Borman Expressway ATMS Equipment Evaluation

摘要

An Advanced Traffic Management System (ATMS) is under development in northern Indiana by the Indiana Department of Transportation (INDOT) in conjunction with Hughes Transportation Management Systems. The study area comprises a sixteen mile segment of the heavily used Borman Expressway and its associated corridor; beginning at the Indiana/Illinois border and stretching east to the Indiana Toll Road interchange. The most important operational problem on the Borman is non-recurrent congestion, arising primarily through accidents and stalled vehicles. In order to mitigate the significant bottleneck delay problems due to non-recurrent congestion, INDOT is developing an ATMS for real-time incident detection and response on the Borman Expressway. INDOT has implemented a functional “mini” ATMS which incorporates small numbers of each of the components being considered for the future Borman ATMS, for validation and analysis of their capabilities. The prototype, or Phase I, encompasses three interchanges covering about three miles of the expressway. Phase I was designed and implemented to identify an architecture for Phase II ATMS can be developed using the basic Phase I architecture. However, experience with the Phase I system suggests certain issues must be addressed as the Phase II ATMS is planned.
