Integration of an Aggregate Flow Model with a Traffic Flow Simulator

Abstract

This paper describes a research and integration effort to develop computational tools to assess the performance of the National Airspace System (NAS). The problem of interest is focused on the en route airspace and how restrictions to aircraft movement are applied by air traffic controllers and traffic managers in response to demand overages or capacity shortfalls in sectors of airspace. To estimate and assess the efficiency of air traffic control responses, we apply the Large-capacity Cell Transmission Model (CTM(L)), which models the airspace system and its capacity constraints as a linear time invariant dynamical system, in which the state is a vector of aggregate aircraft counts. A mixed integer program is solved to minimize the control and delay of aircraft. We describe the integration of CTM(L) with NASA’s Future ATM Concepts Evaluation Tool (FACET). Using delay predictions, system metrics, and a visualization of the aggregated network, we apply the integrated environment to analyze and propose Traffic Flow Management (TFM) solutions for weather disturbances.
