Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment she has made of the progress of the Transport Research and Innovation Board's 2023 Transport Digital Twin Vision and Roadmap to 2035.

The Transport Research and Innovation Board provides regular oversight on the progress against the Transport Digital Twin Vision and Roadmap to 2035, as part of regular operations for all its areas of activity.

DfT has met all key government-owned milestones in digital twins, including working with the National Digital Twin Programme, enabling funding to research organisations, and providing a clear vision for the strategic case and benefits for digital twins in transport and adjacent sectors.

A key milestone was to provide clear evidence and guidelines on the benefits of digital twins, and DfT has published its Economic Benefit Analysis (2024) showing that this emerging technology can enable better integration of traffic management and deliver £1.85bn of benefits to the UK over a decade.

Additionally, DfT is working with the Advanced Manufacturing Research Centre to develop guidance on data interoperability and integration across transport.

The work is ongoing, and DfT committed in the recent Climate Adaptation Strategy for Transport (Dec 2025) to a long-term digital twin programme that aims to support network management, resilience planning and climate response.
