Journal ArticleDOI
Mobile device data reveal the dynamics in a positive relationship between human mobility and COVID-19 infections.
TL;DR: It is found that external travel to other counties decreased by 35% soon after the nation entered the emergency situation, but recovered rapidly during the partial reopening phase, and the dynamics in a positive relationship between mobility inflow and the number of infections during the COVID-19 onset are highlighted.
Journal ArticleDOI
How do built-environment factors affect travel behavior? A spatial analysis at different geographic scales
Jinhyun Hong,Qing Shen,Lei Zhang +2 more
TL;DR: The research employs Bayesian hierarchical models with built-environment factors measured at different geographic scales and indicates that land use factors have highly significant effects on VMT even after controlling for travel attitude and spatial autocorrelation.
Journal ArticleDOI
The analysis of transit-oriented development (TOD) in Washington, D.C. and Baltimore metropolitan areas
Arefeh Nasri,Lei Zhang +1 more
TL;DR: In this paper, the authors tried to understand how travel behavior is different for transit-oriented development (TOD) residents in the two metropolitan areas of Washington, D.C. and Baltimore.
Journal ArticleDOI
How built environment affects travel behavior: A comparative analysis of the connections between land use and vehicle miles traveled in US cities
TL;DR: In this article, the authors examined the effects of built environment factors on travel behavior, in particular VMT in five U.S. metropolitan areas grouped into four case study areas, and found that promoting compact, mixed-use, small-block and infill developments can be effective in reducing VMT per person.
Journal ArticleDOI
Human mobility trends during the early stage of the COVID-19 pandemic in the United States.
TL;DR: The study suggests that the public mobility trends conform with the government message urging to stay home, and offers integrated perspectives and serves as evidence to raise public awareness and reinforce the importance of social distancing while assisting policymakers.
