摘　　要：针对现有的交通信号灯按时间控制系统面临着一些挑战,提出了一种基于雾计算的安全智能交通信号灯控制算法。通过车载网、路边接入网设备可以检测各方向车流量,通过控制平台协调车辆与交通灯之间的通信,综合运用基于哈希函数的雾计算,使交通灯获得高效的基于位置、速度和方向的车流量信息来最小化车辆的等待时间,提高交通效率,并通过Matlab仿真验证了其结果的正确性。In view of some challenges faced by the existing time-based traffic signal control system,a new intelligent traffic signal control algorithm based on the fog calculation is proposed.The vehicle flow can be detected through the vehicular network and roadside access network device,and the communication between vehicles and traffic lights is coordinated thorough the control platform.By using the Hash function-based fog calculation,the traffic lights can obtain high-efficient traffic flow information based on the position,speed and direction,which can minimize the vehicles’waiting time and improve the traffic efficiency.The correctness of the result is verified by Matlab simulation.
