对运输车辆安全行为的综合评价

Comprehensive Evaluation of Safety Behavior of Transportation Vehicles

通过建立模糊综合评价模型,运用AHP-熵值法结合主观和客观的方式确定组合权重。对运输车辆的安全,节能,效率三个方面考虑并结合气象和道路状况因素,合理确定各层次指标数,定性或者定量的分析各个因素对运输车辆行车安全行为的影响,通过建立逐步回归模型,得到日降水量和交通事故发生是显著正相关,和日均温度是显著负相关的关系,并拟合出函数关系方程。最后通过确定四类评价准则:优,良,一般,差,建立完整的评价指标体系和综合评价模型。

Through the establishment of a fuzzy comprehensive evaluation model,the combination weight is determined by using AHP entropy method combined with subjective and objective methods.Con-sidering the safety,energy saving and efficiency of transport vehicles and combining meteorological and road condition factors,the number of indicators at different levels is reasonably determined,and the influence of each factor on the safety behavior of transport vehicles is qualitatively or quantitatively analyzed.By establishing a stepwise regression model,it is found that the daily precipitation is significantly positively correlated with the occurrence of traffic accidents and negatively cor-related with the daily average temperature,relation,and fit the functional relationship equation.Finally,through the determination of four types of evaluation criteria:excellent,good,general,poor,we establish a complete evaluation index system and comprehensive evaluation model.
