摘要
针对道路交通的安全问题,在道路线形速度一致性评价指标定量化的基础上,依据模糊数学原理,使指标的界限模糊化,采用隶属度最大化原则,构建道路线形安全模糊评价等级,将模糊安全评价运用于道路中,证明用模糊隶属度的安全等级指标进行评价能更充分的利用道路交通安全信息。
Aiming at road traffic safety,based on qualification of road alignment speed consistency evaluating index,according to fuzzy mathematical theory which makes boundaries of the indicators fuzzy,the road safety fuzzy evaluation model is constructed by adopting the principle of maximizing membership.The fuzzy security assessment is used in roads to prove that the fuzzy membership of security level evaluating indicator can be fully utilized in road traffic safety information.
