交又类型(7—401) 7—401.1总则绝大多数公路都发生平面交叉。因此,平面交叉区域便同时成为每条公路不可分割的一部份。为了最大限度地减少平面交叉的交通冲突,并提供适宜的横越和转弯运行,平面交叉的几何设计必须加以仔细考虑。平面交叉的特点,在不同程度上取决于下面四个主要因素。这四个主要因素是 Handover Type (7-401) 7-401.1 General The crossings occur on most roads. As a result, the intersection of flat areas becomes an integral part of every road at the same time. In order to minimize cross-traffic conflicts and provide suitable cross-and-turn operations, the geometrical design of the plane intersection must be carefully considered. The characteristics of plane intersection depend in varying degrees on the following four main factors. These four main factors are
