Abstract

As safety-related regulations for signaling systems are standardized to IEC 61508/62278/62425, and others at the international level, safety activities and its assessment are required to be performed. And also there is the need to develop technologies for safety improvement to secure safety signaling systems in terms of technologies for safety activities on each life-cycle. In this paper we have developed the safety activity processes and technologies each steps of proposed processes respectively for railway signaling systems. And the proposed process and technologies are applied to the safety activities for mock-up signaling systems.
