The invention discloses a traffic sequence prediction method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a target area from a source city according to traffic data of the source city and a target city, and further constructing a virtual city; comparing the geographic data of the virtual city and the geographic data of the target city to obtain a network weight; training a prediction model based on the network weight, the virtual city and the time sequence data of the target city; and finally predicting the traffic sequence of the target city. According to the technical scheme, the virtual city is constructed according to the target area, so that more traffic data beneficial to prediction of the target city in the source city are kept in the virtual city, and traffic data migration is more stable and reasonable; the prediction model is trained based on the network weight, the virtual city and the time sequence data of the target city, so that the phenomenon of negative migration is relieved, and the accuracy and efficiency of traffic sequence prediction are improved; and finally, accurate and efficient traffic sequence prediction is realized through the prediction model.
本发明公开了一种交通序列预测方法、装置、电子设备及存储介质。该方法包括:根据源城市以及目标城市的交通数据,从源城市中确定目标区域,进而构建虚拟城市;比较虚拟城市与目标城市的地理数据得到网络权重;基于网络权重、虚拟城市以及目标城市的时序数据训练预测模型;最后预测目标城市的交通序列。上述技术方案根据目标区域构建虚拟城市,以在虚拟城市中保持源城市中更多有利于对目标城市预测的交通数据,使得交通数据迁移更稳定合理;通过基于网络权重、虚拟城市以及目标城市的时序数据训练预测模型,缓解了负迁移的现象,提高了交通序列预测的准确性和效率;最后通过预测模型实现了准确且高效的交通序列预测。
