Optimal design of transportation signal control at the intersection based on Webster signal timing method

Abstract

Urban transportation congestion has become a common phenomenon in the morning and evening peak. As the key node of urban transportation, optimizing the signal timing scheme of intersections is an effective measure to improve its traffic efficiency. In this paper, Webster signal timing method is used to optimize the signal timing scheme of intersection, and then VISSIM software is used to simulate the two schemes, and the queue length, parking times, travel time, delay time and pollution emission of each entrance at the intersection are optimized and analyzed. After optimization, the traffic condition of the intersection is obviously improved.
