ACRUDA - Assessment and Certification Rules for Digital Architectures
Overview
Background & policy context:
Urban and suburban railway networks are facing the need for improvements in cruise speed and reduced headways to enhance track capacity. Signalling systems are now widely computerised, but standardisation and a transition to communications-based solutions instead of hardware-based are pressing needs to improve operational efficiency.
Objectives:
ACRUDA aimed to develop a methodology for safety assessment of safety-critical digital architectures in the field of railway signalling in order to meet particular requirements of end-users and suppliers.
The primary objectives were the development of assessment criteria for safety architectures used in the guided public transport industry, and the specification of mutually recognised certification schemes. The secondary objectives were to ensure consistency with related EC projects and to establish a framework for standardisation of safety architectures.
