• Abstract:
  A Freeway Management System (FMS) employs various tools to manage a freeway to increase throughput and reduce delay ; without additional lanes. The FMS acquires data from the roadway and process these data to identify and respond to ; problems. If some aspects of the data are unreliable, then the response decisions will likely be faulty. ; This study evaluates the performance of the first phase of the Columbus Metropolitan Freeway Management System ; (CMFMS) along roughly 14 miles (22.5 km) of I-70 and I-71. The system became operational at the end of 2001. The tools ; developed and the evaluation are intended to both provide a better understanding of the operation of the facility and to help ; guide future investments in the CMFMS and other FMSs. ; The initial objective of this study was to evaluate the performance of the CMFMS. In the course of the evaluation this effort ; developed calibration tools and performance measures that should also prove useful for ongoing operations. The study ; specifically develops a suite of performance monitoring tools both to assess the performance of instrumented freeways and the ; reliability of the surveillance system. It also provides a comprehensive overview of the given traffic monitoring system for ; practitioners, allowing them to optimize the system. In the course of this work we integrated information from many sources ; to meet multiple objectives for system management and monitoring. Although presented in the context of the Columbus ; system, the tools should be generalizable to most freeway surveillance systems.
