Functional Classifications
Alaska follows the Functional Classification (FC) system for the USA.
Lock Standards
In Alaska 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.
| Segment Type | Statewide |
|---|---|
| Freeway | 5 |
| Ramp | Highest Rank of Connected Segments |
| Major Highway | 3 |
| Minor Highway | 3 |
| Primary Street | 2 |
| Street | 1 |
| • • • • Ferry • • • • | 5 |
| |-|-|-|-|-|-|-|-|-| Railroad |-|-|-|-|-|-|-|-|-| | 2 |
Note: Certain roads may be locked higher than the above minimums. Please do not lower locks unless approved by the RC or SM of Alaska.
Note: Before locking these roads to these standards, you must verify that the name of the road, direction of the road, and turn functionality is correct. If this information is not correct, it should not be locked unless we are having issues with editors in the area. The only exception here is Freeways due to the routing priority. Refer to Unlock Requests if you need a section of road altered or unlocked to correct an issue.
Name Normalization
Alaska will use the following standards for road naming:
Freeways - I-###
US Highways - US-###
State Highways - AK-###
