Towards more sustainable airfield pavements using life-cycle assessment of design alternatives

2020

Airports are critical infrastructures and their success is paramount to development through tourism, trade and connectivity. Within the airport, the runway pavement must always be in a pristine condition. Consequently, pavement design and maintenance decisions are vital. Authorities must make decisions concerning preferred materials for design and maintenance. Decisions should be balanced by both economic and environmental factors. This paper considers a case study at Falcone Borsellino Airport (PMO), Palermo, Italy, where air traffic has been steadily increasing. Different pavements are proposed: flexible Asphaltic concrete designs with both traditional Asphaltic concrete and using reclaim…

Backcalculation of airport pavement moduli and thickness using the Lévy Ant Colony Optimization Algorithm

2016

Interpretation of NDTdata is crucial in any Airport Pavement Management System (APMS), in order to implement strategies to maintain airport pavementssince they allow to estimate their remaining life and related maintenance needs and activities. In this paper, the AntColony Optimization algorithmwasused for backcalculation of pavement moduli from surface deflection data. The algorithm’s performances are illustrated and improvement in prediction quality is demonstrated both in terms of goodness of fitness and computational effort. Moreover, it is proved that the proposed algorithm is also able to predict layer thicknesses, taking into account their variation too.

Factor Analysis of Passengers’ Satisfaction at “RIGA International Airport”

2015

Abstract The aim of the paper is to determine complex factors influencing passengers’ satisfaction at RIGA International Airport (Latvia). Theoretical evidence was examined and factor analysis was carried out to identify the main groups of factors affecting passengers’ satisfaction at the Airport. The findings of the study show that the most important five factors affecting it are: (1) availability of telecommunications, (2) effective way finding signs, (3) cleanliness of restrooms, (4) courtesy of staff and (5) availability of staff. The results based on this study will help airport managers in the Baltic Sea region to better serve their passengers through introduction of modern technologi…

Aircraft noise and premature birth

1978

Abstract Certain physiological effects suggest that there may be a relationship between premature birth and noise exposure. Vasoconstriction in the peripheric blood vessel system is one effect. Others would be augmentation of the adrenocorticotrophic hormone and a higher vegetative excitability during pregnancy. Animal experiments have demonstrated negative effects but there is little literature available as yet on the specific relationship between exposure to aircraft noise and negative effects on pregnancies. A study of this relationship was undertaken in an area near the airport at Dusseldorf, Germany. While no significant negative effects could be demonstrated, a tendency toward an incr…

Managing Greenhouse Gas Emissions for Airport Inventories: An Overview

2011

For some years now, problems relating to gas emissions that affect climate and result from human activities have assumed a global dimension of large importance. The climate is, indeed, influenced by the concentrations of some pollutants in the atmosphere; these pollutants trap the long wave radiation emitted by the Earth and alter the energy balance, causing an accentuation of the natural greenhouse effect. In this view an inventory of greenhouse gases can become the benchmark against which to measure the achievement of quantitative targets set at the political level in the fight against climate change. Contrary to a general inventory of emissions related with air quality objectives and loc…

REGIONAL AIRPORT: STUDY ON ECONOMIC AND SOCIAL PROFITABILITY

2010

Using Geomatics and GIS technologies, the aim of this study is the recovery of a regional economy focused on the areas that are marginalized and depressed, or with an emerging tourist industry, to reach explanatory variables of the airport impact on the regional economy. This analysis is conducted on the basis of geographical data and socio-economic features that characterized the area taken into account. Next to the main activities relating to international air traffic, which absorb large flows of traffic and offer primary and supplementary services, today airport is identified by their irreplaceable role in modern economic life, especially in the connections between places that, for geogr…

Fuzzy ServPerf model combined with ELECTRE III to comparatively evaluate service quality of international airports in Sicily

2015

In this paper a new approach was proposed so as to comparatively evaluate the quality of service alternatives. In particular, a fuzzy extension of the ServPerf service conceptual model was considered to estimate quality scores of fundamental service criteria, whereas the non-compensative multi-criteria decision-making ELECTRE III method was employed to point out the quality ranking of service alternatives on the basis of which the comparative service quality analysis was performed. In order to show the effectiveness of the proposed approach, an empirical study concerning service quality evaluation of the three international airports in Sicily (Italy) was conducted with detailed proposals fo…

Attraversamento trasversale Torre dell’Orsa - Aeroporto - Statale - Cinisi

2014

Lʼarea a sud-est dellʼaeroporto di Palermo è in rapida trasformazione: le espansioni edilizie di Cinisi e Villagrazia di Carini si sono saldate in una “campagna urbanizzata” continua, nel 2001 è stato inaugurato il tratto di metropolitana di Palermo che da Piraineto giunge a Punta Raisi con fermata intermedia “Tonnara Orsa”, la Società di gestione dellʼaeroporto Falcone-Borsellino (Gesap) ha previsto la realizzazione di un nuovo ingresso a sud dellʼaeroporto in corrispondenza del fuso racchiuso fra lʼautostrada A29 e la linea ferroviaria, a sud-ovest dello svincolo autostradale di Villagrazia di Carini, in località Bosco Tagliato, sorgerà un centro commerciale. I cambiamenti in atto e le ce…

Prediction of Airport Pavement Moduli by Machine Learning Methodology Using Non-destructive Field Testing Data Augmentation

2022

For the purpose of the Airport Pavement Management System (APMS), in order to optimize the maintenance strategies, it is fundamental monitoring the pavement conditions’ deterioration with time. In this way, the most damaged areas can be detected and intervention can be prioritized. The conventional approach consists in performing non-destructive tests by means of a Heavy Weight Deflectometer (HWD). This equipment allows the measurement of the pavement deflections induced by a defined impact load. This is a quite expensive and time-consuming procedure, therefore, the points to be investigated are usually limited to the center points of a very large mesh grid. Starting from the measured defle…
