• Abstract:
  This report analyses costs and benefits of Intelligent Transportation Systems (ITS) deployed by ; the Michigan Department of Transportation (MDOT). MDOT ITS focuses on traffic incident ; management and also provide Freeway Courtesy Patrol services. According to a survey in this ; study, radio, television and Mi Drive are the most frequently used travel information sources and ; 93 percent of motorists are at least somewhat trusting general dynamic message sign (DMS) ; information. The survey also revealed that the motorists assisted by the freeway courtesy patrol ; (FCP) are willing to wait at least 15 minutes longer than actual wait times and over 90 percent ; are satisfied with the quality and response time of the service. MDOT ITS reduced significant ; incident duration and delays. Thanks to the delay reduction, the benefit-cost ratio of statewide ; ITS deployment was estimated at 3.16. Among ITS devices in Michigan, CCTV and DMS were ; found to be very cost-effective. Accordingly, future investments should focus on DMS and CCTV ; installation, while deployment of MVDS needs further studies in conjunction with the coming ; wake of Connected Vehicle technology. ITS deployments were more cost-effective on locations ; with higher incidents and higher traffic volumes. This study identified highway segments with ; highest potential for positive ITS benefit.
