城市道路小交角斜交叉口设计研究

Study on Design of Minor Angle Deflection Intersection of Urban Road

通过对小交角斜交叉口的平面设计分析,提出了小交角斜交叉口渠化设计的合理方案;另外通过对小交角斜交叉口的纵坡组合分析,推算出右转车道的坡度与右转缘石半径、车道宽度、道路纵坡和两条相交道路的夹角关系,为小交角斜交叉口的合理设计提出了一些观点和建议。

According to the analysis on the plane design of minor angle deflection intersection, the article puts forward the reasonable scheme of channelization design of minor angle deflection intersection. Based on the analyses of gradient combination of minor angle deflection intersection, the article deduces the relation between the right turn lane slope grade and the radius of right turn curb, lane width, road slope, and the angle of two intersected roads, which provides some viewpoints and suggestions for the reasonable design for minor angle deflection intersection.
