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?
Maybe it would be better to use the lower speed limit in the "no-man's land", since it would be unfortunate to be driving too fast while thinking one is folliwing speed limit. I assume it's kind of ambigous what the allowed speed limit is?
For mapping, I agree with your logic. I just think we should err on the side of causion when things are ambigous.
Fair point! Better safe than sorry. On the other hand, drivers 'round here will go 20 over no matter what I designate it as lol. Kidding... kinda.
