Areas of research interest 2023

Updated 13 April 2023

Foreword by DfT’s Chief Scientific Adviser and Chief Analyst

Welcome to this 2023 update of DfT’s Areas of Research Interest (ARI), building on the positive reception we received from our previous ARI publications.

DfT is a strongly evidence-based department, bringing in expertise at all levels. This expertise is delivered through many different mechanisms, including project steering boards to help steer individual pieces of work, delivery of specific projects and advice through directly commissioned work or competitions, or through strategic boards such as our Science Advisory Council or our Joint Analysis Development Panel.

This document covers science and analysis, which are core to DfT decision-making, helping ensure transport policies and investments meet DfT’s strategic priorities, such as growing the economy and reducing environmental impacts.

DfT has 5 strategic priorities.

1. Grow and level up the economy, ensuring transport fulfils its growth potential though improving connectivity across the United Kingdom and enhancing the transport network, on time and on budget.
2. Improve transport for the user, building confidence in the transport network and improving transport users’ experience, ensuring that the network is safe, reliable, and inclusive.
3. Reduce environmental impacts, tackling climate change, improving air quality, biodiversity and ensuring the transport system adapts to be resilient to the effects of climate change.
4. Increase our global impacts, boosting our influence and maximising trade by having an innovative, outward-facing approach.
5. Be an excellent department, to ensure DfT is a department that continuously improves its delivery, and where people feel well supported, are able to reach their potential, learn and enjoy working.

Scientific evidence and advice are essential to achieving these priorities, enabling us to deliver our programme of work effectively, efficiently, and at pace needed to respond to challenges along the way.

This updated ARI sets out our strategic evidence and research needs for the medium- to long-term by listing the priority research questions against each of our strategic priorities. This will support our ambition (under ‘be an excellent department’) for all parts of DfT to work with the wider transport research community to help meet these ambitions and successfully tackle the challenges and opportunities ahead.

This document describes both the ‘bottom up’ specific questions which have emerged directly from policy teams, and some co-designed higher level strategic questions which group these issues, aiming to influence larger, cross-cutting initiatives.

This document is the tool by which we will communicate and engage with the transport (and wider) research community. We continue to invite the UK’s research community to actively engage with us and align your research programmes with the priority areas outlined in this document.

Purpose

This updated Areas of Research Interest (ARI) builds upon DfT’s 2021 ARI to provide an updated account of our priority research and evidence needs. The document is not intended to be a list of projects or invitations for contracts, but a list of research themes and priorities for DfT, in particular those with a medium- to long-term focus.

The purpose of this document is to communicate a summary of DfT’s research and evidence needs with researchers outside the department, providing transparency and clarity and inviting collaboration. This will enable:

• external research organisations to understand and align with DfT’s priorities, maximising the opportunity for research impact and encouraging research capacity to grow in priority areas of interest
• an increase in the number, disciplinary background, and diversity of DfT’s R&D delivery partners
• more partnerships with other funders and research programmes, enabling research to be delivered more collaboratively and efficiently, working together towards shared goals
• a more robust evidence base, strengthening DfT’s decision-making, ensuring public money is spent efficiently, policies are well-targeted, uncertainty is reduced, and anticipated benefits are achieved

This ARI sits alongside DfT’s Science Plan, which sets out our ambition for the role of science in DfT strategy, policy and delivery. It identifies 3 areas for action:

• people: action to build a diverse and scientifically skilled workforce both within DfT and the broader transport sector
• partnerships: the necessity of working in partnership with policy, across government, and with the wider transport R&D sector to enable efficient and effective action at pace
• purpose: embedding science in DfT decision-making, ensuring focus on departmental purpose, and ensuring the right mechanisms to deliver impact

Please note that the shorthand ‘science’ is used to refer to the broad range of scientific activities across DfT, including natural sciences, social science, engineering, and innovation, sitting alongside analysis which includes economics, social and behavioural research, operational research, modelling, and statistics.

Scope

This 2023 ARI has taken each of DfT’s strategic priorities and identified the key priority questions that sit under them. This provides a clear picture of DfT’s priorities and identified where we believe we can best work with the external research community to deepen our understanding and provide the evidence required to deliver real progress against our strategic priorities.

Alongside these research questions, the ARI continues to list more detailed questions that have emerged directly from teams across DfT. These tend to be slightly more short-term and represent the topics where further research is most likely to have an immediate positive impact on policy.

The purpose of this ARI is not to constrain the research done but to provide clarity and guidance on our priorities. DfT’s research and evidence requirements are extensive and continue to evolve. Neither the priority research questions, nor the more detailed questions represent an exhaustive list of our needs; it is simply intended to open conversations. Research outside the areas outlined below may still be relevant to DfT policy or delivery.

DfT’s use of evidence

Research and evidence are critical to robust policy and delivery and DfT has a strong history in the use of evidence to support policymaking.

How DfT generates and uses research evidence and expertise

Of all the evidence DfT uses, the smallest proportion is directly commissioned. We also work with the broad transport R&D sector to influence and collaborate on external research programmes, and most importantly we identify, understand, and exploit existing research and expertise.

1. Exploit existing evidence, research and expertise

This stage forms the basis for our understanding and largest proportion of our research activity. We do this via:

• DfT’s Science Advisory Council
• direct engagement and calls for evidence
• literature reviews

2. Influence and collaborate with others

In this stage we identify existing areas of research and engage external colleagues via:

• DfT’s Transport Research and Innovation Board
• partnership with UK Research and Innovation
• shared priorities with other funders
• engagement with academic consortia and external events

3. Commission research

And finally, the smallest proportion of our research are commissions. We do this through:

• directly commissioning via open competitions or framework agreements
• grants to enable long term partnerships
• sponsorship of individuals through fellowships, internships and PhDs
• in-house research and analysis

Figure 2 - graphic of how DfT generates and uses research evidence and expertise

DfT covers an extensive range of policy areas, so the evidence we use is varied and requires a breadth of methodologies, including:

• reviewing and synthesising existing evidence, research, and expert knowledge
• conducting secondary analysis / meta-analysis of existing data sources
• new evidence generation, both qualitative and quantitative
• developing analytical tools for modelling and forecasting
• evaluating policies and investment programmes
• monitoring and surveillance
• data analytics and data visualisation
• research and development projects to prove concepts and test ideas
• trials, pilots, living labs and demonstrators

There is much transport can learn from other parts of the transport system (for example, sharing learning across modes) and from other disciplines beyond the transport realm. Innovations in methodologies, processes and techniques often come from adjacent or even completely unrelated fields. We are therefore keen to engage and work with disciplines beyond traditional transport research and analysis providers, and to work with inter-disciplinary groups which can better reflect the increasing interconnectedness of the transport system’s evidence needs.

Role of DfT arm’s length bodies

DfT arm’s length bodies (ALB) are a critical element to the effective delivery of DfT’s ambitions and the smooth running of the transport system. While our ALBs have their own considerable research and development needs and activities, we work closely together to understand each other’s challenges, R&D priorities and to identify potential synergies. Their evidence and research needs are not captured in this ARI as they have their own processes for engaging the community.

DfT’s strategic priorities

Transport is fundamental to where people live, where they work, where they socialise; it is an essential enabler of business. DfT plans and invests in transport infrastructure to keep the UK on the move.

DfT has 5 strategic priorities that sit at the heart of DfT decision-making. The plan for achieving these is outlined in DfT’s Outcome Delivery Plan.

Our 5 strategic priorities

Grow and level up the economy

Grow the economy and improve connectivity across the United Kingdom by enhancing the transport network, on time and on budget.

Improve transport for the user

Build confidence in the transport network and improve transport users’ experience, ensuring that the network is safe, reliable, and inclusive.

Reduce environmental impacts

Tackle climate change and improve air quality by decarbonising transport, mitigating wider environmental impacts, and ensuring the transport system is resilient to climate-related change.

Increase our global impact

Boost our influence and maximise trade by having an innovative outward-facing approach.

Be an excellent department

Be a well-run department that focuses on delivery, demonstrating excellence in transport policy, driving value for money, and embodying our values in all that we do.

DfT’s priority research questions

Research and evidence are crucial to driving progress against these strategic priorities. Working with the senior responsible owner for each strategic priority, we have identified the priority research questions for each. These are the strategic, medium- to long-term questions that will be crucial to their successful delivery.

Improve transport for the user

The improve transport for the user strategic priority is critical in ensuring the department delivers and maintains a transport system that meets the needs of the public and addresses what they care about most.

It puts the needs and expectations of current and potential users (both passengers and freight customers) at the heart of the operation of the transport system and considers about end-to-end journeys, not just individual transport modes. It is focused on ensuring that our infrastructure and the services which use it meet the varied needs of businesses and the public, are attractive, affordable, sustainable, and resilient is a crucial goal for the department.

Question 1. How can we ensure the transport system is putting users at its heart?

For example:

• How do we best understand and measure user experience and accessibility and embed this into decision-making?
• How can we understand how new solutions work in a local, real-world setting including considerations around how the general modern-day workforce will look?
• How do we design the transport system to work for users in urban, peri-urban and rural areas?
• How can we effectively consider end-to-end journeys to ensure the system is designed for the user?
• How do we ensure development of transport systems considers the needs of the business community and the supply chain?
• How do we ensure equity within the transport system, including enabling fair access to novel technologies and environmentally sustainable options?

Question 2. How do we prepare for the potential impacts of emerging technologies?

For example:

• How should we prepare the transport system to both incorporate beneficial new technologies and become resilient to those that pose risk?
• How can we harness AI and Machine Learning to deliver improved transport services nationally and locally?
• How do we effectively transition new technologies into the transport system, so they benefit and are accepted by users?

Question 3. How do we ensure the transport system is safe, secure, and resilient?

For example:

• How can we best understand and improve the safety of vulnerable users, including women, on the transport system?
• How should we continue to enhance the safety of operators of vehicles and the transport system?
• What are the security and resilience threats we face; how can we better anticipate these and what evidence do we need to inform decision-making? For example, those from Position Navigation and Timing, digitisation/cyber, artificial intelligence and autonomy, security systems, and climate change.
• How can we improve the resilience of the transport system while maintaining efficiency?

Question 4. How can we enable smoother multi-mode journeys, including more active travel?

For example:

• How can we encourage more active travel? What are the safety barriers to this and how can they be overcome?
• How can we ensure the transfers between modes (for example, from rail to bus, or from public transport to active travel) are smoother?
• How can user’s accessibility needs be adequately catered for in transfers between modes?

Question 5. How will social and economic changes influence how people use transport?

For example:

• What changes are likely to produce behaviour change and how are these likely to impact the user (including the public, businesses, and supply chains)?
• How should government best anticipate and monitor societal and economic changes and their impact in the future?

Reducing environmental impacts

The reducing environmental impacts strategic priority is in recognition that there is an environmental aspect to all transport, and therefore almost all the work of DfT. Transport is the largest emitting sector of greenhouse gases in the UK, contributing 27% of domestic emissions in 2019. Our transport system must change to deliver the government’s Net Zero ambition and DfT will drive forwards that change through our longer-term green transport agenda.

On decarbonisation specifically, we published our Transport decarbonisation plan (TDP) in July 2021, which sets out the steps we will take to deliver the necessary carbon reductions across every form of transport. Sustainability will be at the heart of levelling-up. People everywhere will feel the benefits – villages, towns, cities, and countryside will be cleaner, greener, healthier and more prosperous and pleasant environments in which to live and work

Question 1. What are the new technological innovations needed to reduce transport‘s environmental impacts, including decarbonisation, adaptation, air quality, and biodiversity?

For example:

• What are the best-fit and cost-effective technology pathways to meet our Transport decarbonisation plan and our adaptation, air quality, and biodiversity goals?
• Where are there potential synergies and/or conflicts between our different environmental goals and how can they be overcome?
• What innovation is required to support more difficult to decarbonise modes, such as HGVs, maritime, and aviation?
• How can new technologies be used and integrated to ensure the removal of embodied carbon in transport infrastructure?

Question 2. How can existing technologies be accelerated and scaled-up to achieve our environmental goals, including decarbonisation, adaptation, air quality, and biodiversity?

For example:

• What is the capacity of these technologies to be scaled up/accelerated/moved up the TRL scale?
• What are the challenges, including regulatory barriers, and how can they be overcome?
• What can the government do to support commercialisation?
• What regulation, safeguarding, or guidance is required to embrace new technologies into the existing network?
• What are the challenges of implementing technology solutions at scale, and how can they be overcome?

Question 3. What behavioural change will be required to meet our environmental goals (decarbonisation, adaptation, air quality, and biodiversity), and how can this be achieved?

For example:

• What are the driving factors that encourage uptake of new technologies?
• How do people’s behaviour and technology interact?
• How can people be encouraged and supported to make green choices when it comes to transport?
• How can technologies make lives better through changing the journeys people need to make?

Question 4. What are the systems-level requirements to achieve our environmental goals to ensure the transport system is both efficient and resilient?

For example:

• What are the demands by mode and as a system and how is this likely to change over time?
• What reduction is required and how can this best be achieved across the system?
• How best can transport be fully integrated into the energy system?
• What are the implications for our energy networks and how can these challenges be overcome?
• How can resilience to climate change be built into the transport system?

Grow and level up the economy

The grow and level up the economy strategic priority is at the heart of the government’s agenda to spread opportunity across the UK. Transport has a crucial role to play, whether it be through improving connectivity across the United Kingdom and growing the economy by enhancing the transport network, on time and on budget. DfT has a number of specific interests in this space, notably our infrastructure projects, Places for Growth and our apprenticeships and skills work.

Question 1. How can investment in future transport infrastructure (for example, high-speed rail) lead to accelerated change in the economy and subsequent levelling up?

For example:

• How can we build on current evidence bases to best ensure transport infrastructure projects are efficient, effective, and innovative?
• What transport interventions in both disadvantaged and left-behind places will make the biggest difference?
• What are the likely impacts of inter vs intra city transport investment on the wider economy?
• What impact does transport have on local skills and jobs?
• What can we learn from existing major infrastructure schemes?
• How can major infrastructure projects stimulate and support innovation?
• What impact does transport have on wellbeing and what are the conditions where new transport investment would have the biggest impact?
• What are the major economic opportunities in improving transport infrastructure?

Question 2. What interventions will continue to restore traveller confidence and drive mode shift towards public transport use?

For example:

• How does this differ between different types of areas (for example, rural, urban, coastal, and peri-urban)?
• What is likely future demand for public transport in different areas, and what will influence this demand?
• What is the likely impact of emerging technologies on demand for public transport?

Question 3. What incentives encourage certain types of travel behaviour and why? How can this be utilised to achieve government levelling up objectives?

For example:

• What are the options for funding public transport, especially larger projects and rail, to both ensure maintenance of key services and fair public access?
• How can price signals drive behaviour change? How do they relate to other potential levers?
• How do financial levers sit alongside other incentives? What is the right package of interventions to achieve desired outcomes?
• How does this differ between different user groups (public vs business)?

Increase our global impact

Increasing our global impact recognises the UK’s opportunities in the world and the importance of DfT contributing effectively toward the government’s vision of a global Britain. Operating and engaging globally will play a vital role in assisting the department in maintaining and extending its influence with international partners, including ensuring high standards of transport safety, security, and environmental protection and boosting UK trade, exports, and inward investment.

UK science and innovation has the potential to develop transport-related exports and inward investment, thereby helping grow and level up the economy. Our R&D around climate change mitigation and adaptation can help influence the international community to take progressively stronger action.

Question 1. How can we embed learning from international contexts into the UK transport system? Where are the major opportunities for strategic international partnerships?

For example:

• What are technologies being accelerated internationally that we will be able to adopt and adapt in the UK?
• Where do we need bespoke solutions for the UK setting?
• What opportunities do we have to lead internationally in transport science and innovation?
• How can we use UK evidence to influence international vehicle standards?
• How do we maximise the UK’s trade exports from the investment in UK innovation and technologies as well as encourage inward investment?
• How can we utilise R&D in the transport sector to be a facilitator of international engagement and trade?

Question 2. What metrics will we need to develop to understand the effectiveness of global focused investment and global collaborations?

For example:

• What data and information should be collected to deliver a solid evidence base and support policy decisions?
• What is the role of Environmental, Social and Governance (ESG) measurement in central and local government decision-making?
• To what extent do international indexes/ranking systems reflect the role of transport and its global impact/importance? Where are the opportunities, investments and interventions that could alter UK performance?
• How do we measure the success and impact of international science and innovation partnerships (including both quantifiable and not quantifiable)?

Question 3. How will innovation and transport change in the UK interact with international change?

For example:

• When do we need to work with international colleagues to achieve our goals (for example, Net Zero)?
• What activities/contexts internationally do we need to understand to make significant progress in UK (for example, maritime, aviation)?
• How do we ensure we are aligned with changes internationally that will impact the transport system (for example, Energy systems and demand)?

Be an Excellent Department

Our strategic priority of ‘Be an Excellent Department’ drives the way DfT works and determines the way in which we integrate analysis, science, and innovation into all our thinking and use the evidence base we develop, both directly, and through working with partners on the back of the ARI and other engagement activities. Being an excellent department extends to the work we commission and collaborate on externally and provides the evidence we are delivering value-for-money for the taxpayer.

Our strategic priorities cannot be delivered without effective supportive processes, technology, and people, in a way that works collaboratively with our partners and focuses delivery. Working closely and productively with the wider transport research community is an important part of this ambition.

Detailed research and evidence need by DfT directorate

Beyond the priority research questions set out in the main body of the ARI, this section lists detailed research questions identified across a number of DfT’s directorates. This is a long list, designed to give an insight into the evidence needs of the whole department in more of a “bottom-up” fashion and complement the more strategic questions already presented.
