| Abstract |
This paper deals with the estimation of the number and distribution of air conflicts at intersecting air routes. A conflict occurs when the spatial separation between two or more airplanes falls below a specified threshold. The number of conflicts may serve as a measure of the controller's workload and is an important measure of the air traffic control system's performance. Existing analytical models can solve for either simple planar configuration of airways and complex stochastic arrivals, or complex airway geometry and rather simple assumption of constant aircraft arrivals, but not both. A simulation model was developed in order to cope with three-dimensional spatial geometry of airway intersections, and to account for different aircraft arrival distributions on the airways. The simulation model is first developed for a simple configuration of two intersecting airways, and later extended to cope with a complex airway system composed of multiple intersecting paths. The simulation model includes a simple module which computes the delay caused by correction maneuvres due to potential conflicts. |
