Railway Collision Risk Analysis Due To Obstacles
Author(s)
A. Fernández & B. Vitoriano
Abstract
In the following article, the risk of a train suffering an accident by collision is
analysed in conjunction with an unexpected obstacle on the track. This study is
applied to high velocity railways, although this could be reflected towards any
other lines. Various measures associated with the risk of accident, can be defined
accordingly: the probability of being engaged in an accident, the time on risk and
the critical velocity. Subsequently, the elements which alter the previous
measures are analysed. These elements are related to rolling stock, to the railway
infrastructure and the density of the traffic. A model is proposed to obtain the
appropriate risk measures of a configuration of these elements, and to compare
and evaluate the impact of different configurations. This model is applied to the
case study b
