1. A method for determining limited access highway entrance points for a geographic information system, the method comprising:
- generating a fishbone map that contains intersections points between a plurality of street segments with a plurality of limited access highways;
identifying limited access highway entrance points by analyzing a first set of attributes of the plurality of street segments that intersect the plurality of limited access highways within the fishbone map to determine the limited access highway entrance points; and
storing an identification corresponding to the limited access highway access points in the geographic information system.
