• Abstract:
  Problem: The Ohio Department of Transportation (ODOT) ; deployed the first phase of the Columbus Metropolitan ; Freeway Management System (CMFMS) along 14 miles ; (22.5 km) of I-70 and I-71. The system includes loop ; detector stations every 1/3 mile (0.5 km), ramp meters, 4 ; changeable message signs (CMS), and an integrated ; traffic management center (TMC) to coordinate different ; government agencies and the media. The system became ; operational at the end of 2001. This study evaluates the ; performance of the first phase to both understand the ; operation of the facility and to help guide future ; investments in the CMFMS and other FMSs across the ; state of Ohio. The second phase build-out is currently ; under construction and is scheduled to be completed in ; 2006. ; Although the primary objective of this study is to ; evaluate the performance of the CMFMS, the effort ; developed calibration tools and performance measures ; that should also prove useful for ongoing operations. ; Data for this evaluation were collected on the mainline ; and ramps using the CMFMS loop detectors, dedicated ; probe vehicle runs and Central Ohio Transit Agency ; (COTA) automatic vehicle location (AVL) system on ; transit vehicles in the corridor. This study provides ; quantitative and qualitative results such as: travel times, ; speed data, traffic volume, and traveler delay. The study ; 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.
