Supersession

This PAS supersedes PAS 1881:2020, which is withdrawn.

Relationship with other publications

PAS 1881 has been developed as part of a wider programme sponsored by CCAV in conjunction with the Department for Transport (DfT), Innovate UK and Zenzic to develop a suite of standardization products to promote the safe testing and deployment of automated vehicles in the UK and inform wider international standardization activity.

This PAS is intended to be read in conjunction with:

• standards and guidance on functional safety, cybersecurity, safety of the intended function and other PAS Standards, including:
- • PAS 1880 , Guidelines for developing and assessing control systems for automated vehicles
- • PAS 1882 , Data collection and management for automated vehicle trials for the purpose of incident investigation – Specification
- • PAS 1883 , Operational Design Domain (ODD) taxonomy for an automated driving system (ADS) – Specification
- • PAS 1884 , Safety operators in automated vehicle testing and trialling – Guide; and
- • PAS 1885 , The fundamental principles of automotive cyber security – Specification;
• where applicable to the trial, safety and stakeholder requirements:
- • the DfT’s Code of practice: Automated vehicle trialling[1];
- • Transport for London’s (TfL) Connected and autonomous vehicles: Guidance for London trials[2]; and
- • National Highway’s GG104: Requirements for safety risk assessment[3]; and
• existing legislation applicable to the use of vehicles on public roads and private land in the UK.
