MODELS FOR ESTIMATING THE NUMBER OF CONFLICTS PERCEIVED BY AIR TRAFFIC CONTROLLERS

This research seeks to define and estimate the frequency of aircraft interactions (called conflicts) which entail controller intervention. The task of conflict detection is viewed as a stimulus-response process in which the strength of stimulation is a particular closest-approach separation between aircraft, and the corresponding probability of response is the fraction of times controllers judge that separation to be a potential violation of the 5 nautical mile minimum separation standard. Data from human-factors studies of air traffic control are used to estimate response probabilities for a wide range of closest-approach separations. Two empirical models are derived for estimating the number of conflicts.
