摘要
根据交叉路口的实际情况,以等待放行车辆数为目标性能指标建立起四相位的单个交叉路口的信号实时优化配时模型及车流预测模型,运用遗传算法对其进行优化、仿真。仿真的结果显示:利用遗传算法进行交通信号配时优化,比传统优化方法更符合实际,可以较为合理地配置交叉口的相位时间,使得交叉路口的车辆延误时间尽可能的短,为实现交通流畅提供重要合理的信号配时方法。
A real-time model of four-phase traffic signal control according to the objective function of vehicle queue length in an intersection are presented.The object of the model are respectively single intersection.In this paper,the principle of the traffic signal control based on intelligent optimization,the genetic algorithm optimal theories is presented.The simulation tests of phase green duration in the mode are conducted using genetic algorithm method.The simulation results show that the optimal method of genetic algorithm is superior to tradition methods,and it is suitable for determining the green split in a single or more intersection.
