基于VISSIM和Matlab的信号灯控制策略研究

Control Strategy Analysis of Traffic Light Via VISSIM and Matlab

简要介绍了交通仿真软件VISSIM仿真系统的基本信息,并对所应用到的模块进行了简单的介绍。为了验证VISSIM仿真平台模拟真实道路交通状况的有效性,在VISSIM仿真系统中,搭建了相应的上海市莲花南路干线古龙路至古美路段5个交叉路口的仿真模型。仿真过程中应用Matlab软件分析相应路段的有关scats数据,以便确定仿真过程中所需设定的变量数值以及各个交叉路口的放行方式。在VISSIM仿真系统中,实现了对多个路口控制策略的仿真,并给出了延误时间和平均停车次数的仿真结果。

VISSIM is a frequently used simulation tool for the analysis of the traffic. Some conceptions and useful modules of VISSIM are briefly introduced in this paper. The objective of this paper is to validate the effectiveness of the simulation of real traffic status via VISSIM. The simulation model of the five intersections of South Lianhua trunk road is setup in VISSIM. Based on the Matlab and relevant scats data of real traffic status, the values of VISSIM variables and the traffic strategy of each intersection are then discussed. The control strategy of multi intersections is realized in VISSIM, and the simulation results of delay time and average stop times are also provided. The simulation results indicate that the new strategy is easier to accomplish and adjust in practical applications.
