Unmet travel needs can be defined as trips and activities that people need or would like to do more, but for a variety of reasons they are prevented from doing so. This paper provides a critical evaluation of the literature focused on unmet travel needs, with the aim of assessing the scope of existing studies on this topic and better understanding the full context of older people’s mobility. This narrative review identifies how travel needs in later life have been assessed, and the barriers that affect the ability of older people to fulfil these needs. Due to the heterogeneity of older people and differences in research approaches, the analysis of the literature is not conclusive in terms of identifying the real impact of the analysed variables and measures on unrealised mobility. Nevertheless, of the studies analysed, on average at least one-third of older people report unmet travel needs. This situation was found to worsen with age, and women were reported to be more affected than men. The pursuit of leisure, and in particular visiting friends and family, was found to be the activity most associated with unmet travel needs.

Recent research related to transport gerontology argues that the autonomy, flexibility and independence provided by the car are fundamental in fulfilling travel needs in later life. Statistics show that in the western world the car is the most used mode of travel among the older population. Despite the importance of promoting transport policies to incentivize people to switch to more sustainable forms of transportation, alternatives to the car are still underused by older people. The aim of this scoping review is to analyze the transport barriers affecting the use of alternative modes to the car in later life. The paper investigates how issues related to personal security, health impairments, service provision, affordability, comfort, attitude, built environment, information and awareness of all transport modes influence modal choice. The analysis of the literature shows that despite the benefits provided by public transport, flexible transport services, taxis, walking and cycling, there are still several factors that negatively affect the use of these modes. The paper concludes by reflecting on potential solutions that might help to create a transport system less reliant on the car and which is able to meet the mobility needs of the older population.

Globally, climate change represents the most significant threat to the environment and socio-economic development, endangering lives and livelihoods. Within the UN’s current 17 Sustainable Development Goals (SDGs), climate action is explicitly covered under Goal 13, “to take urgent action to combat climate change and its impacts”. This perspective considers how to re-frame the SDGs and their successor towards mainstreaming climate action within the targets and indicators of all the development goals.

Globally, the transport sector is a major contributor to air pollution. Currently, in the UK, vehicle emissions contribute significant amounts of nitrogen oxide (NOx) and particulate matter (PM) pollution in urban areas. Low-emission-zone policies have been used as an intervention to tackle air pollution, and in this context, the UK launched the Low-Traffic Neighbourhood scheme. This study investigates the impacts of the Low-Traffic Neighbourhood in Kings Heath, Birmingham, UK, to evaluate its impact in reducing air pollution and local community perspectives about the scheme and perceived impacts on health and well-being. This study employs a mixed-method approach comprising an air-quality-monitoring assessment and a survey questionnaire involving 210 residents. The findings reveal an increase in active travel and a reduction in air pollution levels in the years after the implementation of the scheme, although the area is still non-compliant with the 2021 WHO air quality guidelines. Nonetheless, the scheme has a polarising effect and created a division within the local community about the overall scheme acceptance and spatial distribution of the scheme’s benefits. This study underscores the importance of comprehensive baseline data, long-term community engagement, and integration with broader urban planning initiatives to enhance the success of future Low-Neighbourhood Traffic schemes.
