Abstract The study of congestion evolution mechanism in terminal airspace is a vital measure to ensure the normal operation of terminal airspace. This paper divides congestion into two categories: its own structural causes and external causes, and establishes a corresponding analytical model for congestion formation and dissipation. Based on the characteristic indexes of traffic flow evolution and Greenshields theory, the cusp catastrophe analysis model for congestion mechanism is established. In order to verify the validity of the model, this study takes the Chengdu terminal airspace as the object and uses AirTOp software to generate simulation operation data. The results show that the designed model can effectively describe the macroscopic process of congestion evolution, and the mechanism of congestion evolution can be effectively analyzed through the changes of equivalent flow, density and wave speed in the segment.
