The present work consists of two main parts. The first part (Chapter 2 and 3) deals with a literature survey where a short introduction is given for track geometry and track/vehicle interaction. After the introduction, a survey over the present standard in Europe and Japan is made. In particular the recent proposals for a common European Standard (CEN) and TSI (Technical Specification for Inter...

Wildlife mortality on roads has received considerable attention in the past years, allowing the collection of abundant data for a wide range of taxonomic groups. On the contrary, studies of wildlife mortality on railway tracks are scarce and have focused primarily on a few large mammals, such as moose and bears. Nevertheless, many species are found as victims of collisions with trains, although...

Railways play a crucial role in sustainable development of transport systems contributing to the economic growth every country. To maximize their potential, railways must monitor progress towards sustainability. Key performance indicators are tool for assessing sustainability railways. This study aims present comprehensive set railway and introduce new approach analysis. For this purpose, have ...

Well, someone can decide by themselves what they want to do and need to do but sometimes, that kind of person will need some electromagnetic compatibility in railways analysis and management references. People with open minded will always try to seek for the new things and information from many sources. On the contrary, people with closed mind will always think that they can do it by their prin...

We study variants of the vertex disjoint paths problem in planar graphs where paths have to be selected from a given set of paths. We study the problem as a decision, maximization, and routingin-rounds problem. Although all considered variants are NP-hard in planar graphs, restrictions on the location of the terminals, motivated by railway applications, lead to polynomially solvable cases for t...

This article presents industrial experience of applying the B formal method in the industry, on diverse application fields (railways, automotive, smartcard, etc.). If the added value of such an approach has been demonstrated over the year, using a formal method is not the panacea and requires some precautions when introduced in an industrial development cycle.
