Safety Case Framework

CAM Testbed UK-approved best practice guidance for safety case development in the UK.

The Safety Case Framework: Guidance Edition provides direction for the safe testing and trialing of connected and automated mobility (CAM) in the UK. Authored by HORIBA MIRA, TRL and WMG, and compiled by Zenzic, it aims to help trialling organisations and reviewers save time and money, with a unified approach to safety case development.

The guidance sets out detailed safety requirements, offers an efficient process for developing best-practice risk management, and improves interoperability within and outside CAM Testbed UK. This reduces the need to duplicate risk management reporting, whilst maintaining exemplary safety standards.

There are two reports – one for trialling organisations creating safety cases, and another for reviewers of safety cases.

Background to the Safety Case Framework

 

Created in collaboration with CAM Testbed UK, it aims to strengthen testing processes, and improve public awareness of CAM testing in the UK.

Following the 2019 release of The Code of Practice for Automated Vehicle Trialling by the Department for Transport, Zenzic identified a requirement for a consistent approach across CAM Testbed UK, with safety requirements clearly set out in detail.

During 2019, an initial Safety Case Framework was developed, setting out top-level safety requirements for use across the CAM Testbed UK ecosystem. The initial framework formed the basis of the new BSI PAS 1881 standard. The framework was updated with the release of a second edition in 2020, which benefited from industry expertise and cross-sector contributions gained by BSI.

This 2021 Guidance is the third edition of the framework guidance, and has been based upon extensive research into existing methodologies. We held three industry workshops, attended by stakeholders with a wide range of perspectives, and were guided by an advisory group. It also draws upon the significant experience relating to trial safety management of the technical authors at HORIBA MIRA, TRL and WMG.
