中文摘要	为了使交通信号配时方案及时反映道路交通流量的变化,以达到最优的控制效果,设计并实现一种用于交通信号配时方案实时仿真系统。该系统基于ARM Cortex-A8处理器,集成在信号控制器内部,分布于各交叉路口。在设计应用软件时以单路口四相位交通流为例进行分析,并以平均延误时间为评价指标进行建模,运用遗传算法对当前交通流下各方案进行仿真,评估出最优配时方案。通过实际验证,该系统通过实时仿真能够给出交通控制信号最优方案,减少车辆的平均延误时间。; In order to reflect the change of traffic flow timely and achieve the optimal control effect,a real-time simulation system for traffic signal timing plan based on ARM Cortex-A8 is designed and realized.It is integrated in signal controller distributed in each intersection.In design of application software,analyze an intersection with four-phase traffic flow;and take average time delay as evaluation index for modeling and use genetic algorithms to simulate each scheme under current traffic flow,and evaluate optimal timing scheme.It is verified by practice that the system can give the optimal solution timely and decrease average time delay of vehicle.
