The invention discloses a traffic flow prediction method based on multi-model network coupling. The method comprises the following steps: processing and inputting road traffic flow original data; inputting the data into a linear layer for preprocessing to obtain linear transformation; inputting into Encoder, and extracting spatial dependency and time dependency; inputting an output result of the encoder into AdjostBlock to extract local features and enhance context information; summing the output result of the AdjostBlock and the original data to obtain a residual error, and taking the residual error as the input data of Decoder to carry out subsequent learning; an output result of the decoder is used as Query data of cross attention, and an output result of the encoder is used as Key data and Value data to be sent into the cross attention to process complex sequence data and then is input into a full connection layer to obtain a final prediction result. According to the invention, the accuracy of traffic flow prediction data prediction can be improved.
