IMPROVED OPERATION OF URBAN TRANSPORTATION SYSTEMS, VOLUME 3: THE DEVELOPMENT AND EVALUATION OF A REAL-TIME COMPUTERIZED TRAFFIC CONTROL STRATEGY

A real-time optimization program (RTOP) for traffic computer systems was developed, and the effectiveness of the mathematical algorithm was evaluated by means of an on-street implementation test. The program was designed to predict vehicular patterns based upon a combination of real-time traffic data from remote sensors and historical data. The program was also designed to optimize (based upon the predicted design patterns) signal timing parameters in a real world environment. The study demonstrated the potential and usefulness of the RTOP package. Its application in traffic signal control could produce significant improvement in traffic flow conditions over fixed-time control, provided it is used correclty and selectively. The reasons for favoring the RTOP package are discussed. The field tests indicated that the Central Areas performance of the RTOP surpassed that of the existing signal plans, whereas in the Suburban Area, the settings were much less effective. Characteristics of the suburban area which exaggerated the weaknesses of this version of the RTOP package are discussed.
