Title/Name/Summary
153rd Street and Ravinia Avenue Intersection Study
History
Currently programmed in the CIP Budget is the traffic signal installation at 153rd Street and Ravinia Avenue. There is $150,000 programmed for FY 2012 and $500,000 programmed for FY 2015. The intersection operates as an all way stop control. Whole Foods Market is scheduled to open in late 2012 and the LaGrange Road reconstruction is schedule to begin in mid to late 2013. In anticipation of the increase in traffic on 153rd Street due to the opening of the Whole Foods Market (located east of the intersection on the north side) and the increase in traffic on Ravinia to avoid the LaGrange Road construction it is recommended that a traffic study be completed in order to determine what level of service the intersection operates at today, if a traffic signal is warranted, and what the level of service will be after Whole Foods Market is open and a traffic signal is installed.
Christopher B. Burke Engineering, Ltd. (CBBEL) has prepared a proposal for the traffic study at this location. The study includes before and after Whole Foods Market traffic counts, before and after capacity analysis as well as a traffic signal warrant analysis. Geometric recommendations will also be included in a technical memorandum provided by CBBEL. CBBEL’s proposal for this work is $18,500.
Upon the completion of the traffic study a temporary traffic signal plan will need to be developed. Once the temporary signal is installed the Village will have the ability to monitor the intersection and make timing modifications based on the LaGrange Road construction project. The Village has received a quote from Western Utilities for the installation of existing temporary signal equipment the Village currently has available to use from the 143rd Street and LaGrange Road Intersection Improvement Project. The installation cost is $28,000 but may vary once an actual temporary signal design is completed.
