基于VISSIM仿真的交通组织优化研究

Study on traffic organization optimization based on VISSIM simulation

近年来,随着人民生活水平的提高,道路上的人流车流越来越多,所以各交叉口以及交叉口之间路段的交通流密度也在逐步增加,所以,如何发现所研究区域内的主要交通问题,并拟定出具有针对性的交通道路组织优化方案与措施,具有十分重要的意义。文章详细分析了影响城市平面交叉口车辆通行的因素,对交叉口的通行能力、饱和度、延误、排队长度等基本评价指标作出分析,最后选择焦作市某交叉口作为案例进行验证优化,提出三种优化方案,并运用VISSIM仿真软件对优化方案进行仿真评价。

In recent years, with the improvement of people’s living standard, people on the road of traffic is increasing, so the intersection between sections and intersections of traffic flow density are also gradually to increase, so, how to find the main traffic problems in the study area, and proposed a targeted traffic organization optimization scheme and measures, has the very vital significance. This paper analyzes the factors that influence the urban traffic plane intersection traffic capacity of intersection, saturation, delay, queue length, the basic evaluation indexes such as to make analysis, finally choose Jiaozuo city as a case to verify a certain intersection optimization, three optimization scheme is put forward, and using the VISSIM simulation software to optimize the simulation program evaluation.
