摘要
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。
Tunnel group is a special accident-prone section of mountain highway,in this paper the distribution and morphology of a mountain highway tunnel group in Yunnan Province in 2014 are counted up and the causes of accident are analyzed.The results show that collision is the main form of tunnel group traffic accident;the entrance and exit are the main sections of tunnel group accidents;and light brightness alternates quickly when driving in and out the tunnel and vehicle runs too fast are major causes of accidents.The results could provide technical support for development of effective traffic safety plan for tunnel group.
