新城市主义者倡导使用方格路网来替代曲线型尽端路网,以期增加道路的连通性来促进社区的慢行交通。本文选取美国得克萨斯州的3个居住区,运用GIS工具测量可促进慢行交通出行的5个指标,发现方格路网虽然在街道连通性和可达性方面具有优势,但如果不重视土地的混合利用及慢行交通基础设施建设,方格路网并不能促进居民选择慢行交通出行。我国需吸取美国郊区化建设的教训,应在宏观土地利用、交通结构和公共政策等方面促进可持续的交通出行方式。 New Urbanists advocate the use of grid roads instead of curvilinear end-use networks to increase road connectivity to facilitate slow traffic in the community. In this paper, we select three residential areas in Texas, USA and use GIS tools to measure five indicators that can promote slow-moving traffic. It is found that although the grid has advantages in street connectivity and reachability, Mixed use and slow traffic infrastructure construction, grid road network and can not promote residents to choose slow traffic travel. China needs to learn from the lessons of suburbanization in the United States and promote sustainable modes of transport and travel in the fields of macroscopic land use, traffic structure and public policies.
