Overview

The northwest corner of Main Street (IL Route 83) and Central Road is being developed into residential apartments.  During discussions of the proposed development, nearby residents expressed ongoing traffic concerns such as cut thru traffic and speeding in the neighborhood.  Some also expressed concern that traffic generated from the apartments after construction will worsen the situation. 

The Village Board of Trustees directed the Public Works Department to gather traffic data on Pine Street, Wille Street, and Henry Street at the start of construction.  The data will then be compared to results of a second traffic study performed after tenants have moved into the new apartments.  The Public Works Department will provide the Village Board of Trustees the results of both studies and any recommendations for the neighborhood.

First Traffic Study

Electronic traffic counters were placed in June 2019 on the 0 block of N. Pine Street, 0 block of N. Wille Street, and 0 block of W. Henry Street.  A spreadsheet highlighting the traffic volume and speed data can be viewed by clicking on the link under Documents.  Traffic volume and speed data from a separate study performed on Wille Street and Henry Street in 2017 is also included in the spreadsheet. 

Traffic data was also collected at five intersections in June 2019: Central Road at Pine Street and Wille Street; and Henry Street at Pine Street, Wille Street and Main Street.  Public Works staff were stationed at each intersection from 7:00-9:00am and 4:00-6:00pm and recorded turning movements.  Neighborhood traffic patterns during the morning and evening peak hours were then determined based on the collected data.  A diagram highlighting several vehicle routes and corresponding estimated traffic volume can be viewed by clicking on the link under Documents

In summary, 

  • Current traffic volume and speeds do not qualify Pine Street, Wille Street or Henry Street for traffic calming measures per the Neighborhood Traffic Calming Program.
  • Daily traffic volume is within the typical range seen on residential streets in Mount Prospect
  • Average and 85th percentile speeds are within the typical range seen on residential streets in Mount Prospect
  • Traffic volume and speeds have not significantly changed since the 2017 study
  • The rate of southbound Main Street vehicles using Henry Street and Wille Street to Central Road is one vehicle per 24 minutes in the morning, and one vehicle per 3 minutes in the afternoon
  • The rate of southbound Main Street vehicles using Henry Street and Pine Street to Central Road is one vehicle per 24 minutes in the morning, and one vehicle per 9 minutes in the afternoon
  • The rate of eastbound Central Road vehicles using Wille Street and Henry Street to Main Street is one vehicle per 120 minutes in the morning, and one vehicle per 24 minutes in the afternoon
  • The rate of eastbound Central Road vehicles using Pine Street and Henry Street to Main Street is one vehicle per 20 minutes in the morning, and one vehicle per 15 minutes in the afternoon

Next Steps

  •  The Public Works Department is working with a consultant to design a crosswalk across Central Road at Pine Street.No engineering plans have been finalized at this time.Once completed, the Illinois Department of Transportation will need to review and approve the engineering plans prior to the Village proceeding with construction.Additional information on this project will be provided on this web page in the future.
  • The Public Works Department is evaluating the Pine-Russel-Henry intersection to determine if modifications should be made to improve STOP sign compliance.While there haven’t been any recorded accidents at the intersection in recent years, Staff noted a high percentage of vehicles not coming to a complete stop or vehicles stopping beyond the STOP lines.Changes to the intersection to improve STOP sign compliance may be considered as part of the Village’s 2020 Street Resurfacing Program.Additional information will be provided on this web page in the future.
  • The Public Works Department will perform a second traffic study after completion of the new apartments and most units are occupied by tenants.
