The invention provides a traffic light countdown prompting method, device and equipment based on track mining, and relates to the technical field of traffic and the technical field of vehicles. The method comprises the steps that a server obtains a first track set and a traffic light period, then determines the time delay of the first track according to the first track, determines the traffic light duration according to the first track, the time delay of the first track and the traffic light period, and then sends the traffic light duration and the traffic light period to a terminal device. Afterwards, the terminal device determines traffic light countdown information according to the traffic light duration and the traffic light period, and then triggers the terminal device to carry out countdown prompt. According to the method provided by the invention, the time delay is added into the traffic light countdown prediction, so that a traffic light countdown prompt can be sent to the vehicle more accurately and effectively. According to the invention, the traffic light countdown is determined based on the track mining mode, so that the coverage rate of the intersection for sending the traffic light countdown prompt to the vehicle can be improved.

    本申请提供一种基于轨迹挖掘的交通灯倒计时提示方法、装置和设备,涉及交通技术领域和车辆技术领域。该方法包括:服务器获取第一轨迹集合,并获取交通灯周期,之后根据第一轨迹,确定第一轨迹的时延,再根据第一轨迹、第一轨迹的时延以及交通灯周期,确定交通灯持续时长,进而将交通灯持续时长和交通灯周期,发送给终端设备。之后,终端设备根据交通灯持续时长和交通灯周期,确定交通灯倒计时信息,再触发终端设备进行倒计时提示。本申请的方法,通过将时延加入到交通灯倒计时的预测中,可以实现更准确有效的向车辆发出交通灯倒计时的提示。本申请通过基于轨迹挖掘的方式确定交通灯倒计时,从而可以提高向车辆发出交通灯倒计时提示的路口覆盖率。
