基于AHP的高速公路安全设施收益空间分析

摘要

采用层次分析法分析高速公路安全设施收益空间的影响因素，建立层次分析模型，构造判断矩阵，确定影响高速公路安全设施收益空间的各组成部分的权重，对判断矩阵进行一致性检验。得出安全设施各部分收益空间由大到小的顺序为：波形梁护栏、混凝土护栏、交通标志、交通标线、隔离栅。该研究可为项目建设管理提供针对性的指导。%In this article,the influence factors of profit space of superhighway safety facilities are analyzed with the analytical hierarchy process (AHP).Then,the analytical hierarchy model is established to construct the judge matrix,determine the weight of each component and make a consistency test for the judge matrix.The test shows that the big to small order of profit space is as follows:the w-beam guardrail,concrete barrier,traffic sign,traffic marking and isolated barrier.This research can provide the guidance for the project construction management.
