Hierarchical Behavior Models for Characterizing Trajectories within Terminal Airspace
Flight trajectories in terminal airspace, ranging from highly controlled airports to untowered airports, exhibit repeatable patterns. These patterns, or behaviors, may often contain sub-patterns, suggesting that the nature of aircraft behaviors in terminal airspace is hierarchical. While current …

Optimizing Integrated Airport Surface and Terminal Airspace Operations under Uncertainty
In airports and surrounding terminal airspaces, the integration of surface, arrival and departure scheduling and routing have the potential to improve the operations efficiency. Moreover, because both the airport surface and the terminal airspace are often altered by random perturbations, the …

Airport Performance Metrics Analysis: Application to Terminal Airspace, Deicing, and Throughput
… the operational performance of the National Airspace System (NAS), where they analyze trends in the aviation industry to help develop strategies for a more efficient air transportation system. To measure the performance of various elements of the aviation system, the FAA and the International …

Optimization of airport terminal-area air traffic operations under uncertain weather conditions
… and widespread disruptions in the U.S. National Airspace System, especially during summer. Although Air Traffic Flow Management algorithms exist to schedule and route traffic in the face of disruptions, they require reliable forecasts of airspace capacity. However, there exists a gap between the …

Prediction of terminal-area weather penetration based on operational factors
… However, the degree to which weather impacts airspace capacity, particularly within the terminal region, is not well understood. Understanding how weather impacts terminal area capacity will be important for quantifying the uncertainty inherent in weather forecasting and developing an optimal …

Least-cost ground holding strategies with departure and arrival delay uncertainties
… time by which each flight should arrive at the terminal airspace of its airport of destination. It will then be up to the airlines to determine the times at which their flights should leave the gates at their airports of origin, in order to meet the CTAs at the airport of destination. In other …

A bi-level system dynamics modeling framework to evaluate costs and benefits of implementing Controller Pilot Data Link Communications and Decision Support Tools in a non-integrated and integrated scenario
… simulates air traffic in the enroute sector and terminal airspace for a single day and captures the measures of effectiveness at a microscopic level and feeds its output to the macroscopic annual model which then runs over the entire life cycle of the system. Airspace dwell time benefit data from …

Data-driven modeling of air traffic flows for advanced Air Traffic Management
… assist human decision-makers to deliver improved airspace design and traffic management solutions. This thesis presents a data-driven approach to modeling air traffic flows and analyzes its contribution to supporting system level ATM decision-making. A data analytics framework is proposed for …

Maximising runway capacity by mid-term prediction of runway configuration and aircraft sequencing using machine learning
… sequencing model is to incorporate the Standard Terminal Arrival Routes (STAR) for path planning and sequencing of arriving aircraft at Final Approach Fix (FAF) and departing aircraft sequence at the runway threshold. The simulation result demonstrates that the model can increase up to 15% of the …

A strategic planning approach for the operational-environmental problem of air transportation system terminal areas
… phenomenon is particularly exacerbated in the terminal area of major airports which have inevitably become operational choke points. On the other hand the environmental impact of air transportation, embodied primarily by the emissions and noise caused by aircraft operations, has also grown as a …
