摘　　要：随着我国交通运输事业的发展,城乡居民车辆保有率不断提高,在双车道公路交通场景超车时易发生事故,对双车道干线公路进行有针对性的交通安全设计有着重要意义。首先针对交通事故发生潜在特点进行统计分析,包括事故类型分析、时刻以及分布分析;在统计基础上对事故发生原因进行分析,包括驾驶员行为分析和道路条件分析;针对双车道公路超车安全性不足问题,提出了交通安全设计关键技术理论并进行深入分析,包括视距理论分析以及公路线形理论分析。研究成果可为双车道干线公路的交通安全设计提供理论指导,从而减少事故发生率。With the development of China's transportation industry,the vehicle ownership rates of urban and rural residents continue to improve.In the two-lane highway traffic scene,the most frequent accidents occur when overtaking,so it is of great significance to carry out the targeted traffic safety design for the two-lane trunk highway.Firstly,the potential characteristics of traffic accidents are analyzed,including the analysis of accident type,time and distribution;On the basis of statistics,the causes of accidents are analyzed,including analysis of drivers'behaviors and road conditions;aiming at the problem of insufficient overtaking safety of the two-lane highway,the theories of key technologies of the traffic safety design are put forward and deeply analyzed,including sight distance theory and highway line theory.The research results can provide theoretical guidance for the traffic safety design of the two-lane trunk highway,so as to reduce the accident rate.
