Collaborative Modeling And Simulation Of Traffic Flow In Multi-airport Terminal Area

Terminal area as the starting point and destination of the flight activities, not only the airspace structure is complex and aircraft state changes frequently, especially in multi-airport terminal area, airspace coupling, aircraft intersection, separation and maneuvering operations are running in the terminal area caused uncertain effect. In view of the contradiction analysis of the current typical multi airport systems, the operation of the terminal area is not only restricted by the complex airspace resources, but also has more obvious influence on the time characteristics of the approach and departure traffic flow. Therefore, this paper studies the operation of terminal area based on the space-time resources of terminal area.Based on the analysis of operating characteristics of terminal area, summarized the time space resources on the arrival and departure traffic flow with relaxation phenomena modeling studies. The operation of terminal area output index based on established terminal operation efficiency evaluation model. The paper use the intelligent simulation platform, AirTOp, established three-dimensional scene of Chongqing terminal; the arrival and departure traffic flow constraint model of spatial data of arrival and departure of traffic flow operation constraints; using statistical real flight information on the airspace structure and constraints was conducted to validate the analysis. The simulation model was used to evaluate the operational efficiency of Chongqing terminal area, and the basic characteristics of the traffic flow and the operation efficiency of the terminal area were simulated and analyzed by using the evaluation model.Simulation results show that a certain relationship between the efficiency of the airport terminal area and more traffic flow between providing a certain reference value for the operation mode and method of multi-airport terminal area.
