Automated Railway Signs Detection. Preliminary Results
2019
Abstract Nowadays safety in railways is mostly achieved by automated system technologies such as ERTMS/ETCS. Nevertheless, on local railways (suburban and regional lines) several tasks still depend on the choices and actions of a human crew. With the aim to improve safety in such type of railways, this research proposes a system for the automatic detection and recognition of railway signs by means of the digital image processing technique. First field applications, carried out on the Italian railway network, show that the proposed system is very accurate (the percentage of correctly detected railway signs is about 97%), even at high train speeds.
La regolazione indipendente del settore ferroviario
2020
The wide regulatory power of the Independent Transport Authority on the railway sector. 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 beetw…

Kierunki modernizacji sieci kolejowej
2017
Opracowanie przedstawia kierunki modernizacji sieci kolejowej Polski w latach 2003-2017. Długość sieci kolejowej w kraju ulega zmniejszeniu. Zachodzi proces likwidacji linii i zawieszenia przewozów kolejowych. W kraju modernizowane są główne linie magistralne. Na modernizację składają się: wymiana torów, przebudowa trakcji elektrycznej i wprowadzenie nowoczesnych systemów sterowania ruchem i sygnalizacji (ECTS). Przebudowie ulęgają linie kolejowe o znaczeniu tranzytowym zaliczane do europejskiego układu połączeń kolejowych w ruchu pasażerskim (umowa AGC) i towarowym (umowa AGTC). Projekty modernizacji linii kolejowych są finansowane ze środków europejskich i krajowych. Główne źródła finanso…
LCA of Different Construction Choices for a Double-Track Railway Line for Sustainability Evaluations
2023
The international commitment to achieve carbon neutrality in the next few decades has oriented human activities towards the preservation of natural and non-renewable resources. In this context, a great research effort has been devoted to the search for sustainable solutions for the infrastructure construction sector, based on a thorough assessment of the environmental impact (EI). In this regards, Life Cycle Assessment (LCA) is considered one of the main components of Environmental Impact Assessment (EIA) and, for a comprehensive analysis, all the costs incurred by stakeholders during the useful life of the infrastructure should also be taken into account, applying the Life Cycle Cost (LCC)…
