An Evaluation of Management Level of Traffic Safety in Road Passenger Transportation Enterprises Based on Combination Weighting Method

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.
