The report, titled Integrated network management digital twin: economic benefits analysis, shows the potential impact of such transport digital twins across the economy, environment and to the public.

The Department for Transport (DfT) alongside a consortium led by Arup, has published pioneering research on the economic benefits of digital twins for integrated transport network management

The research builds on the DfT Transport Research Innovation Board (TRIB) vision and roadmap to facilitate development of a national ecosystem of federated digital twins to improve the performance of multi-modal transport in the UK by 2035.

The report, titled Integrated network management digital twin: economic benefits analysis, shows the potential impact of such transport digital twins across the economy, environment and to the public. The report estimates the overall benefits of using integrated network management digital twins to provide benefits of approximately c£850 million (of present value in 2010 prices) across a ten-year period.

The launch of this research is expected to enable the sector to make the case for integrated transport digital twins, drive adoption, and improve transport efficiency through collaboration by:

• Linking operations across modes, for example, surface transport, maritime and air traffic management: Connected digital twins can enable seamless integration of various transport modes, optimising journeys across sea, road networks, active travel, bus, tram and rail systems, and air traffic, and between geographical boundaries. This integration can lead to improved situational awareness, reduced journey times, congestion and emissions, and enhanced overall transport efficiency.
  
• Enabling better responses to incidents or emergencies and improved cross-government response in emergency situations: Digital twins offer the potential for a comprehensive, real-time view of the transport network, allowing for rapid identification of incidents and swift, coordinated responses. This capability enhances safety, minimises disruptions and enables more effective collaboration between government agencies and emergency services during crises.
  
• Improving access to data: To enable data sharing and cooperation with adjacent sectors such as energy, and supporting the growth of innovations including AI.

Most of the benefits are expected to result from establishing integrated network management digital twins at large agglomerations and key corridors.

Aviation, Maritime and Security Minister Mike Kane said: “As we move towards an era of integrated sustainable transport, digital twinning is a powerful technology that can help us transform our networks, improve efficiency and make greener travel a reality.

“This report is an excellent example of how Government and industry can come together to deliver innovation and shows how valuable this technology could be to both the UK economy and the millions of people who rely on our transport networks every day.”

Ryan Hood, Digital Highways Leader at Arup, said: “This research underscores the potential of digital twins to optimise the performance of our transport networks. By harnessing data and technology to support a collaborative, multi-modal approach, we can create a safer, more efficient, integrated, and sustainable transport system. This technology not only promises significant economic benefits but also paves the way for a more resilient, predictive, and responsive system that can adapt to the evolving needs of our society.”
