The invention discloses a complex traffic flow prediction method based on dynamic graph convolution and interactive learning, and belongs to the technical field of intelligent traffic, and the method achieves the effective long-term traffic flow prediction through embedding a graph convolution network into an interactive learning structure, and capturing the time and space dependence at the same time. A new dynamic graph convolution method is used, a combined graph generated from an adaptive and learnable adjacent matrix in real time is used to capture spatial correlation changing in real time in a traffic network, then a space-time adaptive converter is integrated, global and local features can be extracted, and the spatial correlation is obtained. According to the method, the challenge of traffic flow prediction aiming at complex correlation and nonlinearity of urban traffic flow in time and space can be solved, the advantages of dynamic graph convolution and interactive learning are combined, a new efficient model of dynamic graph convolution and interactive network is provided, the dynamic spatial and temporal characteristics of the traffic flow are reflected, and the traffic flow prediction efficiency is improved. Therefore, traffic flow prediction can be realized more accurately.
