This paper discusses improvements to the reliability of configuration data for ensuring the safety of railway signalling systems. The authors focused on human operations in the configuration data management in order to develop an error-proof system capable of preventing inadvertent operations. The first objective of this paper will be to analyse the error-proof system by assigning hazard levels to required items, by classifying required qualities into work phases, and by mapping the error-proofing principles onto error-proofing cases. The second objective is to develop metrics from the analysis of the error-proofing cases.
