There has been considerable interest in the impact that the built environment has on vehicle miles traveled (VMT). While this issue has been extensively researched, due to the heavy reliance on cross-sectional data, there remains uncertainty regarding how effective local land-use planning and regulation might be in reducing VMT. Based on a 13-year panel of Florida counties, models are estimated that relate VMT to new measures of the spatial distribution of alternative land uses within counties and county urban expansion. Identification of causal effects is established by including year and county fixed effects, along with an extensive set of control variables, and instrumenting those land uses that may be endogenous. Incremental annual changes in the spatial concentration of alternative land uses are found to affect VMT. The policy implication is that appropriate land-use policy can reduce VMT and should be considered part of the strategy for dealing with the problem of global warming.

行驶里程和建筑环境：面板数据的新证据

人们对建筑环境对行驶的车辆行驶距离（VMT）的影响引起了极大的兴趣。尽管对此问题进行了广泛的研究，但由于严重依赖横截面数据，因此尚不确定当地有效的土地利用规划和法规在减少VMT方面的有效性。根据佛罗里达州一个为期13年的小组讨论，估算出一些模型，这些模型将VMT与各县和县城扩展中替代土地利用的空间分布的新度量联系起来。通过包括年和县固定效应以及广泛的控制变量，并对可能是内生的土地利用进行测量，可以确定因果效应。发现替代土地利用的空间集中度的年度递增变化会影响VMT。
