摘要：Physical activity (PA) promotes healthy life and contributes to sustainable development. In this paper, we rely on the Utah Household Travel Survey data and analyze the determinants of PA in terms of neighborhood land use, accessibility to transportation, and socio-demographic status in Salt Lake County, Utah, United States using four-component walkability indices at various geographic scales. We find that PA is associated with neighborhood land use and social demographic status, including the compact design of the neighborhood. The results also indicate that land use mix is insignificant, and that current neighborhood design only supports peopleâ€™s 20-min walk. The spatial lag model reveals significant spatial autocorrelation of PA but the barely improved R 2 validates the dominant effect of neighborhood land use and social demographic status on peopleâ€™s walking behavior.
