对保腾高速公路创新设计的道路雾区标志、半月状车距确认标线、道路能见度标志三类引导设施的应用背景、设计要求、综合应用效果进行了论述。结果表明:国内外山区公路雨雾气候条件下系统性引导尚不成熟;新型道路雾区标志、半月状车距确认标线、道路能见度标志可以综合协同发挥引导效果,提高行车安全。 This paper discusses the application background, design requirements and comprehensive application effects of innovative design road fog zone logo, half-moon-like vehicle alignment mark and road visibility sign of Baoding Expressway. The results show that systematic guidance is not yet mature under the conditions of rainy and fog in the mountainous areas both at home and abroad. The marking of the new type of road fog area, the confirmation mark of the half-moon-shaped vehicle distance and the road visibility sign can play a guiding role in the overall synergy and improve traffic safety.
