历史城区道路等级划分方法研究——以福建省长汀古城为例

历史城区内的道路系统普遍狭窄且非机动交通较多,在保护历史城区道路格局时,现有城市道路等级规划标准显得较为粗泛和缺失,因此需要研究针对历史城区的道路等级划分方法。首先分析总结相关研究和国内外规划实践。提出历史城区道路等级划分需要考虑的主要要素:交通功能、历史格局、街道功能等。以福建省长汀古城为例,采用统计断面人流量、道路城市功能分类等方法,梳理分析其道路网的特点。将古城内外道路划分为五个等级,其中适当增加适应历史城区的主要街巷、次要街巷等级。规划评价结果显示,路网结构和密度较为合理,有利于路网发挥协同分工作用。

Roadway Classification in Historic Urban Areas:A Case Study of Changting Old Town in Fujian Province

The roadway network in historic urban areas is generally narrow and dominated by non-motor-ized traffic. Due to the existing specifications of roadway classification are insufficient in street preserva-tion, it is necessary to study on the road classification system for historic urban areas. This paper summariz-es the main elements of roadway classification in historic urban areas, including transportation functional-ities, historical patterns, and street functionalities. Taking Changting old town in Fujian Province as an ex-ample, the paper analyzes the characteristics of roadway network through investigating pedestrian flow and roadway functionalities categorization. The roadway network is categorized into five classes, which in-crease the class of major alley and minor alley in historic urban areas. The assessment results show that roadway pattern and density are applicable on functionalities division and coordination.
