L’articolo descrive i primi risultati di Assets4Rail, un progetto, finanziato con fondi UE, che vuole offrire un contributo al trasferimento modale a favore della ferrovia attraverso lo studio, l’adattamento e la sperimentazione delle più avanzate tecnologie di monitoraggio

Il lavoro propone un modello quantitativo per l’analisi della resilienza delle linee ferroviarie con particolare riferimento all’assicurazione della continuità del servizio mediante autobus. Per ogni tratta compresa tra due stazioni, si considera l’interruzione della circolazione

Summary-The European rail sector has a strong interest in innovations for monitoring the operational condition of a running vehicle. Many high technology systems can lead up to future rail systems relying on “intelligent vehicles”. This document describes the conceptual development of a monitoring system based on FEM calculations. The system uses signals from wheel-fitted transducers.

The present paper is a review on efficiency issues related to three important sectors of the transportation systems: railways, electrical vehicles, and marine. For the three sectors, the authors, in reference of their knowledge and research area, show the results of a wide literature analysis, in order to highlight which are the measures, in terms of technological solutions and management techniques, which are recently investigated and implemented, for improving the three transportation systems, from the point of view of efficiency.

The paper starts from the introduction of the safety management systems, as tools for the continuous improvement of rail safety performances and for the processes to identify the most effective measures to prevent accidents. The focus is on the level crossings, largely representing the most dangerous elements of the railway networks. The scope is the setup of an effective methodology for ranking the level crossings in view of the prioritization of actions to reduce the risks on intersections between rail and road.
