Roadway SubBlock Intersection

Roads and Highways manages intersections, however they are not singular points; RH creates a series of points - one for each intersecting road at that intersection. For DDOT, it is more useful to have a single intersection point representing the intersection. Through a custom DDOT script,the series of intersection points is reduced into a single representative point. For more information please visit DDOT's wiki page.道路与公路系统（Roads and Highways，RH）负责管理道路交叉口，但其并非以单一点位进行表征；RH会为该交叉口的每条相交道路分别生成一个点位，由此形成一系列点位集合。对于DDOT而言，采用单个代表性点位来表征整个交叉口会更具实用价值。通过自定义的DDOT脚本，可将该系列交叉口点位整合为单个代表性点位。如需获取更多相关信息，请访问DDOT的维基页面。
