The invention discloses a highway toll station flow prediction method and system, and relates to the field of intelligent traffic management and big data analysis, and the method comprises the steps: collecting multi-source heterogeneous traffic data, carrying out the preprocessing, carrying out the feature extraction of the preprocessed multi-source heterogeneous traffic data, mapping the extracted features into a common feature space, and carrying out the prediction of the flow of a highway toll station. The method comprises the steps of performing feature fusion, generating a comprehensive feature vector, obtaining a traffic network diagram based on the comprehensive feature vector, constructing an STGATwE model according to the traffic network diagram, training the STGATwE model by using the comprehensive feature vector, adjusting parameters of the STGATwE model, generating a trained STGATwE model, inputting multi-source heterogeneous traffic data collected in real time into the trained STGATwE model, and obtaining a flow prediction result. By collecting multi-source heterogeneous traffic data and introducing an external influence factor mapping function, the data dimension is enriched, and the sensitivity to external factors is enhanced.
