Abstract

Abstract: In order to ensure safety of airport operation and detect opposite conflict behavior in time, an assessment model of opposite taxiing conflict was proposed. Airport operation procedure and dynamic taxiing process were abstracted, and conflict areas were defined with an integrated consideration of taxi section, jet range and other factors. Then, conflict risks were quantified and simulated based on real-time speed and distance. The results show that this model could quantitatively assess conflict risk of aircraft at both uniform and variable speed with head-to-head motion trend, and its risk value is proportional to length of opposite taxiing section, and inversely proportional to difference of aircraft's velocity and position. It is found that the model can predict conflict trend in advance which proves to be consistent with actual situation.

Key words: aircraft, opposite taxiing conflict, risk assessment, airport operation, simulation
