The invention provides a regional bridge group traffic flow prediction method and device based on a full connection graph and double convolution, and relates to the technical field of time series data prediction. The method comprises the following steps: monitoring traffic flows of different bridge nodes in a regional bridge group to obtain original flow data of a two-dimensional data structure time sequence; performing data structure dimension raising processing on the original traffic flow data to obtain improved data of a three-dimensional data structure; training the model by using the improved data; according to the current improved data, performing feature extraction through a graph convolutional neural network to obtain space-time related features; capturing data periodicity through a two-dimensional convolutional network to obtain periodicity features; and splicing, fusing and inputting the time-space correlation features and the periodic features into a full-connection layer for prediction to obtain a traffic flow prediction result. The invention relates to a regional bridge group traffic flow prediction method based on a full connection graph and a double convolution multidimensional time sequence, and provides a basis for performance evolution prediction of bridges in a regional road network.
