Taxiway connects parking spot and runway, it takes an important role in airport surface scheduling. In order to improve the efficiency of airport schedule and ensure the flight safety, taxing optimization were studied. In this paper improved A* algorithm is proposed to research inbound and outbound flight route optimization, we consider not only distance information, but direction information when we search the path. Meanwhile we make sure taxi conflict free and globe flight taxi time cost lowest. Three conflicts are defined and time Gantt chart is used to check the taxiing conflict to realize taxi conflict free. Chongqing jiangbei airport as simulation model for algorithm analysis, the result show that the method is feasible and provides decision support for hub airports taxi scheduling.
