The loss of bus services meant people could not reach their usual range of destinations, travelled less often, and felt a sense of entrapment in their homes. They missed healthcare appointments, social interactions, and were restricted to more localised services. People experienced a loss of freedom, independence, and control over their lives. The impacts fell disproportionately on people with existing social or economic disadvantages.</div></div><div><h3>Conclusions</h3><div>Older people described harmful consequences for their physical, mental, and social wellbeing. Impacts were unequally distributed and exacerbated underlying inequalities. Buses play a vital role in supporting health and wellbeing, enabling independence, and addressing inequalities. This research adds evidence for transport policymakers to support the social wellbeing case for improving public transport.</div></div>","PeriodicalId":47838,"journal":{"name":"Journal of Transport & Health","volume":"44 ","pages":"Article 102104"},"PeriodicalIF":3.2,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
