Zone 7 Traffic Study
|
|
|
Summary
Zone 7 is an area bounded by Northwest Highway to the north and east, Central
Road to the south, and the western Village limits. The area has single and
multi-family housing with commercial development along Central Road. Melas Park
and the Central Community Center are within Zone 7.
The traffic study in Zone 7 has focused on implementing two programs: the
Residential Speed Limit Program and Residential Intersection Traffic
Control Program. The Residential Speed Limit Program involves
reviewing the speed limit on each street. This program is being handled by the
Engineering Staff. Speed data has been collected through the use of mechanical
traffic counters and information has been gathered on each street in the
neighborhood to assist in the study. Of the 1.6 miles of streets in Zone 7, 0.5
miles (31%) are currently posted 25 mph and 1.1 miles (69%) are unposted (30 mph
speed limit per Illinois law). Based on the traffic study, it is recommended
the entire 1.6 miles of streets in the neighborhood have a 25 mph speed limit.

The Residential Intersection
Traffic Control Program is being handled by the traffic engineering
consulting company KLOA, Inc. of Rosemont, Illinois. They have gathered traffic
volume data throughout the neighborhood and have taken measurements at each of
the 7 intersections in Zone 7. Overall, their recommendations include an
increase in the number of stop signs.

Speed Limit Study & Recommendations
Studies have shown that most
motorists will drive at a speed which is safe and reasonable. The modern
practice of setting speed limits at this level actually results in the lowest
accident experience. Interestingly enough, artificially lowering speed limits
has little effect on the speed at which motorists will actually drive making
traffic law violators out of even the most careful motorists. A speed limit set
too low can lead to tailgating, improper passing and reckless driving while a
speed limit set too high can foster unreasonable speeds for a neighborhood.
The Village is striving to see an increase in obedience to the speed limits
resulting in safer streets. This means setting consistent and reasonable speed
limits in a neighborhood. The objective, therefore, of the Residential Speed
Limit Program is to evaluate and determine the appropriate speed limit of each
residential street under the Village’s jurisdiction. Each street is to be
studied based on accepted engineering practices, conformity with the IDOT Policy
on Establishing and Posting Speed Limits and the criteria established in the
Residential Speed Limit Program. To review the streets neighborhood by
neighborhood, Staff has divided the Village into 18 “traffic zones”. This is the
study of Zone 7.
Zone 7 is bounded by Northwest Highway to the north and east, Central Road to
the south, and the western Village limits. The neighborhood has approximately
1.6 miles of streets under the Village’s jurisdiction and contains Melas Park
and the Central Community Center.
The goals of this study were to: (1) gather vehicle speed data along collector
streets and representative residential streets, (2) gather operational
characteristics for each street, (3) evaluate each street based on the
established criteria, and (4) make a determination of the appropriate speed
limit for each street within Zone 7. Operational characteristics include the
number of access points (driveways & intersecting streets), location of
sidewalk, parking restrictions, and accident history along a particular street
under review. Based on the Engineering Staff’s detailed study, the
recommendations are highlighted in the table below. It should be noted that
since there are no schools within Zone 7, none of the streets qualified for a
school speed limit zone.

Intersection Traffic Control Study & Recommendations
The basic purpose of a stop or yield sign is to define who has the right-of-way
at an intersection. They are not to be used to control speeding as studies have
shown unwarranted signs lead to a high rate of disobedience and can actually
cause higher speeds after the sign as motorists’ look to “make up for lost
time.” Unwarranted signs can also instill a false sense of security for
pedestrians, especially children, and can increase the potential for an
accident.
The Village is striving to see an increase in obedience to our traffic control
signs resulting in safer intersections. This means only stopping traffic before
entering an intersection when it would otherwise be unsafe. The objective,
therefore, of the Residential Intersection Traffic Control Program is to
evaluate and determine the appropriate traffic control at each intersection
under the Village’s jurisdiction. Each intersection is to be studied based on
accepted engineering practices, conformity with the Manual on Uniform Traffic
Control Devices and the criteria established in the Residential Intersection
Traffic Control Program. To review the intersections neighborhood by
neighborhood, Staff has divided the Village into 18 “traffic zones”. This is the
study of Zone 7.
Zone 7 is bounded by Northwest Highway to the north and east, Central Road to
the south, and the western Village limits. The neighborhood has 7 intersections
under the Village’s jurisdiction and contains Melas Park and the Central
Community Center.
The goals of this study were to: (1) gather vehicle volume data along each of
the streets in the neighborhood, (2) inspect and take measurements at each of
the intersections, (3) review the accident history at each intersection, (4)
evaluate each intersection based on the established criteria, and (4) make a
determination of the appropriate traffic control for each intersection within
Zone 7.
To assist in the evaluation process, a few guidelines have been established by
the Village:
- Intersections will be reviewed on both an individual basis and
neighborhood wide basis
- Only stop signs will be considered as a form of traffic control, not
yield signs
- Stop signs will only be installed on one of the two intersecting streets
unless the data supports the need to control both streets
Based on the detail study performed by the Village’s consultant, KLOA Inc.,
the recommendations are highlighted in the table below.
