|Used on these elements|
|Status: de facto|
|Tools for this tag|
cycleway=track is used to mark a cycleway that is not mapped with a separate geometry (other keys from this tag family are also in use - cycleway:left=track / cycleway:right=track / cycleway:both=track).
|cycleway=separate on road line|
highway=cycleway on line representing cycleway
Cycleway is not mapped as a separate line.
Tagging above assumes that line representing road is leading in direction away from photographer. See left and right for more info.
Relation to bicycle=use_sidepath
bicycle=* describes the access restriction for cyclists on a road or way. bicycle=use_sidepath specifically is set on the road line to indicate that cyclists are forbidden (in some cases partially forbidden) from cycling on the road itself because there is a compulsory cycle path mapped as a separate geometry. This implies that there is a separately mapped cycle path nearby.
cycleway=separate on the other hand only indicates that there is cycle path nearby that has been mapped separately. It does not make any statement about whether that separately mapped cycle path is compulsory or not.
