Last fall, the Village delivered to you and your neighbors a Resident Information Bulletin regarding a traffic study performed along Pine Street, Wille Street and Henry Street. The purpose of the study was to gather vehicle data before completion of the new apartments at Central Road & Main Street. Results of the traffic study can be found on the Village web site at www.mountprospect.org/pine-wille-henry-study. And per the direction of the Village Board of Trustees a second traffic study will be performed after tenants have moved into the new apartments.
Part of last year’s traffic study included observing traffic at the Pine-Russel-Henry intersection. We noted that many motorists do not come to a complete stop, particularly northbound traffic on Pine Street. The STOP sign is positioned far from the intersection making it difficult for motorists to see other vehicles entering the intersection. Even though there haven’t been any recorded accidents at the intersection in many years, the Public Works Department has developed a plan that is expected to improve STOP sign compliance, slow vehicles, and enhance safety at the intersection.
A concept plan is shown below. The center island will be slightly expanded, STOP signs on Pine Street and Russel Street moved closer to the intersection, and pavement markings added to guide motorists through the intersection. The work has been included as part of this year’s Street Resurfacing Program. Construction is expected to begin in a few weeks, weather depending. Initial work will include removing the center island curb, relocating the drainage structures, and pouring the new center island curb and sidewalk. Relocating the STOP signs, installing the pavement markings, and restoring the center island with topsoil and grass will complete the work. Residents will have access to their driveways throughout the project and there will not be interruption to mail delivery or garbage pick-up.
Work is tentatively scheduled to begin the week of May 25. With construction being completed by the end of June 2020.
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.
- 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
- 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.
