Effects of light and heavy workload on air traffic tactical operations: a hazard rate model

摘要

This paper introduces a class of event history analysis used to examine how the operations of an air traffic controlled change under light and heavy traffic workload. The analysis begins by assessing the hazard rate, h(t), of a transition (or spell) between the controller's communication and flight progress activities. H(t) is the instantaneous rate of going from one state (i.e. an activity of Communication or flight progress) to another in a unit of time, given that the Controller has been in the first state until time t.
