New technologies are having an impact on mobility systems and the railway industry. However, standards impose strict limits on technological solutions because they are still based solely on known and proven designs.
Conventional safety assessment methods are therefore no longer entirely appropriate.
Safety demonstrations based on limited innovations introduced into already accepted designs (e.g. using ‘globally at least equivalent’ GAME methods) only apply to a few specific cases. New methods must be found to effectively assess the safety of systems using, for example, decentralised computing, artificial intelligence, sensor fusion and intelligent detection.
Safety must not be sacrificed in the name of innovation, at the risk of introducing dangerous innovative systems.
The objective of the UIC’s ‘New Methods for Safety Demonstrations’ (NMSD) project is to examine, qualify and select potential future methods for performing safety demonstrations in a context of rapidly evolving technologies.
CLEARSY is partnering with the UIC and its Operations & Safety department to carry out this research. The project began in the last quarter of 2022 and lasted three years.
Here is one of the presentations given in Beijing in 2025: 12WCHSR_NMSD_FH_final_20
