An Evaluation of Management Level of Traffic Safety in Road Passenger Transportation Enterprises Based on Combination Weighting Method
-
摘要: 针对目前我国道路客运企业安全评价内容多为定性评价的现状,以道路客运企业的交通安全管理内容为研究对象,对16家客运企业展开实地调研工作,获取相关数据及材料。以此为基础,针对客运企业安全管理现状,建立了一套将企业安全管理内容划分为企业制度、驾驶员及车辆3个方面的企业安全管理水平评价指标体系。结合主观赋权法中的层次分析法和客观赋权法中的熵值法对指标进行组合赋权,并利用表征客运企业交通安全管理水平的事故数据分别对组合赋权法计算结果和层次分析法及熵值法计算结果进行相关性分析。结果表明,组合赋权法的相关性达到-0.841,优于层次分析法的-0.793和熵值法的-0.754。通过组合赋权法得到的企业评分排序结果也与事故数据排序结果基本一致,表明利用该组合赋权法可以对道路客运企业交通安全管理水平作出更为真实客观的评价。Abstract: Qualitative evaluations on the safety of road passengers have been widely accepted by most transportation enterprises in China.Current studies are thus motivated,and a survey of 16 road passenger transportation enterprises is conducted to obtain relevant data.An evaluation system of traffic safety is established,which includes three major indi-ces:enterprise system,drivers,and vehicles.A combination weighting method of analytic hierarchy process (APH)and an entropy method is applied for determining the weight of these indices.Statistical data of the management level of traffic safety in enterprises are therefore used for correlation analysis.The results show that the Pearson correlation coefficient of this combination weighting method reaches -0.841,better than -0.793 in AHP,and -0.754 in entropy method.More-over,the ranking order of enterprises is generally consistent with the safety statistical data,which indicates that this combination weighting method can objectively reflect the actual management level of traffic safety in road passenger trans-portation enterprises.
