A Traffic Capacity Improvement Example of Urban Road Intersection

Abstract

The study of road intersection improvements is important, for intersections are one of the bottlenecks of urban traffic. Wengang Road - Jianjun Road crossing is an important intersection in Yancheng. Jianjun Road is an east-west main road, and there is a large number of motor vehicle traffic on it. Wengang Road is a north-south trunk road, where many large-scale freight trucks go through the road. Therefore, there is heavy and frequent traffic at this road intersection and traffic congestion is brought on. To address the traffic problem at this intersection, the authors apply single signalized intersection traffic signal control theory as the basis. They use urban roads organization and a road intersection signal timing method to study the improvements at this intersection. Two projects with improvements are achieved, and with analysis and evaluation, the authors choose the better one at the end.
