The invention provides an intersection traffic light control method and device, and belongs to the technical field of traffic safety. The method comprises the following steps: acquiring an intersection vehicle driving image, and determining a vehicle lane changing intention of each driving vehicle in a preset path section of the intersection vehicle driving image based on the intersection vehicle driving image; and according to the vehicle lane changing intention and the traffic flow of the lane to be changed in the intersection vehicle driving image, determining the lane changing time of each vehicle to be changed corresponding to the vehicle lane changing intention. And according to each lane changing time and the corresponding lane to be changed, generating a data map of the intersection vehicle driving image. And based on the data map, determining whether the traffic volume of the current intersection is less than a preset threshold. And under the condition that the traffic volume of the vehicles at the current intersection is smaller than a preset threshold value, updating the traffic light operation cycle of the current intersection according to each lane changing time so as to control the traffic light system to operate according to the updated traffic light operation cycle.

    本申请提供了一种路口红绿灯控制方法及设备,其属于交通安全技术领域。该方法获取路口车辆行驶图像,基于路口车辆行驶图像,确定路口车辆行驶图像的预设路径段中各行驶车辆的车辆变道意图。根据车辆变道意图以及路口车辆行驶图像中待变道车道的车流量,确定车辆变道意图相应的各待变道车辆的变道时间。根据各变道时间及相应的待变道车道,生成路口车辆行驶图像的数据地图。基于数据地图,确定当前路口车辆的通行量是否小于预设阈值。在当前路口车辆的通行量小于预设阈值的情况下,根据各变道时间,更新当前路口的红绿灯运行周期,以根据更新后的红绿灯运行周期,控制红绿灯系统运行。
