新城市主义、交通导向发展和新传统规划等流行而有影响力的规划运动的主要吸引力在于它们假定的交通效益。尽管提倡这些想法的建筑师和规划者通常都小心翼翼地强调获得预期结果所必需的许多因素——理直街道以开放当地网络，“平静”交通，更好地整合土地使用和密度，等等——但越来越多的文献和计划实际上将这些因素的任何组合都视为不言自明的改进。潜在的问题是，新计划对交通的影响通常是不确定的，也不清楚设计者是否充分了解其中的原因，以避免意想不到的结果。本文提出了一个简单的行为模型来识别和评估这些想法对交通和细分规划者施加的权衡。
A major attraction of the popular and influential planning movements known as the new urbanism, transit-oriented development, and neotraditional planning are their presumed transportation benefits. Though the architects and planners promoting these ideas are usually careful to emphasize the many ingredients necessary to obtain desired results-straightening of streets to open the local network, ''calming'' of traffic, better integration of land uses and densities, and so on--a growing literature and number of plans feature virtually any combination of these elements as axiomatic improvements.The potential problem is that the traffic impacts of the new plans are generally indeterminate, and it is unclear whether designers understand the reasons well enough to avoid unintended results. This paper proposes a simple behavioral model to identify and assess the tradeoffs these ideas impose on transportation and subdivision planners.
