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.
- Elevation -5 is used for non-drivable roads to help ensure that the routing engine does not try to connect or route drivers from roads onto non-roads by mistake. It acts to prevent false system reporting that the roads should be connected.
- 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 (for proper TTS pronunciation in spanish)
- (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 | 4 |
| Major Highway | 4 |
| Minor Highway | 3 |
| Primary Street | 2 |
| Street | 1 |
| • • • • Ferry • • • • | 5 |
