The invention provides a traffic flow speed calculation method and system, and relates to the technical field of traffic flow detection. The method comprises the following steps: firstly, acquiring the speed of a vehicle and the length of a target area, and acquiring the number of target vehicles passing through the target area within a preset time, the driving distance of each target vehicle in the target area and the staying time of each target vehicle in the target area; and calculating the traffic flow speed of the target lane according to the speed of the vehicle, the length of the target area, the number of the target vehicles passing through the target area within the preset time, the driving distance of each target vehicle in the target area and the staying time of each target vehicle in the target area. According to the technical scheme, the vehicle flow speed in the target lane can be more accurately obtained according to the vehicle running in the target area within the preset time instead of the vehicle speed at a certain moment and according to a plurality of vehicles in the target area instead of the side front vehicle.
本发明提供了一种车流速度的计算方法及计算系统,涉及车流量检测技术领域。本发明先获取自车的速度和目标区域的长度,并获取预设时间内从目标区域经过的目标车辆的数量、每个目标车辆在目标区域内行驶的距离以及每个目标车辆在目标区域停留的时间,然后根据自车的速度、目标区域的长度、预设时间内从目标区域经过的目标车辆的数量、每个目标车辆在目标区域内行驶的距离以及每个目标车辆在目标区域停留的时间计算得出目标车道的车流速度。上述技术方案依据的是预设时间内在目标区域内行驶过的车辆,而不是某一时刻的车速,并且依据的是目标区域内的多辆车,而不仅仅是侧前车,从而可以得到更准确地目标车道内的车流速度。
