When an editor locks a segment, it currently has two functions.
A locked segment will not be changed by GPS tracks both in terms of geometry and directionality.
A locked segment cannot be changed by an editor of a rank lower than that of the locking editor, or the rank of the editor who last edited the segment.
A junction is considered to be locked when all segments which connect to that junction are locked.
Area Managers can override any locked segments, even if a segment is locked by an editor of higher rank
