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

Urban Transportation System Flood Vulnerability Assessment with Special Reference to Low Income and Minority Neighborhoods

Courtney Crosson
Short-term flooding from extreme storm events poses a serious transportation challenge in U.S. cities. This problem—which is anticipated to grow over the next century with our global climate crisis—is often hardest on vulnerable populations, including low-income and minority neighborhoods. The latest report from the National Institute for Transportation and Communities (NITC), led by Courtney Crosson of University of Arizona (UA), advances national research methods for assessing flood… Read More
