DOI 10.60531/INSIGHTOUT.2024.2.8| LAI: SMART CITY TRANSITION_ INSIGHTOUT 2(2024)50Marginalised citizens in thedigitalisation eraElaborating on smartphone ownership becominga basic human right in an increasingly digitalisedsociety,20its lack is also exacerbating the social disparities brought about by the emergence of urbantechnologies. While smartphone usage is changingcitizens’ daily practices, smartphones had alreadybecome the main ICT device for users to interactwith transportation systems even before the inevitable impact of the pandemic.21Besides themultimodal travel behaviour which is the key concept of MaaS, enabled by SBMS,9, 22access to real-time information, ticket-purchasing functions androute-planning are almost exclusively offered bymobile apps,9, 23let alone some new mobility forms,especially shared mobility services, which are onlyavailable and accessible via SBMS.22At this point,it becomes necessary to question if a smartphonenon-user – whether due to the unaffordability ofsmartphone ownership, a lack of the skills neededto use a smartphone, or even the rising ethical concerns of digital services – would be excluded fromthe mainstream digitalised transit and thus if dependence on smartphones creates another form ofsocial exclusion.10, 24Several scholars have already conducted studiesregarding the exclusion of smart city transition andconceptualised the most impacted groups under anew term –“digital underclass”.25Older adults are often vulnerable in termsof access to technologies;20a lower education level is another factor denying somethe skills needed to use these technologies;22, 26low-income individuals are at a higher risk of beingexcluded from mobile apps;27disabled individualsface limitations with certain digital interfaces.28Evenamong smartphone users, a disparity is observed between smartphone ownership and the acceptanceof urban technologies, implying privacy concerns.29Gender as a demographic factor has also been extensively studied, with findings often diverging. Whilesome have argued that women are more vulnerablein the digitalisation era due to their higher privacyconcerns and lower ICT knowledge,30this observation has not consistently been supported in otherstudies.28Given this debate, this paper centres ongender within the context of smart mobility studies.20M.
