It was pointed out[3] that 'incline' is a tag and intended to indicate a *direction* and amount of inclination of *the road in relation to the mapping direction*, not the direction of the *vehicle driving* on the road.
that's not my reading/usage : yes incline=* is about the direction of the way. but it also not about the amount of inclination of the road, it's about the maximum inclination of this segment : you can have a route that goes up and then down to return to exactly the same altitude. Depending on whether the maximum incline is up or down, it will be incline=up or down and not incline=0/no. Having never seen a road that requires chains to be put when there is no ice nor snow, I wonder if the use of "@ (ice; snow)" even makes sense, i find it useless. To solve your problem, I think it is better to cut the highway=* into sections that go only up or down not both. (despite I find this sign absurd: a ice is just as slippery downhill as it is uphill and I have never yet seen someone put their chains at the top). You can then simplify with snow_chains=required snow_chains:4wd:forward=no PS: it seems that osm is using 4WD, not AWD, see the badly named 4wd_only=* Regards, Marc _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
