The invention provides a traffic information prediction method and device, equipment and a storage medium, and relates to the field of data processing. The method comprises the steps: acquiring a target city traffic road map, dividing the target city traffic road map into a plurality of target sub-maps, enabling the plurality of target sub-maps and corresponding target traffic state information to form target input data, and finally, inputting the target input data into a pre-trained traffic information prediction model to obtain a traffic information prediction value, wherein the traffic information prediction model is obtained by training a source city traffic road map in advance, and the number of nodes of the target city traffic road map is less than the number of nodes of the source city traffic road network. The traffic information prediction model is trained by using the source city traffic road network data with sufficient data volume, and then the traffic information prediction model is applied to the target city with less data volume, so that the traffic information prediction precision and prediction efficiency of the target city can be remarkably improved.
本发明提出一种交通信息预测方法、装置、设备及存储介质,涉及数据处理领域,其中方法包括:通过获取目标城市交通路图,并将目标城市交通路图划分成多个目标子图,然后将多个目标子图以及对应的目标交通状态信息组成目标输入数据,最后将目标输入数据输入预先训练好的交通信息预测模型中,得到交通信息预测值,其中,交通信息预测模型预先由源城市交通路图训练得到,目标城市交通路图的节点数少于源城市交通路网的节点数。利用数据量充足的源城市交通路网数据训练交通信息预测模型,然后将其应用于数据量较少的目标城市,能够显著提高目标城市的交通信息预测精度和预测效率。
