Complex Road Attribution Layer
Complex Road consists of opposing groups of segments along a multi-carriageway between two Intersections. Complex Roads are created from multiple-digitized coded segments
Complex Objects are larger intersections comprised of a group of segments and junctions. These connect to form a grade separated crossing such as a motorway exit, motorway interchange, or exit from a multi-carriageway.
Complex Intersections consists of segments, nodes, and junctions that intersect at grade.
