平面交叉路口交通信号控制策略研究

Research on Traffic Signal Control Strategy of Crossroads

在分析当前平面交叉口交通信号控制技术的基础上,重点研究交通信号控制配时策略,结合现代智能交通的需求,提出一种平面交叉路口的通用模型及描述各种实际路口的通用方法,根据路口的各车流向的期望车流量的实时预测结果实时生成最优配时的自适应算法。算法实时改变相位车流向组成,系统适应能力有较大的提高。

On the basis of analyzing current control techniques of traffic signal control of crossroads and the commands of modern ITS,the thesis puts emphasis on researching time assignment of traffic signal control and puts forward a gen-eral reference model for crossroad and a method to describe all kinds of crossroads,and then an optimized adaptive al-gorithm of automatic time assignment for crossroad traffic lights.The time assignment is timely generated according to re-al-time prediction of expected traffic volume.The adjustability of traffic control system enhance greatly for the algorithm can timely change the makeup of lanes which make up the phase.
