【摘要】：特殊的空间形态、稀缺的贯通性轴向道路资源以及高度混合的内外交通导致带型城市面临独特的交通问题。从城市空间形态角度出发,采用聚类分析法分析中国657个设市城市,据此界定带型城市为建成区长宽比大于3的城市。并对带型城市(组团)的交通需求、路网布局、道路级配进行梳理,发现带型城市贯穿性长轴干线道路的数量、等级、分布对带型城市规模、形态以及交通组织具有重要作用,是带型城市路网规划的核心。最后,提出带型城市常用的三轴干线路网布局模式及相应的道路等级,可作为带型城市路网规划的参考依据。
[Abstract]:Special spatial form, scarce axial road resources and highly mixed internal and external traffic lead to unique traffic problems for belt cities. From the perspective of urban spatial form, the cluster analysis method is used to analyze 657 cities in China. The paper defines the belt city as the city whose aspect ratio is greater than 3, and combs the traffic demand, road network layout and road gradation of the belt city, and finds out the number and grade of the long axis trunk road in the belt city. Distribution plays an important role in the scale, form and traffic organization of the belt city, and is the core of the road network planning of the belt city. Finally, the layout mode of the three axis trunk network and the corresponding road grade are put forward. It can be used as a reference for the planning of urban road network.
