Abstract
Currently, the surface topology at large domestic airports with increasing traffic flow is becoming more complex. Taxiing conflicts grow as well. This paper proposed a strategy based on aircraft priority to solve the problem. Under the premise of ensuring aircraft priority, this strategy resolved the problem reasonably and improved the safety and efficiency of airport operation. With the purpose of minimizing time cost of all aircraft, an aircraft taxiing model was built. Simulation results showed the advantages of this strategy. Compared with a common conflict resolution strategy, taxiing routes of 9 aircraft changed. The total waiting time was reduced by 50% and the running time was reduced by 43.6s. In addition, to ensure taxiing efficiency of high-priority aircraft, low-priority aircraft tended to choose more tortuous routes when choosing suboptimal alternative routes.
Highlights
With the increase of air traffic, available resources during busy period of large airports can’t meet the demand of air transport, which causes much congestion
In this paper, in combination with the accurate airport surface structure, we established a dynamic taxiing model of aircraft based on priority
The model aimed at minimizing time cost of all aircraft
Summary
With the increase of air traffic, available resources during busy period of large airports can’t meet the demand of air transport, which causes much congestion. INDEX TERMS Aircraft priority, dynamic taxiing, rolling horizon, taxiing conflict resolution strategy. Cost rate, and a new aircraft taxiing conflict resolution strategy considering suboptimal alternative taxiing paths are proposed.
