Data-driven modeling of air traffic flows for advanced Air Traffic Management
The Air Traffic Management (ATM) system enables air transportation by ensuring a safe and orderly air traffic flow. As the air transport demand has grown, ATM has become increasingly challenging, resulting in high levels of congestion, flight delays and environmental impacts. To sustain the …

Air Traffic Controllers’ Occupational Stress and Performance in the Future Air Traffic Management
… it is vital to understand its effects on air traffic controllers and the safety of the national airspace system. This study’s primary purpose is to determine how UAVs that operate in controlled airspace would influence air traffic controllers’ occupational stress and performance. In a …

Self-Reported Emotional States and Air Traffic Controller Operational Error Rates in Advanced Air Traffic Control Students
… to promote and mitigate aviation incidents. Air traffic controllers work in high stress environments, requiring them to make hundreds or even thousands of individual decisions in regard to aircraft positioning on a daily basis. All it takes is for one small operational error in order for an …

The impact of air traffic management automation on the human performance of air traffic controllers in aviation law
… in communication, navigation, surveillance and air traffic management (CNS/ATM) systems directly impact air traffic controllers (ATCs), who must interact with these technologies within a regulated framework. The hypothesis is that aligning these advancements with their governing international, …

Air traffic control using Virtual Stationary Automata
As air travel has become an essential part of modern life, the air traffic control system has become strained and overworked. This problem is occurring because the capacity of the current air traffic control system is severely limited by the capabilities of its human operators. Therefore, if we are …

Characterization and prediction of air traffic delays
… new model for predicting delays in the National Airspace System (NAS). The proposed model uses Random Forest (RF) algorithms, considering both temporal and network delay states as explanatory variables. In addition to local delay variables that describe the arrival or departure delay states of …

The stochastic air traffic flow management rerouting problem
… formulate a model for planning the rerouting of aircraft to alleviate en-route congestion, with system capacity being modeled stochastically. To overcome problems with tractability, we apply a Dantzig-Wolfe decomposition and present an efficient method for solving it. The decomposed formulation …

Optimizing neural networks for enhancing air traffic security
… a neural network to predict future positions of airplanes in the vicinity of airports. These predicted positions are then used to calculate future separation distances between pairs of airplanes. The predicted values of the separation distance are used to ensure adequate distances between …

Estimating the true extent of air traffic delays
Most air traffic delay measures assess delays relative to schedule. Over the past decades, however, airline schedules have been adjusted to take into account airspace congestion and yield better on-time performance. In that context, delay measures that are using scheduled times as a benchmark are …

The effect of scheduling on air traffic delay
… millions of dollars are being lost by major airlines each year because of the inability of high density air terminals to efficiently service all of the demands placed upon them during peak periods of demand. Up to the present time, studies involving congestion have been aimed primarily at the …
