Transportation Behavior Among Older Vietnamese Immigrants in the Dallas-Fort Worth Metroplex

Rebecca Mauldin Stephen Mattingly , Rupal Parekh
Nearly 4.6 million immigrants age 65 years and older live in the United States. This population is expected to more than triple in size by 2050. A lack of culturally appropriate transportation solutions for older immigrants and migrants (i.e., (im)migrants) creates disparities in access to services for older (im)migrant populations, increasing their risk of social isolation and reduced physical and mental health. Transportation disparities also have negative ripple effects to other sectors… Read More

Incorporating Bicycle Activity and Vehicle Travel Reduction from Bicycle Infrastructure into Strategic Planning Tools

Planners and modelers at all levels of government have been grappling with the problem of how to better represent bicycling when modeling and forecasting future scenarios. Planners want to know how and to what extent infrastructure projects can increase bicycling activity and reduce the health, environmental, and financial burdens imposed by single-occupant vehicle travel. This technical transfer report describes the development of an extension to existing tools that allows strategic assessment… Read More
