According to multiphase traffic flow in a signal cross,a real-time dynamic model is established in this paper.With the queue length of the car as short as possible in cycle time for the target,green time of phase as control variable,realize the ad-justment of phase time based on improved genetic algorithm.The simulation result shows,compared with the common genetic algorithm and constant timing control.%根据单交叉路口多相位交通流建立了一种实时动态模型，以周期时间内车辆排队长度最短为优化目标，相位绿灯时间为控制变量，用改进的遗传算法实现对相位时间的动态调控。仿真结果表明，改进的遗传算法相对于普通遗传算法，能寻求到更优化的解，对于改善路口的交通拥挤状况，有着更为明显的效果。
