全球城市街道网络设计与交通相关温室气体排放

Urban Street Network Design and Transport-Related Greenhouse Gas Emissions around the World

Geoff Boeing, Clemens Pilgram, Yougeng Lu

AI总结:

本研究基于全球城市样本,发现更直、更连通且过度建设更少的街道网络与更低的交通CO2排放相关,且该关系因发展水平和设计范式而异,为全球南方等研究不足地区提供了经验基础。

摘要:

本研究估算了全球每个城市地区的街道网络特征与交通部门CO2排放之间的关系,并调查了这些关系在不同发展水平和城市设计范式之间是否相同。先前的文献主要通过聚焦于特定世界区域或相对较小的城市样本的案例研究,估算了街道网络设计与交通排放(包括与气候变化有关的温室气体)之间的关系,这使证据知情实践的一般适用性和适用性变得复杂。我们的全球研究发现,在其他条件相同的情况下,更直、更连通且过度建设更少的街道网络与更低的交通排放相关。重要的是,这些关系在不同发展水平和设计范式之间各不相同——然而,大多数先前的文献报告了来自按全球标准属于异常值的城市地区的发现。规划者需要为研究不足的地区(特别是快速城市化的全球南方)的证据知情实践提供更好的经验基础。

英文摘要:

This study estimates the relationships between street network characteristics and transport-sector CO2 emissions across every urban area in the world and investigates whether they are the same across development levels and urban design paradigms. The prior literature has estimated relationships between street network design and transport emissions -- including greenhouse gases implicated in climate change -- primarily through case studies focusing on certain world regions or relatively small samples of cities, complicating generalizability and applicability for evidence-informed practice. Our worldwide study finds that straighter, more-connected, and less-overbuilt street networks are associated with lower transport emissions, all else equal. Importantly, these relationships vary across development levels and design paradigms -- yet most prior literature reports findings from urban areas that are outliers by global standards. Planners need a better empirical base for evidence-informed practice in under-studied regions, particularly the rapidly urbanizing Global South.
