HABITS will take ‘track and trace’ (T&T) data collected in a transport policy context and explore the challenges, opportunities, methodologies and policy implications related to its use in reducing individual health burdens. HABITS will explore how new insights from T&T data can inform policy making in Transport and Health/Wellbeing, making it easier to identify areas at the boundaries of transport and health that require better targeted interventions. HABITS will also explore the tools, techniques and methodological improvements that are needed to allow T&T data to be linked and interoperated with established data and models from the Transport and Health sectors.
