Last SkiDooGuy Proposed Road Lock Standard

This chart uses information posted in the GLR Forum Thread: Great Lakes Road Lock Standards

In Michigan 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.

Alternate Proposed Road Lock Standard

The following defines a set of minimum locking standards proposed for all roads within Michigan. Any road of a certain type or category must be locked at least to the level in the chart below. Roads may be locked higher for protection and special situations (tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.

It is understood that more rural or inactive areas may not yet meet this standard: editors are encouraged to recruit and mentor additional editors to build coverage.

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.
