PROJECT DESCRIPTION

Hampton, Lenzini and Renwick, Inc. (HLR) conducted a planning study for the Southern Illinois Metro Planning Organization (SIMPO) to evaluate 36 signalized intersections located between IL 13/127 in Murphysboro and Fair Street in Marion. HLR's traffic engineers conducted an inventory of the existing traffic signal and communications equipment at each of the 36 locations and determined the necessary equipment upgrades. Additionally, we researched national best practices for Automated Traffic Signal Performance Measures (ATSPM), which represents a newer approach to improving traffic operations and safety. Based on our findings, we provided recommendations for implementing an appropriate ATSPM system for this region.
