Hello list, I'm trying to get better bicycle routing in my Garmin map; however, I don't know much about styles and the Garmin mapping, so I thought it might be wise to ask questions first (and shoot later): What I thought I'd do is make a sort of double routing for bicycles: when a road is on national biking paths (at least in the Netherlands, this means a tag "network=ncn") or regional bike paths (network=rcn), I might want an extra road with higher routing preference, only for bikes. This would mean a sort of double road; but I'm hoping it will only affect bicycle routing: highway=unclassified & network!=ncn & network!=rcn [0x06 road_class=1 road_speed=2 resolution 21] highway=unclassified [0x06 road_class=1 road_speed=2 resolution 21 continue] highway=unclassified & network=ncn {set access=no; set bicycle=yes } [0x06 road_class=3 road_speed=1 resolution 18 continue] highway=unclassified & network=rcn {set access=no; set bicycle=yes } [0x06 road_class=2 road_speed=1 resolution 19] (This should probably be done for other types of highway as well, but I did not think the chances of a bike path going through a highway=primary too high ;) Also, in the same way, get different bicycle paths: highway=cycleway & network=ncn {add access = no; add bicycle = yes; add foot = yes} [0x16 road_class=3 road_speed=1 resolution 18] highway=cycleway & network=rcn {add access = no; add bicycle = yes; add foot = yes} [0x16 road_class=2 road_speed=1 resolution 19] highway=cycleway {add access = no; add bicycle = yes; add foot = yes} [0x16 road_class=2 road_speed=1 resolution 23] Would this, theoretically, work? (And if not, why not?) Best regards, Valentijn
