VISSIM在交叉口優(yōu)化仿真中應(yīng)用研究
[Abstract]:With the rapid development of China's economy, the number of motor vehicles has increased rapidly, and the traffic demand has generally increased. The traffic problems brought along with it have brought about the waste of energy, the reduction of urban efficiency, and the serious noise pollution and air pollution. With the improvement of urban construction in China, it is of great significance for the long-term development of Chinese cities to pay attention to the study of traffic problems, to do well traffic planning, to avoid repeated construction and to construct a reasonable urban layout. This paper studies the operation of intersection in microscopic traffic simulation field. Intersection in the traffic network in the hub position, traffic problems, if the operation is not smooth, it is easy to cause traffic congestion and reduce traffic efficiency. Therefore, it is of great practical significance to improve the traffic capacity of intersections through channelization and signal timing optimization. This paper introduces the main research stages, research contents, achievements and the main software of traffic simulation in recent years, both at home and abroad. In this paper, the micro simulation software VISSIM is used to simulate and simulate the intersection, and two methods of optimizing the intersection are introduced, which are channelization and signal timing optimization. In the part of signal timing optimization, the optimal timing software Synchro is selected to optimize the timing, and a better scheme is designed, and then the optimized scheme is brought into the VISSIM model for verification to ensure the effectiveness of the optimization measures. Finally, empirical research is carried out, and the typical intersection of Dawangqiao in Beijing is selected to simulate and simulate, and the optimization measures are put forward. Through this simulation, the traffic network in Beijing can run more effectively, which reflects the research value and significance of traffic simulation.
