초록

It is demanded to produce the safety evidence documents in other to approval safety characteristic of railway signaling system which stands is included, it is demanding from IEC 62425 standards. Also it is express clearly that safety assessment if signaling system has to be verification of these safety evidence documents. This Safety Case has the results of safety activity through system life-cycle, such as hazard lists, hazard identification and analysis, risk assessment and countermeasure, verification and test results. Consequently, first of all, the analysis and verification of these Safety Case documents has to be accomplished to approval and acceptance of signaling system safety. And also if the safety assessor was want, it is able to be experimental test auditory which is, arbitrary faults injection test, to above described documents verification. In this paper, the contents and architecture of Safety Case are presented as first steps of safety assessment technology establishment for railway signaling system.
