OVERVIEW

Mobility disparities among older adults affect their ability to travel and access services. This project seeks to understand challenges, barriers, and gaps that older adults experience and to develop forms of assistance or educational strategies to fill the varying mobility gaps and meet the mobility needs. This study characterizes older adults’ use of existing and potential transportation options, including conventional transit, paratransit, and ride-hailing systems, based on surveys and interviews collected from community-dwelling older adults in Dallas, Texas. Through the interview during the pandemic, the research team found that perceptual and knowledge barriers appear to be reduced among older adults to adopt new mobility options such as ride-hailing although financial and technology barriers still exist. Based on the findings, we discussed several strategies that can...

OVERVIEW

Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes.

Recently, new sources of bicycling activity data have emerged such as Strava, Streetlight, and GPS-enabled bike share systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has been questioned, and their suitability for producing bicycle volume estimates has yet to...

WEBINAR VIDEO

This webinar will explain how app-based technologies can improve upon traditional pen-and-paper-based daily transportation diaries in terms of quantity and quality of data collected, particularly for environmental justice populations. The researchers will describe their own efforts, working on an inter-disciplinary team, to develop a custom-designed app, MyAmble, that measures the impact of transportation disadvantage more broadly across access to basic resources, opportunity to participate in wider society, and quality of life. MyAmble includes several innovations – daily digital trip planning, a text-messaging-based qualitative interview tool, and a challenge logger enabling participants to document real-time transportation barriers through videos and photos. Viewers will learn pragmatic strategies for implementing similar app-based ecological momentary assessment transportation data collection tools. In addition, researchers will share lessons learned from working on a technology-based interdisciplinary team.

OVERVIEW

Drawing from the framework of social determinants of health, the objective of this study is to investigate the cross-sectional association between transportation-related factors and self-perceived physical health among adults in the U.S.

Data for this study were derived from the 2017 National Household Travel Survey. An analytic sample of 71,235 respondents aged 18 and 64 years was analyzed using binary logistic regression. Of the 71,235 respondents examined, 8.9% perceived their physical health to be poor. About 36% of the respondents had fewer vehicles per individuals in the household.

Controlling for the effects of other factors, respondents who had fewer vehicles per individuals in the household were 1.27 times more likely to report poor self-perceived physical health when compared to their counterparts with more vehicles per individuals in the household (AOR=1.27, 95% CI=1.17-1...
