Abstract
Interoperability is a critical factor for cost cutting and to increase performance
in European railway exchanges. The European Railways Traffic Management
System (ERTMS), which is both a specification and a technological framework,
aimed at providing an answer to the above interoperability needs. Considering the
implementation of ERTMS in a particular national context, operating rules must
be compliant with the ERTMS specification, whereas the whole system has to
provide some safety properties. Moreover, the management of railway signalling
in ERTMS is based on \“not on board rules” pertaining to each country and not
on global rules. In consequence, it is difficult to evaluate the system in terms of
safety. Thus, one of the main purposes of this study is to supply methodological
tools for the evaluation of the global consistency between the specification and the
operating rules, with regard to safety. This issue is crucial and yet it has scarcely
been covered by scientific literature.
Keywords: ERTMS/ETCS, operating rules, functional requirements, safety
requirements, UML modeling, formal validation, B method.
