Development of a prototype real-time expert system for managing non-recurring freeway congestion.

Fundamental to the operation of most Intelligent Vehicle-Highway System (IVHS) projects are advanced systems for surveillance, control and management of integrated freeway and arterial networks. A major concern in the development of such Smart Roads, and the focus of this paper, is the provision of decision support for traffic management centre personnel, particularly for addressing non-recurring congestion in large or complex networks. In this paper, we present and discuss the development of FRED (Freeway Real-Time Expert System Demonstration), a component prototype real-time expert system for managing non-recurring congestion on urban freeways in Southern California.
