摘要
通过对山区高速公路行车速度进行分析,提出限速的必要性。对85%位车速与圆曲线的曲率变化率CCRs进行回归分析,建立85%位车速与CCRs的回归模型,并结合金丽温高速公路,对如何确定高速公路直线段和曲线段的限速值给出建议。
Through analysis to driving speed in mountainous area expressways, this paper summons the necessity of speed limiting. It conducts regression analysis to 85% driving speed and curvature variation rate CCRs of circular curve, and sets up the regression model for 85% driving speed and CCRs. Furthermore, combined with Jinhua - Lishui - Wenzhou Expressway, this paper gives suggestions on how to determine the expressway straight sector and curve sector speed limit.
