基于可变导向车道及信号配时优化的交叉口综合优化方案设计摘 要由于机动车数量的增加导致的交通拥堵，已经成了城市首要解决问题之一，特别是早晚高峰的时候。因此提高道路交叉口的通行效率对解决拥堵很有必要，车道功能规划与信号配时设计会直接影响交叉口的通行效率。其中有些交叉路口出现潮汐现象，早高峰和晚高峰时，左转车辆比直行车辆多，平峰的时候左转车辆较少，导致只有一条左转车道的路口出现各转向车辆不均衡，可变导向车道的诞生，对这类交叉口通行效率的提升有显著作用，它可以根据各转向的交流量需求对其车道功能进行调整，使得交叉口的道路资源得到最大化利用，伴随着车道功能的变化，该交叉口的通行效率有所提高。使用所选取某个信号交叉口的实测数据并利用 PTV VISSIM 进行仿真模拟，研究对某个下降交叉口左转流量较大的现状研究中，设置可变导向车道对信号交叉口的通行能力的影响以及通行效率等交通评价指标对比。以广州市某信号交叉口为例，提出针对左转车流量较大的现状优化方案。关键词：可变导向车道，交通拥堵，VISSIM 仿真北京理工大学珠海学院 2020 届本科生毕业设计Design of intersection comprehensive optimization scheme based on Variable Guide lane and signal timing optimizationAbstractTraffic congestion caused by the increase of the number of motor vehicles has become one of the most important problems in the city, especially in the morning and evening rush hours. Therefore, it is necessary to improve the traffic efficiency of the intersection to solve the congestion. The lane function planning and signal timing design will directly affect the traffic efficiency of the intersection. In some intersections, there are tides. In the early peak and late peak, there are more left turning vehicles than straight traffic, and there are fewer left turning vehicles in the flat peak. As a result, there are only one left turning lane at the intersection with unbalanced turning vehicles. The birth of variable guide Lane plays a significant role in improving the traffic efficiency of ...
