城市道路分级体系及相关因素研究

城市交通的发展对于道路等级体系划分提出了新的要求，而不同等级道路的差异最终取决于一系列因素的不同。本文以满足城市居民不断发展的多样化交通出行需求、实现道路的多重功能为目标，对道路等级及其相关因素进行研究。提出将道路等级相关因素归纳为管理因素与物理因素，并详细研究了各因素的取值标准，最后提出了四级九类的道路等级体系。以武汉市为例，介绍了上述道路等级体系在指导城市道路交通系统规划中的合理性和实用性。

Study on Urban Road Hierarchy and Related Factors

The development of the urban transport has proposed new requirements for the division of road grade system, the differences of the different road levels ultimately depend on a number of different factors. In this paper, the road grade and related factors has been studied to meet the needs of urban residents＇ continuous increase transportation, and to achieve the multiple function goal of the road. The relevant factors of road grade have grouped into management and physical factors, and a detailed study on choosing the value standards of the relevant factors has been made. Based on the above, a 4 levels and 9 categories of road system were proposed. Taking Wuhan City as an example, this paper has proved that it is reasonable and practical to use the road grade in guiding the planning of urban transport system
