摘要：	Traffic incidents are the primary cause of non-recurrent congestion in urban areas, resulting in reductions in roadway capacity due to crashes, vehicle breakdowns, and other events. In addition to contributing to congestion and delay, incidents can result in significant safety hazards to other motorists, as well as first responders. In response to these adverse impacts, many communities have initiated incident management programs that detect and respond to incidents and restore freeways to full capacity by clearing the incident scene as soon as possible. Such programs play an important role in the operation of the transportation system and require collaboration and efficient communication among various agencies, including fire and rescue, police, towing and recovery, transportation engineers, and freeway service patrols. In the Detroit metropolitan area, the Michigan Department of Transportation (MDOT) operates a Freeway Courtesy Patrol (FCP) program as part of its larger freeway incident management program from the Michigan Intelligent Transportation Systems (MITS) Center in downtown Detroit. The MITS Center maintains a series of databases that detail freeway operations, as well as the activities of the FCP. This report details the activities from the second year of a two-year study aimed at assessing freeway operations in metropolitan Detroit. During the first year of this study, a software interface was developed to combine data from these various sources. These data include traffic flow information obtained from roadside microwave sensors, incident response data collected by FCP operators, and roadway geometry data. This research involves the development of a series of duration models to assess how various factors affecting the time required to clear freeway incidents. Various model formulations are compared and the transferability of model results across freeway segments is assessed.
