Operations relevant for air traffic management are based on procedures communicated through speech commands. These procedures are human centric, thus un-automated. Following predictions of air traffic growth forecasts, air traffic will increase no matter which forecast model is taken into account. High density air traffic areas become inefficient to handle through un-automated procedures. As a ...

Controller workload is a key factor in limiting en route air traffic capacity. Past efforts to quantify and predict workload have resulted in identifying objective metrics that correlate well with subjective workload ratings during current air traffic control operations. Although these metrics provide a reasonable statistical fit to existing data, they do not provide a good mechanism for estima...

BACKGROUND There is relatively little evidence of health effects of long-term exposure to traffic-related pollution in susceptible populations. We investigated whether long-term exposure to traffic air and noise pollution was associated with all-cause mortality or hospital readmission for myocardial infarction (MI) among survivors of hospital admission for MI. METHODS Patients from the Myocar...

Aircraft noise is a major obstacle to the growth of aviation. This thesis presents an adaptive onboard real-time optimization algorithm and an Air Traffic Control simulation model that can minimize the aircraft approach noise and meet air traffic control targets and restrictions. The adaptive real-time optimization algorithm uses dynamic programming, nonlinear optimization, and receding horizon...

Potential growth in the commercial space transportation industry, coupled with an expected doubling of air traffic operations over the next 10 years, could place additional safety and capacity demands on the National Airspace System (NAS). The Space and Air Traffic Management System (SATMS) is a proposed framework of operations designed to accommodate future commercial space operations within t...

Congestion has plagued air traffic in the US and in Europe for nearly 20 years. To protect air traffic control from overloads, air traffic flow management tries to anticipate and prevent overloads and limit resulting delays. This paper focuses on understanding the requirements for developing re-routing decision support systems (DSS). It identifies participants in re-routing decisions and invest...

This is a substantial and complex project that will need to accommodate sometimes disparate civil and defence operational requirements, provide a base system that can readily incorporate new software functions to meet Australia's future air traffic demands, and achieve operational and financial efficiencies for both organisations. Over the last five or so years, Airservices Australia and the RA...

Urban air pollution is one of the major environmental problems faced by the developing countries. Studies in large Indian cities revealed that ambient air pollution concentrations are at such levels where it can cause serious health impacts. Lucknow, a fast growing city is not an exception to this. Researchers from the city have studied various aspects of air pollution during the last one and h...

This paper presents a methodology for analysing Air Traffic Incidents based on an estimate of the probability of an Air Traffic Incident developing into an Air Traffic Accident (Air Traffic Incidents are officially defined as events which are dangerous but without a catastrophic impact). A new approach is presented as previous research in this area has focused more on defining accident occurren...

Background and Objective: Bioaerosols as small particles enter the body by inhalation and lead to respiratory diseases based on type, concentration, and exposure time. In sensitive workplaces such as medical centers, it is necessary to pay attention to the type and population of these pollutants and the possibility of nosocomial infections. In the present study, the population and type of bioae...
