This case study is one in a series of documents that examines the use of Intelligent Transportation Systems (ITS) in work zones. More information on applications of ITS in work zones is available in the companion document, Intelligent Transportation Systems in Work Zones – A Cross-Cutting Study (Report No. FHWA-OP-02-025, EDL# 13600). This case study presents information gathered during interviews with key personnel involved with an Interstate 94 (I-94) reconstruction project in Detroit, Michigan. For the I-94 project, MDOT deployed a work zone Intelligent Transportation System (ITS) to help smooth traffic flow and reduce aggressive driving just prior to the transition into the construction area.
