    “I love public transport, but now I’m too afraid to use it”: A qualitative study of public transport use cessation among older adults Open Access

    Abstract

    Mobility is a hallmark of functional ageing and a major health determinant in older adults. Mobility is known to decline with age, yet, except for research on driving cessation, little is known about the role of giving up other transport modes in this decline. This exploratory qualitative research focusses on public transport use, and aims to describe the process of

    Transport Justice in Sub-Saharan Africa Challenges, tools, perspectives

    Abstract

    Prevailing methods of transport planning focus on the functioning of transport systems rather than on the services people receive from those systems. In line with this perspective, and as epitomized by the four-step model, road congestion has been seen as the main transport problem, and investments to ease congestion are given priority. This approach, still very dominant

    Determining people’s ease and difficulty of movement based on observed travel behavior

    Diana Saadi, Karel Martens
    Abstract

    This paper presents an approach to use GPS-based travel behavior surveys to determine who is being served well and who is being served poorly by the transport system. We draw on the extensive literature on travel behavior, which has shown that people’s travel behavior is at least in part shaped by the travel barriers they experience. Starting from this basic insight

    Urban roads and walking: Exploring pedestrian perceptions and experiences in a Sub-Saharan African City

    Abstract

    Amidst rapid urbanization and increasing motorization, walking remains a widely used mode of transport in Sub-Saharan Africa (SSA). The frequency with which people walk, the distance for which they may be willing to walk, and the convenience and safety with which they can walk, depend significantly on road design. Moreover, the impact of roads on walking behavior will

    Examining the health effects of public transport use on older adults: A systematic review

    Abstract

    Background and aim Public transport use has been linked to several health benefits in the general population and is crucial for older adults’ mobility, due to an age-related decline in physical and cognitive capacity and mobility, particularly the ability to use other modes of transport. The objective of this systematic review is to determine what is known about the

    Relations Matter: Toward Relational Egalitarianism in Transport

    Abstract

    This paper proposes a relational egalitarian framework for conceptualizing justice in transport planning and policymaking. Building on Elizabeth Anderson's work, we argue that transport justice should be understood in terms of dismantling oppressive social hierarchies rather than merely redistributing resources. The paper outlines three key dimensions of relational

All interviewees regularly treat clients facing challenges using various modes of transportation due to anxiety disorders. Their clients exhibit a range of mobility issues, with some struggling with

    The Dual Processes of Fragmentation and Integration in Transport Tendering: Understanding Transport Integration in a Unitary National Government

    Abstract

    A high level of integration of public transport services in terms of scheduling, ticketing, and cross-operator data provision and others is crucial to provide a high level of service to potential users. Transport integration issues are a growing need as transport providers consider low cost ways of increasing ridership following the travel pattern disruptions exacerbated

    Sustainable Travel: Are Leading Companies Doing Better?

    Abstract

    Every workplace has an explicit or implicit transportation policy with respect to its employee mobility. Whether it is officially managed or not, employer's policies regarding parking provision, travel allowances and other transport related financial or non-financial benefits affect employee transport-related decisions, such as vehicle ownership and mode choice. These
