LAND USE AND PHYSICAL ACTIVITY

描述（由申请人提供）：鼓励身体活动的城市和郊区环境有很大的潜力预防各种疾病，特别是心血管疾病。最近的研究表明，土地利用和街道设计对人们选择步行还是骑自行车有很大的影响。由于步行和骑自行车可以显著促进健康，我们建议仔细研究土地利用与街道设计以及步行和骑自行车之间的关系。

DESCRIPTION (provided by applicant): Urban and suburban environments that encourage physical activity have great potential to prevent a variety of diseases, especially cardiovascular disease. Recent studies suggest that land use and street design strongly influence whether people choose to travel by foot or bicycle. Because walking and bicycling can significantly promote health, we propose to carefully investigate the relationship between land use and street design, and walking and bicycling. We propose to link data on land use, mainly from the US Census, with data on walking and bicycling from detailed surveys of the US Department of Transportation. Specifically, we will address to what extent the following aspects of land use are associated with walking and bicycling: street patterns; proximity of potential employers; relative diversity of socio-economic groups; proximity of destinations for personal and recreational activities; and density of the resident population. The proposed research will be among the first to identify specific features of land use that are most consistently associated with walking and bicycling. The study is intended to promote general and cardiovascular health by contributing to policy decisions concerning urban and suburban development and design.
