Apron Conflict Prediction and Avoidance for Aircraft in Large Airport
Abstract— In order to ensure the safe operation of apron, it is necessary to implement apron control system
integrated with advanced movement conflict control algorithm. Six classes of apron conflicts that may occur
in apron operation are summarized, and the corresponding characteristics are analyzed in detail. The
approach for constructing static network graph (SNG) based on virtual control node, and dynamic network
graph (DNG) for aircraft apron movement are provided with the prior information on taxi routes, respectively.
The concept of apron movement cycle, cycle chain, and shareable unidirectional route in DNG are proposed,
and the apron conflict prediction and avoidance algorithm was proposed for apron conflict type 1-4. Lastly,
the effectiveness of the proposed algorithm was validated through numerical study and simulation
experiment.
Index Terms— airport, apron, conflict prediction, conflict avoidance.
