SIGOP/TRANSYT EVALUATION: SAN JOSE, CALIFORNIA

A COMPARATIVE STUDY OF THE EFFECTIVENESS OF THE SIGOP AND TRANSYT COMPUTER PROGRAMS WAS PERFORMED FOR OPTIMIZATION OF PRETIMED SIGNAL SETTINGS IN THE SAN JOSE, CALIFORNIA CENTRAL DISTRICT STREET NETWORK. SIGOP AND TRANSYT TIMING PLANS WITH 45-SECOND CYCLE TIMES WERE IMPLEMENTED IN SAN JOSE, AND FIELD EVALUATION DATA WERE COLLECTED DURING MORNING, NOON, AND AFTERNOON PEAK PERIODS. THE RESULTS INDICATED NO CONSISTENT, SIGNIFICANT DIFFERENCES BETWEEN SIGOP AND TRANSYT OPERATION AS MEASURED BY THE TOTAL NETWORK TRAVEL TIME. THE ONLY NOTABLE DIFFERENCE WAS DURING THE MORNING PEAK PERIOD, WHERE TRANSYT SETTINGS RESULTED IN APPROXIMATELY TEN PERCENT FEWER SIGNAL STOPS. /FHWA/
