RAISO: RAilway Infrastructures and Signaling Ontology for Configuration Management, Verification and Validation

Signaling systems grant safety routes for railway transportation. Recently, the need of interoperable systems among different European countries increases in consequence of the increment of trades. This leads to data integration challenges. Railway operators provide nation-centric systems and tools. To tackle the complexity of this issue, an ontology-based railway model has been realized. Thus, this paper presents the development and the exploitation of model ontology which allows to formalize the layout of a railway network focusing on railway terminal (station) including the position of the track elements (signals, train detector etc.). Our investigation consisted in formalizing logical rules, which allow checking completeness, consistency of the model by automatically inferring the layout of the remaining installations (i.e., track circuit, signals and track sections) and the possible train routes through the network. A case study regarding the analysis of two different stations is also shown. The development has been produced in the context of RAISSS project with FESR from Europe to Region.
