Summary

Zone 11 is bounded by Central Road to the north, Busse Road to the east, Golf Road to the south, and the western Village limits. The neighborhood is primarily made up of single family homes and contains Holmes Junior High School, Forest View Elementary School and Clearwater Park.

The traffic study in Zone 11 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 Division. 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 12.0 miles of streets in Zone 11, 2.8 miles (23%) have a posted 20 mph speed limit, 2.6 miles (22%) have a posted 25 mph speed limit and 6.6 miles (55%) have an unposted speed limit of 30 mph (per Illinois law). Based on the traffic study, it is recommended all streets have a speed limit of 25 mph.

 

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 77 intersections in Zone 11. Overall, their recommendations include an increase in the number of Stop signs and elimination of the use of Yield 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, the Engineering Division has divided the Village into 18 “traffic zones”. This is the study of Zone 11.

Zone 11 is bounded by Central Road to the north, Busse Road to the east, Golf Road to the south, and the western Village limits. The neighborhood has approximately 12.0 miles of streets under the Village’s jurisdiction and contains Holmes Junior High School, Forest View Elementary School and Clearwater Park.

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 11. 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 Division’s detailed study, the recommendations are highlighted in the table below.

 

The Engineering Division also evaluated the two schools within the neighborhood, Holmes Junior High School and Forest View Elementary School, to determine those streets that should be posted a school speed limit zone.  Along those streets there would be a 20 mph speed limit during school hours when pedestrians are present.  The tables below shows those streets within the neighborhood that are recommended to be posted 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, the Engineering Division has divided the Village into 18 “traffic zones”. This is the study of Zone 11.

Zone 11 is bounded by Central Road to the north, Busse Road to the east, Golf Road to the south, and the western Village limits. The neighborhood has 77 intersections under the Village’s jurisdiction and contains Holmes Junior High School, Forest View Elementary School and Clearwater Park.

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 11.

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.
 

Traffic control at 40 intersections are recommended to have no change while modifications at 37 intersections are recommended as follows: 

•  One (1) intersection that currently has Stop signs on one street is recommended to have Stop signs in all directions (add Stop signs)

• Thirty-one (31) intersections that currently have no traffic control are recommended to have Stop signs on one street (add Stop signs)

• One (1) intersection that currently has a Stop sign on one leg of four-way intersection is recommended to have Stop signs on one street (add Stop sign)

• Two (2) intersections that currently have Yield signs on one street are recommended to have Stop signs on one street (add Stop signs)

• Two (2) intersections that currently have Stop signs on one street are recommended to have Stop signs on the opposite street only (no change in number of signs)

Open House

Before formally presenting the recommendations to the Village Board of Trustees for approval, residents in the neighborhood will be invited to an Open House.  This Open House will be an opportunity for residents to review the recommendations with Staff and ask questions in an informal setting.  The Open House will be held in the Multipurpose Room at Holmes Junior High School (see map below) on Monday, February 25^th.  Come anytime between 6:00pm & 7:30pm.  Those residents living within Zone 11 have been mailed a brochure detailing the programs and inviting them to the Open House. 

The Village encourages residents to attend the Open House and provide us feedback before any final decisions are made.  After review of the public comments, the final recommendations for both programs are scheduled to be presented to the Village Board of Trustees for approval at the April 15, 2008 Village Board Meeting.
