Research on Road Network Congestion Propagation Based on Complex Network and SIR Model

Abstract

This paper analyzed the dynamic evolution process of road traffic network congestion from a holistic and macroscopic point of view, and establishes a road network congestion propagation model based on the similarity between traffic congestion propagation and infectious disease propagation and the topological structure information of roads. The model takes the road section as the research object, and analyzes the effect of different parameters on congestion propagation through simulation. The simulation results show that the road network congestion propagation model constructed in this paper is consistent with the actual situation, which can provide a new idea for road network congestion management and congestion prediction, and has certain practical application value.
