The invention provides a traffic light duration calculation method, which is used for solving the technical problem that the accuracy of an automatic driving technology is influenced because the traffic light duration cannot be accurately calculated in real time in the prior art, and comprises the following steps: acquiring historical vehicle data of an intersection corresponding to a to-be-calculated traffic light; according to the historical vehicle data, vehicle data of at least one target vehicle is determined, and the target vehicle is a vehicle whose distance to the intersection is smaller than a distance threshold in a traffic light period; determining a stop moment and a start moment of each target vehicle at the intersection based on the vehicle data of the at least one target vehicle; and determining the red light duration of the traffic light according to the stop time and the start time of each target vehicle at the intersection.

    本发明提供一种交通灯时长的计算方法,用以解决现有技术中无法准确、实时的计算交通灯时长,影响自动驾驶技术精度的技术问题,该方法包括:获取待计算的交通灯所对应路口的历史车辆数据;根据所述历史车辆数据,确定至少一个目标车辆的车辆数据,其中,所述目标车辆为在一个交通灯周期内与所述路口的距离小于距离阈值的车辆;基于所述至少一个目标车辆的车辆数据,确定每个所述目标车辆在所述路口的停止时刻和启动时刻;根据所述每个目标车辆在所述路口的停止时刻和启动时刻确定所述交通灯的红灯时长。
