One or more embodiments of the invention provide a traffic flow prediction method and apparatus, a computing device and a medium. The method comprises the steps that the topological relation of all point locations in a set road section is obtained according to road network data, and the point locations are arranged on the set road section at set intervals; according to the traffic flow speed and traffic flow of the set road section in the set time period, determining a first point location having an association relationship with a predicted point location in the point locations based on the topological relationship; and according to the flow information of the predicted point location and the first point location in the set time period, predicting the flow information of the predicted point location in a target time period after the set time period. According to the method, the influence relationship between each point location and the predicted point location can be determined more accurately based on the speed information and the flow information of the point locations, and the flow information of the target time period can be predicted more accurately based on the first point location having the association relationship with the predicted point location.

    本公开一个或多个实施例提供一种交通流量预测方法、装置、计算设备及介质。所述方法包括:根据路网数据获取设定路段中各个点位的拓扑关系,其中,所述点位是以设定间隔在所述设定路段上设置的;根据所述设定路段在设定时间段的交通流速度和交通流量,基于所述拓扑关系确定所述各个点位中与预测点位具有关联关系的第一点位;根据所述预测点位以及所述第一点位在所述设定时间段的流量信息,预测得到所述预测点位在所述设定时间段之后的目标时间段内的流量信息。基于点位的速度信息和流量信息确定,可以更准确地确定各个点位与预测点位的影响关系,基于与预测点位具有关联关系的第一点位,可以对目标时间段的流量信息进行更准确的预测。
