[Abstract]:Intersection area is the most serious conflict and accident area in the whole urban traffic system. Therefore, combining modern computer technology, sensor technology and communication technology, it is of great significance to carry out intelligent control for intersection, improve the efficiency of traffic signal control and reduce the delay time in conflict area. In this paper, the signal control of urban intersection is studied, and the signal control of intersection is simulated by using the micro simulation software VISSIM developed by PTV Company of Germany. The simulation system is connected with the external hardware system through the application data interface VISSIM_COM, provided by the software. The traffic data information and the signal control system data are collected in real time. The simulation results are outputted and the signal control scheme is analyzed. The main work of this paper is as follows: 1. The basic model of traffic simulation, the basic mode of signal control and important parameters are introduced. The influence of parameters on the basic simulation process is studied and analyzed. 2. The whole design of the simulation system is carried out, and each function part is modularized, the scheme analysis and design are carried out respectively, and the communication rules between each part are briefly analyzed. 3. The microcosmic simulation software VISSIM is introduced in detail. The standard simulation engineering experiment is established at the intersection and section along Guang Road in Tianjin, and the simulation experiment of timing signal control is completed. Selected a specific section of the induction signal control simulation experiment; 4. Using the VISSIM_COM interface and external signal controller interface provided by VISSIM software, the secondary development and utilization of virtual simulation environment and real traffic data interface are realized, and the real-time adjustment and control of signal control scheme are completed.
