The Association between Public Transportation and Social Isolation in Older Adults: A Scoping Review of the Literature.

Inadequate public transportation was recognized as a barrier to social participation, especially for older adults in rural communities and with mobility issues. Older adults will not benefit from opportunities to engage with their community and maintain social networks if they are unable to access them. The purpose of this scoping review was to make recommendations for further research and to summarize areas for improvement identified in the literature that will aid in the development of public transportation initiatives that can better address social isolation for older adults (≥ 55 years of age). Nineteen articles met the inclusion criteria, identifying themes of access to rural public transportation, issues with public transportation, and mobility. In practice, older adults need to prepare for driving cessation and mobility transitions; sound policy requires input to tailor transportation initiatives to an aging population, and future research should explore older adults' transportation needs and potential solutions in urban and rural communities.
