The invention provides a traffic flow prediction method and device based on time-space synchronization graph aggregation. The method comprises the following steps: acquiring a first historical traffic flow of each station in a to-be-predicted area; inputting the first historical traffic flow of each station into a traffic flow prediction model to obtain a predicted traffic flow of each station output by the traffic flow prediction model; the traffic flow prediction model is obtained based on second historical traffic flow training of each station; the traffic flow prediction model is used for extracting spatio-temporal characteristics corresponding to each station based on the first historical traffic flow of each station, and performing traffic flow prediction based on the spatio-temporal characteristics corresponding to each station; the spatio-temporal characteristics are synchronously extracted by a spatio-temporal synchronization graph aggregation module in the traffic flow prediction model. According to the method and the device provided by the invention, the modeling process is optimized, the prediction performance of the traffic flow is greatly improved, and end-to-end traffic flow prediction is realized.
