Abstract
According to the traffic problems such as traffic congestion and buses moving slowly, the paper based on the idea of bus priority to introduced the per capita minimum delay of signal control method. In this paper, the intersection of Huaguang Road and Liuquan Road in Zibo Zhangdian was used as an example to propose a bus signal timing plan. By considering the impact of traffic delays and designing the phase of the intersection. It can reduce the per capita delay and improve service levels. Using Trans Modeler to simulate the timing scheme, the results showed that the optimized scheme can effectively reduce the per capita delay and ensure priority access for buses.
Highlights
Along with the rapid development of urbanization, the structure of road network is more and more complex
The traditional intersection timing method takes the minimum of vehicle delay as the target to determine the signal period length of the intersection, and the green time ratio of the intersection is divided according to the phase traffic flow ratio

Summary
Along with the rapid development of urbanization, the structure of road network is more and more complex. Considering the large number of buses carrying passengers, the green time ratio of each phase of intersections is reasonably allocated according to the proportions of traffic volume, and priority is given to bus passing. This method is used to ensure the distribution of the phase flow of the large proportion of the bus to the larger green time ratio. This signal timing method can ensure bus priority, reduce vehicle delays at intersections and improve the operational efficiency of road traffic. By constructing the Trans Modeler micro simulation platform to simulate the operation of vehicles, comparing the traffic delays before and after signal timing optimization at intersections, providing the virtual environment and technical support for verifying the feasibility of the scheme, and providing decision-making basis for traffic managers [4,5]
