| 摘要： | During 2001 and 2002, the SMARTRAQ research program collected data on travel behavior, physical activity and attitudes from the members of 8,069 households in the 13 county ozone non-attainment Atlanta regions. Additionally, at the same time the SMARTRAQ program also developed a regional parcel-level land use database. Together, these components allowed program investigators to study systematically the effects of land use on travel behavior, vehicle emissions and physical activity. Statistically significant inverse relationships were found for the effect of urban form (net-residential and intersection densities, mixed use) on vehicle emissions, miles and hours traveled, and obesity. The likelihood of walking and using transit was positively correlated with overall physical activity patterns. Moreover, nearly a third of the people in the Atlanta region indicated that they wanted to reside in walkable and transit-oriented communities with mix of nearby land uses. However, people in this group often had to suffice with auto-oriented communities, indicating a gap between a large market segment's development preferences and the supply of such development in the region. |
