摘要：支路正如人体的毛细血管，在城市交通中起着重要作用。但是目前国内对支路的规划设计一直重视不够。首先总结了支路发展中存在的功能划分、密度和横断面布置等问题，详细分析了支路在城市交通中的功能。结合国外城市道路功能划分，将支路划分为交通性支路、生活性支路和特殊支路，分析了不同支路承担的具体作用和适应范围。并针对支路网的密度、红线宽度、车道宽度、分隔设置以及路边停车问题进行了深入分析。

Abstract: Local roads play an important role in urban street systems, just like capillaries do in human bodies. However, local roads have not gained sufficient attention thus far in the planning and design process of urban street systems in China. This paper discusses issues on road functional classifications, road network density, and cross-sectional design in local road development, and provides a detailed analysis of local road functionalities. According to road functional classifications typically adopted abroad, the paper classifies local roads into three functionalities, namely, through-traffic, neighborhood-specific, and special use, and specifies their typical functions and application scopes. Finally, the paper further analyzes local road density, right-of-way, lane-width, separation facilities, and road-side parking issues.

Keywords: local road planning; local road design; local road functionalities
