Building formal competence for safer and smarter railway signaling<\/h4><\/div><\/div><\/div>What did we do in forms of technical solution?<\/h4><\/div><\/div><\/div>Short intro of the project<\/strong>
\n<\/strong>The project focuses on converting Trafikverket\u2019s signaling regulations (TRVINFRA) into formal requirements to enable digitalization and automation within railway signaling. It is a continuation of earlier work where Prover demonstrated how signaling rules could be expressed in formal logic and verified using model-based tools.<\/p>\nWhat was the purpose?<\/strong>
\nThe aim is twofold:<\/p>\n\n- To translate Trafikverket\u2019s signaling principles into formal requirements, ensuring that the regulatory framework is unambiguous, structured, and ready for use in design and verification workflows.<\/li>\n
- To build Trafikverket\u2019s internal competence in formal methods, so the organization can manage, maintain, and extend formalized requirements in the future.<\/li>\n<\/ol>\n
How did we resolve the issue?<\/strong>
\nProver contributed expertise in formal methods and tool configuration, guiding Trafikverket in structuring and formalizing requirements using the open HLL language. Workshops and training were held to teach formalization techniques, and example requirements were implemented and validated using Prover iLock. A process for managing and maintaining formal requirements was established, including a governance and documentation plan for future use.<\/p>\nWhat was the result of the project?<\/strong>
\nThe project contributes directly to Trafikverket\u2019s long-term digitalization goals by introducing a methodology that increases safety, reduces ambiguity in signaling regulations, and improves efficiency in design and verification processes. The collaboration between Prover and Trafikverket also establishes a foundation for future projects involving automated signal verification.<\/p>\n<\/div><\/div><\/div>- <\/i><\/span>\n
