Abstract:
In a large-volume, high-density traffic background, air traffic manifests fluid-like microscopical characteristics. The characteristics are formed by the micro tailing actions between individual aircraft. Aircraft headway refers to the time interval between successive flying aircraft in air traffic flow, which is one of the most important characteristics of air traffic flow. The variation in aircraft headway reveals the air traffic control behaviour. In this paper, we study the characteristics of air traffic control behaviours by analyzing radar tracks in a terminal maneuvering area. The headway in arrival traffic flow is measured after the determination of aircraft trailing relationships. The headway evolutionary characteristics for different control decisions and the headway evolutionary characteristics in different phase-states are discussed, and some interesting findings are gotten. This work may be helpful for scholars and managers in understanding the intrinsic nature of air traffic flow and in the development of intelligent assistant decision systems for air traffic management.
