隧道群是高速公路事故多发的特殊路段,对云南某山区高速公路隧道群2014年的交通事故进行了事故分布特征及形态的统计,并分析了事故多发的原因。结果表明,碰撞是隧道群交通事故的主要形态;出入口是隧道群事故多发的主要区段;出入口明暗亮度快速交替转换和车辆运行速度过快是事故多发的主要致因。分析结果可为制定有效的隧道群路段行车安全保障方案提供技术支撑。
The tunnel group is a special section with frequent highway accidents. The accident distribution characteristics and morphological statistics of traffic accidents in a mountainous area of Yunnan highway tunnel group were analyzed, and the causes of frequent accidents were analyzed. The results show that collision is the main form of traffic accident in tunnel group. The entrances and exits are the main sections in which tunnel accidents occur frequently. The rapid alternation of brightness and darkness of entrance and exit and the too fast running speed of vehicles are the main causes of accidents. The results of the analysis can provide technical support for the formulation of an effective driving safety guarantee scheme for tunnel sections.
