A Demonstration of Expert Systems Applications in Transportation Engineering
Faghri, Ardeshir.
Year: 1988
VTRC No.: 89-R3
Abstract: The development of a prototype knowledge-based expert system (KBES) for selecting appropriate traffic control strategies and management techniques around highway work zones was initiated. This process was encompassed by the steps that formulate the problem as an expert system: identification, conceptualization, implementation, and testing. The resulting EXSYS prototype system, TRANZ, is described in the report and demonstrated on the system disk. An alternative approach using the LISP programming environment was produced using a part of the TRANZ knowledge base for comparative purposes. This EXSYS prototype system is interpreted as the initial stage in the development of an expert system. Additional work that includes testing, validation, and verification is necessary before the system can be recommended to practitioners for professional applications.
