I agree to use smoothness only for a speed penalty. I thought I reconized the last example that you mentioned, but it was another bad road that I cycled on in Romania (pasul Rarau, a few km to the west of your example, was paved and horrible, now marked as footpath) [😉] ________________________________ OK, here is v3 of the patch based on v1. Changes: - also treat surface=paving_stones:30 as paved - treat highway=via_ferrata as unpaved - don't interpret smoothness=bad as unpaved Add spead penalty for roads with very_bad or worser smoothness if they are not flagged as unpaved highway=* & mkgmap:unpaved!=1 & smoothness ~ '.*(bad|horrible|impassable)' { add mkgmap:road-speed = '-2' } I still don't like this version. It sets mkgmap:unpaved=1 for highways which are explicitely mapped as paved, e.g. http://www.openstreetmap.org/way/150436049 which matches highway=tertiary & surface=paved & smoothness=very_bad or http://www.openstreetmap.org/way/38245394 There are quite a lot of major highways with a combination of paved surface and ugly smoothness. I think the smoothness tag should only be used to add a road speed penalty. Gerd <http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev>
