This document describes how ERTMS and non-ERTMS information will be arranged and displayed from an ergonomic point of view. More specifically, it covers information that is out of the scope of ERA_ERTMS_015560. This document describes more ergonomic details than currently provided by the ERTMS/GSM-R specifications.
This document defines the ergonomics for the Driver-Machine Interface (DMI) for the following applications:
- stand-alone ERTMS/GSM-R Train Radio Systems;
- non-ERTMS/ETCS Train Control Systems;
- other technical systems currently provided on the rolling stock.
The ergonomics covers:
- the general arrangements (dialogue structure, sequences, layout philosophy, colour philosophy),
- the symbols,
- the audible information,
- the data entry arrangements.
This document is limited to ergonomic considerations and does not define the technology to be used for the implementation but it does give guidelines about how to implement the requirements using different technology types (soft keys, touch screen device, LCD, electromechanical instruments, indicator lamps, etc.).
This document is applicable to all trains fitted with the ERTMS/ETCS and also to trains fitted with train radio (GSM-R) DMI.
The scope of this document is to define ergonomic principles for the interface between the driver and the above listed applications.
TDD is out of scope of the CLC/TS 50459 series.
For human factor items, such as display of information, display location, viewing angles and organization of the screens, see EN 16186 series.
