快速城市化背景下城市区域高速公路指路标志的设置

The Guide Sign Layout of Urban Expressway under Rapid Urbanization Background

为适应快速城市化的背景下,城市区域高速公路对指路标志设置的变化和需求,论文首先分析了我国城市区域高速公路的特征及其给指路标志设置带来的问题,在总结国外先进做法和我国工程实践的基础上,提出了城市区域高速公路指路标志的设置原则和要点,并研究了互通间距较近、重合路段、互通立交指示等3种特殊情况指路标志的设置方法,最后对我国相关标准规范的制修订提出了建议.

With the rapid urbanization of China,urban expressway shows new characters,which leads to the different needs for guide sign designs from general conditions. To meet the change and demand,this paper first analyzed the characters and problems of guide sign design on urban expressway. On the basis of the advanced foreign and domestic engineering practices,the principle and key point of guide sign design was proposed for urban expressway. The new design methods were then used in three special cases,which featured closely-spaced interchanges,overlapping routes and interchange guide. Finally,a few recommendations were proposed for the setting or revision of standards and specifications.
