STOCHASTIC PROPERTIES OF CONFLICT FREQUENCY AT MULTIPLE CONNECTED AIR ROUTE INTERSECTIONS

Previous results regarding the stochastic properties of the frequency of conflict situations at a single intersection of two air routes have been extended to the case of multiple connected intersections. Such a situation occurs when more than one aircraft stream intersects with another aircraft stream. Examples include multiple discrete velocity groups of vehicles on routes, intersections in the horizontal plan involving more than two routes, and routes transitioning through altitude strata or flight levels. It is determined that the conflict frequency at multiple intersections connected with a common vehicle stream are correlated, and the expression for the covariance is derived. With these results, not only the mean, but the variance of conflict frequency for an ATC sector may be predicted from traffic-flow and route-geometry information, both of which are important parameters for sector capacity analyses.
