The embodiment of the invention discloses a method and device for outputting a vehicle flow direction, roadside equipment and a cloud control platform, and relates to the technical field of artificial intelligence such as intelligent transportation and automatic driving. The method for outputting the vehicle flow direction comprises the steps of obtaining a driving track of a vehicle; obtaining a flow direction curve set corresponding to the road, wherein the flow direction curve set comprises at least one flow direction curve representing the flow direction of the vehicle; determining the similarity between each flow direction curve in the flow direction curve set and the driving track; and selecting the flow direction curve having the highest similarity with the driving track from the flow direction curve set as the flow direction of the driving track and outputting the flow direction. Therefore, errors caused by manual statistics of the traffic flow can be solved.

    本申请实施例公开了输出车辆流向的方法、装置、路侧设备以及云控平台,涉及智能交通、自动驾驶等人工智能技术领域。该输出车辆流向的方法包括:获取车辆的行驶轨迹;获取对应于道路的流向曲线集合,其中,流向曲线集合包含至少一个表征车辆流向的流向曲线;确定流向曲线集合中的各个流向曲线与行驶轨迹的相似度;从流向曲线集合中选择与行驶轨迹具有最高相似度的流向曲线作为行驶轨迹的流向并输出,从而可以解决以手工方式统计车流量导致的错误。
