Toward Air Traffic Complexity Assessment in New Generation Air Traffic Management Systems
IEEE Transactions on Intelligent Transportation Systems, 2011The characterization of complex air traffic situations is an important issue in air traffic management (ATM). Within the current ground-based ATM system, complexity metrics have been introduced with the goal of evaluating the difficulty experienced by air traffic controllers in guaranteeing the appropriate aircraft separation in a sector.

PIGAT: Physics-Informed Graph Attention Transformer for Air Traffic State Prediction
IEEE transactions on intelligent transportation systems (Print)Efficient and resilient traffic management relies on accurate prediction of air traffic states. However, the complex spatial-temporal dependencies of air traffic networks make this task challenging. To address this issue, we propose a novel deep learning

Expansion of city scale, traffic modes, traffic congestion, and air pollution
, 2021In recent years, the number of large cities and the incidence of urban haze have been increasing. However, whether population growth inevitably leads to air pollution is controversial. The expansion of city scale is accompanied by changes in traffic mode

Deep learning based short-term air traffic flow prediction considering temporal–spatial correlation
Aerospace Science and Technology, 2019In order to improve the accuracy and stability of air traffic flow prediction, an end-to-end deep learning-based model is proposed in this paper. By analyzing spatial correlations of adjacent areas and temporal correlations of historical traffic on given

Vehicle emissions are responsible for a considerable share of urban air pollution concentrations. The traffic air quality index (TAQI) is proposed as a useful tool for evaluating air quality near roadways. The TAQI associates air quality with the equivalent emission from traffic sources and with street structure (roadway structure) as anthropogenic ...

Effects of work shifts on fatigue levels of air traffic controllers
Journal of Air Transport Management, 2019Fatigue is one of the most important issues since it is considered to be a potential risk factor for human error. Most research related to human fatigue in the aviation industry targets pilots, yet air traffic controllers also experience elevated levels ...
