CLEARSY
Main CLEARSY’s know-how is the design and production of certified safe systems and software applications, through the use of formal B methods in urban and main-line railways sectors, for the design of driverless (GoA3) or unattended (GoA4) train operation systems. Moreover, CLEARSY translates the complex detail of European Interoperability’s ERTMS specifications into a suite of tools used by major companies and laboratories.
This year Clearsy is highlighting the following offerings:
Product description
