摘　　要：城市汽车保有量的增加使得十字路口采用固定时间进行控制交通信号灯的方式不能达到良好的疏导效果,基于不同方向车流量提出交通信号灯智能控制算法。根据车流量的大小动态调整不同方向绿灯的分配时间,确保车流量越大,该方向绿灯通行时间分配越长,实现十字路口交通疏散的目的。将提出的控制算法应用于仿真试验中,结果表明该算法能够动态调整不同方向绿灯分配时间,实现了对交通信号灯的智能控制,对缓解城市道路的交通拥堵具有一定的实际指导价值。The increase of urban car ownership makes it impossible to achieve a good evacuation traffic effect by using the time fixed control method to control the traffic lights at intersections.This paper proposes an intelligent control algorithm of traffic lights based on the traffic flow in different directions.The algorithm dynamically adjusts the allocation time of green lights in different directions according to the size of traffic flow to ensure that the larger the traffic flow is,the longer the allocation time of green lights in this direction is,so as to achieve the purpose of traffic evacuation at intersections.The proposed control algorithm is applied to the simulation test.The results show that the algorithm can dynamically adjust the allocation time of green lights in different directions and realize the intelligent control of traffic lights.This has certain practical guiding value for alleviating traffic congestion at urban intersections.
