Aircraft taxiing is the most important part of airport operation,and shortening taxiing time is also the main key to improve airport operation efficiency.In order to realize the efficient operation of the airport and change the current situation of relying only on manual apron control,this paper,aiming at the special environment of aircraft taxiing,uses the improved SARSA algorithm to plan the aircraft's taxiing path,and verifies through simulation that the algorithm is superior to the traditional SARSA algorithm in terms of planning path length and iteration times,which can provide better decision-making assistance and reference for controllers.Efficiently plan shorter paths.
