LO STATO PSICO - FISICO NEGLI STUDENTI UNIVERSITARI PENDOLARI

Lo stress è un insieme di modificazioni fisiologiche, cognitive, emotive e comportamentali di cui l’individuo ha esperienza nel momento in cui è richiesto un adattamento alle circostanze ambientali presenti: si configura pertanto come una reazione generale a situazioni specifiche e, non ha una connotazione positiva o negativa, svolgendo primariamente una funzione di tipo adattivo. Ciò che rende disfunzionale e “patologico” lo stress è il modo in cui l’individuo valuta la situazione con la quale si trova a rapportarsi: in questi casi si parla pertanto di distress, ovvero “stress negativo” (Selye, 1956). Gli stimoli e le situazioni che, valutate negativamente, determinano una reazione di dist…

Sustainable mobility: “exchange poles” between transport networks and urban structure

An intermodal hub can be defined as a place where transportation networks are organized to facilitate intermodality between different modes. Intermodal hubs should intrinsically have an urban dimension and be globally designed as “plug flows”, being interfaces between transport networks and territory, being an element to create “urbanity”. Intermodal hubs focus technical, social, urban, transport, service aspects and they play a multi-modal, multi-service, multioperator role. Several studies highlight the need to “measure the interdependence” among the various aspects of urban problems, avoiding too specific methodologies. The increasing congestion in urban centres and urban parking problem…

Sistemi di trasporto pubblico urbano via mare. Un modo per rilanciare il waterfront di Palermo

New sea transport terminals can be major people movers and main centres for various urban activities and functions, determining strong social output. The city of Palermo qualifies as a prominent research territory, due to its densely urbanized and populated waterfront areas, associated with a lack of transport infrastructures and efficient transit systems to meet the mobility demand of residents and commuters. A new waterfront arrangement can improve the city image and opens the way to new urban public transport systems by sea, like ferries and hydrofoils, as an alternative to the conventional land transit systems already affected by unavoidable congestion. Plans to link by sea different de…

The network of heliports as a necessary tool to develop rotorcraft services

The rotorcraft operations will grow as air taxi services and business trips and even as “commuter”, intercity and line services between urban centres and touristic or economic-industrial places of special value. But actually the rising public opposition to helicopter activities reduces the number of available heliports for private and corporate operators, as environmental limits of all type of allowed operations and of suitable sites to construct new infrastructures. So the growth of scheduled rotorcraft services (passengers and freights) has to be supported not only by advances in machine’s technologies, but also by an adequate and strategically distributed infrastructure network. This vis…

Evaluation of hand-arm vibrations during the use of portable olives harvesters

The use of portable shakers in olives harvesting is becoming increasingly, especially in Sicily, both to reduce the costs of production and to assure the oil quality. Nevertheless, it’s well known that the use of such tools may involve risk of exposure to hand-transmitted vibration. Such exposure to vibrations is a potential cause of muscular/skeletal pains in hand–arm system, and specific pathologies such as Vibration-Induced White Finger (VWF) and Carpal Tunnel Syndrome (CTS), Hand–Arm Vibration Syndrome (HAVS). The aim of this study was to assess the level of exposure to hand-arm vibration of the operators during the use of portable shakers for olives harvesting. Two different commonly u…

Noise risk assessment in a bottling line of a modern Sicilian winery

In wine industry, bottling is a phase of the production cycle characterized by high levels of noise mostly due to repeated collisions between the bottles. In Italy the Law Decree 81/2008 defined the requirements for assessing and managing noise risk, identifying a number of procedures to be adopted at different noise levels to limit workers exposure. This study aims at evaluating the equivalent and peak noise level inside the bottling plant area of a modern Sicilian winery. In particular, the influence of the working capacity (number of bottles produced per hour) on noise levels was evaluated. We considered three test conditions: T1 with working capacity of 4,000 bottles per hour, T2 with w…

La riqualificazione della viabilità costiera per la mobilità dolce: il caso di Palermo

The attractiveness and the availability of services offered in urban areas nearby the port terminals are conditioned by the improvement of the connection of different urban transport systems and by the enhancement of the accessibility. But they should be based on the overall improvement of urban mobility. The structural organization of the territory is favored by the presence of links, which realize an infrastructure system to the different levels of connection and accessibility. The interventions could include the requalification of the coastal strip, including the road network component. Attention should be given to the supply quality, the rationalization of a linear model based on the co…

Pedestrian Safety Indicators Study

Pedestrian mobility can be considered an important feature in a new model of town organization, being suitable for the newly urbanized areas as well as the old quarters and the outskirts, places where streets and squares, once devised for a pedestrian based mobility, were eventually overcame by an ever increasing motorized traffic. Enhancing pedestrian mobility could bring new life and activities into the old and historic parts of the town reviving their original identities. The last decade’s increase in the recourse to private cars requires improvements in pedestrian mobility quality. This can be achieved by building new infrastructures, limiting the use of private cars, improving public t…

GNSS/WEB-GIS heliport planning in a regional area for VTOL transport services

The role of the helicopter in airport planning and air traffic analysis is fundamental with re-gard to both the qualitative and quantitative increasing of the demand and the technical en-hancement of the aircrafts. This leads to infrastructural and organizational issues. Such a need finds a plausible solution in the implementation of a helicopter service and the creation of a heliport network linked to the airport, road and rail systems. Part of the issue of airport planning and design is the study of helicopters’ utilization for purposes other than commer-cial such as aerial work and civil protection. The helicopter is indeed essential in all those uses based on the capabilities that it ha…

The role of passenger modal shift nodes in the interaction between land use and transport system

In the last years we have observed a sub-urbanization process or 'sprawl' process (low density inhabitant models), caused by new economic and production conditions, by a free diffusion of new habitant models in territory, by new organization models of social relationships and by one-side power of road mode and in particular the private use. Commuters need to reach quickly own destinations and the traffic and parking problems in central areas increase mainly the importance of multi-modal displacements in an integrated transport system between public and private mode. Planner role should re-balance modal choice in favour to public transport and motivate passenger intermodality integrating the…

Interrelazioni fra pendolarismo, qualità dei servizi di trasporto e aspetti urbanistici

Il problema della mobilità quotidiana delle persone, dei loro spostamenti casa-lavoro, assume sempre più importanza sia dal punto di vista tecnico-organizzativo dei servizi di trasporto sia da quello socio-economico. In questo secondo aspetto il fenomeno della pendolarità lega in qualche maniera il mondo del lavoro al mondo familiare e domestico. Il tema si inserisce nel quadro delle trasformazioni che si manifestano principalmente negli agglomerati urbani, nelle grandi aree metropolitane, ma che fanno sentire i loro effetti anche su livelli territoriali più ampi. Gli aspetti tecnico-organizzativi sono oggi davanti a sistemi di trasporto tecnologicamente avanzati, sia nel trasporto su gomma…

The development of air traffic in Sicily

The aim of this work is to analyse the air traffic development that interested the airport system in Sicily, consisting of the airport of Palermo “Falcone –Borsellino”, the airport of Catania “Fontanarossa” and that one of Trapani-Birgi “Vincenzo Florio”. The analysis of the possible growth of air traffic volume and performance in Sicily was mainly suggested by the growing importance of the Mediterranean region like a new crossroad of the worldwide traffic on the East-West line. It gives a new chance for the development of this area that mustnÂ’t be loosed. Globalization and the migrant flows from South and East towards the Western Europe, makes of the southern Italy a strategic knot…

Eterogeneità delle preferenze e rilevanza degli indicatori psicometrici nelle decisioni di scelta modale: le prospettive per il trasporto delle merci. Un caso di studio.

Indicators for sustainable pedestrian mobility

Pedestrians walk everyday to satisfy their basic necessities. They need an environment that reflects their requirements and expectations, in other words "liveable" as much as possible. So we should offer tools that could allow a complete and clear evaluation of the existing walking environment, taking into account both pedestrian requirements and urban environment schemes. To measure pedestrian mobility performance we usually use indicators, which measure performances and grant a quick estimation of progress. Indicators are universally acknowledged synthetic and standard parameters that should help policy makers gauge whether things are going in the right direction or not. They should be ou…

Infrastructure, Tariff and Legal Action: How to Achieve a Climate-Friendly Transport System

Transportation absorbs about 70% of oil consumption in EU countries. The fuels that burn in the field of transport are composed of 96% of oil. Energy efficiency of road and air traffic must also be improved. But transport environmental impacts reductions should be made necessarily through a transfer of traffic from the car, lorries and aircraft to train, ship, and non motorized two-wheelers into the EU cities. In fact the former are large producers of greenhouse gases, while the latter are more environmentally friendly means of transport in climate. Reaching an annual increase of 1% of the modal split in favour of more sustainable means of transport on the environment must be set as a goal …

IL RUOLO DELLA QUALITÀ PERCEPITA DEI PERCORSI PEDONALI NELLA SCELTA DEL TRASPORTO PUBBLICO

Il fenomeno del pendolarismo oggigiorno coinvolge ampie fasce della popolazione, manifestandosi attraverso spostamenti sistematici, spesso quotidiani, dal proprio luogo di residenza verso altra destinazione, per motivi di studio o di lavoro. La definizione di spostamento pendolare prescinde dalla distanza percorsa o dal tempo di viaggio. Tipicamente, i pendolari si spostano tra differenti aree di regioni metropolitane, seguendo percorsi multimodali, costituiti anche da itinerari di “mobilità dolce” (pedonale o ciclabile). La mancanza di una cultura della pianificazione urbanistica, la diffusione sul territorio delle funzioni residenziali e l’accentramento delle attività produttive e commerc…

Taste heterogeneity and latent preferences in the choice behaviour of freight transport operators

In this paper we show that individual attitudes of road carriers and their latent preferences toward specific freight service attributes do play a role in determining their mode choices. Specifically, we contribute to the empirical literature on freight agents' mode choice by exploring the role of the "perceived importance" of the most relevant service dimensions in determining the attractiveness of two alternatives to "all-road" transport: logistics terminals and road-sea intermodal services. This is carried out through a revealed/stated preference experiment and a mixture of logit framework. Our results support the hypothesis that operators' attitudes towards time, punctuality and risk of…

The influence of Advanced Traveller Information Systems (ATIS) on public transport demand

A comparative analysis between helicopter and seaplane for passenger transport.

Purpose This study aims to develop a methodology to compare the feasibility of helicopter and seaplane regular transport of passengers towards destinations across a remote regional tourist context, where a lack of road and rail infrastructure make these alternative forms of air transport competitive. Design/methodology/approach The authors use a modal split model identifying the quota of passengers that potentially could utilize these two types of services, determined on the basis of previous studies on air transport demand. A technical analysis regarding transport supply is performed to identify the predominant features that should characterize helicopter/seaplane performances. An optimiza…

The accessibility of public urban spaces: walkability and ergonomic aspects

Pedestrians can be ergonomically considered as workers into the socio-technical system of public urban space. Pedestrian targets can be defined as operations: the accessibility to a place characterized by services, commercial activities, enjoyment of leisure. Public space is a "universal" tool (differently from the ergonomic one), but it serves different user categories and enables different targets (movement, parking, social integration, etc..). The organization of public space should basically allow to perform users’ activities, but it has often been divided into a spatial and thematic compartments. From the twentieth century it was subservient to the dominion of the car, which strongly i…

Gli itinerari turistici in ambito urbano tra accessibilità e informazione

Palermo è una delle città, culturalmente ed economicamente, più importanti dell’intera area del Mediterraneo. Ricca di un notevole patrimonio architettonico e archeologico, è caratterizzata da un elevato potenziale turistico a cui non corrisponde un’adeguata rete di collegamenti e di servizi di trasporto multimodali. Oggi i centri urbani, dalle metropoli ai borghi, rappresentano uno degli anelli più importanti del sistema di offerta turistica, perché sono i luoghi in cui il turista, occasionale e/o di lunga permanenza, si trova di fronte a beni, servizi, cultura ed esperienze, diventandone consumatore. È proprio in questo processo che il visitatore ha necessità di percepire servizi di quali…

A Data Envelopment Analysis methodology for the efficiency’s evaluation of a group of transport heliports offering scheduled flights

Heliports are relatively small infrastructures able to serve medium volumes of regional traffic in poor accessible areas or in zones just located to the next proximity, or in some cases inside, urban areas. The spaces required for the movement of heli-copters on the airsides of these infrastructures are far smaller than those required for airplanes. This characteristics derives from the great flexibility of the VTOL in mov-ing in tight spaces. On the other hand, the need for land saving especially in those filled areas within the major cities requires infrastructures large no more than a block. The use of the helicopter as a mean of transport to serve the traffic between cities and airports…

The interaction between rail stations and urban area in medium-sized towns. A case study for Trapani.

Regional passenger transport. A comparison analysis between helicopter and seaplane

Heliports and seaplane bases are relatively small infrastructures able to serve medium or low volumes of regional traffic in poor accessible areas or in zones just located to the next proximity of the urban areas. The spatial extension of the airside is directly connected with the costs of the infrastructure and it is primarily determinate by the type of aircraft that uses the infrastructure and secondarily by the design expected traffic. The helicopter infrastructure is far smaller than that required for airplanes and seaplanes, since the first doesn’t suffers the lateral wind on the approach and landing direction. On the other hand, the rotorcraft suffers operative costs largely high than…

Future trends for the civil rotorcraft

In response to public needs about the use of air transport to connect high congested or remote areas where airports are not present, rotorcraft (or seaplanes), represents the only available alternative. Today the helicopter industry focuses its tasks in the maximization of profit, building multirole aircrafts that can be adapted to all types of use: from the military to the civilian one, from HEMS and SAR to the Off Shore one. On the other hand the rotorcraft enterprises are small companies, often characterized by a limited budget and weak demand services. Often, analyzing rotorcraft civil transportation, companies are forced to perform on-demand services, as the operating costs of the airc…

Vertical take-off and landing air transport to provide tourist mobility.

Abstract This paper examines helicopter transfer services to reach attractive and not very accessible tourist areas, taking Sicily and its minor islands, in the South of Italy, as a case study. We investigate the viability of helicopter scheduled services for tourists moving from/to airports or doing one day tours to visit far away places. The mode choice of tourists is simulated using random utility models employing stated preference data. Heli-shuttle service is planned in terms of fleet size, frequency, fare and location pattern of heliports. The paper also analyses how a public subsidy reducing fares might change the set of feasible connections.

Latent Class Model to Test the Preferences Heterogeneity in the Perceived Information by Public Transport Users

The aim of analysis is to understand as not reliable information influence the user behaviour and how much disincentive the public transport use. For this purpose, a Stated Preference Survey has been carried out in order to know the preferences of public transport users related to information needs and uncertainty on the information provided by Advanced Traveller Information System (ATIS). The perceived uncertainty is defined as the information accuracy. In our study, it was considered the difference between forecasted or scheduled waiting time at the bus stop and/or metro station provided by ATIS, and experienced one by user, to catch the bus and/or metro respectively. A questionnaire has …

The quality of life in urban areas: mobility and social exclusion.

The social exclusion is described as the process that progressively marginalizes individuals, groups and communities from the labor market and from the access to basic services for health, education and transport. The ability to access to (in a spatial sense of the term) the job, the education, the health services and other services is a key factor of social inclusion. Accessibility is important, not only because facilitates the achievement of a regular job, stable and profitable, but also because it is part of the social capital, the latter ensures the social relationships that form a safety margin of the poor people. Accessibility is increasingly recognized as a key element of a sustainab…

Road safety for the elder pedestrian in urban contexts - L'insicurezza per i pedoni anziani in ambito urbano

Accidents involving elderly pedestrians are an important statistics on accidents due to vehicular traffic. So many researches investigated loss of safety of the elderly. The transition from work to quiescence period changes individuals’ lives and their concept of mobility, but car use is still prevalent during some years. Then the elderly significantly change their way of moving, preferring to walking. Over the years they become more and more fragile and they see the decline of their physical, sensory and cognitive faculties, so their safety has to lead urban Administrations to find practical solutions to improve movement and comfort of these urban users. This study aims to explore possible…

La puntualità dei collegamenti ferroviari nell'area metropolitana di Palermo

Helicopter operations: the environmental impact and ground facilities. Procedures and operational standards for the system’s acceptance.

The link between the heliports, environmental quality and safety is an important challenge in the field of helicopter transport. This challenge is especially crucial when the helicopter operations are carried out on densely urbanized areas. Often these areas have significant constraints and obstacles, particularly in terms of noise pollution. These constraints make the approach/takeoff maneuvers very complicated. The theme of the environmental sustainability of the rotorcraft is strongly felt in many countries. The production of noise is subjected to numerous rules and procedures, which tend to improve the acceptability of the helicopter by residents in neighboring areas to verti/heliports.…

Localizzazione ottimale degli stalli per il parcheggio delle biciclette: il caso studio della città di Palermo - Optimal location for bike parking lots: the case study of the old town in Palermo

The lack of parking spaces for bicycles is one of the main issues that many cities face. A proper planning of a bike station network is necessary in order to optimize the whole urban system and the transport supply. In this work a step-by-step analysis is proposed to find the best location for the bicycle lots in the old town of Palermo. The optimization method includes the use of both a Set Covering Model and a Maximum Coverage Location Problem. The dataset for the simulations was collected by direct and indirect surveys on the population and implemented into Open source GIS software. In particular, data on the destinations, times and distances covered by the bicycles’ users were included.…
