A grid of material and immaterial laboratories for supporting the sustainability of transportation: the RESET project in Sicily
2015
Transportation is a crucial sector, to be suitably approached in order of getting human activities in more environmentally sustainable paths. In fact, in developing, as well in less developing, countries people and freights mobility are responsible of important amount of pollutant emissions and are cause of significant levels of energy consumptions. In this paper, a Sicilian regional project is presented, aiming at establishing an interconnected grid of material and immaterial laboratories. These laboratories, that are devoted at inducing more virtuous behaviors in the transportation policies, are constituted by equipment and software tools, mainly located in the region’s universities, acti…
La regolazione indipendente del settore ferroviario
2019
The National Independent Authority for Transport, imposed by European Law and established in Italy in 2013, is characterized by using wide powers of control, regulation and sanction, which cover all transport sectors. Regulatory competences seem in particular to interfere, in some areas, with the functions, also of political direction, of the State, Regional and Local Government, as well as the competences of the other administrative independent bodies such as the National Antitrust Authority or National Anti-Corruption Authority. This requires the provision of forms of coordination and cooperation beetwen those authorities, waiting for a clear actio finium regundorum by the national legisl…

A framework for defining a sustainability rating system for railway track-beds
2017
Railways perform a significant role in the transportation system and they have relevant environmental, economic and social impacts. They are currently engineered optimizing every singular aspect rather than considering a broader system for improving the sustainability of the overall infrastructure. Thus, it is necessary to promote an effort to define a global sustainability framework for conceiving the design, construction and management of railway infrastructure. The Sustainable Rating System (SRS) proposed in this paper is a tool under development that evaluates different alternatives of railway track-bed structure. Inspired by similar efforts in the field of road engineering such as Gree…
CHARACTERIZATION OF RUBBERIZED ASPHALT FOR RAILWAYS
2018
Rubberized asphalt mixtures are regarded as a solution for improving the strength of the rail-track section. The recycled rubber has become an enhancer of the modified bituminous mixtures. In this work, it has been shown as a sustainable improvement option in HMA mixes due to the elastic behavior exposed by the rubber particles. The impact of thermal susceptibility on the mechanical properties of the railway bituminous sub-ballast layer has served to the advanced measurement of the thermal cycles inside the rail track. Different simulations following the Kentrack and Kenpave software were employed to be effective with the best mix-design for railways. According to weather situation, reviewe…
In the rail sector, France needs to do more to connect its regional networks to the European network
2023
In an article for "Le Monde" newspaper, the legal expert Martial Pernet notes that, despite the texts in force, which he urges to be applied, efforts must be made to achieve the unification of the European rail network.
Dzelzceļa letālo traumu rašanās mehānismi un morfoloģija
2020
Ievads: Visā pasaulē viens no noteicošajiem faktoriem, spriežot par valsts labklājību, ir konkrētas pilsētas un valsts transporta sistēmas iespējas. Latvijā pēdējā laikā ātri attīstās un pilnveidojas sliežu transporta iespējas, līdz ar to dzelzceļa transportlīdzekļu radīto traumu risks var pieaugt. Latvijā dzelzceļā iegūtas traumas atrodas otrajā vietā aiz autotraumām transporta traumu grupā. Periodā no 01.01.2010 līdz 01.01.2019 Rīgās, Rīgas rajona, Ogres un Jūrmalas teritorijā tika reģīstrētas 94 uz dzelzceļā iegūtas traumas ar letālo iznākumu. Darba mērķi: Noteikt dzelzceļa letālo traumu ietekmējošos riska faktorus traumas gūšanas brīdī; noteikt dzimuma un vecuma grupu sadalījumu dzelzce…
Evaluation de l'impact d'un futur remblai de la ligne à Grande Vitesse Est Européenne sur le risque de gel dans le vignoble de Champagne
2002
In order to evaluate for the vineyard, the additional risk of freezing, which could be generated by a railway embankment of the High Speed Line (TGV «Paris-Strasbourg») a canvas cover of the future embankment (length 480 m, height 3 m maxi) was drawn up in the bottom of a wineyard slope. Measurements of Actinothermal Index (AI) Temperatures, at the height of the bud (at 50 cm of the surface) and measurements of of cold air windslopes, were carried out on a microclimatic scale. We recorded 19 points of measurements, without then with the presence of the canvas cover, for the nights characterized by a radiative cooling (wind £ 2m.s-2, clear sky) during spring 2001. The possible incidence of t…
Problematyka przejmowania infrastruktury kolejowej przez samorząd terytorialny – przykład województwa dolnośląskiego
2021
Regionalny kolejowy transport pasażerski w ostatnich latach dotknięty był zmianami w kontekście organizacji przewozów. Dotyczy to kwestii zarządzania oraz zasięgu obsługiwanej sieci kolejowej. Zauważalne są tendencje do reaktywacji połączeń oraz tworzenia nowych powiązań komunikacyjnych. Jest to związane zarówno z obsługą aglomeracji miejskich, jak i transportu regionalnego. Proces kreowania nowego układu komunikacji kolejowej oparty może być na reaktywacji nieczynnych tras albo budowie nowych połączeń. Procedura przejmowania niewykorzystywanych linii przez samorząd województwa jest elementem odtwarzania pierwotnego systemu kolejowego. Z jednej strony pozwala to na zachowanie infrastruktury…
Cost that is Directly Incurred as a Result of Operating the Train Service on the 1520 mm Rail with Primarily Freight Transportation
2016
AbstractUnder the Directive 2012/34/EU (21 November 2012) “the charges for … [rail] infrastructure … shall be set at the cost that is directly incurred as a result of operating the train service”. This charging rule is new for Baltic States’ railways, where due to the favorable geographic position a full cost application without detalization was possible. Although, a big number of relevant studies on the issue was made in EU, all of them covered only 1435mm railways with primarily passenger transportation. This study has been made in order to understand the impact of train operating on 1520mm rail infrastructure with primarily freight transportation.A gradual model of infrastructure chargin…
