The invention relates to a method, a device and a system for determining the average speed of a road section, a computer readable storage medium and a computer device. The method comprises the following steps: acquiring vehicle positioning information obtained from a distributed message system within a target time interval; wherein each piece of vehicle positioning information comprises a vehicleposition point and a vehicle speed; based on a flow processing framework, respectively determining a road section to which each vehicle position point belongs from predetermined road sections; and based on the vehicle speed corresponding to the vehicle position point belonging to the predetermined road section, obtaining a section average speed of the predetermined road section in the target timeinterval. According to the scheme provided by the invention, the availability of the system can be improved.

    本申请涉及一种路段平均速度的确定方法、装置、系统、计算机可读存储介质和计算机设备。所述方法包括:获取目标时间间隔内从分布式消息系统得到的车辆定位信息;其中,各所述车辆定位信息包括车辆位置点和车辆速度;基于流处理框架,从预定道路路段中分别确定各所述车辆位置点所属的道路路段;基于属于所述预定道路路段的车辆位置点所对应的车辆速度,得到所述预定道路路段在所述目标时间间隔内的路段平均速度。本申请提供的方案能够提高系统的可用性。
