A Study on Reliability and Safety Calculation of vital system in Railway Signalling System

신호시스템 요구사항 도출방안

Railway signalling system is required to be high safety against collision, derailment and collision at level crossing and to be high availability. The signalling system is usually divided into automatic train control, interlocking and centralized traffic control systems and each system must be high fail safe and availability. This study focused on reliability calculation of vital systems in train control system.
