Collision risk estimation on parallel airways

Abstract

In this paper, for purposes of airspace planning, by the theory of statistical-probabilistic and theory of traffic engineering a mathematical expression of the parallel airways based on the variable nominal distance and airspace planning parameters is given. By using the estimation formula proposed the average number of collisions between the parallel airways can be calculated and the impacts of airspace planning parameters on the collision risk can be shown. A method to characterize the collision risk when the aircraft are flying on parallel airways and the collision risk when the nominal distances on parallel airways are variable is given in the progress of airspace planning which may provide some theoretical basis for airspace planners to determine the lateral separation minimum, and may give some references basis for researchers of air traffic flow to study the capacity of airspace and air traffic controllers to keep airspace safe.
