehicle speeds on the Route 16 westbound merge combined with unexpected pedestrian
crossings is a potential safety issue.
There is an existing guide sign for eastbound motorists indicating right turn to Mystic View Road
and Santilli Circle to Rt. 99. However, the sign is located on the outside right turn lane and does
not give motorists enough warning to be in the inside right turn lane to access the Rotary and Rt.
99.
The pedestrian push button is broken on the west side of the eastbound right-turn slip ramp. The
pedestrian signal across the slip ramp should operate in a pre-emption mode since it is not
coordinated with traffic signal.
The southbound rotary approach queues make it difficult for vehicles from Santilli Highway to
enter the rotary and for vehicles to exit the rotary onto Route 16 westbound.

Mystic View Road/Gateway Center
•
•
•
There are no pedestrian facilities across Mystic View Road in the vicinity of Santilli Circle.
Sight distance for southbound vehicles from the Route 16 right turn slip lane onto Mystic View
Road is limited. Pedestrians may be crossing Mystic View Road in this area unexpectedly.
There is a worn pedestrian path at corner of Gateway Center that appears to indicate use.
Route 16 East
•
•
•
•
Northbound rotary approach has no arrow pavement
marking for inside lane.
Northbound signal shows a green ball and two
forward arrow indications, but should be three
forward arrows.
Northbound departure side lacks lane
markings/arrows for the three lane section.
Sight distance for westbound Route 16 traffic
approaching intersection is limited by horizontal
curve and heavy vegetation on the north side.

•
•
There is pavement width for two lanes for the northbound rotary right turn movement to Santilli
Circle Connector; however, there does not appear to be adequate geometry or lane designation for
two lanes.
Review use of the existing no left turn sign for northbound approach within the rotary. This sign
may cause confusion as it is on the far side where a left turn is allowed to the westbound.
Santilli Circle Interior
•
There is a well-worn northeast-southwest desire line pedestrian path across the circle. There are
no pedestrian crosswalks, wheelchair ramps, or signals where it crosses the circle and ramps on
the outside or Route 16 in the center.
Image 7: Worn Pedestrian Desire Line through Circle
Sweetser Circle
The issues observed are summarized in the following areas which proceed clockwise around Sweetser
Circle:
• General
• Main Street
• Upper Broadway
• Lower Broadway East
• Lower Broadway West
• Santilli Circle Connector
General
•
•
The rotary is missing standard signage for a rotary including chevron entrance signs, advanced
warning signs and combined One Way/No Left Turn.
Sweetser Circle is a wide roadway with little or no delineation of pavement markings. The
approaches to the circle are not striped, but vehicles often queue in two lanes. Motorists generally
drive in two lanes within the circle. However, the lack of markings exacerbates confusion when

•
vehicles merge and weave within the rotary and is the cause of
many sideswipe crashes around the rotary.
Vehicles weave between on- and off-ramps within the rotary at
relatively high speeds. This is due to the geometry at both the
entrance/exit ramps including deflection angles and large
circulating radius.
There are no bicycle facilities provided at Sweetser Circle.
However, bicycle lanes are provided on both sides of Lower
Broadway.
Some crosswalks are missing pedestrian crosswalk signs,
wheelchair ramps and detectable warning devices.
Main Street

Pedestrian crossing and yield signs are blocked by tree limbs
on Broadway westbound approach. The signs will be even less
visible when the tree leafs out.
A flashing yellow beacon is present on the approach; however,
no supplemental sign is provided.
Wheelchair ramp missing.

•
•
•
There is a gap in the guard rail between the outside lane and
sidewalk on the bridge.
Signal across on-ramp to Route 16 eastbound does not have
pedestrian signal heads and beacons utilizes older signal
operating standards with flashing yellow and red for traffic
and pedestrians. When the signal shows solid red for traffic,
circulating traffic in the rotary sometimes stops which creates
a safety issue.
The east side of the circle is used by students traveling to
school between Lower and Upper Broadway. A DCR crossing
guard is present between 7:00 and 8:00 AM and 2:00 and 3:00
PM.
Wheelchair ramps are missing.

Lower Broadway West
• Heavy traffic in the morning approaching rotary results
in backups into the rotary and vehicles stacking three
lanes wide at time. This also exacerbates the difficulty of
vehicles entering the rotary form Santilli Circle
Connector.
• There are no pedestrian crosswalk signs.
• Wheelchair ramps are missing.
Santilli Circle Connector
• The deflection angle for westbound traffic entering
circle is too large to slow down vehicles.
• There are no pedestrian crosswalk signs.

Potential Safety Enhancements
The Audit Team members offered potential safety enhancements that could be implemented to mitigate
the safety related observations that were noted in the previous section. Audit Team members were
encouraged to develop short, medium and long-term safety enhancements.
Santilli Circle
General
• Update all pedestrian signals to 16” heads with countdown signals and APS push buttons.
• Update wheelchair ramps to comply with ADA standards.
• Provide pedestrian crosswalk and advance warning signs at unsignalized crosswalks (see
MUTCD Section 2C.50).
• Install roundabout directional arrow signs (see MUTCD Section 2B.43).
• Provide bicycle accommodations where feasible. Evaluate a cycle track on the northern portion of
Route 16 and the northern section of the rotary.
• Provide yield lines for Mystic View Road and Santilli Circle Connector rotary approaches (see
MUTCD 3C.04).
• Install an additional guide sign on the Route 16 eastbound approach to the rotary directing
vehicles to Rt. 99.
• Any enhancements need to be coordinated with the planned improvements to the Wood Memorial
Bridge located west of Santilli Circle.
• A long-term solution of grade separating Rt. 16 was discussed.
Page 12
Road Safety Audit—Santilli Circle and Sweetser Circle
Prepared by AECOM
March 10, 2016
Santilli Circle Connector
• Narrow roadway width by adding curb extensions at bus stop crosswalk to improve motorist
visibility of pedestrians and encourage slower travel speeds approaching the rotary. Consider a
rectangular rapid flashing beacon. Trim trees and vegetation to improve sight lines.
• Construct ADA compliant access between the MBTA bus stop on the north side and the Best Buy
parking lot.
• Remove Yield sign on the eastbound departure from the rotary to Santilli Circle Connector.
• Provide guide sign from the circle northbound to Route 99 (see Image 3).
Route 16 West
• For the westbound ramp approach from the rotary, evaluate replace the two overhead and one
post-mounted green signal arrows with yellow flashing beacons. Repair post-mounted signal so it
is operable. It is noted that the DCR representative called to repair this signal at time of the Audit.
• Narrow or restripe the westbound ramp approach to one lane by reducing pavement width. This
will reduce the high number of rear-end crashes.
• Perform an analysis to evaluate the benefits of having the ramp movement and the Route 16
westbound through movement operate as separate signal phases.
• Replace the lane drop sign with a lane merge sign on the gore between the on ramp and Route 16
westbound mainline.
• Evaluate if the eastbound right turn slip lane can be eliminated. Right turning traffic would then
use the eastbound right turn lane at the intersection. This would reduce vehicle speeds
approaching Mystic View Road and eliminate the existing weave. It would also allow for
widening the existing sidewalk on the west side of the rotary.
• Repair pedestrian push button at the Route 16 eastbound right turn slip ramp crosswalk. It is
noted that the DCR representative called to repair this signal at time of the Audit. Evaluate that
this signal could operate on a pre-emption mode for pedestrians.
• Evaluate pedestrian signal times and adjust as necessary so adequate crossing time is provided
across Route 16 west of the circle.
• Provide two green forward arrow indications for the rotary movement southbound.
Mystic View Road/Gateway Center
• Evaluate the feasibility of new crosswalk across Mystic View Road. This may include options for
a rectangular rapid flashing beacon and curb extensions. Coordination will be needed with
Gateway Center.
Route 16 East
• Install “Signal Red Ahead When Flashing” sign for Route 16 westbound approaching the rotary.
This will alert motorists to stopped vehicles ahead as they approach around the horizontal curve.
• Install a new signal head on the left side facing the westbound Route 16 approach to the rotary.
• Remove vegetation on the Route 16 westbound approach to the circle to improve sight lines.
• Provide lane designation pavement markings in the rotary for the northbound approach to Santilli
Circle Connector.
• Provide three green forward arrow indications for the rotary movement northbound.
• Provide lane designation pavement markings for the northbound rotary movements between
Route 16 westbound and Santilli Circle Connector.
Page 13
Road Safety Audit—Santilli Circle and Sweetser Circle

March 10, 2016
Santilli Circle Interior
• Evaluate the feasibility of providing a sidewalk northeast-southwest through the circle. For longterm evaluate a pedestrian bridge across Route 16.
• Coordinate with the MBTA to determine if a bus route can serve Gateway Center to reduce the
number of pedestrian crossing the rotary.
Sweetser Circle
General
• Provide lane marking delineation and directional markings on approach lanes and within the
rotary to define travel lanes and encourage slower vehicle speeds (see MUTCD Section 3C.02).
• Provide “Keep Right” sign on splitter island at approaches to the rotary.
• Update wheelchair ramps to comply with ADA standards.
• Provide pedestrian crosswalk and advance warning signs at unsignalized crosswalks.
• Move pedestrian crosswalks back from the edge of circulatory roadway where feasible to prevent
vehicles from stopping in the rotary (see MUTCD Section 3C.05).
• Provide bicycle accommodations where feasible.
• Provide yield lines for all rotary approaches (see MUTCD 3C.04).
• Long-term measure is to evaluate intersection reconfiguration including reducing circular
diameter to modern roundabout standards
Upper Broadway
• Trim trees and vegetation blocking yield and pedestrian crossing signs on southwest Broadway
approach to rotary.
Lower Broadway East
• Reprogram signal to discontinue flashing red and yellow mode. Replace 8”signal heads with 16”
current standard. Long–term measure is to replace with countdown signals.
• Re-orient crosswalk so that it is perpendicular with the roadway to allow for shorter crossing
times and vehicles to stop outside of the rotary.
• Long-term measure is to widen sidewalks to provide separated bikeway (cycle track) or provide
bicycle lanes separated by barrier.
• Replace guardrail on inside circle of east bridge structure with pipe rail.
Santilli Circle Connector
• Realign on-ramps to provide sharper angle of deflection to slow vehicles entering the circle.
