基于灰色聚类评估法的城市交通安全评价研究

Metropolitan Roads Safety Evaluation Based on Gray Clustering Mathematic Method

根据影响城市道路交通安全的各个因素,建立一套安全评价指标体系。运用灰色聚类方法进行安全评价,建立评价模型,并运用该模型对石家庄市城市道路交通进行安全评价,得到更符合实际安全现状的评价结果。

A safety evaluating system is established in accordance with various factors influencing safety of the metropolitan roads.This paper applies gray clustering method to evaluate road safety,establishes an evaluation model and through it evaluates the safety of roads in Shijiazhuang.It is found that the proposed model produces more realistic safety indices than others.
