Question to the Department for Transport:

To ask the Secretary of State for Transport, what action her department is taking to support the use of digital twin technologies across the UK's transport system.

Since the publication in 2023 of Transport Research and Innovation Board’s Transport Digital Twin Vision and Roadmap to 2035, DfT has established a dedicated team to lead a digital twins programme, aligned with the Transport AI Action Plan (2025).

This has already enabled the development of a diverse research programme, including the £46m TransiT research hub to decarbonise transport through digital twins; and a £5m programme to improve crisis response and resilience. These are providing the new tools and skills to ensure UK leadership in this key emerging technology.

To enable business case development and improve adoption, in 2024 DfT published its Economic Benefits Analysis for Integrated Transport Digital Twins, quantifying the key benefits this technology can bring to the UK economy, estimated to £1.85bn over the next decade.

Finally, DfT has directly supported industry innovation by funding innovative digital twin projects through the Transport Research Innovation Grants and the Freight Innovation Fund, to improve rail maintenance, traffic flow, urban resilience, better EV charging infrastructure and port operations.
