OBJECTIVE To investigate whether exposure to aircraft noise increases the risk of hospitalization for cardiovascular diseases in older people (≥ 65 years) residing near airports. DESIGN Multi-airport retrospective study of approximately 6 million older people residing near airports in the United States. We superimposed contours of aircraft noise levels (in decibels, dB) for 89 airports for 20...

This paper focuses on the role which workload can play for work organisation in a future remote control tower center. Nowadays you can find a control tower next to each airport. A tower is equipped with a team of controllers which maintain the declared surface movement rate under all weather conditions within the aerodrome visibility operational level (AVOL) while maintaining the required level...

Effectively identifying an airport from satellite and aerial imagery is a challenging task. Traditional methods mainly focus on the use of multiple features for the detection of runways and some also adapt knowledge of airports, but the results are unsatisfactory and the usage limited. A new method is proposed to recognize airports from high-resolution optical images. This method involves the a...

Traditionally, in the field of air transportation management airlines have been the main actors in the process of deciding which new flights to open in a given airport, while airports acted only as the managers of the operations. The changes in the market due to the introduction of low cost companies, with the consequent reduction of airports fares, as well as the increase in density of regiona...

Airports are an ideal application area for simulation. The processes are in a continuous state of change, are complex and stochastic, involve many moving objects, and require a good performance that can be measured in several different performance indicators. Within airports, but also between airports, the same kind of questions are answered over and over again. Often, however, new simulation m...

Our project analyzes the United States domestic airport network. We attempt to determine which airports are most vital in maintaining the underlying infrastructure for all domestic flights within the United States. To perform our analysis, we use data from the first quarter of 2010 and use several methods and algorithms that are frequently used in network science. Using these statistics, we ide...

Airport planning is shifting from the traditional pattern driven by long-term point forecasts, high standards, and established clients to that of recognizing great forecast uncertainty, many standards and changeable clients. This is a consequence of economic deregulation of aviation and the rise of lowcost airlines. Low-cost airlines are becoming significant factors in airport planning. Their r...

Airport efficiency is an area of increasing interest to academics, policy makers and practitioners. This has resulted in a body of literature applying various econometric techniques to compare efficiency between different samples of airports. This paper uses the multi-criteria decision making method Analytic Hierarchy Process (AHP) to incorporate the weightings of input and output variables int...

Aircraft taxiing on the surface contribute significantly to the fuel burn and emissions at airports. This report is an overview of PARTNER’s Project 21, which tries to identify promising opportunities for surface optimization to reduce surface emissions at airports, estimate the potential benefits of these strategies, and assess the critical implementation barriers that need to be overcome prio...
