The invention discloses a traffic light change period determination method and a related device. Acquiring vehicle speeds of a plurality of vehicles at the target traffic light intersection and moments corresponding to the vehicle speeds; determining M groups of vehicle speeds from the vehicle speeds corresponding to the plurality of vehicles; for at least two vehicle speeds respectively included in the M groups of vehicle speeds, a plurality of vehicle speeds after arrangement are obtained according to the sequence of first moment difference values between the moment corresponding to each vehicle speed and the starting moment of the time period corresponding to the vehicle speed from small to large; determining a third vehicle speed from the plurality of vehicle speeds after arrangement; in a first period between the starting moment of the time period and a first moment difference value corresponding to the third vehicle speed, determining that the target traffic light is changed to be red; and in a second period between the first moment difference value corresponding to the third vehicle speed and the end moment of the time period, determining that the target traffic light is changed into green light. Therefore, the M groups of vehicle speeds are superposed in the same time period, and the traffic flow is simulated and increased, so that the change period of the target traffic light is accurately determined.
本申请公开了一种交通灯变化周期的确定方法及相关装置。获取多个车辆在目标交通灯路口的车速以及每个车速对应的时刻;从多个车辆分别对应的车速中确定出M组车速;针对M组车速分别包括的至少两个车速,按照每个车速对应时刻与该车速对应时间周期的起始时刻之间的第一时刻差值从小到大的顺序排列得到排列后的多个车速;从排列后的多个车速中确定出第三车速;在时间周期的起始时刻与第三车速对应第一时刻差值之间的第一周期,确定目标交通灯变化为红灯;在第三车速对应第一时刻差值与时间周期的结束时刻之间的第二周期,确定目标交通灯变化为绿灯。如此,将M组车速叠加至同一时间周期内,模拟增大车流量,进而准确确定出目标交通灯的变化周期。
