| 摘 要： | 山区公路长大下坡加小半径曲线是事故多发点。本文以某山区公路事故黑点为研究对象，通过对行车速度及车辆行车轨迹的分析，得出小半径曲线视觉信息不良及离心力过大是导致事故的主要原因。在对车辆侧向稳定性理论分析基础上，对改造前后运行车辆运行安全性进行了分析评价，并提出了山区公路小半径曲线的道路安全设计方法，以供参考。

| Abstract: | Mountain highway with long down-slope alignment and small-radius curve is most likely to be the accident black spot.The mountain highway blackspot was selected as research object,through the analysis about driving speed and observed car path.The conclusion was made that bad vision information and centrifugal force were the main causes leading to accident for small-radius curve.Based on the vehicle's lateral stability analysis,the driving vehicle's safety was evaluated between before the reconstruction and a... |
