Abstract
In the process of urban construction, people pay more attention to the construction of broad roads, which leads to a large number of vehicles gathering on the road, cannot be evacuated in time and causes congestion. The purpose of building a high-density road network is to improve the structure of the road network and relieve traffic congestion. Therefore, the near intersections under the high-density road network are the key to relief traffic congestion. Firstly, after analyzing the characteristics of high-density road network, a small two-way regional road network is established, and the intersection spacing is 200m. Then propose accurate solutions to coordination problems and traffic signal coordination organization of the regional road network. Secondly, a variety of timing signal coordination methods are applied to the two-way road network, then the traffic organization form of the road network is changed, the total traffic input of the road network with different organization forms is controlled to be the same, and then the corresponding signal coordination optimization is carried out. Finally, the VISSIM simulation results are used to compare the coordination schemes, and the best coordination scheme in the small area road network is selected to improve the traffic operation efficiency.
