The embodiment of the invention discloses a road congestion prediction method, equipment and a medium. Obtaining traffic flow historical information corresponding to the to-be-detected road; dividing the traffic flow historical information based on a time sequence to obtain traffic flow historical information corresponding to a plurality of time periods; based on the traffic flow historical information corresponding to each time period, determining a historical road congestion condition corresponding to the to-be-detected road; obtaining Gini coefficients respectively corresponding to the plurality of preset traffic flow division characteristics based on the plurality of preset traffic flow division characteristics and the historical road congestion data respectively corresponding to different times; and generating a decision tree based on the Gini coefficient, and determining the congestion condition of the to-be-detected road through the decision tree. Through the method, vehicle drainage can be carried out on the congested road section in time.
本申请实施例公开了一种道路拥堵预测方法、设备及介质。获取待检测道路对应的车流量历史信息;基于时间先后顺序将车流量历史信息进行划分,以得到多个时间段分别对应的车流量历史信息;基于每个时间段分别对应的车流量历史信息,确定出待检测道路对应的历史道路拥堵状况;基于多个预置车流量划分特征与不同时间分别对应的历史道路拥堵数据,得到多个预置车流量划分特征分别对应的基尼系数;基于基尼系数生成决策树,以通过决策树确定出待检测道路的拥堵状况。通过上述方法能够及时对拥堵路段进行车辆引流。
