    Transport Policy, 2026
    This study explores how older people perceive emerging transport technologies, designed to reform the future of mobility. With older populations rising dramatically and being on the one hand the age group most vulnerable to social exclusion and on the other hand increasingly influential in societal structures, the transport sector is under pressure to adapt to their diverse and sometimes specialised mobility needs. In this context, the study explores older people’s perceptions of Autonomous Vehicles (AVs), Mobility-as-a-Service (MaaS), assistive technologies, real-time information systems and travel apps, focusing on their potential to enhance autonomy, accessibility, and mobility. In particular, we study older people’s self-reported intention to use them. Data were collected via a face-to-face quantitative survey targeting residents aged 60 and over living in North England; a rare and laborious data collection approach in a dynamic UK region, fit for people often underrepresented in digital mobility research. We used descriptive statistics, ANOVA tests and ordinal regression to study their technology adoption decision-making. Findings reveal mixed attitudes: while older people recognise the benefits of increased independence and tailored mobility, concerns about affordability, ease of use, and digital literacy also emerge. ANOVA tests demonstrate that socio-economic characteristics like the educational background, driving license holding, internet usage and income are major factors underpinning older people’s perceptions of emerging transport technologies. Moreover, the intention to use these initiatives is statistically associated with the importance a participant ascribed to their own transport accessibility, experience with technology, concerns of safety, cost savings, access to training and driving license holding. Our study ultimately voices the importance of inclusive design and policymaking to prevent the digital marginalisation of older people and calls for targeted older age-specific educational and awareness-raising initiatives to build trust and engagement with a future mobility paradigm that seems inevitable. • Emerging transport technologies such as AVs, MaaS, travel apps, assistive and real-time information systems, are a disruptor that may disproportionally affect older people. • A face-to-face survey completed by 200 people aged 60 and over in North England enabled the study of the factors affecting their intention to use these technologies. • Older people recognise benefits in these high-tech options including accessibility, personalised options, autonomy, yet, they remain sceptical about their affordability, privacy, ease of use and potential risks like fraud and cybersecurity breaches. • Familiarity with technology, perceived value of own transport accessibility, access to training initiatives, travel cost reduction, having a driver’s license and safety concerns emerge as the key predictors of older people’s intended use of these interventions. • Awareness-raising and trust-building exercises providing training, helplines and educational campaigns but also user-centric cyber-secure design of affordable, inclusive and easy to use products will make these technologies ageing-friendly.
  • An in-depth investigation of time and space-based accessibility inequities in the public transport system of Athens, Greece
    Stefanos Tsigdinos, Theodore Chatziioannou, Panagiotis G. Tzouras, Konstantinos Kepaptsoglou
    Case Studies on Transport Policy, 2026
    • Spatiotemporal variations are thoroughly examined using advanced geospatial indices. • Spatial disparities between central and suburban areas are found. • The public transport system does not consider the commuters’ patterns. • “Time-based inequity” does not emerge, inequities are constant throughout the day. • Night-time services, increased frequency and improved coverage should be prioritized. Urban public transport systems often exhibit uneven accessibility across space and time, raising critical concerns about transport equity and particularly about captive travelers (i.e., older adults and zero-car households). While current studies frequently assess public transport accessibility or equity at static time points, limited evidence exists on how spatiotemporal variations jointly shape horizontal and vertical inequities throughout the day. Using data from the Athens Metropolitan Area (AMA), Greece, this paper investigates in detail the spatiotemporal variations in public transport accessibility and equity for captive travelers throughout a typical day. The Gini coefficient (a measure of inequality in the distribution of accessibility) is exploited for assessing horizontal equity, while vertical equity is evaluated through the Concentration Index (measuring whether accessibility is disproportionately distributed among disadvantaged groups) and Bivariate Local Moran’s I (a spatial autocorrelation statistic identifying spatial clusters between accessibility and the distribution of captive travelers). Findings reveal significant variations in public transport accessibility, with early morning and evening hours exposing low accessibility values, whereas morning and afternoon illustrate better conditions. These variations declare a mismatch between the supply side of public transport and the demand in AMA. Delving into the temporal aspect, the persistence of inequity throughout the day suggests a structural rather than a temporal equity problem, raising serious concerns about the city’s public transport system. These intriguing outcomes are also analyzed through a spatial lens identifying serious geographical disparities between central and suburban areas. This analysis unveiled spatial clusters of low accessibility and high proportion of the least well-off. Apparently, spatial disparities are more pronounced than temporal ones. Building upon the results, several indicative policy implications are outlined, such as providing extended night-time services, improving frequency during very early and evening hours, expanding the public transport system (mainly the metro network) to suburban areas and the outskirts or even rethinking the distribution of land uses in these underserved areas. The study’s findings could be meaningful to both academia and planners that strive to ensure public transportation is truly accessible and equitable throughout the day, accommodating the needs of captive travelers.
  • Accessibility challenges for older adults and people with disabilities: An urban mobility perspective in the age of smart transport technologies
    Christos Karolemeas, Stefanos Tsigdinos, Erika Aliaj, Efthimios Bakogiannis, Alexandros Nikitas
    Cities, 2026
    In times defined by a rapid transition towards a smart technology paradigm, accessibility remains a key prerequisite for social inclusion, equity and quality of life, especially for populations with special mobility needs like older adults and people with disabilities. This study meticulously reviews the existing literature to identify barriers and opportunities related to the mobility of these vulnerable groups within urban transport systems. Using systematic, narrative, thematic and bibliometric literature review tools, the study synthesises the findings of 60 studies from various disciplines, including transport, urban planning and social sciences. The outcomes illustrate that inadequate road infrastructure, such as poorly maintained sidewalks, inaccessible public transport stops and vehicles as well as insufficient tactile and auditory aids, severely limit mobility and independence. Public transport systems often lack user-friendly design, functional support for mobility aids and adequately trained staff. Technological advances, while promising, pose a challenge in terms of compatibility and accessibility for these groups; digital literacy and ease of use are factors that cannot be ignored. Policy recommendations are proposed to address these barriers, focusing on improving infrastructure, adopting inclusive design principles and enhancing services, affordability and staff training. Also, integrating and simplifying innovative transport technologies, like Connected and Autonomous Vehicles (CAVs), Mobility-as-a-Service (MaaS) and digital mobility tools, to support equitable and inclusive mobility is a critical way forward. This study's findings highlight the interdisciplinary nature of transport accessibility research and the need for a holistic and universal approach to urban and transport planning. By addressing these challenges, policymakers and practitioners can significantly improve the autonomy, participation and well-being of older adults and people with disabilities, promoting a more liveable built and road environment. • Accessibility and mobility are two interlinked societal needs that may define not only access to travel and destinations but for some vulnerable populations even their quality of life per se. • This study reviews narratively and systematically 60 studies to identify and contextualise the transport barriers that older adults and people with disabilities face in urban eco-systems. • Infrastructure, socio-psychological, financial and service barriers are recognised spanning from concerns around inadequate road infrastructure and digital illiteracy to unaffordable travel and problematic public transport provision. • Targeted solutions are proposed around improving infrastructure, inclusive design and technology adoption and enhancing services, affordability and staff training. • Building accessible urban transport for all is a pathway to more liveable cities.
  • Sustainable mobility oases and their relationship with car ownership and mode share
    Hans-Heinrich Schumann, Stefanos Tsigdinos, Theodore Chatziioannou, Craig Morton, John Weightman
    Journal of Transport Geography, 2026
    <p dir="ltr">Accessibility describes the ease to reach desired destinations and can be achieved through either mobility- or proximity-focussed policies. While car-centric planning focusses on the former, planning paradigms aiming to provide favourable conditions for sustainable travel highlight the latter. Established metrics to measure accessibility such as distance or travel time fall short of acknowledging the relevance of personal characteristics, time-of-the-day, infrastructure, multi-modality, and popularion distribution to providing feasible alternatives to car usage. Addressing these gaps, this study presents the concepts of Sustainable Mobility Deserts (SMDs) and Sustainable Mobility Oases (SMOs) to interpret accessibility through a multi-modal and inclusive lens. Data from the university market town of Loughborough, UK, is used as a case study to provide detailed insights into multi-modal deficiencies in the supply of sustainable transport options, revealing significantly higher deprivation levels in SMDs compared to SMOs. Based on the findings, the study proposes options to address the identified deficiencies, underscoring the potential of the SMO/SMD concept to inform planning practices, evaluate new developments, prioritise infrastructure investments, and assess the impact of demographic changes.
  • Shared autonomous vehicles for older adults and people with disabilities in Greece: An isolation amplifier or a social inclusion facilitator?
    Christos Karolemeas, Kalliopi Michalakopoulou, Ioannis Chatziioannou, Stefanos Tsigdinos, Efthimios Bakogiannis, Alexandros Nikitas
    Journal of Transport and Health, 2026
    The time when Shared Autonomous Vehicles (SAVs) are set to make transport driverless and not privately owned or used, is nearing even for countries which have not been thus far in the forefront of vehicle automation discussions. SAVs have the potential to make traditional and long-standing barriers to mobility, like ageing and disability, obsolete provided that they are designed to cater for the special needs of vulnerable populations closer to transport-related social exclusion. Our study uses 32 semi-structured interviews with Greek stakeholders, who know the accessibility landscape of SAVs or represent vulnerable groups and their rights, in order to specify and contextualise how SAVs can support the special travel needs of older adults and people with disabilities. We do that by decoding, through a six-step literature review-informed thematic analysis, their insights around the SAV accessibility discourse. Four dominant themes, each with their distinctive dimensions and expressions, emerge namely: infrastructure and the built environment, inclusive technology, scepticism and reality check and policy and governance . We conclude that SAVs are described as a positive, in principle, but at the same time deeply disruptive change that may be premature for a transport ecosystem that is yet to fix basic problems like the lack of infrastructure and legislation designed to safeguard the transport access of underprivileged road users. • We study whether SAVs will facilitate or impede transport accessibility for older adults and people with disabilities. • A thematic analysis is produced based on in-depth interviews with 32 stakeholders from academia, government and advocacy organisations in Greece. • Four multi-layered themes namely infrastructure and the built environment, inclusive technology, scepticism and reality check and policy and governance define the SAV accessibility discourse. • Fixing the basic accessibility inconsistencies of an unreliable road infrastructure ecosystem and delivering SAVs as a trustworthy, affordable and user-centric technology are important. • Also, replacing scepticism with an ethos of engagement built around social awareness activities minimising safety, cybersecurity and ethics concerns and making policy and governance more flexible, citizen-centric and well-monitored will benefit older adults and people with disabilities.
  • Evaluating the road environment factors underpinning cargo bike safety and ease of movement: A sustainable urban mobility plan-driven MICMAC approach
    Ioannis Chatziioannou, Kalliopi Michalakopoulou, Stefanos Tsigdinos, Efthimios Bakogiannis, Alexandros Nikitas
    Transportation Research Part E Logistics and Transportation Review, 2026
    • Cargo bikes is an emerging but still understudied form of low-carbon urban freight transport. • This study examines how road environment factors impact cargo bike safety and ease of movement; prerequisites for their adoption and establishment as a mainstream solution. • Using MICMAC we ‘test’ the impact of bicycle infrastructure, streetlights, bike lane space, slopes, mixed cycling-walking environment, speed limits, traffic load, sharp turns, intersections, route length and road surface quality on cargo bikes. • Adequate bicycle infrastructure and street lighting are essential built environment factors for cargo bike operations. • Dedicated bike lanes, well-lit streets, low traffic areas, green routes, LEZs and UCCs are key policies aiding cargo bikes. The prioritisation of cargo bikes in urban settings is emerging as a critical strategy for transitioning to an era of sustainable urban freight transport, since they offer a low-carbon first- and last-mile alternative to traditional motorised logistics. This study identifies, contextualises and evaluates some of the key road environment factors influencing cargo bike safety (and thus adoption), using a robust, but still vastly underutilised in transport studies, semi-quantitative methodology, i.e., Structural Analysis-MICMAC. Through expert consultations, the research uncovers complex interdependencies among 11 factors, stressing the need for dedicated bike lanes, holistic urban logistics policies, and pro-cycling initiatives within Sustainable Urban Mobility Plans (SUMPs). Our findings highlight, in particular, the pivotal roles of adequate bicycle infrastructure and street lighting in encouraging cargo bike usage. The paper further aligns these factors with existing transport policies, proposing actionable recommendations like the establishment of low emission zones and urban consolidation centres. By integrating participatory methodologies with policy analysis, this work advances the understanding of cargo bikes’ urban fit and what road environment investments their broader adoption requires, so that these will contribute to the decarbonisation of our cities. Future research should explore further each of these factors to enhance decision-making frameworks for sustainable logistics planning.
  • Could connected, autonomous and digitised transport technologies improve older people's lives and sense of belonging? Evidence from a Southern European metropolis
    Stefanos Tsigdinos, Christos Karolemeas, Erika Aliaj, Efthimios Bakogiannis, Charles Musselwhite, Alexandros Nikitas
    Transportation Research Part F Traffic Psychology and Behaviour, 2026
    This study investigates whether connected, autonomous and digitised transport technologies could improve the lives of older people and strengthen their sense of belonging using as a case study, the metropolitan environment of Athens, Greece. Data was collected from 205 participants aged 60 and over via hard copy questionnaires to explore their awareness, accessibility-themed perceptions and approval of emerging transport technologies. Although participants had little familiarity with technologies such as Autonomous Vehicles, Mobility-as-a-Service, travel guidance apps, assistive and real-time information technologies, they recognised the potential benefits of improved quality of life and social inclusion. Through ordinal regression modelling we found that existing Internet usage and perceptions reflecting the possibility for increased autonomy significantly predicted positive perceptions towards these emerging transport technologies, while concerns about cybersecurity breaches, extra costs and employment market disruption emerged as significant barriers to acceptance. The results show a significant digital divide among participants, almost half of whom said they do not use the Internet and most of whom reported dissatisfaction with current institutional support for technology adoption. While connected, autonomous and digitised transport technologies hold significant potential for improving the mobility and social inclusion of older adults in Athens, realising this potential will require targeted efforts to overcome the digital divide, address safety concerns, ensure affordability and provide adequate support and training systems for technology adoption.

  • Connectivity or proximity planning in rural areas? Accessibility and equity insights from Crete, Greece
    Stefanos Tsigdinos, Olympia Kourounioti
    Journal of Rural Studies, 2026
    This study endeavours to shed light on the debate between connectivity and proximity planning in car-centric rural settings. To this end, this research will examine connectivity (new public transport lines) versus proximity (new amenities) scenarios in terms of accessibility to basic amenities and equity implications. Based on that, this research could identify policy insights for improving access to daily needs. The study area is the municipality of Amari in Crete, Greece, a remote mountainous area characterised by a prevalent reliance on cars. Delving into the method, four distinct scenarios are investigated; the first one assesses the existing condition, the second one proposes a redistribution of amenities (proximity), the third one explores the expansion of the public transport network (connectivity), and the final one considers the combined effect of new amenities and new public transport lines. Employing spatial analysis techniques and welfare economics indices, helps measure accessibility to basic amenities like supermarkets, healthcare services and public administration as well as equity conditions for households without cars in the study area. The findings demonstrate that connectivity-focused solutions enhance equity, while proximity-based strategies improve accessibility conditions. However, the most effective scenario in terms of both accessibility and equity, adopts a combinatorial approach, introducing both new amenities and new public transport lines. The study's contribution lies in its quest for key solutions tailored to rural areas, exemplified by the challenging case of Amari. Moreover, the replicability of the method, supported by an analytical methodological framework, could be helpful for policymakers and planners. • This paper explores connectivity and proximity planning scenarios in a rural area. • Spatial analysis techniques coupled with welfare economic indices are utilised. • When compared, connectivity improves equity, while proximity enhances accessibility. • Combinatorial (both connectivity and proximity) solutions achieve optimal results. • This study provides insights for planners to enhance local accessibility and equity.
  • Pedalling towards inclusion: Accessibility and equity implications for older people in future cycling scenarios for a small-sized mediterranean city
    Konstantina Damvakari, Stefanos Tsigdinos, Ioannis Chatziioannou, Efthimios Bakogiannis, Alexandros Nikitas
    Journal of Transport and Health, 2025
    Resilient cities shift from car-centric systems to sustainable transport modes, with cycling playing a pivotal role in rebranding urban mobility and supporting health and wellbeing. For small-sized cities, though, cohesive methods for planning accessibility-enabling and equity-enhancing cycling networks remain underdeveloped. In this context, this study endeavours to assess how diverse future cycling scenarios affect accessibility and equity, focusing on older people. The method followed, explored three scenarios with different cycling network configurations: the do-nothing scenario that preserves existing conditions, the formal planning scenario, stemming from the Sustainable Urban Mobility Plan (SUMP), and the “bicycle-oriented” scenario, a radical one formulated by an advanced street classification method. Accessibility levels were calculated through gravity measures, while equity implications were evaluated using indices like the Concentration Index and Bivariate Local Moran's, with a particular interest in accessibility for older people. The coastal city of Kalamata, Greece, serves as our case study, characterised by a prominent share of older people and a strong car-centric culture. Our results indicate that achieving equitable outcomes is a complex effort. Although, the bicycle-oriented scenario yielded the most critical changes and cycling accessibility benefits areas with high concentration of older people were disproportionately affected raising equity concerns. On the contrary, significantly milder changes, as shown in the formal planning scenario, led to more balanced outcomes, thus manifesting the usefulness of planning, acknowledging distributional issues. While some scenarios enhance accessibility, they may not lead to the most equitable distribution of infrastructure. There is a need for more society-centric integrated planning, attending to the special needs of certain socio-economic groups, as “universal” solutions risk exacerbating transport inequity. The paper offers insights on cycling equity for both academics and practitioners operating in similar urban contexts. • Cycling has emerged, during Covid-19, as a mainstream modal choice that is still facing access challenges having to operate in car-centric landscapes. • Using Kalamata, Greece as our case study example we test three future transport scenarios to evaluate whether cycling can be more accessible and equitable especially for older people. • The do-nothing scenario (S0), the Sustainable Urban Mobility Plan (SUMP)-based scenario (S1) and the “bicycle-oriented” scenario (S2) are proposed and compared. • S2 yielded the most accessibility benefits when it comes to facilitating better bicycling conditions but areas with high concentration of older populations were disproportionately affected raising equity issues. • Milder changes, as demonstrated by S1, brought more balanced results showcasing the importance of planning considering distributional issues and vulnerable populations.
