Qualitative interviews were conducted with 65 minibus and taxi drivers across urban Ghana, selected purposively to capture a diverse age range (30–65 years). Thematic analysis reveals three key findings on how occupational precarity shapes retirement strategies. First, workers develop hybrid financial systems that combine vehicle asset liquidation, informal savings (susu), and intergenerational support—strategies that treat vehicles as retirement assets, with implications for fleet sustainability. Second, while most drivers enroll in national health insurance, they neglect mental health and disability planning, exposing gaps in occupational health provisions for aging transport workers. Third, deep institutional distrust fosters a preference for self-managed solutions over formal pensions, challenging policymakers to design transport-sector-specific social protection mechanisms. The concept of “negotiated social protection” is introduced to explain how workers blend security strategies, suggesting asset-based welfare products and union-led pension schemes that harness existing trust. The study contributes to transportation research by examining the human dimensions of transport systems often overlooked in infrastructure-focused scholarship—specifically, the life-course trajectories and social protection needs of the workers who sustain informal transport networks in low- and middle-income countries. The study bridges transport research, labor geography, and social policy by highlighting the intersection of aging and precarity in the informal transport sector. The findings call for rethinking retirement policies for informal transport workers, demonstrating that the welfare of aging workers is integral to sustainable urban transport systems that serve millions across cities in the Global South.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"38 ","pages":"Article 102106"},"PeriodicalIF":4.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148476597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that these correlates are spatially heterogeneous and scale-dependent. Fine-grained street connectivity and human-scale street greenery are associated with stronger metro-integrated cycling, while development intensity exhibits a double-edged role by generating demand but also intensifying station-front friction. Employment-related destinations also differ functionally: general workplaces tend to be positively associated with integration, whereas high-end office clusters are more likely to suppress it in some areas. A practitioner interview is used as contextual triangulation to support the interpretation of these spatial patterns and their governance implications.

Pop-up bike lanes became the latest representation of the sustainable transport paradigm. But in Helsinki, despite its previous transport innovations, this new policy trend remained absent. This article explores this paradoxical absence from two double perspectives: epistemic (empirical / theoretical) and disciplinary (within / outside transport research). Organizational studies are chosen as a suitable complementary discipline to transport research to explore this case study. It is operationalized combining a bottom-up, empirical, approach (stakeholders’ interviews) and a top-down, theoretical approach (finding fitting models from both disciplines: the <em>experiential model</em> in transport history and the <em>paradox theory</em> in management). The results reveal two contradictions: technical (double standards between cycling and automobility) and political (organizational contradiction between departments). This explains Helsinki’s apparent paradox as the outcome of a double learning process. Within transport, cycling learns from automobility (strategy of “cycling highways”) and within the organization, planners learn to manage the contradictions of sustainability (without resolving them). The findings are synthetized as suggesting a new hypothesis for the current trend of transport change as “involution within unsustainability”. The article thus advances interdisciplinary transportation research by combining theoretical perspectives from Organizational Studies and Sustainability Science with the empirical study of a specific transport policy case-study. Its takeaways may be used by transportation practitioners to overcome self-reinforcing cycles of organizational learning that support the status quo of automobility and unsustainable mobility in general.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"38 ","pages":"Article 102122"},"PeriodicalIF":4.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148476692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Perhaps the most important issue is to determine the causes of this phenomenon. We address here the scientific/physiological question of whether unintended accelerations (when the intention and need was to brake) could be a direct consequence of the sensorimotor functional impairment induced by diabetic peripheral neuropathy (DPN). We studied both measures of sensory and motor function, and observations in a driving simulation, in drivers with and without neuropathy affecting sensation in the feet and proprioception around the ankle. Only drivers with neuropathy exhibited sudden, powerful, unsafe and unintended accelerations when braking was needed − instances of pedal confusion and misapplication. We argue that this difference between drivers with versus without neuropathy demonstrates that DPN could be a direct cause of these dangerous events, and propose a candidate causal mechanism. Our purpose is firstly to highlight that DPN increases the likelihood of making a mistake by pressing the wrong pedal, which places drivers with DPN at increased risk of crash as a consequence of unintended acceleration. This means, secondly, that these drivers will benefit from specific preventive countermeasures, and we recommend three that could be used: 1) choosing to drive a manual gear change vehicle rather than an automatic, 2) fitting an acceleration limiter, and 3) providing footwell illumination of the right foot and pedals during driving at night.</div></div>","PeriodicalId":36621,"journal":{"name":"Transportation Research Interdisciplinary Perspectives","volume":"38 ","pages":"Article 102129"},"PeriodicalIF":4.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148476787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This results in growing competition for the remaining space from curbside users including freight vehicles, ride-hailing services, and private cars.

Internet of Things (IoT) technologies promise real-time, fine-grained monitoring of curbside activities to enforce curbside interventions. But many pilot projects have struggled to achieve lasting success, as their designs overlooked key organizational and user-related factors. Building on the information systems success model, our study examines how cities can leverage IoT technologies to enhance curbside management. Drawing on 44 international projects and expert interviews, we conduct a morphological analysis that identifies nine design dimensions and 26 distinct design configurations. From these, five Critical Success Factors (CSFs) emerge. For information quality, we identify as CSFs (1) accurate parking durations, (2) accurate parking positions, and (3) information completeness. For system quality we find (4) ease of use, ease of learning, intuitiveness, and flexibility, and (5) privacy. The CSFs highlight a need for an enforcement focus in information quality, while system quality must ensure curbside user buy-in. We discuss further conflicts that emerge from different stakeholder objectives in user-centered designs of digital public services. Through this, we advance the theoretical understanding of information systems success in government-citizen interactions.
