Abstract:

This paper is a continuation of works presented at CIMCA 2004 and 23rd DASC (2004) conferences, where two algorithms were introduced, allocating optimal separated 3D-trajectories to the main traffic flows. The reader may also refer to the PhD thesis of the first author, in french, for more details. In the paper presented at CIMCA, these algorithms -- an A* algorithm for the sequential strategy, and an evolutionary algorithm for the global optimization -- were tried on a toy problem, and the two strategies were compared. In the paper presented at DASC, the algorithms were again briefly introduced and illustrated on the same toy problem, and then applied to real traffic data, using operational aircraft performances, but with only one 3D-trajectory per flow. In this paper, we present more realistic models of 3D-flows, with several trajectories per origin-destination link. The 3D-separation concept is then assessed by comparing the conflicts detected in a traffic of reference, with the conflicts detected when the aircraft belonging to the main traffic flows follow separated 3D-trajectories.

Keywords: Air traffic flows optimization, 3D-separation, Evolutionary algorithms, A*, HEATS-3D
