Aircraft taxiing route planning based on airport hotspots

摘要

In order to avoid airport surface hotspots, taxiing route planned for aircraft based on surface hotspots is proposed in this paper. Firstly, airport is abstracted into node-link model and aircraft taxiing avoidance mechanism is established. Then, a ground taxiing route optimization model which minimizes total taxiing time is proposed. A simulation is conducted based on a practical setting of 9 flights on runway 02L at a central-south airport. Simulation results indicate that total taxiing time is reduced by 243s after optimization and no taxiing conflict occurs. Meanwhile, the number of flight that taxi through hotspots area is reduced f, which effectively alleviates the risk level of hotspots and improves airport operation safety.
