In Crazycaveman we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.
|Highest Rank of Connected Segments|
Note: Rural locks may be increased to Urban locks once an area can be considered "complete" (correct turn restrictions, road classified appropriately, and minimal URs)
