APPROVAL OF MINUTES
Chairman Beening made a comment that after observing the parking situation at Lions Park
Elementary School, he no longer believed use of the Park District parking lot was a possible
solution to relieving some of the parking issues around the school. The Park District parking lot
is too far from the school. Commissioner Mitchell asked that his comment about the red light at
Rand Road and Ccmtral Road being out for five weeks be included in the August minutes.
Commissioner Mitchell, seconded by Chairman Beening, then moved to approve the minutes of
the regular meeting of the Safety Commission held on August 14, 2000. The minutes were
approved by a vote of 8-0.

CITIZENS TO BE HEARD
Carol Inserra, 215 S. Albert Street, expressed a concem with the traffic along Albert Street
between Central Road end Northwest Highway. Vehicles are moving quickly and use the street
as a cut through. Many children also live in the area. She would like to know the process of
getting Yield or Stop signs in the area. She thanked the Police Department for their presence out
there in the last month.
Chairman Beening suggested she work with her neighbors to get support and start a petition to
begin to identify end address the concerns. Traffic Engineer Lawrie could meet with a few
representatives to provide written materials to help in the petition process.
Officer Dahlberg provided a summary of the effort the Police Department has made to slow
motorists who travel on Albert Street.
3'anet Roy, 409 S. Albert Street, asked the possibility of turn restrictions along Mount Prospect
Road to reduce cut through traffic. Traffic Engineer Lawrie stated Staff could look into the
possibility. One of the negatives, however, is the problem could be simply moved to another
street and by placing turn restrictions at every intersection, residents cannot access their own
streets. Traffic Engineer Lawrie mentioned the Village is working with IDOT on reducing the
congestion at the Rand / Central / Mt. Prospect intersection which should have an effect on
reducing the amount of cut through traffic in the neighborhood.
Ms. Roy mentioned a parking problem on Albert Street near Northwest Highway by the
commercial business. The Village previously proposed to the residents widening the street to
provide parking spaces. A majority of the residents, however, were not in favor of the work at
the time. She asked that this issue be revisited.
.OLD BUSINESS
A) STATUS REPORT OF THE PROPOSED TRAFFIC CALMING IMPROVEMENTS ALONG
COUNCIL TRAIL
1) Background Information
At the August 14t~ Safety Commission meeting, it was approved to move forward on
implementing curb extensions on a trial basis at two intersections near Lions Park Elementary
School. During the month of September, Staff would solicit comments from nearby residents,
school administration and parents. The results of the study would be communicated to the
Safety Commission and Village Board in October.
Since the meeting, Staff has met With the Village Manager and received approval to install the
temporary curb extensions. Parking bumpers, asphalt and signs will be included in the design.
At this point, the use of wood chips and landscaping has been omitted. Since the temporary curb
extensions may be left in place until next summer, for maintenance reasons these amenities have
been left out. Staff will consider wood chips and landscaping in the final design should we
construct permanent curb extensions.
2
Staff has spoken with the Principal of the school, Kristine Cn-itzmacher, and also received her
support. Finally, Staff spoke with the Superintendent of School District 57, Maureen Hager, on
this subject. She expressed a concern with possibly creating traffic flow problems around the
school since parking problems currently exist. Information on curb extensions and a layout of
the proposal was provided to her. Staff has requested a meeting with her, the school and Staff
including the Police and Fire Departments on-site to resolve her concerns.
2) Discussion
Traffic Engineer Lawrie provided an update on this issue. Staff is still in the process of trying to
set up a meeting with the Superintendent to resolve all of her concerns. Until the Superintendent
is in support of the proposal, the Village will not proceed.
No further discussion took place on this issue.
NEW BUSINESS.
A) · KEQUEST FOR YIELD SIGNS AT THE INTERSECTION OF HI-LUSI AVENUE AND
BUSSE AVENUE
1) Background Information
Kesident Observations:
Ms. O'Toole says that motorists on Busse Avenue do not slow down through the intersection
assuming Hi-Lusi Avenue has Yield signs. Most of the other intersections in the neighborhood
have Stop or Yield signs. She has seen accidcmts and near accidents. She's not sure how many
motorists actually know the rules of the road at an unmarked intersection and, therefore, is
requesting Yield signs be installed on Hi-Lusi Avenue at Busse Avenue.
Staff Observations:
The Engineering Staffperformed a traffic study. The findings are as follows:
a) Accidents
A search of the accident reports indicated:
Year 1995 1996 1997 1998 1999 2000
(Aug)
Number of
Accidents 0 1 0 0 1 0
3
b) Speed Study
Representative speed surveys were performed on Hi-Lusi Avenue south of Busse Avenue and on
Busse Avenue west of Hi-Lusi Avenue between August 7th and August 9~. The average and 85~
percentile speeds are as follows:
average ~5~ %
Northbound Hi-Lusi 22 mph 27 mph
Southbound Hi-Lusi 23 mph .27 mph
Eastbound Busse 25 mph 30 mph
Westbound Busse 24 mph 29 mph
The speed limit on Hi-Lusi Avenue is 20 mph and on Busse Avenue is 25 mph. Based on the
results, there doesn't appear to be a significant speeding problem.
c) Traffic Volume
Traffic volume data was gathered in August. Based on the results, there are approximately 1360
vehicles per day that enter the intersection. 240 vehicles travel on Hi-Lusi Avenue and 1120
vehicles on Busse Avenue.
The maximum total vehicular volume entering the intersection from all approaches for the peak
eight hours during a recorded day was 800.
d) Survey Results
A total of 20 surveys were sent out in August 2000 to collect the residents' comments on this
request. 12 surveys (60%) were returned to the Village. Most of them indicated that vehicles
drive in excess of the speed limit on Busse Avenue.
e) Existing Traffic Control Signs
Traffic control signs adjacent to the intersection are as follows:
Prospect & Hi-Lusi (north) - 1-way Stop sign on Hi-Lusi
Evergreen & Hi-Lusi (south) - 2-way Stop signs on Hi-Lusi
Busse & I-Oka (east) - 2-way Yield signs on Busse
Busse & Wa-Pella (west) - 4-way Stop signs
f) Site Obstructions
Drivers approaching an uncontrolled intersection should have an unobstructed view great enough
to enable them, after perceiving a vehicle on the crossroad, to stop prior to reaching the path of
the other vehicle. This is called the stopping sight distance. The speed used to calculate the
stopping sight distance is the 85~ percentile speed. Based on field measurements and the
recorded speeds, sight obstructions exist at all four corners of the intersection.

Stop Signs
Though it wasn't requested, we felt it appropriate to determine whether Stop signs would be
warranted at the intersection. Stop signs are warranted when there are five or more reported
accidents of a type susceptible of correction by Stop sign installation in a 12-month period. Over
the past five years, there has been a total of two reported accidents.
Also, Stop signs are warranted when the minimum traffic volume entering the intersection from
all approaches is 500 vehicles/hour for an eight hour period ($00 x 8 = 4000 vehicles/8 hrs). The
traffic volume at this intersection (800 vehicles/8 hfs) is approximately 20% of the Stop sign
warrant.
When the 85-percentile approach speed of the major street traffic exceeds 40 mph, the minimum
vehicle volume warrant is 70% of the above requirements. The 85-percentile approach speed for
all directions do not exceed 40 mph.
Stop signs are not warranted based on the accident history, traffic volume and speed study at the
intersection.
Yield Signs
The study has shown Stop signs are not warranted at the intersection. However, it would be
appropriate to install Yield signs on the less-traveled street (Hi-Lusi Avenue) in order to clarify
the right-of-way.
Also, and more importantly, because of the possible difficulty of seeing opposing traffic based
on the sight obstructions near the intersection, Yield signs should assist in reducing the potential
for an ~ccident.
Recommendation:
Yield Sign Request
To clarify the right-of-way at this intersection,
The Village Traffic Engineer recommends:
2-way Yield signs on lti-Lnsi Avenne at Bnsse Avenne be installed.
2) Discussion
Diane O'Toole, 106 S. Hi-Lusi Avenue, came as the neighborhood representative requesting
Yield signs for the intersection.
Traffic Engineer Lawrie provided an overview of the traffic study including volume and speed
data. The study also included reviewing accident history and inspecting the intersection for sight
obstructions.
Chairman Beening asked that letters be sent to the home owners requesting trimming of their
trees and shrubs to eliminate the sight obstructions. He recognized the Village cannot require the
trees and shrubs to be trimmed since they are on private property.
Commissioner Bencic, seconded by Commissioner Nlitchell, moved to approve installing
Yield signs on Hi-Lusi Avenue at Busse Avenue,
The motion was approved by a vote of 8-0.
OTHER ISSUES
Chairman Beening asked that the Safety Commission discuss appointing a Vice Chairman. This
person's responsibility would be to take Over for the Chairman when he cannot attend a meeting.
Commissioner Mitchell nominated Commissioner Bencic because of his experience working for
the Village and the number of years living in Mount Prospect. Commissioner Bencic accepted
the nomination.
Commissioner Mitchell, seconded by Commissioner Bjork, moved to nominate Commissioner
Bencic as Vice Chairman of the Safety Commission.
The motion was approved by a vote of 8-0.
ADJOURNMENT
With no further business to discuss, the Safety Commission voted 8-0 to adjourn at 8:25 p.m.
upon the motion of Commissioner Mitchell. Commissioner Bencic seconded the motion.
Respectfully submitted,
Traffic Engineer
