Engineering a Safer World

Signaling Design Automation and Formal Verification to meet the Demand for the Railway of the Future

Speed, Safety and Savings

Railway infrastructure managers need new rail control systems to support increased traffic capacity. Existing legacy systems are replaced with new, digital rail control to reduce headway and conform to interoperability standards such as ERTMS and CBTC. This is where Prover plays a part. Prover provides software automation solutions that increase the capacity for delivering software for new and more complex digital train control, and meeting demand on improved safety for today’s more complex digital rail control.

Interlocking Design Automation

There is a need for a modern approach to signaling control for railway if infrastructure managers are going to keep up with the future demand. A modern approach need to handle flexibility and security at the same time.

A new process for how a signaling solution is developed and maintained must become standard practise. The efforts that is needed today for development and maintenance must be radically reduced.
