The invention discloses a traffic state prediction method. The method comprises the steps of generating traffic travel data based on traffic flow trajectory data of a target area in a historical time dimension; combining the initial traffic units according to the traffic trip data to obtain a target traffic zone; generating a historical traffic matrix corresponding to the target traffic zone based on the traffic trip data; inputting the historical traffic matrix into a traffic prediction model, and outputting a target traffic matrix predicted in a future time dimension through the traffic prediction model; and predicting the traffic state of the target area according to the target traffic matrix. The method can be applied to the traffic field, the initial traffic units are generated by acquiring the traffic travel data of the target area, and the initial traffic units are combined based on the traffic travel data to obtain more accurate traffic cells, so that the predicted target traffic matrix has very high accuracy, and the prediction accuracy of the target traffic matrix is improved. And the accuracy of the prediction result of the traffic state is effectively improved.
