The embodiment of the invention discloses a traffic road condition prediction method, and the method comprises the steps: determining a neighbor road section of a target road section from a target road network, so as to obtain the feature parameters of the target road section and the neighbor road section, and the historical traffic road condition information in a historical time period; generating target data features according to the feature parameters of the target road section and the neighbor road section of the target road section and the historical traffic road condition information in the historical time period, so as to predict the traffic road condition information of the target road section at the preset moment according to the target data features; the historical time period is the same preset time period in different dates before the preset moment, and the obtained historical traffic information comprises the historical traffic information of the neighbor road section having spatial correlation with the target road section, so that the historical traffic data has time correlation and spatial correlation; and the accuracy of predicting the traffic road condition information by using the traffic road condition prediction model can be improved.

    本说明书实施例公开了一种交通路况预测方法,通过从目标路网中确定出目标路段的邻居路段,以获取目标路段与邻居路段的特征参数和在历史时间段内的历史交通路况信息,然后根据目标路段和目标路段的邻居路段的特征参数和历史时间段内的历史交通路况信息去生成目标数据特征,从而便于根据目标数据特征预测目标路段在预设时刻的交通路况信息;由于所述历史时间段为预设时刻之前不同日期中的相同预设时间段,且由于获取的历史交通信息中包括与目标路段具有空间相关性的邻居路段的历史交通信息,从而使得历史交通数据具有时间相关性以及空间相关性,进而可以提高利用交通路况预测模型预测交通路况信息的准确性。
