Abstract

Every year, more than 400 people are killed in over 1200 accidents at road-rail level crossings in the European Union. Together with tunnels and specific road black spots, level crossings (LC) have been identified as being a particular weak point in road infrastructure, seriously jeopardizing road safety. Safety at LC is a single part of a wider picture of transport safety within the whole transport system. For many years, governments as well as the rail industry and road organizations have been implementing a variety of countermeasures to improve railway level crossing safety. Despite the fact that these actions are substantial and have resulted in a continuing decrease in the number and the severity of level crossing accidents, LC are still identified as being a weak point in road infrastructure, seriously jeopardizing road safety. This constitutes a difficult problem to be solved by Rail companies. Indeed, they cannot control the actions of road vehicle drivers and pedestrians at level crossings.

This special issue focuses on safety at level crossings and provides a wide picture on the development of new approaches and technologies to improve safety at level crossings. The papers presented in this special edition reflect the scientific multidisciplinary topic of level crossing. These contributions can be classified into three categories: Appraisal, modeling and technology.

A. Janota’s paper discusses the problem of safety of Slovak level crossings, seen through the statistical data, and explains distinctive features identified on the base of comparison with level crossings operated in other EU countries. It deals with a knowledge-based approach applied to diagnosis of electronic/computer-based level crossing installations.

A. Berrado’s paper introduces a risk management framework that allows to understand and to assess the risks associated with a given level crossing. The suggested framework involves several activities, including, hazard identification, risk analysis, evaluation, treatment, and control. It illustrates how it can be systematically applied to mitigate risk at a given Moroccan level crossing.increasing lateral visibility early enough and with advance warning signs.

Above all, we hope that this selection of papers demonstrates the degree of science, engineering and N. Fakhfakh’s paper on “A video-based object detection system” aims to improving safety at LC. The contribution provides a possible technological solution to reduce the number of accidents at level crossings and discuss the effectiveness of the use of video sensing for 3D object detection.

F. Deffossez’s paper completes this approach by developing a formal methodology to analyze the safety of discrete time process that can be applied to level crossings.

Safety at level crossings is also a major concern at Finnish railways and Dr. Kallberg’s paper deals with the sight distance requirements for Finnish LC. This is particularly critical since less than a quarter of all level crossings are equipped with active warning devices, not only barriers but also warning lights and bells. Especially at passive level crossings, it is entirely up to the road user to know whether it is safe or not to cross the railway. The author discusses the formulation of safety guidelines for Finnish level crossings, conducted at VTT “Technical Research Centre” for the Finnish Rail Administration.

Dr. Kallber’s paper on Safety audits of Finnish level crossings for 10 years presents a number of recommendations for safety measures to improve safety.
