A. HIGHLAND STREETTRAFFIC STUDY
1) Background
A traffic accident on Highland Street between Maple Street and Elm Street involving a vehicle
and pedestrian prompted a traffic study performed by the Engineering Division. On September
2, 2016, a child ran across the street midblock in front of a vehicle and was struck. The low
speed/impact collision did not result in any significant injuries to the child. Nearby residents,
however, voiced their concerns that vehicles often speed on Highland Street and use it as a cut
through to avoid the Rand -Elmhurst -Kensington intersection. The Engineering Division was
tasked to gather vehicular volume and speed data on Highland Street to determine if the street
qualifies for traffic calming measures per the Village's Neighborhood Traffic Calming Program.
Current Traffic Regulations
1. Parking is prohibited between 2:00am and 6:00am on all Village streets.
2. Besides the overnight parking ban, there are no other parking regulations on Highland Street.
3. The speed limit on Highland Street is 25 mph.
4. The intersecting neighborhood streets along Highland Street are controlled with STOP signs.
Highland Street is controlled with STOP signs at Maple Street and is uncontrolled at Emerson
Street and at Elm Street.
5. Highland Street has full access at both Main Street and Rand Road.
Current Layout
1. Highland Street between Main Street and Rand Road is approximately 29' wide (back -of -curb
to back -of -curb).
2. The segment is four blocks totaling % mile.
3. The segment is classified as an east -west neighborhood collector street.
4. On -street parking is permitted on both sides of Highland Street.
2) Traffic Data Collection
Volume & Speed Data
Two traffic counters were placed on Highland Street during the week of October 10, 2016. One
was placed east of Emerson Street and one west of Elm Street. In summary,
Highland Street east of Emerson Street
Average Daily Traffic —1568 vehicles
Peak morning hour (7:00am — 8:00am) —155 vehicles
Peak evening hour (5:00pm — 6:00pm) —182 vehicles
Average speed — 26 mph
85th percentile speed — 31 mph
Highland Street west of Elm Street

Parking Data
Staff inspected the street on eight separate occasions and inventoried the number and location
of parked vehicles on Highland Street. Days included weekdays and weekends, and times
included morning, afternoon and evening. Overnight parking on Highland Street is only
permitted based on an individual request basis. The Police Department reports overnight
parking on Highland Street is occasionally requested and permitted, but is not a regular
occurrence. In summary,

Resident Survey
As part of the study, surveys were sent to 36 residential and business properties along Highland
Street between Main Street and Rand Road to solicit their input on this issue. A total of 9
surveys (25%) were returned to the Village.
Analysis
Per the Neighborhood Traffic Calming Program, the recorded average speeds of 24 & 26 mph
along Highland Street fall below the minimum 30 mph to qualify for traffic calming measures.
The recorded 85th percentile speeds of 29 & 31 mph also fall below the minimum 34 mph.
Highland Street, therefore, does not qualify for traffic calming measures based on recorded
speeds.
Per the Neighborhood Traffic Calming Program, the average daily traffic volumes of 1568 & 1752
vehicles along Highland Street exceed the minimum 1000 vehicles to qualify for traffic calming
measures. The peak hour traffic volumes of 182 & 217 vehicles also exceed the minimum 120
vehicles. However, since Highland Street is considered a collector street, traffic calming
measures are only considered if a high pedestrian generator is adjacent to the street. Typically,
this is a school, church or park where enhancing pedestrian safety is the primary goal of a traffic
TSC Meeting Page 3 of 6 January 9, 2017
calming project. In this case, Maplecrest Townhomes does generate pedestrian activity,
particularly with owners parking on Highland Street. While Maplecrest Townhomes is not a high
pedestrian generator, given the high density of residents on a short stretch of roadway, it would
be appropriate to consider measures that would enhance pedestrian safety and alert motorists
of the residential surroundings.
On -street parking is evident but minimal throughout the day. Evenings and weekends tend to
see more on -street parking compared to weekday mornings and afternoons. A majority of the
on -street parking appears to be associated with the Maplecrest Townhomes. The two outer
blocks (between Route 83 & Emerson Street and between Elm Street & Rand Road) saw more
on -street parking on the south side of the street adjacent to the single family residential
properties. The two inner blocks (between Emerson Street & Elm Street) saw more on -street
parking on the north side of the street adjacent to the multi -family properties. Based on Staff's
observations, on -street parking could be limited to one side of the street, if appropriate, without
impacting Emerson Street, Maple Street or Elm Street.
There have been only four recorded crashes since 2011 along Highland Street. Two crashes
involved parked vehicles, one was construction -related, and one was the vehicle -pedestrian
accident that prompted this study. There have been no crashes involving two moving vehicles
or crashes that would raise concerns at a particular intersection. Overall, the crash frequency
along Highland Street is low.
5) Recommendations
Highland Street is a collector street and, as such, traffic should not be diverted to other
neighborhood streets. However, engineering measures could be implemented to make
motorists more aware of the residential surroundings and enhance pedestrian safety. And while
the traffic data showed typical speeds for a residential street, engineering measures could have
a secondary benefit of slowing the higher individual vehicle speeds.
1. Limit on -street parkins; to one side of the street — Highland Street experiences above
average traffic volume for a neighborhood street (although typical for a collector street) as it
has direct connection to Route 83 and Rand Road. It also experiences consistent on -street
parking, primarily because of Maplecrest Townhomes. To limit pedestrians in the roadway
walking to and from parked vehicles, it is recommended to only allow on -street parking on
the side of the street that experiences more parking. For the two outer blocks, it would be
the south side of the street. For the two inner blocks, it would be the north side of the
street. This alternating pattern may also slow vehicle speeds through intersections as travel
lanes shift.
2. Install bump -outs at the Highland Street & Maple Street intersection — Curb extensions or
"bump -outs" are an effective traffic calming measure to enhance pedestrian and vehicle
safety at an intersection. They are used to slow traffic, reduce the crossing distance for
pedestrians, increase Stop sign compliance, and prevent on -street parking near the
intersection to improve visibility. The Village has installed several bump -outs with success
including on Burning Bush Lane, Wheeling Road, and Lincoln Street.
3. Narrow the travel lanes with pavement markings — With limited on -street parking and no
pavement markings, motorists may perceive wide travel lanes that can lead to higher
vehicle speeds. Narrowing the travel lanes to 10' with a combination of a yellow centerline
and a white parking line can confine vehicles to a limited space resulting in slower speeds.
Lincoln Street and Meier Road are examples of streets that have seen lower vehicles speeds
after adding a yellow centerline and white parking lines.

4. Install signs & pavement markings to slow traffic and remind motorists of the residential
surroundings — The word SLOW painted on each travel lane and a corresponding SLOW sign
in advance of the multi -family properties would remind motorists of the residential
surroundings. Similar SLOW signs have been installed on See Gwun Avenue with a positive
effect of reducing vehicle speeds. Additional Stop signs or lowering the speed limit are not
recommended based on the results of the traffic data and crash reports.
5. Install signs to deter cut through traffic in the neighborhood — NO THRU TRAFFIC signs at
Rand Road and at Main Street can reduce the traffic volume on Highland Street. Such signs
are not enforceable by the Police Department but have shown to be effective at other
locations in the Village.
6. Continue Police Department enforcement of the speed limit and Stop signs, and utilize the
speed feedback trailer to slow traffic — Periodic education and enforcement efforts are
effective in maintaining safe driver behavior. They can be done before and after a traffic
calming project.
6) Discussion
Vice Chairperson Morgan asked Traffic Engineer Lawrie to present the Engineering Division's
report. Traffic Engineer Lawrie provided the Commission with background information on this
issue and stated the Engineering Division's recommendations.
Commissioner Prosperi raised a concern with alternating the parking restrictions from block to
block. He asked if motorists would have sufficient distance to adjust to the shifting centerline
through an intersection. Traffic Engineer Lawrie said that it did meet standard design
guidelines. Commander Smith also expressed concern with the shifting centerline.
Commissioner Prosperi suggested restricting parking along the south side of the street for all
four blocks to provide a consistent centerline alignment. Traffic Engineer responded the
proposed design tried to minimize residents crossing the street to get to their vehicles based on
the current parking pattern. He concurred restricting parking to the same side of the street
would eliminate the shifting centerline concern.
Commission members noted that on -street parking was primarily along the two interior blocks
adjacent to Maplecrest Townhomes and questioned whether parking regulations were
necessary along the two outer blocks. In particular, Commission members did not want to
eliminate parking in front of the Moose Lodge if their parking lot could not accommodate all of
their patrons.
Mark Wesby, 122 E. Highland Street, thanked the Commission for discussing the issue. He
commented the Moose Lodge parking lot is not typically full. Traffic Engineer Lawrie said
throughout the study, which included observations during the evening, staff did not see the
parking lot full. Commission members agreed that on -street parking associated with the Moose
Lodge may only be seen during special events. There was general consensus to not add parking
regulations on the two outer blocks.
The Commission discussed the proposed bump outs at the Highland Street & Maple Street
intersection. Traffic Engineer Lawrie said their purpose is to prevent vehicles from parking close
to the intersection making pedestrians crossing the street more visible. They also shorten the
crossing distance for pedestrians. Traffic Engineer Lawrie pointed out that one of the concerns
from the resident survey was motorists not stopping at the STOP signs. He said the bump outs
allow the STOP signs to be moved closer to a driver's line -of -sight often increasing STOP sign
compliance. Commissioner Keane expressed his support for them.

the Commission would next be presented to the Village Board for their consideration. With
their approval, the Engineering Division would then develop construction drawings and
incorporate the project into the street resurfacing program this summer. A post -study would be
performed in the future and the findings presented to the Commission.
Commissioner Keane made a recommendation to approve the following:
1. Prohibit parking on the south side of Highland Street between Emerson Street and Elm
Street at all times.
2. Install pavement markings as proposed on Highland Street between Emerson Street and Elm
Street.
3. Construct bump outs at the intersection of Highland Street and Maple Street.
4. Install NO THRU TRAFFIC and SLOW signs as proposed.
5. Continue enforcement of the speed limit and STOP signs by the Police Department.
6. Perform a post -study after implementation and present the findings to the Commission.
The motion was seconded by Commissioner Prosperi.
The motion was approved by a vote of 7-0.
COMMISSION ISSUES
At the last meeting, Chairperson Kuehlthau reported a sight obstruction at the intersection of Route 83
& Henry Street. Traffic Engineer Lawrie reported that the tree in question has been trimmed to improve
the visibility for motorists.
ADJOURNMENT
With no further business to discuss, the Transportation Safety Commission voted 7-0 to adjourn at 7:55
p.m. upon the motion of Commissioner Tortorello. Commissioner Keane seconded the motion.
