The invention provides a traffic light control method and system, and the method comprises the steps: obtaining the real-time congestion road condition of an intersection through the shooting of a fixed camera device arranged at the intersection, introducing an image recognition technology to process the obtained real-time road condition image, obtaining the real-time vehicle queuing condition, and achieving the linkage of traffic lights, so that the more the vehicle queuing number is, the more serious the congestion is, and the green light passing time is increased through regulation and control, and the congestion condition is improved; and the traffic light waiting time of pedestrians at the intersection and the priority passing time of special vehicles are considered, so that the method is more humanized. 本发明提供了一种红绿灯控制方法及系统，通过路口设置的固定摄像设备拍摄获取路口实时拥堵路况，引进图像识别技术处理获取的实时路况图像，来获取实时车辆排队情况，联动红绿灯，车辆排队数量越多，拥堵更严重，则进行调控增大绿灯通行时间，改善拥堵情况；还考虑了路口行人的红绿灯等候时间、特殊车辆的优先通行时间，更加人性化。
