【摘要】：随着社会经济和城市化的快速发展，城市交通拥堵问题日益严重，通过优先发展公共交通来解决城市交通拥堵问题已成为国内外交通工作者研究的重点。干线信号协调控制是城市交通控制中一种常见的控制方式，研究在不影响干线协调控制效果的基础上如何实现公交优先控制具有重要的现实意义。为了解决在干线协调控制系统中实现公交优先，本文结合TransModeler软件中的公交优先原理建立了实施公交优先的判断条件及优先级别判断规则，根据判断规则及条件建立了面向公交优先的干线信号协调控制框架，控制系统共分为两层，上层为普通干线信号协调控制层，下层为公交信号优先控制层，根据公交车辆所处相位，分别建立了协调相位公交优先控制算法和非协调相位公交优先控制算法。为了验证干线系统下公交优先算法的效益和可行性，以淄博市张店区柳泉路为例，选取柳泉路—中润大道、柳泉路—联通路、柳泉路—华光路、柳泉路—人民路、柳泉路—共青团路5个交叉口作为干线信号控制系统，在Transmodeler软件中建立仿真系统并添加公交优先信号控制，仿真有无公交信号优先下的干线协调控制，以路段和交叉口输出的仿真结果作为对比分析数据，，仿真结果表明，该控制算法能有效降低干线车均延误、交叉口人均延误和改善交叉口服务水平。
[Abstract]:With the rapid development of social economy and urbanization, urban traffic congestion is becoming more and more serious. To solve the problem of urban traffic congestion by giving priority to the development of public transport has become the focus of domestic and foreign traffic workers. Coordinated control of trunk signals is a common control method in urban traffic control. It has important practical significance to study how to realize bus priority control without affecting the effect of trunk line coordinated control. In order to solve the problem of realizing bus priority in the trunk line coordinated control system, combining with the principle of bus priority in TransModeler software, this paper establishes the judgment conditions and priority level judgment rules of bus priority. According to the judgment rules and conditions, a coordinated control framework for bus priority is established. The control system is divided into two layers, the upper layer is the general trunk line signal coordination control layer, the lower layer is the bus signal priority control layer. According to the phase of public transport vehicle, the coordinated phase bus priority control algorithm and the uncoordinated phase bus priority control algorithm are established, respectively, in order to verify the efficiency and feasibility of the bus priority algorithm under the trunk line system. Taking Liuquan Road, Zhangdian District, Zibo City as an example, five intersections of Liuquan Road, Zhongrun Avenue, Liuquan Road and Unicom Road, Liuquan Road and Huaguang Road, Liuquan Road and people's Road, Liuquan Road and Communist Youth League Road are selected as the main line signal control system. The simulation system is established in Transmodeler software and the bus priority signal control is added to simulate the trunk line coordination control with or without bus signal priority. The simulation results of road sections and intersections are compared and analyzed. The simulation results show that, The control algorithm can effectively reduce the average delay of trunk train, the average delay of intersection and improve the service level of intersection.
