The design of future air traffic management (ATM) systems appears as a grand challenge. Because of its very large scale, complexity, and dynamicity, we believe that the future of air traffic management lies in hybrid distributed cooperative control systems, including human experts (air traffic controllers) and also intelligent computer support through artificial agents. Such artificial agents c...
Deficient safety occurrence reporting by air traffic controllers is an important issue in many air traffic organizations. To understand the reasons for not reporting, practitioners formulated a number of hypotheses, which are difficult to verify manually. To perform automated, formally-based verification of the hypotheses an agent-based modeling and simulation approach is proposed in this paper...
The global Air Traffic Management (ATM) system represents one of the most complex human-machine systems known. As the system has evolved in step with traffic demands, automation has been increasingly called upon to augment the capacities of the human operator, namely the air traffic controller. Future generations of ATM automation seek to augment, or even replace, such human faculties as decisi...
BACKGROUND Cross-sectional and ecological studies indicate that air pollution may be a risk factor for type 2 diabetes, but prospective data are lacking. OBJECTIVE We examined the association between traffic-related air pollution and incident type 2 diabetes. DESIGN Between 1985 and 1994, cross-sectional surveys were performed in the highly industrialized Ruhr district (West Germany); a fol...

Background and Aim: High concentrations of particulate matter-25 (PM2.5) have been the cause of the unhealthiest days in Tehran, Iran in recent years. This study was conducted with the aim of the spatio-temporal analysis of traffic volume and its relationship with PM2.5 pollutant concentrations in Tehran metropolis, Tehran during 2015-2018, using the Geographic Information System (GIS). Materi...
BACKGROUND Traffic exposure is a major contributor to ambient air pollution for people living close to busy roads. The relationship between traffic exposure and lung function remains inconclusive in adults. METHODS A cross-sectional study was conducted to investigate the association between traffic exposure and lung function in the Atherosclerosis Risk in Communities (ARIC) study, a community...
# 12 This issue of the European Respiratory Journal contains two papers that contribute to a growing body of evidence incriminating traffic fumes in respiratory disease. NICOLAI et al. [1] report a cross-sectional study that finds significant associations between traffic counts and exposure to traffic-related air pollution on the one hand and current asthma, wheeze and cough on the other. In a ...
