The invention relates to an urban traffic data prediction method based on causal classification depolarization, belongs to the technical field of spatio-temporal data mining, and provides an urban traffic data prediction method based on causal classification depolarization. The influence of urban spatio-temporal data distribution skewness on causal mining is corrected through causal intervention, a spatio-temporal causal relationship hidden in observation data is recovered, a causal graph is learned by adopting priori information such as a spatial proximity relationship and a time position, and a spatio-temporal causal transmission mechanism crossing different time slices is introduced to enhance spatio-temporal causal characterization, so that the causal mining accuracy is improved. Therefore, the accuracy and the robustness of urban traffic data prediction are remarkably improved, and the accuracy, the robustness and the generalization ability of the prediction model are effectively improved.
