北京理工大学珠海学院 2020 届本科生毕业论文基于 VISSIM 的交叉口借道左转信号配时方案研究基于 VISSIM 的交叉口借道左转信号配时方案研究摘 要交叉口中的左转车辆是引起车辆冲突和交叉口延误的主要因素,本文通过对相关交叉口进行实地调查,收集相关数据,再通过分析借道左转的原理,在适当的位置设置借道左转车道;在此基础上,以减少交叉口延误和提高通行效率为目标,运用交通信号控制的配时方法,并在周期限制、车道长度限制等条件下,对交叉口的信号配时进行优化,设置合理的预信号配时方案。通过 VISSIM 仿真表明,在交叉口适当的位置设置借道左转车道,并进行合理的信号配时优化,能够有效的减少交叉口左转车辆的延误,降低排队长度,本文结果表明为信号控制交叉口借道左转提供一定的理论支撑和指导。关键词:借道左转;延误;信号配时优化;预信号;VISSIM 仿真;北京理工大学珠海学院 2020 届本科生毕业论文Study on timing scheme of left-turn signal at intersection based on VISSIM AbstractThe left-turn vehicles at intersections are the main factors leading to vehicle conflicts and delays at intersections. This paper conducts a field survey of relevant intersections and analyzes their data. Through the analysis of the principle of turning left through the lane, set the lane in the appropriate position; On this basis, with the goal of reducing delays at intersections and improving traffic efficiency, the timing method of traffic signal control is applied to optimize signal timing at intersections under the conditions of cycle limits and lane length limits, and a reasonable pre-signal timing scheme is set up. VISSIM simulation shows that setting a left-turn lane at an appropriate location at an intersection and making a reasonable signal timing optimization can effectively reduce the delay of left-turn vehicles at the intersection and reduce the travel time and queue length. The results of this paper show that it provides certain theoretical support an...
