基于安全的公路功能分类探讨

公路功能分类和通行能力直接相关,干线公路要保证大通行能力,地方公路要便利,集散公路既要有一定的通行能力又要有一定的便利性,不同功能的公路的设计特征因此而有所不同。不同公路功能分类的公路设计特征、交通特征不同,其安全性也必然不同。我国公路考虑安全如何进行功能分类?本文通过归纳、总结国内外在公路功能分类、公路设计、公路安全计划等方面的实践经验以及相关研究成果,初步分析了我国公路分类存在的问题,探讨了公路功能分类和安全的关系,提出我国考虑交通安全的理想的公路功能分类,以及相关的研究、工作的建议。

Highway Functional Classification Based on Traffic Safety

Functional classification is related to capacity directly.Arterials emphasize a high level of mobility for through movement.Local facilities emphasize the land access function.Collectors offer a compromise between both functions.The characteristics of highways are dif- ferent due to different functions.The features of the highway and the traffic volume are various,so the safety performance are differ- ent.How to functional classify highways of China concerning traffic safety?Based on the synthesis of the experience and research results on the functional classification,highway design and highway safety plan,problems in highway classification in China are analyzed,the relationship between functional elassifieation and highway safety is discussed,and recommendation for the highway functional classifica- tion concerning highway safety in China is put forward.
