摘要
根据交通流量的实时大小建立交叉路口实时配时的数学模型,并用Webster绿信比算法对模型进行优化,使全体车辆在所有道口等待的时间最短.交通序列流采用泊松分布,用Matlab对模型进行实时仿真,优化后的结果较之前得到明显的改善.
Based on real-time traffic flow,a model of real-time traffic signal timing was created and also optimized by Webster split algorithm,which can lead to the shortest waiting time of all junctions.A real-time simulation was conducted by Matlab in the assumption of traffic flow obeying Poisson distribution.The simulation result of optimized model shows a significant improvement comparing with that of the previous model.
