The I-35W traffic management system has been in operation for over seven years. The purpose of the project was to implement and evaluate the Bus-on-Metered Freeway System. A number of reports have been published documenting the design details, system hardware and software, system operation and evaluation of the Bus-on-Metered Freeway concept. A listing of these reports is presented in the Appendix. Appendix also includes a list of reports dealing with incident detection and/or incidents impact on capacity. One of the specific objectives within the system framework was to quickly detect incidents occurring on the freeway and provide information to the appropriate response agency so that freeway capacity reducing and hazard causing incidents could be
removed as soon as possible.
The purpose of this study is twofold: first, available incident records accumulated on the I-35W freeway traffic management system will be analyzed to develop a comprehensive view of the types and quantities of incidents that have occurred. Second, the incident data base and companion volume and occupancy data will be used to determine the impact of "typical" incidents and the impact of the total incident problem. Included in the report is an analysis of incident types detected, mode of incident detection, duration of incidents, and incident response activities.
