1北京理工大学珠海学院 2016 届本科生毕业论文过饱和流量下交叉口服务水平提升方法研究与实践摘要随着国家的发展、人民生活水平的提高与人均可支配收入的增加，汽车已经走入了家家户户，一个家庭有几辆小汽车已经是常事。由于家用小汽车的增加，道路上的汽车也越来越多，道路资源增长跟不上汽车数量的增长，所以道路压力也就越来越大。行车问题很大一部分发生在信号控制交叉口，而过饱和流量的交叉口往往问题更多，所以过饱和流量交叉口的优化是道路优化的一个重要组成部分。本文拟通过对过饱和流量下交叉口服务水平的提升来对目前的交通状况进行改善。本文选取的交叉口经过验证后得出的确是过饱和流量的交叉口，接着通过信号配时优化设计与干线协调控制对交叉口进行服务水平的优化提升，并最终利用 vissim 仿真模拟得出优化方案的可行与否。在最后还提出了一些本文未经验证的服务水平提升方案与建议给广大读者参考，如果有兴趣的读者可以自行研究并验证是否可行。关键词：交叉口;服务水平;信号控制;干线协调;vissim 模拟仿真。2北京理工大学珠海学院 2016 届本科生毕业论文AbstractWith the development of the country, the improvement of people's living standard and increase in disposable income per capita, cars have entered every family, it is common for a family to have several cars. So there are more and more motor vehicles in big cities in our country, but the growth of road resources and parking resources lags behind seriously, inevitably leads to the driving difficult, the vehicle difficult, the parking difficult contradiction is increasingly prominent. A large part of the traffic problem occurs at signal-controlled intersections, the intersection with supersaturated flow is often more problematic, so the optimization of supersaturated flow intersection is an important part of road optimization. This paper intends to improve the current traffic situation by improving the service level at the intersection under the condition of supersaturated flow. The intersection selected in this paper is proved...
