The proposed framework includes modelling of interfaces between risk analysis, risk evaluation and scenario’s representing flows of safety information of the European Railway Traffic Management System (ERTMS). In this study, we propose a functional framework combining safety data generation, data processing and structuring, definition of interactions and finally, the creation of customized representations in order to predict, explain, and control risks. Through literature review and ERTMS applicability, we develop a safety architecture overview framework. The comprehensive overview of the safety architecture can illustrate the main interactions between government, regulations, company management,
technical and operational management, physical process and activities, and environment. Explicit representation delivers insight, stimulates striving for completeness, and leads to consistency of the safety analyses.
