Future airspace needs to be flexible, dynamic and adaptable based on traffic demand,
equipage, and weather. Initial concepts focus on three core areas: 1) restructuring airspace …

At present, en-route flight traffic is carried out on a system of predefined routes with a low
number of intersections between aircraft trajectories. This enables the air traffic controllers to …

Air transportation systems are some of the most complex logistical systems imaginable. The
world's airlines transported over 2.2 billion passengers in 2008, and transported …

A flow-based modeling approach is proposed to identify candidate airspace for high-density
flow corridors. The input to the model is a set of projected user-preferred, wind optimal, and …

This paper presents a methodology to estimate the collision risk associated with a future air-
transportation concept called the flow corridor. This concept is designed to reduce …

Today's airspace structure and operational restrictions are rigidly defined, with heavy
linkage to navigational aids and airspace sectors that have evolved over time and usage …

Given its static and rigid structure, the current National Airspace System lacks the ability to
cope efficiently with the increasingly severe demand–capacity imbalances expected to …

Corridors-in-the-sky is a new airspace structure designed to accommodate high density
traffic by grou** flights with similar trajectories. Less air traffic controller workload is …

THE predicted growth in traffic demand over the next 20 years could result in increased
congestion and delays in the National Airspace System (NAS). Under the dynamic airspace …

Purpose–When large samples are used to estimate airport efficiency, clustering is a
necessary step before carrying out any benchmarking analysis. However, the existing …
