The invention discloses a traffic flow prediction model training method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring historical traffic flow data, historical traffic density data and historical traffic network topology structure data; performing deep learning prediction based on the historical traffic flow data, the historical traffic density data and the historical traffic network topology structure data to obtain a first flow prediction result; performing cross attention mapping on the historical traffic flow data and the historical traffic density data to obtain a second flow prediction result; and determining model loss based on the first flow prediction result and the second flow prediction result, updating initial neural network parameters based on the model loss until a model training stop condition is satisfied, and obtaining a traffic flow prediction model. According to the technical scheme, the generalization of the prediction precision of the traffic flow prediction model is improved.
