Regional Air Transport in Europe: The Potential Role of the Civil Tiltrotor in Reducing Airside Congestion

The volume of air traffic worldwide is still in constant growth despite unfair events that sometimes occur. The demand for regional air transport is also increasing, thanks in part to the use of new vehicles purposely designed for short range flights which make this means of transport more attractive than in the past. This paper studies the possibility of using aircraft capable of vertical or short takeoff or landing (V/STOL), in particular the tiltrotor, in the regional air transport market and the impact on airport capacity that the use of this craft would have. With this in mind the advantages and disadvantages of using this vehicle are identified, as well as the changes to be made to the air transport system in order to exploit its full potential

Framing Stakeholder Involvement in Sustainable Port Planning

This paper presents a framework to encompass stakeholder involvement in port planning processes, by specifically focusing on long-term strategic plans aimed at sustainability and designed to satisfy the needs of a port community and its surroundings. A classification of the main port stakeholders is presented together with some traditional and non-conventional tools and methods that can be used to support the participation process, according to the degree of participation and the steps of the plan. This analysis takes its clue from the results of the EU PORTA project, aimed at setting a new system of guidelines to integrate regional planning and port management. Port authorities and local policy-makers can use the output of this analysis to understand how to deal with the complexity of multi-actor decisions in port planning. By duly taking into consideration stakeholders’ needs and concerns it will be easier to find the most shared solutions pursuing port sustainability

Il fenomeno delle dipendenze patologiche nella Provincia di Siracusa. Anno 2005. I Rapporto

Report on the state of legal and illegal substances use in the territory of Siracusa ProvinceIl Report analizza il fenomeno delle dipendenze nel territorio della Provincia di Siracusa. La descrizione del fenomeno si sviluppa intorno all\u27analisi degli indicatori individuati dall\u27Osservatorio Europeo delle Dipendenze di Lisbona (OEDT): 1-uso di sostanze nella popolazione generale (questo indicatore va a rilevare i comportamenti nei confronti di alcol e sostanze psicoattive da parte della popolazione generale); 2-prevalenza d\u27uso problematico delle sostanze psicoattive; 3-domanda di trattamento degli utilizzatori di sostanze; 4-mortalit? degli utilizzatori di sostanze; 5-malattie infettive. Altri due importanti indicatori che si stanno sviluppando, e che vengono qui illustrati, sono l\u27analisi delle Schede di Dimissione Ospedaliera (SDO) e gli indicatori relativi alle conseguenza sociali dell\u27uso di droghe (criminalit? droga correlata). Inoltre sono state applicate diverse metodologie standard di stima sia per quantificare la quota parte sconosciuta di utilizzatori di sostanze che non afferiscono ai servizi, sia per identificarne alcune caratteristiche

Analysis of road urban transport network capacity through a dynamic assignment model: validation of different measurement methods

Abstract Network capacity in a transportation system becomes an important measurement for transport planning and management because it addresses its capability to satisfy an efficient network traffic flow reducing the inefficiency of congestion phenomena. This work provides a discussion of road urban transport network capacity including existing definitions in literature and the validation of new measurement methods. The study explores some of the properties of network-wide traffic flow relationships in a large-scale complex urban street network using real-time simulated results obtained from a dynamic traffic assignment model, periodically updated by data from radar sensors through rolling horizon technics. The basic variables used in the methodology, such as network flows and speeds, are characterized using a network model calibrated in the urban area of Catania (Italy). For a comprehensive yet simple analysis, equations and graphs are utilized to resume the obtained results related to different days and several time intervals of the day. This procedure proved to be suitable to investigate the properties of network-level traffic flow relationships and concluding remarks include suggestions for further research in this highly promising area
