基于可能速度与层次分析法路线设计安全性评价

Safety appraise of road alignment design based on possible velocity and hiberarchy analytical method

引入可能速度,分析了可能速度在路线设计中的合理性和可行性,并利用与可能速度有关的各项安全指标,结合层次分析的方法,对道路设计安全性进行评价,得出评价的最终结果,对于建立一个科学系统的道路线形安全评价体系具有重要的意义。

This text led into the possible velocity, and analyzed the rationality and possibilities of possible velocity in alignment design, used va- rious safe indexs that related to possible velocity, then we apply to hiberarchy analytical method to appraise road alignment safety, get the result of the evaluation, it＇ s very meaningful for set up a scientific and systemic road alignment safety appraise system.
