Abstract: Referring to national standards and related rules and norms as well as the previous study, the paper discusses the analysis and evaluation of urban road guide signs sets. It presents the analysis and evaluation norm of urban road guide signs set, based on abovementioned norms, proposes several evaluation indexes about urban road guide signs set, such as guide information overload rate, various types of identification information rate, guide information classification rate, intersection road guide signs coverage rate, and so on. And then, it takes Zhujiang New Town’s trunk road network in Guangzhou province of China as a example. Based on the present road guide signs data, it calculates the evaluation indexes values, refers to the relevant standards and experience knowledge and fits with the actual situation. The results indicate that the guide signs of Zhujiang new town are basically reasonable.

摘要： 参照国家标准、相关规则规范及前人研究成果，对城市道路指路标志设置的分析和评价方法进行了探讨，首先给出城市道路指路标志设置的分析评价准则，基于准则提出指引信息过载率、各类指示信息的比率、指示信息分级比例、路口指路标志覆盖率等评价指标的计算公式及各变量含义.最后，笔者以广州市珠江新城主干路网为例，在其现有指路标志数据的基础上，计算上述各评价指标值，参照相关标准和经验知识，结合实际情况进行分析评价，得出珠江新城主干路网的指路标志设置基本合理.
