- One Way
- Do Not Enter
It normally wouldn’t be necessary to tag anything extra beyond
oneway=yes; no router would violate that tag, at least for car routing. But in case you’re interested in mapping the signs themselves in detail, take a look at the MUTCD tagging guide:
The codes in the “Designation” column are what you’d put in
traffic_sign=US:(code) on a freestanding node.
Thank you for that information. I was unaware of that tagging method.
I’ll leave them out for now.
Here in Germany the (equivalent of) “Do not enter” can also occur on roads which aren’t one-way-streets. In those cases you need to work with turn-restrictions.
