Assessing mobility in an aging society: Personal and built environment factors associated with older people’s subjective transportation deficiency in the US

This study analyzed subjective transportation deficiency, in terms of missing activities due to lack of transportation, of the older population aged 65 and over in the United States. This study found that those who have lower personal automobile accessibility and minority females are more likely to experience transportation deficiency. Older people who have lower income, have lived for a relatively short period (3–10 years) in their communities, and live with minors are also more likely to experience lack of transportation. Older people who live in suburban communities have greater transportation deficiency, but the placement of activity locations within walking distance can improve transportation deficiency among older people who do not drive. The availability of public transit services within walking distance and knowledge about transportation alternatives do not significantly affect the transportation deficiency of the older population. The results indicate that a substantive focus should be given to how to help the older population keep driving as long as they can, and aid communities with high concentrations of older minority females. Also, developing activity clusters containing commercial and social service facilities in suburban areas with high concentrations of older populations, has the potential to alleviate transportation deficiency among this widely observed group of people who age in place.
