Abstract: Continuously increasing traffic demand and gradually saturated airspace are promoting a transformation which will shift future air traffic management system to a refined management mode with Trajectory Based Operation (TBO) as its core. Conforming to the TBO concept and current air route structure in busy terminal airspace, traffic flow optimization models corresponding to short-cut directly fly arrival mode and merge-point arrival mode with TBO characterized are proposed respectively. Charles de Gaulle Airport is taken as an example to build the terminal airspace simulation environment. Based on actual flight plans and radar data, four-dimensional flight trajectories are generated and optimized by the two models. According to the simulation outcomes, analysis and comparisons of traffic flow characteristics for the two models are carried out. The results show that the models can effectively avoid potential aircraft conflicts and maintain a safe and efficient traffic flow operation in terminal airspace by implementing trajectory selection, time slot rescheduling, dynamic separation, sequence exchange, etc. It reveals traffic flow characteristics under the TBO mode and provides theoretical support for the future air traffic management strategy centered on the four-dimensional trajectory.

Key words: air traffic management, terminal airspace, trajectory-based operation, traffic flow characteristics, simulation and optimization
