Resumen
Residents in small urban and rural areas frequently depend on unreliable personal transportation to maintain their lifestyle and get to essential destinations within their society. Especially, vulnerable populations, such as seniors and low-income residents, have lower access to personal vehicles and therefore are mobility-challenged. Being challenged in terms of mobility has effects on the health of the population concerned as this constraint not only limits economic activity that leads to perpetuation of lower means and poverty but also social activity that leads to physical and mental isolation. In a study of Michigan public and nonprofit transit systems, the customer satisfaction, particularly of vulnerable populations, with transit services is analyzed through on-board intercept surveys. Results illustrate the significance of employment, age, income, disability, and demand-response services in public transit planning and ultimately public health.
