基于增广Petri网的实时交通信号控制系统
A Real-time Traffic Signal Control System Based on Extended Petri Net
【摘要】 利用带抑制弧/使能弧、自控网技术的增广Petri网设计了一种交叉路口实时交通信号控制系统,通过采集路面车流量信息实时改变每个信号灯周期内各相位时长,模型通过了正确性分析.并依据该模型开发了Java原型系统,实验表明该系统能有效缓解交叉口的交通滞留.
【Abstract】 Using the extended Petri net with the cyber net technology,the inhibitor arc and the enable arc,a real-time traffic signal control systems is built.By collecting road traffic flow,each phases of signal is changed on real-time.Analysis of the system model is correct.A Java prototype system is developed based on the model.The application shows that the system can reduce traffic stranded in intersection.
