| Abstract: | 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. |

| Keywords: | driving speed speed limit curvature changing rate |
