Safety Measures

Abstract
Even though the general safety level of rail transport is quite satisfactory compared
to road transport, a problem still persists, that of level crossings (LCs). The
fact is that road users’ behavior plays a large part in accidents where most of
them do not occur following a failure of the railway system but are due to
individuals’ behavior. Knowing this, the Rail Optimization Safety Analysis
(ROSA) project intends to identify several safety measures through a cost benefit
analysis (CBA) in order to enhance the safety level at LCs on the French and
German railway systems. The choice of leading a CBA is not random. Indeed, it
allows comparisons between all the possible alternatives to aid the decision
makers to be able to invest in the most profitable safety measure. However, it is
very difficult to include all the effects of all the possible safety options. This is
why the results have to be interpreted with caution.
Keywords: cost benefit analysis, safety measure, railway, level crossing, LC.
1 Introduction
A cost benefit analysis (CBA) aspires to estimate the profitability of a project
from the whole community point of view by quantifying the willingness-to-pay
or the willingness-to-accept. The willingness-to-pay – or the willingness-toaccept
– is the stated amount that an individual is willing to pay – or to accept –
in compensation for a loss or a diminution of its utility. For instance, the
willingness-to-pay for human life informs society about the importance that the
governments grant for human life (e.g. Bellavance et al. [3]). In general, a CBA
takes place in four stages: i) the qualitative and quantitative assessment, ii) the
identification of all the possible effects for all the foreseen options and from the
point of view of different groups of concerned individuals, iii) the monetary
