With the rapid development of the air transport industry,the operating capacity of air routes is becoming increasingly saturated.In order to solve the imbalance between capacity and flow,many research institutions have put forward the concept of air traffic management for the next generation,among which the new airspace concept of tubular air routes has emerged.Based on the operation concept and model of the new tubular route in the future,combined with the relevant research on the connection method be-tween the traditional air route and the terminal area,this paper intends to establish the physical structure of the connection model,propose the operation mode of the aircraft in the tubular route and the fusion pro-gram,build a simulation platform of the tubular route for performance analysis,and make comprehensive use of probability theory,statistics and other theories.The influence mechanism and operation efficiency of different connection methods on traffic flow were studied.The research shows that the design of the tube-terminal control area connection model can carry the operation load in large flow,improve the average route capacity and flight operation efficiency,reduce the conflict rate and daily delay time of aircraft,while taking into account the route capacity and safety risks.
