20. Given emerging technologies, how effective is mode shift likely to be in delivering the environmental and health outcomes we want to improve?
Background
DfT’s ARI identifies 40 broad research questions that reflect areas of strategic importance to the department, where further insight and collaboration could enhance our evidence base, challenge assumptions and strengthen future decision-making. The ARI is organised around four complementary themes, and this question sits within the Delivering Green and Healthy Transport theme.
Transport has a significant influence on environmental outcomes and public health, shaping greenhouse gas emissions, air quality, noise, physical activity and the resilience of communities to climate change. Decisions about how transport systems are planned, operated and used therefore play a critical role in tackling climate change, protecting the natural environment and supporting healthier lives.
This theme recognises that environmental sustainability and health outcomes are closely linked, and that transport interventions can deliver multiple benefits when these objectives are considered together. Cleaner vehicles and fuels, safer and more attractive streets, and shifts towards walking, wheeling, cycling and public transport can reduce environmental harm while improving physical and mental health, including through improved safety outcomes. At the same time, transport has negative effects on safety, air pollution, noise, inactivity and climate risks which we aim to reduce.
Transport’s environmental and health impacts are shaped by interactions with wider systems, including energy, the built environment, nature and public health. Understanding these interactions is essential to addressing long term challenges such as decarbonisation, climate adaptation, air pollution and health inequalities, and to ensuring that transport interventions deliver lasting benefits across different places and population groups.
Delivering green and healthy transport requires action across multiple timescales and levers, from technological change and infrastructure investment to behaviour, service design and spatial planning. The ARIs therefore seek research that deepens our understanding of how transport can reduce environmental harms and support better health outcomes.
