Airspace behavior modeling considering flight intent

Airspace's various reactions towards the change of traffic patterns make it difficult to predict its performance for design and optimization. Especially as demands for use of airspace increase rapidly and preferred trajectories own higher priority, how to arrange the traffic and configure the airspace needs more attention to understand airspace behavior confronted with the traffic considering flight intent. The paper first analyzes the phenomena found in traffic complexity modeling and outlines them with several new hypotheses. Afterwards, we propose a new airspace model describing its behavior as repulsive and attractive force against corresponding traffic pattern, and further analyzes this model with a typical three routes en-route structure for re-route decision making. By calculating global airspace complexity and adjusting the aircraft's heading and clearance interval period, we can get the certain critical values for re-route and validate the airspace behavior model.
