The purpose of this check is to flag pedestrian areas that are not properly snapped to its intersecting/overlapping edges. Pedestrian areas are defined as Ways with highway=PEDESTRIAN and area=YES tags. Overlapping roads are Edges with any highway=** except highway=path, highway=steps, highway=footway, and highway=pedestrian tag, which are too narrow to allow vehicle access. This check only applies to pedestrian areas where all points of intersection with roads are not snapped. To be considered overlapping, pedestrian areas and roads must be at the same elevation, meaning, both the area and edge should have the same LayerTag and same LevelTag, if any. If these conditions are true, this check will flag pedestrian areas overlapping with unsnapped roads along with the unsnapped roads.
- Line id:223986287 is not snapped to the road with which it overlaps.
- Line id:575511688 is not snapped to the road with which it overlaps.
The check ensures that the Atlas object being evaluated is an Area. The roads that intersects the area is then verified to be properly snapped to the area. If not, the area, intersecting edge and any connected edges within the area are marked as flagged.
