Use of alternative sources of transportation among older adult drivers

Driving is the preferred source of personal transportation for older adults. However, personal transportation is not limited to owning and operating a car and can be conceptualized as utilization of different modes of transportation to meet personal mobility needs. The aims of this study are to describe the types and number of alternate transport sources of transportation used by older drivers and to explore whether the distances driven by older drivers vary by their use of alternate transport. This is a cross-sectional analysis of the baseline data from the Longitudinal Research on Aging Drivers (LongROAD) cohort study, which includes healthy drivers aged 65–79 years. The results suggest that most older drivers have at least one alternate source of transportation; most commonly riding as a passenger with a friend or family member (87%). Those who reported riding as passengers (OR=0.69 [95% CI: 0.54–0.87]), riding a train (OR=0.63 [95% CI: 0.49–0.81], using a taxi/ride share (OR=0.75 [95% CI: 0.58–0.96]), or riding a bus (OR=0.75 [95% CI: 0.56–0.99]) were less likely to drive shorter distances. The odds of driving only shorter distances was significantly lower among those who reported 1, 2, or 3+ types of alternate transport sources relative to those who reported no types. Communities should consider how to improve access to alternate transport sources for older adults, so as to mitigate the adverse health and social impacts of restricting driving.
