INVESTIGATION OF CONFLICT CHARACTERISTICS AT AIRWAY INTERSECTIONS

Aircraft traffic has increased significantly in recent years leading to airway congestion and a need to better understand air conflicts. This paper deals with the estimation of the number and distribution of air conflicts. A stochastic model is presented that evaluates the number of conflicts for a spatial geometry of two intersecting airways using a simulation process. Investigators examined the effect of shape of the arrival distribution functions on the shape of the conflict distribution function and its variance. The variance of the number of conflicts is dependent on the aircraft-arrival distribution. Similarly, the shape of the distribution function of conflicts is dependent on the aircraft-arrival rate distribution. These associations are complex, since one airplane on one path can conflict with one or more airplanes on another path. The analysis is geared toward comparison of the simulation results with existing analytical results that are all planar with respect to airway geometry.
