Indiana DOT provided intersection center points, which were used to create the intersections in Network Screening - Intersections. Indiana intersections follow the same criteria:
Intersection Legs:
Intersection leg definition: If a leg is within 50 feet of the center of the intersection, it will be included in the intersection.
Intersection leg overlaps are mitigated; if a leg of one intersection overlaps with a leg of another, the overlapped legs are shortened to half the length of the overlap.
Intersection Leg Lengths:
Intersection Legs in Urban Areas: 250 feet
Intersection Legs in Rural Areas: 500 feet
