This paper discusses the development of a prototype, multi-user, networked, real-time knowledge-based expert system (KBES) to provide decision support to California Department of Transportation (Caltrans) and California Highway Patrol (CHP) Traffic Operations Center (TOC) operators to more effectively accomplish their traffic management functions. The prototype system is to be field-tested in the new Caltrans District 12 TOC in Orange County early in 1993. This paper describes the development of incident detection, verification and response knowledge bases for the system, and their implementation using G2 real-time KBES development software on a Sun SPARCstation.
