Ansaldo STS Standardizes on Prover Certifier for Safety Verification of ERTMS Level 2 Systems Supplied in Sweden

STOCKHOLM and TOULOUSE, France, March 15, 2011 /PRNewswire/ --

- Following Successful Deployment for Urban Metro CBTC Systems, Ansaldo STS Orders Prover Certifier for Safety Verification of ERTMS Level 2 Interlocking Systems Supplied to the Swedish Transport Administration

Prover Technology, the world leader in Signaling Design Automation, today announced that Ansaldo STS has placed an order for using Prover Certifier for ERTMS Level 2 interlocking systems delivered to Trafikverket, the Swedish Transport Administration. Prover Certifier is the only software product on the market that enables automatic production of the complete safety evidence for CENELEC EN50128 SIL 4 certification based on formal verification. By using Prover Certifier, Ansaldo STS can replace traditional testing-based methods for checking safety; this reduces costs and provides 100 % coverage in safety verification of systems delivered.

As part of the order, Prover Technology will define a formal specification of Trafikverket's safety requirements. Based on this formal specification, Prover Certifier will be applied for safety verification of all ERTMS Level 2 interlocking systems connecting Boden and Haparanda ("Haparandabanan"). The formal safety verification will be performed against the software implementation of ASTS' SEI interlocking systems, in the C programming language. The formal specification of Trafikverket's safety requirements will be generic to enable reuse for any ERTMS level 2 interlocking systems delivered to Trafikverket.

Prover Certifier - increases quality and reduces costs

Prover Certifier is the only software product on the market that enables automatic production of complete safety evidence for CENELEC EN50128 SIL 4 certification based on formal verification. Formal verification is an analysis method based on mathematical proof. It is strongly recommended by safety standards organizations such as CENELEC, and several leading railway infrastructure managers require formal verification for safety assessment. The reason: formal verification increases safety and quality, and is more efficient than costly and time-consuming testing methods.

ERTMS - the future of European railway signaling

ERTMS is an initiative backed by the European Union to enhance cross-border interoperability and signaling procurement by creating a single Europe-wide standard for train control and command systems. ERTMS was designed to replace the many incompatible safety systems currently used by European railways, especially on high-speed lines.
