Abstract
This study used a mixed-method design to examine travel behavior and accessibility of older adults. The research team conducted a statewide survey and focus groups to gather travel behavior data of older adults (50+) residing in Utah. The study also employed a two-step floating catchment area method, a novel spatial technique, and integrated the survey data to accurately measure travel accessibility of older adults. Using the survey data of 724 older adults as well as the focus group interviews of 18 older individuals, we found a significant dissatisfaction and vulnerability experienced by older adults with limited mobility. The distribution patterns of accessibility revealed communities with limited options for specific types of facilities, highlighting the need for addressing equitable access to different destinations. The study identified a positive relationship between travel frequency and satisfaction up to a certain threshold, beyond which satisfaction declined. Further investigation is needed to explore this threshold, considering health related issues and travel fatigue. Lastly, the study emphasized the importance of considering diverse dimensions of older adults' needs and developing distinct accessibility measures for underrepresented groups, such as those with low income, disabilities, and older adults experiencing mobility limitations. The findings highlight the need for policymakers to address the critical accessibility and mobility gaps and improve travel experiences for older adults.
