随着经济的不断发展,人们对于物质的需求也越来越高,人们的出行越来越依靠小汽车,于是以以小汽车为主导的交通方式逐渐占领了城市的每一条道路。由此而引起了土地资源紧缺、环境污染严重、能源匮乏等问题,这些问题逐渐引起了人们的关注。于是,城市大运量公共交通应运而生。而有轨电车作为客运交通的代表,在城市交通的规划发展中也扮演着越来越重要的角色。
本文首先分析了有轨电车的运行特性,以及这种运行方式对于沿线交通所造成的影响。其次,对于有轨电车信号优先的关键技术进行了研究,简单介绍了信号控制系统的结构。另外,分析了不同的交叉口,有轨电车控制系统所采取的不同的控制策略。27498
同时,本文对有轨电车信号优先设计方法也进行了研究。有轨电车信号优先设计的几个步骤:车辆检测器的设置、有轨电车到达时间的预测、有轨电车优先级的选择、有轨电车信号优先控制策略的选择等几个方面在本文中都有详细的论述。此外,本文还对有轨电车对于沿线交通和冲突方向交通的影响进行了分析。
最后,本文对南京河西有轨电车的相关情况进行了介绍,支出了其现状运行的一些不足,并对采取了信号优先后,社会车流减少的延误进行了计算。

Title The key design of modern tram signal priority
Abstract
With the development of economy, people are getting the material demand is high, people travel more and more rely on the car, and then to the car as the dominant mode of transportation gradually occupied every road of the city. So, city public transit emerge as the times require. While the tram as representative of passenger transport, in the development of city traffic planning also plays a more and more important role.
At the same time, this article on the tram signal priority design method is also studied. There are several steps tram signal priority design: vehicle detector set, prediction, time of arrival of the tram tram priority selection, tram signal priority control strategy choice and so on several aspects are detailed discussed in this paper. In addition, this paper also on the trams were analyzed for effects of traffic along the route and direction of traffic conflict.
Finally, this paper has related situation tram was introduced to Nanjing Hexi, spending some deficiencies of the present state, and the adopted signal priority, reducing social traffic delays were calculated.
