The invention relates to a traffic jam propagation mode perception and visual analysis method, belongs to the technical field of electric digital data processing, and provides a traffic jam propagation visual analysis method based on graph mining, which allows interactive exploration of urban road jam propagation rules and improves the traffic jam propagation efficiency. And field experts are helped to mine traffic jam propagation rules from large-scale traffic data, and time-space factors of jam propagation are analyzed and explained. In the aspect of congestion propagation rule mining, the method allows road network topology information to be integrated to identify a congestion propagation relationship from massive traffic data, and introduces a graph neural network to characterize and cluster congestion and congestion propagation, thereby effectively discovering a traffic congestion propagation mode; in the aspect of perception and explanation of the congestion propagation mode, the method provides a flexible visual analysis process, a visual view for displaying space-time factors of the congestion propagation mode is integrated into an interactive visual analysis system, and field experts are allowed to perform deep analysis of congestion propagation at multiple levels.
