公路指路标志系统的改进研究

通过对比分析美国、日本、中国指路标志系统的特点，针对公路指路标志在交叉点和路段中的版面形式、设置位置、指示内容侧重点等问题进行研究，提炼出国外指路标志系统值得借鉴之处。从指路标志的识认性、系统性出发，建议国内指路标志系统设置作如下改进：进行地名分级、加强道路编号工作、完善指路标志图形化、明确标志形式适用性，确定交叉点、路段中指路标志设置的系统要求。希望能为道路交通标志的设计、施工提供指导，为标准修订提供参考。

Study On the Improvement of Highway Guide Sign System

A well highway guide sign system could help road users to arrive their destinations easily. The major problems of current guide sign setting are disunity in form, inconsistent between highways, and generally insufficient.The main reason is that the sigu-setting standard is lack of details. Referring to the relative rules of USA and Japan, some suggestions on improvement of sign setting in China are proposed. In order to increase the function of the guide sign system, measures of improvement should be focused on place name hierarehy,route numbering, sign graphic, etc.The result of this study can be used to amend the traffic sig~ standard and as a reference for the concerned design and construction department to update future principles of guide signs setting.
