【摘要】 针对我国道路客运企业营运车辆交通事故发生频率较高的现状,结合因果图法,对客运企业内部可能导致交通事故发生的潜在风险源进行识别,建立了客运企业交通事故风险评价体系,结合企业调研数据,提出利用企业事故数据和评价指标组合数据进行聚类分析,定义了相似度的概念,通过对比两者聚类结果相似度,确定相似度最高的评价指标组合作为企业内部导致交通事故发生的重点风险源,并利用多元线性回归模型对最终结果的合理性进行了验证.更多还原

【Abstract】 Considering the high frequency of traffic crashes caused by inter-city transit vehicles,this paper intends to identify all potential risk sources inside enterprises,develop a corresponding risk evaluation index system with the method of cause-and-effect diagram,and perform an cluster analysis of crash data using the index system. The paper defines the concept of similarity degree and develops an evaluation index combination with highest similarity degree as the key sources of traffic crash risk for inter-city transit vehicles. A multivariate linear regression model is developed to verify the rationality of the final results.更多还原
