Controller Intervention Degree Evaluation of Intersection in Terminal Airspace
The intersections in the terminal airspace is an potential factor to cause flight conflicts. The possibility of conflict can be reflected directly from air controller intervention degree. Analyzing the controller intervention degree of intersection is a precise and efficient method to locate airspace congestion location in terminal airspace. After analyzing the historical data, improved density clustering method is used to determine the distribution of intersections in terminal airspace. The method of assessing the controller intervention degree is put forward through the statistics on the changes of the flight elements within certain time and range. The experimental results show that this method can obtain the distribution of conflict and controller pressure points in the terminal area, and is quite consistent with reality. The method can provide fast and accurate optimization basis and improvement direction for the airspace planning work.
