Real-Time Calculation and Adaption of Conflict-Free Aircraft Ground Trajectories

Abstract

To improve the quality of airport surface operations and to pave the way for more autonomous systems, the calculation and adaptation of ground trajectories for aircraft is the backbone for every improvement. These trajectories should be conflict free and easily adaptable to changing conditions in real-time, but on the other hand optimized regarding configurable criteria. This paper describes how this can be achieved using artificial intelligence, especially a multiobjective A* algorithm coupled with a genetic algorithm. The genetic algorithm uses a flexible objective function that can be used to tune the resulting trajectories to the specific needs of the airport/air navigation service provider.
