초록

Recent advances in computer technology have brought more dependence on software to train control systems. Hence, the safety assurance of the vital software running on the railway system is very critical task and yet, not many works have been done. While much efforts have been reported to improve the safety of electronic hardware, not so much systematic approaches to evaluate the safety of software, especially for the vital software running on board train controllers. In this paper, we propose the guide line of actually applicable software safety assessment in train control systems. And we demonstrate the results of developing a new tool based on web system version for software assessment management.
