The invention relates to the technical field of intelligent traffic, and provides a road congestion propagation prediction method based on a double-layer hypergraph model, and the method comprises the steps: constructing an FC-ISQ double-layer traffic congestion propagation model based on a hypergraph; determining a network layer of the model as a traffic road layer and a traffic information spreading layer; establishing a heterogeneous differential equation set of the model and verifying the positive property and the bounded property of a model solution; calculating a basic regeneration number R0 of the model, and taking the basic regeneration number R0 as a threshold value for judging whether the traffic jam is automatically dissipated or not; performing numerical simulation verification on the model; through simulation, prediction results of each group of the model under different initial parameter settings are obtained, and visual prediction of propagation trends and propagation conditions of traffic congestion under different conditions is realized. According to the invention, by constructing the FC-ISQ double-layer traffic jam propagation model based on the hypergraph, the dynamic propagation rule of the traffic jam state is systematically revealed.
