摘要：	Non-recurrent congestion from traffic accidents and other incidents is a major component of the overall metropolitan congestion. In view of pending deployment of new technologies, incident management programs designed to mitigate non-recurrent congestion must be linked to Intelligent Transportation Systems [ITS]. While the number of incident management [IM] programs is increasing, building a mandate and obtaining sufficient funding is often hampered by the inability to satisfactorily quantify the expected benefits from such programs. The direct link between such IM programs and the application of ITS technology is often unclear and improperly assessed. This research conducted for the Virginia Department of Transportation, employs a combination of expert opinion, field research and simulation modeling to estimate benefits of promising ITS applications to incident management. The incident impact analysis model [IMPACT] developed for the FWHA by the California Polytechnic State University, San Luis Obispo, was tested, adapted and applied in the context of incident management in Northern Virginia, the Virginia part of the U.S. National Capital region. Estimates were generated for several current and expected ITS-enhanced incident management scenarios, indicating that a 35% reduction in annual delays due to incidents and an associated monetary cost-savings are approximately $14.5 million per annum has already been achieved with the existing incident management program. Current delays may be reduced by an additional 21 to 46 percent through the deployment of ITS applications, with associated savings of $6 to $12.5 million annually. The approach presented here may be used by agencies to better describe and quantify benefits of current and future incident management scenarios, on a regional basis.
