The invention discloses a traffic flow prediction method. The method comprises steps of obtaining traffic condition data collected by a plurality of nodes and the positioning information correspondingto each node; calculating a space vector corresponding to each node according to the positioning information, and generating a space-time vector according to the traffic condition data and the spacevector; calculating a space weighted value and a time weighted value corresponding to each node according to the space-time vector and the traffic condition data, performing gating fusion of the spaceweighted value and the time weighted value to obtain a fusion value, and predicting future traffic flow according to the fusion value. The method is advantaged in that the method can achieve accurateprediction of the future traffic conditions, and improves the reference of the prediction result.
