The Simulation of Traffic Flow to Obtain Volume Warrants For Intersection Control

Abstract

THE PAPER REPORTS THE RESULTS OF A RESEARCH PROJECT IN WHICH A DIGITAL SIMULATION MODEL WAS DEVELOPED TO DETERMINE VOLUME WARRANTS AT STREET INTERSECTIONS. THE PARTICULAR TYPE OF INTERSECTION STUDIED WAS THE FOUR-LEGGED, RIGHT-ANGLED INTERSECTION OF A HIGH-VOLUME MAJOR ARTERIAL STREET WITH A LOWER-VOLUME MINOR ARTERIAL STREET. THE MAJOR ARTERIAL HAD FOUR TRAVEL LANES WITH PARKING PROHIBITED, WHEREAS THE MINOR ARTERIAL HAD TWO TRAVEL LANES WITH PARKING PERMITTED ON BOTH SIDES. BOTH ARTERIALS WERE OPERATED AS TWO-WAY STREETS. TWO TYPES OF INTERSECTION CONTROL WERE STUDIED, THE SEMI- TRAFFIC-ACTUATED SIGNAL AND THE TWO-WAY STOP SIGN. THE DELAYS ENCOUNTERED AT THE INTERSECTION WERE MEASURED AND USED AS CRITERIA FOR THE ESTABLISHMENT OF WARRANTS. /AUTHOR/
