步行和自行车交通系统层次化网络构建方法--以海南省三亚市为例

针对步行和自行车交通网络规划缺乏系统方法的情况，以《城市步行和自行车交通系统规划设计导则》编制研究为基础，从使用者意愿角度出发，提出以步行和自行车交通分区、步行和自行车道路分级为核心的层次化网络构建方法。采用定性与定量相结合的方法划定分区，以契合政策导向和设施供给的双重属性；根据步行和自行车出行特点差异，提出契合城市空间结构和用地布局的差异化布局模式；给出步行和自行车道密度、宽度指标，以及在空间、环境、衔接层面的设计指引。强调在相关规划中落实控制指标，以保障步行和自行车交通系统层次化网络的构建。

Developing a Hierarchical System for Pedestrian and Bicycle Transportation:An Example in San-ya,Hainan

Concerning the lack of a systematic approach for pedestrian and bicycle transportation planning in China, this paper proposes a hierarchical system planning method based on the development of Guide-line for Urban Pedestrian and Bicycle Transportation System Planning, which considers users' need and re-quirement. This method focuses on transportation zoning and roadway classification for pedestrian and bi-cycle transportation system. The zoning is determined by both qualitative and quantitative analyses in or-der to meet demands of both policy guided development trend and facilities supply. Recognizing the differ-ence of travel characteristics between walking and bicycling, the paper proposes a differential layout mod-el, which coordinates with the urban spatial structure and land use development. The design features, such as density and width of pedestrian walkway/bicycle lane, and guideline on design elements' context sensi-tive connection with local environment are presented. Finally, the paper stresses the control criteria imple-mentation in the planning, which ensures the development of a hierarchical transportation system for pedes-trian and bicycle.
