SIGNALIZING TRAFFIC NETWORKS: A SIMPLIFIED APPROACH

A COMPUTER MODEL WAS DEVELOPED WHICH EVALUATED A SEMI- TRAFFIC ACTUATED SIGNAL SYSTEM. THE HYPERLANG DISTRIBUTION WITH K = 2 WAS USED TO DESCRIBE VEHICLE ARRIVALS AT INTERSECTIONS. A COMPUTER PROGRAM WAS DEVELOPED WHICH TAKES FLOW RATES AT INPUT NODES TO THE SYSTEM AND USES THEM TO DETERMINE SIGNAL CYCLES AND PHASE SPLITS, TAKING INTO ACCOUNT SERVICE LEVEL AND VEHICLE DELAY. IN ADDITION, SPECIAL ATTENTION WAS PAID TO MINIMIZING BOTH THE AMOUNT OF DATA AND COMPUTER TIME REQUIRED IN AN EFFORT TO MINIMIZE THE SYSTEM COSTS. THE PROPOSED SYSTEM REDUCED THE TOTAL SYSTEM DELAY FROM 11.6 VEH-HR/HR TO 7.7 VEH-HR/HR. /TSR & A/
