The invention provides a traffic information prediction method and device, equipment and a medium, and relates to the technical field of data processing. The method comprises the following steps: constructing a distance relation matrix based on a distance relation between traffic nodes; traffic information vectors are constructed by using the traffic information corresponding to the traffic nodes, and a correlation coefficient matrix and a dynamic time warping matrix are respectively constructed based on linear correlation and an accumulated minimum distance between the traffic information vectors corresponding to different traffic nodes; fusing the distance relation matrix, the correlation coefficient matrix and the dynamic time warping matrix by using a learnable parameter and an activation function to obtain a fusion matrix; and performing feature extraction on the fusion matrix based on a pre-established prediction network to obtain predicted traffic information of the traffic nodes in the prediction time period. According to the technical scheme, the traffic information prediction accuracy can be improved.
