Predictor of Airport Runway Capacity (PARC), Phase I

Active Technology Project

Project Introduction

Estimates of arrival and departure capacities of individual airport runways are used to predict occurrences of demand-capacity imbalance, and to meter arrivals and departures to balance runway demand with capacity. Inaccurate estimates incorrectly identify demand-capacity, imbalance time periods and metering solutions; resulting in underutilized runways or excessive traffic congestion. Accurate predictions enable maximizing airport and flight efficiency. The Predictor of Airport Runway Capacity (PARC) forecasts the future capacities of individual airport runways under specified operating conditions and a time horizon. PARC uses historical operations data to create and update statistical Bayesian network (BN) models of inter-aircraft spacing, accounting for influencing factors. The BN models are used in Monte-Carlo simulations of airport runway traffic to predict their arrival and departure capacities for the specified operating conditions and scheduled traffic. Traffic managers use PARC's capacity estimates to implement metering programs to efficiently balance runway demand with capacity. For example, forecast weather proximate to Charlotte-Douglas International Airport (CLT) will change the prevailing wind direction, ceiling, and Runway Visual Range (RVR), requiring changing the airport runway configuration from South Flow to North Flow and the operational flight rules from visual to marginal. Traffic planners want to know if these changes will cause excessive traffic congestion warranting implementation of a departure metering program. PARC determines that the number of scheduled departures will exceed capacity on runway 36C under the forecasted runway configuration, visibility, and traffic conditions. The traffic planners implement metering of runway 36C departures using PARC's runway capacity estimate. Because the estimated runway capacity is accurate, metering neither starves the runways of flights nor creates excessive runway departure queues. More »
