How can I map speed limits?

5mon 28d ago by lemmy.ml/u/MXC48 in openstreetmap@lemmy.ml

Recently, roadworks have been carried out on my road, completely changing the speed limits (new signs added, etc.). How can I add these to OpenStreetMap ID? I can't find the information online.

@MXC48

Key: maxspeed
Value: <number>

f.e.: maxspeed:50

If you want a simple way to map them, you can also use https://mapcomplete.org/maxspeed.html

To add to the other replies, you add it to the road. You can also add the speed signs if you want however

Ah, thank you! That's exactly what I was wondering!

@MXC48 The documentation for the speed limit tag is here:
https://wiki.openstreetmap.org/wiki/Key:maxspeed

The "default" iD editor has a field for this if you apply a road preset to a way.

@openstreetmap

Are these new speed limits only due to the roadworks or are they permanent? If it's the former, I probably wouldn't bother mapping it, or only if the construction lasts for at least a few months.

These new speed limit are permanent, so I want to add them
