Cicero Retail Center Traffic Impact Study, Cicero, IL

Regina Webster & Associates served as a subconsultant to McDonough Engineering, Inc., to provide a Traffic Impact Study of a proposed Retail Center to be located on Cicero Avenue between 31st Street and 32nd Street in Cicero, Illinois. The purpose of the study was to determine whether Cicero Avenue and the adjacent streets near the proposed development will be adversely impacted by the construction of the Retail Center. The study provided an assessment of the traffic impacts of the Retail Center, which will be completed over a period of 5 years. Included in the analysis were the roadway network, traffic volumes, trip generation and distribution, and a capacity analysis. The study also evaluated the traffic operation on Cicero Avenue and identified possible roadway improvements to support the traffic generated by the site. RWA collected weekday and Saturday peak hour traffic volumes on Cicero Avenue at the intersections of 31st and 32nd Street. An estimate of site-generated traffic for the same time periods was developed based on proposed land uses, utilizing trip-generation rates from the Institute of Transportation Engineers (ITE) Trip Generation Manual. Using turning-movement counts, RWA projected directional distribution based on an analysis of existing traffic patterns in the area and conducted a capacity analysis at every intersection to determine the actual level of service (LOS). RWA made recommendations for location and geometry of drives and performed a traffic signal warrant analysis.
