【摘要】 山区公路小半径曲线是事故的多发地点。通过对行车轨迹及驾驶员行车视觉感觉的分析,结合曲线透视图,分析得出小半径曲线视觉信息不良是导致事故发生的主要原因。据此对小半径曲线加宽、横向超高及中心线设计中可能存在的安全问题进行了研究,提出了相对山区公路小半径曲线的道路安全设计建议。更多还原

【Abstract】 Small radius of mountainous highway is most likely to be the accident black spot.This paper is through the analysis of observed car path and driver’s sight information,integrating the road perspective,to conclude that bad vision information is the main cause leading to accident to small curve.Hereby this paper researches the likely issue in curve widen,horizontal slope and center traffic line,and presents correspond advice of road safe design.更多还原
