I-35W and I-94 Traffic Management System have been in operation since 1974. As of December 1979, the TMS operation included six principal functional subsystems. These are (1) a 24 camera closed circuit television network (2) 38 ramp meter signals, (3) eleven express bus and/or carpool meter bypass ramps, (4) a motorist information program including changeable message signs, lane control signals, highway advisory radio and a traffic grade information sign, (5) the Traffic Management Center and (6) an incident detection and response program. The purpose of this study was twofold: first, available incident records accumulated on the TMS were 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 was 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.
