The invention relates to the technical field of intelligent traffic, in particular to a smart city traffic management method and system based on multi-source data fusion, and the method comprises the following steps: carrying out the network modeling through a graph theory and a network analysis algorithm based on the geographic information of a city road network, and recognizing key nodes and paths in the network through the network topology structure analysis, and determining a key intersection in the traffic network by using node degree centrality analysis, identifying a key channel in the traffic flow, and generating a traffic network key structure chart. According to the method, through the graph theory and the network analysis algorithm, the traffic network structure is captured, key nodes are identified, flow management and a graph neural network are optimized, graph convolution and a graph attention network are combined, the accuracy of traffic flow and speed prediction is improved, analysis on traffic flow changes is enhanced through the chaos theory, and particularly, the method has the advantage that the traffic flow and speed prediction accuracy is improved in the aspect of sudden congestion prediction. Through game theory model and time sequence analysis, implementation of long-term trend prediction and intelligent traffic management is enhanced, and the overall efficiency of the traffic network is improved.
