摘　　要：为探究大货车-行人/两轮车交通事故严重程度影响因素,文章以成都市双流区322起该类交通事故为样本,将伤者是否死亡作为因变量,选择14个潜在影响因素作为自变量,构建二元logistic回归模型进行分析。结果表明:“车辆类型”“是否交叉口”“行驶状态”对事故严重程度影响显著。结合相关研究及成都实际情况得出这三类因素影响显著的原因,并针对性地提出事故预防措施。To investigate the factors affecting the severity of truck-pedestrian/bicycle accidents,this paper takes 322 such accidents in Shuangliu District,Chengdu as the sample,with the injury severity of the victims as the dependent variable,and selects 14 potential influencing factors as independent variables to build a binary logistic regression model for analysis.The results show that"vehicle type","whether at an intersection",and"driving condition"have a significant impact on the severity of the accidents.The reasons why these three factors have significant influence are analyzed based on relevant studies and the actual situation in Chengdu,and preventive measures are proposed accordingly.
