Abstract (in Japanese) (See Japanese page) 
(in English) A safety confirmation train control system, being developed by RTRI, aims to reduce labor requirements for train operations, simplify wayside facilities, and enable more flexible train operations. A distinctive feature of the system is that safety is ensured through control logic designed under the assumption that communication interruptions may occur when public communication networks are used. In this paper, a safety assessment of the proposed system was conducted using Fault Tree (FT) analysis, and countermeasures for ensuring safety against the identified hazardous events were systematically examined.
