高速公路特殊路段交通标志布设优化研究

充分尊重高速公路及所在路网的道路条件、运营环境，结合国内外相关科技技术成果，主要针对高速公路交通安全设施施工图设计中存在的典型问题．分系统逐桩号进行高速公路标志的核查及优化，并以此为基础，提出一套可行、实用的高速公路交通标志设计优化流程与方法．有针对性地对特殊重点路段的警告、禁令、告示、服务区和辅助等各类标志的设置位置及数量等进行优化．可在交通标志设计环节中最大程度地减少安全隐患。

Design Optimization of Traffic Signs for Special Sections of Expressway

This paper fully respects road conditions and operation environment of expressway and the road network, focuses on examination and optimization of traffic safety signs and discusses the readability, timeliness and effectiveness of traffic sign. Firstly, a set of feasible and practical processes and methods of design optimiza- tion of traffic signs on expressways based on domestic and foreign related scientific and technological achieve- ments are proposed. Then, the set position and quantity of various signs such as warning, prohibition, notice, ser- vice area and auxiliary signs in special and key sections are pertinently optimized. The whole optimization work can transforms safe guard into design guard to minimize potential security risks in the design process of traffic signs.
