Architecture and related mechanisms. SAFEDMI - Safe Driver Machine Interface for ERTMS automatic train control. Deliverable D2.1, 2007.

Aim of this document is to provide a general architectural overview of the SAFEDMI system, together with an indication of its internal states, components and information exchanges. This document is to be considered as the foundations for the detailed architecture description given in D2.2, and should be read by those interested in understanding the role of the SAFEDMI system, its main characteristics, and the techniques and mechanisms that SAFEDMI uses to fulfil its goals, without going into a detailed description of components and software modules.
