摘要: 鉴于山区公路交通事故黑点成因的多样性,在定义山区公路事故黑点和动态非定长划分事故黑点鉴别路段的基础上,建立基于当量事故数的鉴别指标法的山区公路事故黑点鉴别模型,根据计算结果将事故黑点进行黑度划分并作相应描述。然后,运用粗糙集理论对各种不利因素进行辨析,从而判断事故黑点形成的主次因素,并利用层次分析法的判断矩阵量化山区公路事故黑点主要成因的各指标权重,对权重较大的指标进行优先治理,实现改善效益最大化,从而有效提高山区公路的行车安全性。

Abstract: Considering the complex formation causes of accident black spots of mountainous highway, based on defining accident black spots and dividing identified road sections dynamically, the identification model on accident black spots of mountainous highway was built. The model was based on the number of equivalent accidents. According to calculation results, blackness of accident black spots was divided and defined accordingly. Then, the rough set theory was used to analyze various unfavorable factors so as to diagnose the primary and secondary formation causes of accident black spots. And the judgment matrix of AHP was adopted to quantify each index weight of main cause. Furthermore, in order to get best improvement, the greater indexes, weights should be treated in priority. Thus, driving safety of mountainous highway can be improved effectively.

Key words: traffic and transportation engineering, mountainous highway, accident black spots, dynamic division for road sections, the rough set theory, AHP
