| 摘 要： | 目前《公路路线设计规范》（JTG D20-2006）与《公路项目安全性评价指南》（JTG/TB05-2004）对停车视距的规定存在较大差异,鉴于此,如何设计出既能保证行车安全又经济合理的良好线形,是一个值得讨论的问题。通过对停车视距机理及视距与曲线半径关系的分析,深入阐述高速公路停车视距问题并提出一些针对性的措施,可供同行参考。

| Abstract: | There is difference about the stopping sight distance of expressway between Design Specification for Highway Alignment（JTG D20-2006） and Guidelines for Safety Audit of Highway（JTG/T B05-2004）.Given this,it is worth discussing how to design safe and economical and reasonable line.The principles and the relationship between sight distance and radius of curve are analyzed to elaborate the stopping sight distance on expressway and propose the relating measures,which would provide reference for technicians. |

| Keywords: | expressway vehicle speed friction coefficient stopping sight distance radius of curve |
