| 示警桩是指警告道路前方有危险路段的反光标桩。城市的次干路、支路未设交通信号灯的平面交叉路处前方，树立红、白两色相间反光性标柱，其外径约9cm，高80〜100cm。目的是向机动车驾驶员提示前方有交叉口、急弯、狭路等，提高警惕以策安全。 Warning piles refer to reflective cursor piles warning dangerous sections in front of the road. In front of the plane intersection of the city's sub-trunk roads and branches without traffic lights, a red and white reflective pillar with an outer diameter of about 9 cm and a height of 80 100 cm is set up. The purpose is to alert motorists that there are intersections, sharp bends and narrow roads ahead, so as to enhance their vigilance for safety. 我国低等级公路(设计速度40km/h以下)通车里程约占公路总里程的88%,共计391.8万km。由于低等级公路量大面广,而公路建设养护资金又不够充足,因此在低等级公路交通安全改善工程中隐患点的处置优先考虑标志、标线、示警桩等主动引导设施,并且提倡因地制宜应用施工便利、建设养护成本较低的设施。警示桩因造价低,施工养护方便,成为我国低等级公路应用最广泛的主动引导设施。示警桩尽管应用多年,却没有相关研究对其使用效果和设置方法进行分析与总结。凭借经验设置的示警桩或许存在着安全问题和需要优化的方面。 The opening mileage of low-grade highways (below 40 km/h in design) in China accounts for 88% of the total mileage of highways, totaling 3.918 million km. Because of the large volume and wide range of low-grade highways and insufficient funds for highway construction and maintenance, active guiding facilities such as signs, markings and warning piles should be given priority in dealing with hidden dangers in the improvement project of traffic safety of low-grade highways, and facilities with convenient construction and low maintenance cost should be advocated according to local conditions. Because of its low cost and convenient construction and maintenance, warning piles have become the most widely used active guiding facilities for low-grade highways in China. Although warning piles have been used for many years, there is no relevant research to analyze and summarize their use effect and setting methods. The warning piles set by experience may have safety problems and need to be optimized. |
