A STOCHASTIC MODEL OF CONTROLLED AIRWAY TRAFFIC
The model presented in this paper may be used to estimate the expected number of overtake, crossing and merging conflicts at one flight level of an airway network. In addition, procedures are described for estimating the workload and saturation capacities of the network. A number of simplifying assumptions facilitate the analysis. Among these are (1) poisson arrival processes at all points, (2) constant aircraft velocities, and (3) aircraft paths that are coincident with charted airways, or otherwise predictable straight line segments. Each conflict model is essentially a conditional probability model given a particular pair of aircraft types which is then summed up over all possible aircraft-type pairs to obtain the unconditional conflict probabilities. A discussion of possible extensions of the model is included at the end of the report.
