Functional classification
Puerto Rico does not participate or use the Functional Classification system.
- All freeways are set to ground level. If two freeways cross each other, look at the actual intersection to discover the layers of the intersection
- Road names should follow the PR-### format and a general rule of thumb is:
- PR-1 through PR-99 & PR-165 are Major Highways (those with Pink Shields are Freeways)
- PR-100 through PR-206, PR-250 & PR-251 are Minor Highways
- PR-300 through PR-9914 are Primary Streets
- When adding cardinal directions to street maps use the Spanish letter surrounded by parentheses
- (N) = Norte = North
- (S) = Sur = South
- (E) = Este = East
- (O) = Oeste = West
- Example: PR-52 (S)
- Calle and Avenida should be spelled out for proper TTS pronunciation.
Minimum Locking Standard
In Puerto Rico 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 | 1 (Auto) |
| Street | 1 (Auto) |
| Private Road | 1 (Auto) |
| • • • • Ferry • • • • | 5 |
| |-|-|-|-|-|-|-|-|-| Railroad |-|-|-|-|-|-|-|-|-| | 2 |
Note: Do Not Mass Edit just to update locks to these standards, these can be adjusted as you find them while editing other aspects of the segments such as FC, speed limits, naming, etc.
Some segments still warrant higher locks and care should be taken when setting segment lock to these standards to look for and protect these special setups with higher locks. Some examples; segments which are part of BDP, U-turn prevention, or using micro-doglegs, or other complex intersection setups.
See Puerto Rico/Major roads for guidance in Puerto Rico that may not be universal to all other states and territories.
