A Method of Designing Railway Signalling System Based on RAMS Indicators

چکیده
Shigeto HIRAGURI ȁSince the IEC published RAMS Standard in 2002 objective to railways, its importance and an impact of the standard to Japan have been conspicuous. On the contrary, new various train control systems based on information technology are under active development. Considering such situations, we assume that it is essential to establish a method to design railway-signalling systems, which has an excellent balance to the RAMS indicators at low costs. We propose the basic method to evaluate the performance of signalling system by a cost indicator based on the concept of RAMS, and confirmed that the method can evaluate systems appropriately considering of grade of line, circumstances and other factors.

Satellite-based localization technologies are strategic opportunities in railway applications because they offer new possibilities of service and have advantages that current technologies relying mainly on infrastructures deployed along tracks cannot equal. GNSS (Global Navigation Satellite Systems) can, in particular, offer localization services in ERTMS (European Rail Traffic Management Syste...
متن کاملAvailability assessment of railway signalling systems with uncertainty analysis using Statecharts
In this paper, we propose an original simulation approach to evaluate the availability of systems in the presence of state uncertainty which arises from incompleteness or imprecision of knowledge and data. This approach is based on a simulation method combining the belief functions theory and the Statecharts. Then we propose a Statechart model of a railway signalling system, European Rail Traff...
متن کاملAn Evaluation Method for Signalling System Based on Concept of Availability
In a railway signalling system, various safety technologies based on fail-safe concept have been developed and applied. They are having contributed to improve or enhance safety of railway traffic. In Japan, an importance of systematic approach to realise safety has been pointed out since 1970’s, and in recent years, a safety analysis which is based on FTA, FMEA and so on is performed commonly i...

This paper develops a methodology which allows the correlation between the cost which is required for the application of preventive and mitigation measures dealing with accidents which occur within a railway system and the improvement of the level of safety as a result from their implementation. The safety level is expressed either quantitatively, by the decrease of “fatality risk” indicator...
