Abstract:

Given consistent expanding airport size and increasing air traffic flow, accurately apprehending the traffic congestion situation in operation management becomes a vital problem. In China only a few airports忆average taxi out time is specified as the indicator of airport operation. However, it cannot recognize the difference between various combinations of gates and departure runways in one specific airport. The unimpeded taxi time is introduced as an optimum reference in FAA and EUROCONTROL in order to evaluate the level of inefficiencies in the taxi-out phase. Nevertheless, the value of unimpeded taxi time in US or Europe is not suitable for airports in China. Based on FAA and EUROCONTROL approaches, an improved one on which multiple linear regression models is built,is proposed to evaluate the unimpeded taxi time. Validaton of this approach with operational data in Beijing Capital International Airport proves its feasibility.

Key words: traffic congestion, taxi-out efficiency, unimpeded taxi time, regression analysis
