While we are here, an experimental junction tagging method may be considered. The proposed method involves drawing two oneway=alternating ways to form a triangular junction area, with appropriate turn restrictions. This preserves junction topology while maintaining reasonable GPS accuracy for navigation / mapmatching purposes involving Hang Shun Street (west side).
