On Capacity Estimation and Capacity-Safety Relationship in an Air Transportation Network
Air transportation is a complex system of interlinked distributed networks in which different components have their own constraints and performance measures. For example, an airport network in which each airport is treated as a node and models the departures/arrivals of flights as links considers …

Data-driven modeling and analysis of the U.S. air transportation network and its resilience to extreme events
… for analyzing and predicting delays of an air transportation network using publicly available data. The first part of this thesis details methods to quantify the resilience of the network. Traditionally, network metrics rely on removal of nodes heuristically to measure the resilience of the …

The effects of capacity discipline on smaller U.S. airports : trends in service, connectivity, and fares
… flights, seats, and available seat-miles, airlines reduced capacity at airports across the United States from 2007-2012 in response to a global economic downturn and high and volatile fuel prices. Despite an economic recovery and more stable fuel prices, airlines continued to keep domestic …

Scalability of the air transportation system and development of multi-airport systems : a worldwide perspective
With the growing demand for air transportation and the limited ability to increase capacity at some key points in the air transportation system, there are concerns that in the future the system will not scale to meet demand. This situation will result in the generation and the propagation of delays …

A Model to Assess the Mobility of the National Airpspace System (NAS)
One of the ways to define mobility in a transportation system is total travel time for all travelers using the transportation network. A good assessment of the mobility is essential for knowing the points of congestion in the network and the factors responsible for the congestion. Also the change …

Anomalous transport in complex networks
… consequence of the topological structure of the network and the physical mechanisms underlying the transport dynamics. We study transport by advection and diffusion in scale-free and Erdős-Rényi networks. Using stochastic particle simulations, we find anomalous (nonlinear) scaling of the mean …

Risk Management in Air Traffic Applications: Data-Driven Modeling, Prediction, and Generation of Realistic Weather Disruptions and Other Unfavorable Conditions
… between weather and disruptions in complex air transportation network is important to the design and evaluation of preemptive measures and responses taken by air traffic managers. However, the occurrence of disruptive weather events is often rather limited compared to the amount of data …

Spectral Models for Air Transportation Networks
… result in widespread disruptions across the air transportation network. In order to engineer resilience and design better proactive mitigation strategies, it is important to identify, characterize, and control the effects of such disruptions. A more resilient and well-prepared air …

The impacts of aviation emissions on human health through changes in air quality and UV irradiance
World-wide demand for air transportation is rising steadily. The air transportation network may be limited by aviation's growing environmental impacts. These impacts take the form of climate impacts, noise impacts, and health impacts, the latter of which are addressed in this thesis. Aircraft …

Improvement of terminal area capacity in the New York airspace
The New York airspace is the most congested in the U.S. air transportation network. Increasing capacity in this area is critical to ensure the balanced growth of traffic across the U.S. This study compares the total measured runway capacity at the New York airports with the achieved throughput of …

Data-centric methods for optimization and pattern discovery in networked systems
… data-driven solutions to problems in operational networks. The first problem is concerned with assessing the resilience of the US air transportation network from an operational perspective. As a complex network comprising over 5,000 public airports and countless interfaces with other …

The influence of runway occupancy time and wake vortex separation requirements on runway throughput
Air traffic growth in the U.S. has led to runway capacity constraints in the air transportation network. There has been limited new construction of runways due to land availability. One approach to increase capacity of existing runways is to reduce inter-arrival separations during the final …

Networked control of aircraft operations at airports and in terminal areas
… this thesis is to develop a control strategy for airport operations that integrates the management of arrivals and departures. The strategy is based on four central ideas: (1) the objective of reducing aircraft flight times, taxi times and fuel burn, (2) the emphasis on developing models using …

The impact of aircraft design reference mission on fuel efficiency in the air transportation system
Existing commercial aircraft are designed for high mission flexibility, which results in decreased fuel efficiency throughout the operational life of an aircraft. The objective of this research is to quantify the impact of this practice and other non-optimal emergent behaviors of the current global …

An Agent-based Model for Airline Evolution, Competition, and Airport Congestion
The air transportation system has grown significantly during the past few decades. The demand for air travel has increased tremendously as compared to the increase in the supply. The air transportation system can be divided into four subsystems: airports, airlines, air traffic control, and …
