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?

    I think what he means is, from the point of the driver driving from the 50 to the 60 area:

    You drive fifty, then you pass a sign pointed away from you (towards oncomming traffic) saying 50. 65m further, you pass a sign pointed at you saying 60.

    In that case I would say the speedlimit is just different for that 65m stretch of road, based on the direction of travel. The speedlimit changes at the 50 sign if driving from 60 to 50, and at the 60 sign if driving from 50 to 60.

      If I misunderstood, and this what OP meant, then I agree with your reasoning and solution.
