Our Vision is for climate resilient, net zero development of the transport system to be guided by systems analysis. When this vision is realised, decision-makers will have access to (and visualisation of) data that tells them how transport is performing against resilience, decarbonisation, and other objectives, now and in the future. We will deliver them systems models that will help to pinpoint vulnerabilities and quantify the risks of failure. This will enable them to perform 'what-if' analysis of proposed investments and to stress-test scenarios for the major uncertainties that will determine the performance of future transport systems, such as population growth, new materials and technologies and climate change. Our ambition is to deliver co-created research that plots viable pathways and solutions for delivering a resilient, net-zero transport system that works for people and communities by 2050. DARe will be the go-to Hub because we will engage widely and proactively, and provide the evidence, guidance and tools to decision-makers that will enable them to prioritise early interventions and investments. . Our research programme will take a system-of-systems led approach to transport which recognises and addresses the challenges at the three, distinct but critically interlinked, scales of national, regional and local. It will address the interwoven challenges of resilience and net zero, for both existing and new transport infrastructures, and identify and provide solutions for new vulnerabilities that may occur because of the net zero transition, including critical interdependencies with digital and power infrastructures. It will demonstrate the benefits and opportunities that come from reimagining and rethinking how our transport systems deliver mobility to both people and the goods and services our economy relies on, and will offer insight on how governance and policy can enable and drive these changes. We have shaped our research programme in consultation with our multiple civic partners in North East and North West England, Northumberland, Cambridgeshire & Heartland and Scotland as well as our strong cohort of additional partners. DARe will build on this by opening the partnership to all and proactively engage in a programme of co-creation events during the first nine months to jointly define scenarios and storylines leading us towards addressing the dual challenge of decarbonising our local regional and national transport infrastructures whilst increasing their resilience and adaptability in a context of climate change. The role and participation of the wider research community via the DARe Flexible Fund will be instrumental in delivering this. The DARe work programme comprises five integrated work packages (WPs), four focussed research activities plus a management WP. WP1 delivers the co-created transport futures storylines which shape the research activities of the hub and develops the storylines to stress-test solutions across the three spatial scales, contextualised by the systems-of-systems interactions between transport-power-digital critical infrastructures. WP2 provides a new, transferable open-source modelling framework that will be co-developed with and made available to the wider community as a legacy of DARe. WP3 will address the physical implications for infrastructure assets and how their climate-perturbed performance will impact whole-life management. WP4 will provide insights into the wider implications and real-world impacts of the storylines when considering the policy, socio-economic, behavioural and land use planning aspects of the hub. WP0 will be dedicated to hub management, governance and engagement.

Our vision for the TransiT Hub is to harness the transformative power of Digital Twinning, and associated digital technologies, to solve the most pressing problems of our age - the rapid and radical decarbonisation of transport , holistically, across all modes - Road, Rail, Air and Maritime, and at a national scale. The TransiT Hub will create a new interdisciplinary challenge-led national digital twinning capability to deliver scalable solutions of the integration and decarbonisation of transport, providing the thought leadership and coordination it requires. This is an urgent response to the climate emergency that will advance understanding of a complex and adaptive system, reducing uncertainty and risk for time-critical investments into sustainable, ethical and affordable decarbonisation. It will be centred on expert problem articulation of the challenges, ensuring planners, operators, and policy makers, will use this new capability to deliver national transformation and realise good climate, economic and social outcomes across the stakeholder community, as well as providing a blueprint for other sectors. While past approaches utilised small-scale, real-world trials and progressive scale-up, the need for rapid transition to a low-carbon economy, combined with the increasingly complex interaction between transport modes precludes this approach. This situation is currently holding back private and public investment and risking the UK's leadership in tackling climate change. Scalable digital twinning offers a way of quickly assessing and narrowing the decarbonisation options for the complex whole transport system. To? realise our vision we will co-create 9 Federated Transport Digital Twins across modes and passenger/freight types, culminating in a Federated Transport System of Systems (FTSoS). These FTDTs will use novel capabilities to support the design, development, delivery and operation of a reliable, secure, resilient, inclusive, decarbonised transport system at lowest cost and delivering best value. We will use an active and agile learning-by-doing approach, that can adjust to stakeholders, withstand scrutiny, and feedback new knowledge to the next iteration. The creation of the FTSoS will address a new paradigm of Whole System Digital Twinning - bringing together, coordinating and extending existing DTs in the sector, delivering capabilities currently unachievable within siloed mode specific DTs. Our approach addresses the challenges in interoperability, security and resilience, human-centred design, data management, policy delivery, and new business models, whilst leveraging existing DTs, and Cyber Physical Infrastructure, and growing national digital twinning expertise and capability. This will be shared with, and benefit from, wider national DT programmes, including NDTP and Energy System DT (ENSIGN), and other strategic investments such as DARE and the EPSRC Transport DT Network+, as well as linking with representative bodies and collaborations such as DfT's TRIB and the DT Hub. The Hub will bring together seven distinguished higher education institutions, UofG, HW, UoL, UoB, CU, UoC and UCL that reflect a careful balance across modelling transport modes and the cross cutting themes essential for federated digital twinning including human factors, cyber security,? connectivity, policy, economics, and digital twinning tools. Furthermore, significant in kind support has been committed by external partners across government and industry partners, including the Department for Transport and over 40 organisations across the transport sector. Our foundational work will be explored through application focused use cases developed with our industrial and academic partners providing practical anchoring of the research; knowledge transfer through bi-directional secondments and the generation of evidence to support robust policy
