基于事故数据的乘用车品牌类型耐撞性和攻击性分析

为分析我国道路环境下乘用车品牌类型的安全性,本文基于2014-2017年的事故数据,利用logit模型,考虑14种非车辆因素,分析了7种品牌类型的耐撞性和攻击性,检验了耐撞性和攻击性的相关性。分析结果表明,超豪华品牌的耐撞性在乘用车中最强,自主品牌轿车的攻击性最弱。综合耐撞性和攻击性的结果,豪华品牌轿车拥有最高的总体安全性。

In order to analyze the safety performance of different brands of passenger cars under Chinese road condition, this paper, using logit model and simultaneously taking 14 non-vehicle factors into consideration, estimated the crash-worthiness and crash aggressivity of seven brands of passenger cars based on the crash data from 2014 to 2017. The correlation between crashworthiness and crash aggressivity was examined. The analysis results showed that the crash-worthiness of the ultra-luxury brands were the strongest among passenger cars and the self-owned brands were the least aggressive. When combining the results of crash-worthiness and crash aggressivity;luxury brands have the highest overall safety performance.
