## Summary

The Department for Transport commissioned research services on the safety of theoretical Automated Driving Systems (ADS) and Driver Control Assistance Systems (DCAS). The work compares these systems with the UNECE ADS regulation under development and UN Regulation No. 171 on DCAS, identifying possible gaps, missing requirements and areas for future amendments. It is a specialist automotive safety, regulatory and systems-analysis assignment rather than vehicle manufacture or deployment. Delivery may cover the United Kingdom, the Channel Islands, the Isle of Man, Europe, British Overseas Territories and the rest of the world. The requirement is classified as research services and is identified as suitable for small and medium-sized enterprises.

The procurement has been completed and awarded to WSP UK Limited. The award was made on 2 September 2026 for £91,395.60 including the stated GBP currency. The contract runs from 7 September 2026 to 6 March 2027. It was let as a selective call-off from a dynamic purchasing system, with submissions closing on 12 August 2026 at 12:00 BST. The Department for Transport evaluated the requirement as a services procurement focused on comparative regulatory and safety analysis of ADS and DCAS. The awarded supplier is WSP UK Limited, and the award is active. This is a single identified requirement rather than a procurement divided into separate lots.

This award indicates demand from the Department for Transport for independent, technically rigorous analysis of automated-driving safety and regulation. A credible future competitor would need expertise in systems-theoretic process analysis, automated-driving systems, driver-assistance technologies and vehicle safety assurance. It would also need to interpret emerging UNECE requirements and existing international regulations, identify regulatory gaps, and turn that analysis into practical recommendations for amendments or further requirements. Experience comparing theoretical system designs against formal regulatory frameworks would be particularly relevant. The route used was a dynamic purchasing system call-off, so suppliers seeking similar work should be capable of meeting that system’s qualification requirements and delivering specialist research as a standalone consultancy assignment. The buyer’s stated suitability for SMEs suggests a focused specialist firm could be well placed.

## Notice

This project will analyse the safety considerations for a theoretical Automated Driving System (ADS) and Driver Control Assistance System (DCAS) in comparison to the UNECE ADS regulation under development and UNR 171 on DCAS, identifying potential areas for future amendments to close off any possible gaps or missing requirements.
