Offset speed limit signs: am I mapping this correctly?
Offset speed limit signs: am I mapping this correctly?
I have recently got into mapping traffic signs and speed limits where I can, but I realised I don't know what to do when mapping differing speed limit signs that are offset from each other. It's a transition from a 50km/h zone to a 60km/h zone but the signs are offset by 65m, making a sort of "no-mans land" in-between. I plan to map it with the in-between zone tagged with separate maxspeed:forward and maxspeed:backward tags. I assume it should be done this way because as a driver on the ground I would follow the speed limit signs on my side of the road as I passed them, having no knowledge of the reverse sign.
I guess I'm wondering if this is a logical way to map this?

@sven @openstreetmap I think the tagging you're showing *should* be fine, but as I think the
:forwardandbackwardtags aren't as widely supported I'd put the lower speed as a genericmaxspeedfor that bit of road as well. That way simple software will default to the lower limit and more sophisticated software will use the correct one.That's a good point! Keeping compatibility is important.
