Application of DDPG-based Collision Avoidance Algorithm in Air Traffic Control

In order to avoid conflicts in the air traffic scenario, this paper proposed a collision avoidance method based on deep deterministic policy gradient (DDPG). Before the entering aircraft reaches the boundary of the sector, a proper heading angle is obtained by using the proposed algorithm to guarantee a conflict free condition for all aircraft. The performance of the proposed algorithm is verified by numerical simulations. The results of the numerical simulations show that the entering aircraft is successfully guided in a sector to avoid conflicts and reaches the destination with the shortest distance, furthermore, the proposed algorithm takes less time.
