Description

This paper discusses the methodological framework for examining the current spatial supply structures of three types of shared mobility services (car-, bike-, and e-scooter) to develop a typology according to socio-economic and socio-cultural characteristic of potential users. It forms part of the DUT-funded project, Share4Equity, which aims to explore the current and potential contribution of shared mobility services to help realise the ideas of equitable transport, mobility justice and the 15-minute City. Previous research finds that marginalised users are generally more exposed to negative impacts of transport decision making, and they often face accessibility inequalities as new mobility services emerge. Furthermore, the digital divide and differences in competences and capabilities in using shared mobility services between different population groups are considered as one of the main causes for creating new forms of transport inequalities. Transport justice is one means of examining how opportunities for shared mobility are distributed across society and how to reduce car-dependency in the 15-minute city context. In our research, three dimensions of transport justice (distributive, procedural and epistemic) will be used to analyse: 1) the supply and distribution of shared mobility services, 2) user perceptions and experiences, and 3) the inclusivity of different forms of sharing. Research presented in this paper focuses on the supply structures of shared mobility options, using case studies from European countries (Germany, Sweden, Italy, and Poland) and from Canada, ranging from privileged inner-city districts to car-dependent peri-urban areas. The comparison will inform the current state of supply: 1) by visualising (un)even spatial distribution of shared mobility, and 2) by substantiating whether large cities are advanced units of progress. Drawing on previous work (Groth et al, 2023), we present our methodological framework for evaluating the supply structures of selected cities or city regions and for visualising the spatial supply patterns of shared services. We plan to intersect them with spatial and census data on residents’ socio-economic characteristics in different administrative districts of case study cities/regions. We aim to elaborate which types of variables correlate with supply patterns (distributive dimension) in order to reveal determinants of the current spatial distribution of service supplies.
