KNOWLEDGE-BASED SYSTEM FOR DESIGN OF SIGNALIZED INTERSECTIONS
A knowledge-based expert system (KBES) technology was used to develop a system for phasing and signal timing (PHAST) of an isolated intersection. Past expert systems addressing this problem focused on proof of applicability of the KBES concept to design problems and did not concentrate on knowledge acquisition. This study focused on acquisition and representation of the knowledge needed to solve this problem more completely. The system operates by selecting the phase plan and timing characteristics as a function of the demand on the intersection. The personal knowledge and experience of the authors were used in developing the rules for phasing and timing. Additional knowledge from the HCM (Highway Capacity Manual) was used in developing the rules for the timing of the intersection.
