Transport poverty is an issue that has never fully captured the interests of the transport engineering profession in either the 'global north' or 'global south' and yet it is a problem that adversely affects the daily lives of millions of people across the globe. What precisely constitutes transport poverty is not adequately articulated within academic, policy or infrastructure design literature. This paper aims to demonstrate how the different ways that academic studies and policy programmes have defined and recorded the problem of transport poverty is directly related to the ways in which it has been subsequently addressed in practice. The overall impression is one of inadequacy, fragmentation, inconsistency and tokenistic treatment of an issue that potentially affects anywhere between 10 to 90% of all households, depending on which definition is used and which country is being considered. This suggests that it is a far greater problem than the transport profession has previously been prepared to recognise and one that requires its urgent attention given the continuing trends for mass migration, urbanisation and wealth concentration within and between the 'global north' and 'global south'.

The world is currently witnessing its largest surge of urban growth in human history; a trend that draws attention to the need to understand and address health impacts of urban living. Whilst transport is instrumental in this urbanisation wave, it also has significant positive and negative impacts on population health, which are disproportionately distributed.In this paper, we bring together expertise in transport engineering, transport and urban planning, research and strategic management, epidemiology and health impact assessment in an exercise to scope and discuss the health impacts of transport in urban areas. Adopting a cross-disciplinary, coproduction approach, we explore the key driving forces behind the current state of urban mobility and outline recommendations for practices that could facilitate positioning health at the core of transport design, planning and policy.Current knowledge on the health-related impacts of urban transport shows that motor vehicle traffic is causing significant premature mortality and morbidity through motor vehicle crashes, physical inactivity and traffic-related environmental exposures including increases in air pollution, noise and temperature levels, as well as reductions in green space. Trends of rapid and car-centred urbanisation, mass motorisation and a tendency of policy to favour car mobility and undervalue health in the transport and development agenda has both led to, and exacerbated the negative health impacts of the transport systems. Simultaneously, we also argue that the benefits of new transport schemes on the economy are emphasised whilst the range and severity of identified health impacts associated with transport are often downplayed. We conclude the paper by outlining stakeholders recommendations for the adoption of a cross-disciplinary co-production approach that takes a health-aware perspective and has the potential to promote a paradigm shift in transport practices.

We provided an overview of the current state-of-the art of HIA in cities and made recommendations for further work. The process on how to get there is as important and will provide answers to many crucial questions on e.g. how different disciplines can effectively work together, how to incorporate citizen and stakeholder opinion into quantitative HIA modelling for urban and transport planning, how different modelling and measurement methods can be effectively integrated, and whether a public health approach can bring about positive changes in urban and transport planning.

In this paper, we propose a mixed methods quantitative and qualitative approach to capture fully the measurable and less tangible social impacts of transport projects on local people and communities. The approach was used to assess the potential social impacts of a strategic road by-pass project case study in a deprived region of Wales in the UK. The project specifically aimed to stimulate local economic growth and regeneration in the local areas it serves. In a ‘before and after’ case study, we combined fine-grained, GIS-based spatial analysis of secondary datasets with qualitative participative exercises with the local residents of the five communities living adjacent to the road, and interviews with professional local stakeholders. This mixed methods approach significantly enhanced understanding of both the social benefits and disbenefits of the road project. It helped to reveal local concerns that would not otherwise have been apparent from secondary dataset analysis alone. The qualitative studies were also successful in bringing to the table new ‘hard to reach’ voices that had not been heard through the formal consultation and public engagement process. The study revealed that the social benefits accruing to local people from the project could have been significantly enhanced, whilst a number of its locally occurring negative social impacts could have been avoided had social assessment been employed earlier in the decision processes concerning its routing and design. Recommendations to improve the practice and uptake of social assessments at the option appraisal, project design mitigation and post evaluation stages of transport projects are included in the paper.
