【摘要】：随着城市的迅速发展，交通拥堵现象越来越严重。可变车道控制在信号交叉口处的实施能够有效缓解交通拥堵瓶颈问题。信号交叉口进口道实施可变车道能够在现有的道路资源条件下有效的提高交叉口的通行能力。因此，本文基于信号交叉口进口道处可变车道属性过渡时主预信号协调控制的问题进行了研究。本文在城市道路交叉口配时理论、通行能力理论和延误理论的基础上，，探讨和研究了交叉口进口道处可变车道主预信号协调控制方法。文章首先介绍了信号交叉口可变车道和预信号的概念以及可变车道实施的条件和检测器布设的要求、信号交叉口进口道可变车道控制的类型；然后根据交叉口信号配时和通行能力的基本理论分析探讨了不同交通量条件下信号交叉口进口道可变车道属性改变前后通行能力的变化从而得出了可变车道属性改变的控制条件；之后分不同的情况对信号交叉口进口道处可变车道属性过渡时主预信号之间协调控制关系进行了理论推导和分析，得出了在不同的情形下主预信号之间协调控制关系模型；最后通过Vissim仿真的方法对信号交叉口进口道实施可变车道控制前后车辆运行状态和延误进行了对比分析，证明了可变车道的实施能够有效地降低信号交叉口进口道处车辆的延误，减小车辆的排队长度。从而为交通控制者提供了理论依据和支撑。
[Abstract]:With the rapid development of the city, Traffic congestion is becoming more and more serious. The implementation of variable lane control at signalized intersections can effectively alleviate the bottleneck problem of traffic congestion. The implementation of variable lanes at signalized intersections can be carried out under the conditions of existing road resources. Effectively improve the capacity of intersections. In this paper, the coordination control of the main presignal during the transition of variable lane attribute at the entrance of signalized intersection is studied. This paper is based on the theory of timing, capacity and delay of urban road intersection. This paper discusses and studies the coordinated control method of main pre-signal of variable lane at the entrance of intersection. Firstly, the concept of variable lane and pre-signal of signalized intersection, the conditions of implementation of variable lane and the requirements of setting up detector are introduced in this paper. The type of variable lane control at signalized intersections; Then, according to the basic theory of signal timing and traffic capacity at intersection, the change of traffic capacity before and after the change of variable lane attribute at signalized intersection entrance under different traffic volume is discussed, and the variable lane attribute is obtained. Changing control conditions; Then the coordination control relationship between the main presignals during the transition of the variable lane attribute at the entrance of the signalized intersection is deduced and analyzed theoretically, and the model of the coordinated control relationship between the main presignals under different circumstances is obtained. Finally, the vehicle running state and delay before and after variable lane control at signalized intersections are compared and analyzed by Vissim simulation method. It is proved that the implementation of the variable lane can effectively reduce the vehicle delay and the queue length at the entrance of signalized intersection, thus providing a theoretical basis and support for traffic controllers.
