Subject review Emergency traffic management calls for integration of strategies covering advanced information collecting/disseminating fallibilities, and effective message broadcast system. Approximate "permanent" alternate routes combining intelligent transportation system measures could objectively play a vital role in supporting the category of specific congestion alleviation and incident management. This paper attempts to address a methodology of prioritizing such "permanent" alternate routes via major traffic generators/attractors for route guidance and traffic diversion strategies in the concerned local network. A scenario of emergency management and operation is demonstrated to discuss the collection of real-time traffic data, location and duration evaluation of incident, identification of alternative routes and congestion evocation integrated with ITS, using a mixed network near Xi’an Ming City Wall as a VISSIM example. Finally, types of diagrammatic route guiding signs are addressed with application samples.
