Automated Conflict Resolution in Air Traffic Management

Abstract

Collision prevention strategy in ATM is not only a short-term coordination between safety and efficiency, but also a long-term planning for national policy of airspace and air transportation system. The optimization of system should be based on good command of equipment, staff, procedure and operation restriction to meet the real-time requirement and integrity. Essentially, collision prevention strategy in ATM consists in finding synthetic and effective automatized avoidance methods in order to reduce the possibility of dangerous approach or collision, of which the conflict detection, conflict resolution and resolution trajectory optimization are the key technology. This paper proposes a research on the standard of intelligent prevention of collision, and theory and methodology of its optimization from the systems engineering perspective. This paper describes thoroughly the decision-making procedure of ATC, establishes the optimized target for ATC's decision-making, and puts forward an optimization of conflict detection and conflict resolution between several aircrafts in 4D space. The medium and long term collision prevention strategy through adjusting speed or altitude and short-term collision prevention strategy through adjusting heading makes the intelligent ATC system a perfect one.
