新城道路横断面规划设计——以宁波市东钱湖新城为例

摘要

合理规划设计城市道路横断面不仅可以提高交通运行效率,而且对塑造富有特色的城市街道空间至关重要.首先指出城市道路横断面规划设计存在的问题是局限于道路红线范围和道路工程设计,并且缺乏灵活性.以宁波市东钱湖新城为例,深入研究如何针对不同功能、不同区位的城市道路,选择满足多样性需求的道路横断面型式.宏观理念层面,基于新城规划建设目标确定横断面规划设计特色；中观分析层面,探讨城市道路的交通、生活、游憩功能；微观操作层面,分析街道空间不同行为主体的特征和关系处理.最后,总结新城道路横断面特色,并给出道路横断面规划设计示例.%Effective roadway cross-section design can not only improve traffic flow efficiency but also help to develop roadways that reflect the unique characteristic of the city. This paper first points out that the existing urban roadway cross-section design often focus on the space within the right-of-way and engineering design lack of context flexibility. Taking Dongqian Lake New Town in Ningbo as an example, the paper discusses different types of cross-section for roadways with different functionalities at various locations. The paper elaborates the roadway cross-section design in the New Town in three aspects: identifying the characteristics of road cross-section design based on urban planning and construction objectives at macro level, discussing the traffic, residential and recreational function of urban roadway at interim level, and analyzing the characteristics and relationship of different types of roadway users at micro level. Finally, the paper summarizes the characteristics of roadway cross-section and presents the typical roadway cross-section design in the new town.
