道路环境对双责事故受伤严重程度影响分析

摘要

The both-at-fault crashes have received increased attention in China and research efforts have been spent to investigate the effects of both extrinsic factors and intrinsic factor on this type of crash, among which road environment is one of the most important extrinsic factors. The paper applies a bivariate ordered probit model is to find out the road environment-related factors that affect the injury severity of the both-at-fault crashes. Suggestions and countermeasures are then given to reduce the injury severity and improve traffic safety.%目前,国内外有关双责事故的研究方兴未艾,特别是对道路环境因素对于双责事故受伤严重程度影响的研究更加缺乏.虽然道路环境是事故的外在因素,但通常对事故的发生以及受伤严重程度有着不可忽略的影响作用.本文正是基于上述背景,采用二项有序probit展开道路环境因素对双责事故受伤严重程度的影响研究分析,旨在探寻事故中道路环境因素对双方驾驶员受伤严重程度的显著影响因素,并针对这些影响因素提出相应的建议或措施来降低双责事故后果的严重性,为改善交通安全状况提供一定的参考.
