In relation to international railway transport, majorty of current international railway safety regulations, standards and safety indicators are based on European Union. As a result, railway operation characteristics of Asian countries including Korea are not reflected. In order to international railway operation in Korea, objective indicators of domestic railway safety and analysis of domestic characteristics are essential. To this end, this study performed a comparison by converting domestic railroad safety indexes according to the railroad safety index guideline of international organizations, and examined ways to reflect domestic railway safety characteristics. Through this, the preliminary review of various railway safety indicators for future international rail connections was suggested, and suggestions were made to reflect the items that need to be supplemented and the characteristics of Korea.
