The invention discloses an urban road traffic attribute acceleration calculation method, system and device and a medium. The method comprises the following steps: acquiring road network data of urban roads and GPS data of vehicles observable in the urban roads; according to the road network data of the urban road and the GPS data of each observable vehicle, performing vehicle traffic capacity complementation on any type of vehicles lacking driving data in unit time in the urban road; according to the traffic capacity of any kind of complemented vehicles, road network data of urban roads and observable GPS data of each vehicle, merging a common calculation process based on a MapReduce architecture, and carrying out parallel calculation to obtain road traffic attributes; therefore, the method can enable the calculation of the road traffic attributes to be quicker and more accurate.

    本发明公开了一种城市道路通行属性加速计算方法、系统、设备及介质,其方法包括以下步骤:获取城市道路的路网数据,及城市道路中可观察到的各车辆GPS数据;根据城市道路的路网数据及可观察到的各车辆GPS数据,对城市道路中单位时间内缺失行驶数据的任一类车辆进行车辆通行能力补全;根据补全后的任一类车辆通行能力、城市道路的路网数据及可观察到的各车辆GPS数据,基于MapReduce架构合并共有计算过程、并行计算得到道路通行属性;因此本发明可使道路通行属性的计算更为快速与准确。
