北太平洋ルートにおける航空交通の到着間隔の調査

In general, a computer simulation is carried out for evaluating the safety level of a future oceanic air route system where the current separation minima are reduced. In the simulation, modeling arrival-interval distributions is required for generating pseudo traffic. This paper describes the results of survey and analyses on the arrival-interval distribution for the westbound traffic crossing the boundary between Tokyo flight information region (FIR) and Anchorage FIR in the NOPAC routes. A probability density function model which consists of a weighting sum of exponential distributions with different means is proposed for approximating the empirical arrival-interval distribution.
