Abstract
With the accelerated pace of people's lives and works, traffic congestion, traffic accidents and traffic emissions have become one of the most important topics in the major cities of China in the last few years. The arterial coordination control method is one of the important methods to reduce traffic pollution, improve traffic efficiency and relieve traffic pressure. This paper will take traffic signal tuning scheme design of Zhongshan Street of Yinchuan city as the goal to design a group-based arterial coordinated control scheme. In the course of the study, the traditional algebraic method of signal coordination control theory and the traffic simulation software Synchro (Simtraffic) are used to develop the traffic control strategy for Zhongshan street, After the simulation, the results of the two schemes are compared with stops and travel time.The results show that this paper provides a feasible solution to alleviate the traffic congestion, improve traffic efficiency, reduce traffic pollution and reduce traffic accidents of Zhongshan street.

Summary
A coordinated control scheme based on grouping and simulation is designed based on coordinated control of green wave in trunk lines, and a traffic signal tuning scheme is designed for Zhongshan street, Yinchuan city, Ningxia hui autonomous region. In the process of designing the coordinated control strategy of green wave in the main line, this paper focuses on the fact that the current signal timing scheme cannot meet the actual traffic demand. It carries out single-point optimization, and improves the signal timing based on the characteristics of the actual traffic flow, so as to achieve the matching between the designed lamp timing scheme and the actual traffic demand. The effect comparison was measured by the number of stops, the travel time at intersections and the average speed of the sections
