Formal Methods for Railway Disasters Prevention
Résumé
Due to the increasing complexity of railway signalling systems, the design of those systems is more difficult and the demonstration of their safety can be extremely tedious. In this article, the verification and validation of railway signalling systems is investigated. We explain how railway signalling functions are designed, we show how they can be mathematically modelled using formal methods and we discuss some ways to use formal methods mechanisms to design, verify signalling systems and to prove the validity of their safety properties.
