Application of Collaborative Optimization Strategies for Traffic Control of Urban Arterial Intersection

Abstract

Arterial roads are the aortic mainline connecting urban traffic. Because the traffic demand is huge, often leading to sectional traffic congestion, intersection bottlenecking is the main cause of traffic congestion. By collecting arterial intersection traffic flow data, we analyze the factors affecting intersection efficiency, and propose the sub-region classification method for arterial roads based on intersection factors. On the basis of the sub-region area defined, we propose the dissipated congestion strategy for road and arterial intersections to ease traffic congestion. Based on the multidimensional target of urban traffic management, we design multiple collaborative optimization plans for traffic control of the test road, and use the traffic simulation method to evaluate expected traffic control effect. As a result, we integrated the scientific traffic organization and traffic signal control method and applied them to solve the actual traffic problems, enhance the traffic control performance of urban arterial intersections, and provide a basis for carrying out traffic organization and signal control optimization around the country.
