[Talk-us] US Trunk road tagging

[MoiraPrime]

Why do you keep bringing up "ground truth" on a discussion about road importance.

If anything doesn't reflect ground truth, it's a road going back and forth between secondary and trunk on a rural stretch of Oklahoma state highway merely because the state decided to divide a couple sections of it. This is absurd. A road should not change importance like this.

I feel like this generally wouldn't reflect ground truth.

Random short island sections of interstate existing solely because someone thinks an interchange meets motorway quality should not exist (which is a repeated topic in the OSM US Slack).
I'd say wholly grade separated, controlled access and dual carriageway
with no at-grade intersections including at the ends. Downgrade to
link or some other classification at the last controlled interchange.
> 3. Trunks should be important roads that fill in gaps in the Interstate system between two large cities. This can be 4 lane US highways, but it can also be 2 lane US highways, 4 lane state highways, you get the idea. The main idea is that the road is filling an important gap in the interstate system.
That's what we have highway=primary for.
