Abstract

Renewals and especially enhancements of rail signalling and control systems are increasingly including a strong programme of human factors integration. One contribution to the human factors work that is required is work analysis - the understanding of what tasks and functions exist in current work systems, the artefacts (controls and displays used) and the strategies employed by skilled operators. One increasingly common approach to such work systems analysis is cognitive work analysis (CWA), used to develop understanding of a work domain and tasks in a structured fashion and as a basis for new design recommendations. The purpose of this paper is to explain, for an engineering and systems developer audience, the basis for and use of CWA. This is done in the context of rail electrical control rooms and especially the use made of various information display elements including alarms.
