摘　　要：随着城市私家车的日益增多,交通拥堵等问题也越来越严重。交叉路口交通信号配时直接影响道路通行效率,而定时或多时段控制交通信号,无法及时根据车、人流量优化控制交通信号。以城市单交叉路口三车道为基础,来探讨基于NSGA II的智慧交通信号优化方案,以车辆延误、排序长度和行人延误三个目标优化交通信号配时方案。通过实验分析NSGA II和GA算法表明,NSGA II在多目标交通信号中配时更智慧,能取得更优交通效益。The increasing number of private cars in cities has led to urgent solutions to traffic congestion and other issues.The timing of traffic signals at intersections will directly affect road traffic efficiency and effectively alleviate traffic problems.Controlling traffic signals at fixed times or multiple time periods cannot optimize traffic signals based on vehicle and pedestrian flow in a timely manner.Based on the three-lane urban single intersection,this paper explores a smart traffic signal optimization scheme based on NSGA II,aiming to optimize the traffic signal timing scheme with three objectives:vehicle delay,sorting length and pedestrian delay.Through experimental analysis of NSGA II and GA algorithm,NSGA II is more intelligent in multi-objective traffic signal timing and achieves better traffic efficiency.
