摘要:
信号交叉口延误与车辆到达情况息息相关，研究红灯期间第一辆车辆到达的影响因素有助于更好的分析信号交叉口延误，从而更好的进行交叉口信号控制设计，提高交叉口的服务水平。本文首先通过拍摄视频提取红灯期间第一辆车到达停车线的停车时间与红灯启亮时间的差值，分析第一辆车到达特征。然后以信号交叉口进口道一条直行车道作为研究对象，对信号交叉口车辆到达影响因素进行了较细致的研究。选择了6因素5水平的影响因素进行分析，使用正交试验构筑了试验组合，并使用VISSIM软件对各种试验进行了仿真分析，得出了信号交叉口影响红灯期间第一辆车辆到达的因素程度依次为饱和度、车辆到达类型、交叉口间距、绿信比、饱和流量、大车率。最后考虑到饱和流量和饱和度存在交互影响，对饱和流量和饱和度使用交互分析，得到结果：在饱和流量为1650pcu/绿灯小时，且饱和度为0.25时，对车辆到达的影响程度最高。
Abstract:
Signalized intersection delay is closely related to vehicles. Research on the first vehicle arrival during red light is contribute to better analysis of influence factors of delay at signalized intersections, thus contribute to better intersection signal control design to improve the level of service. Firstly, The paper analyzes feature of the first vehicle arrival base on time difference between stopping time of the first car arriving at the stop line during the red light and the start of Red time,. And then the paper studier intersection of a straight line approach and puts more detailed studies on the factors affecting the vehicle arrives at signalized intersection. The 6 factors and 5 levels are chosen considering the possible impacting factors. The orthogonal experiment is used to get the experiments’ combination, and the VISSIM software is used to get the experiment scene. Based on the simulation model, the order of the factors impacting the first vehicle arrival during red light is the saturation, types of vehicles arrival, intersection spacing, the split, the saturated flow, the bus ratio. Finally For the interaction phenomenon of saturated flow and saturation, using transactional analysis to learn that: when saturated flow is 1650pcu/the green light for hours, and saturation is 0.25, there is the highest level of impact on the vehicles.
