This article describes a unified solution to three types of separation-assurance problems that
occur in en-route airspace: separation conflicts, arrival sequencing, and weather-cell …

En-route congestion causes delays in air traffic networks and will become more prominent
as air traffic demand will continue to increase yet airspace volume cannot grow. However …

Efficient airport surface operation is considered key to successful implementation of 4-D
trajectories. Here, an airport surface aircraft model is developed to improve simulation …

Changing preferences due to autonomous vehicles may cause air travelers to forgo their
local airports in favor of more preferred air service at large-hub, typically farther, airports in a …

This paper compares airspace design solutions for dynamically reconfiguring airspace in
response to nominal daily traffic volume fluctuation. Airspace designs from seven algorithmic …

The Airspace Concept Evaluation System (ACES) is a distributed, fast-time, flexible, gate-to-
gate modeling and simulation tool of the National Airspace that enables investigation of …

TODAY, most flight segments still must use the air traffic controller specified routes such as
jet routes, airways, and veryhigh-frequency omnidirectional radio range waypoints, instead …

IN THE national airspace system, high traffic demand and inefficient airspace designs cause
overloaded sectors. Because some overloads can be eliminated by redesigning sector …

arrival flights that were managed by an automated system were compared to the fuel …

An existing Mixed Integer Programming optimal sector design method is implemented,
analyzed, and improved. The original model is a powerful and convenient method of …
