This project is an expert system to enable operations center personnel to better assist on-site responders to multiple incidents in an urban corridor of freeways and arterial streets. The GIS-based "expert system" provides an information database and prompts control center personnel, reminding them of important details such as the notification and coordination of various agencies or specific actions that must be taken. It also estimates incident clearance times which enable operations center personnel to estimate when traffic return to non-incident flows.

The expert system was developed through a Work Order with the Virginia Department of Transportation which contracted with the Virginia Polytechnic Institute and State University. It was demonstrated at the TRB Annual Meeting in January 1996. Work began in fall 1993 and it was completed in the fall of 1996. In July of 1997, the software was tested against actual incident data from the Virginia Department of Transportation's Northern Virginia Traffic Management Center in Arlington, and it was found to be close. Implementation of the system is being explored with the Virginia Department of Transportation in the Suffolk and Arlington areas.
