Roadway Intersection Approach

Intersection Approach Segments are short segments of the route that approach an intersection, in other words, a short section of the road leading up to an 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.
