Hi Sven,
Anyway looking at the patch this seems to be incomplete. We should synthesise a cycleway for the following tags: track,left,rigt,lane and yes.
Where left or right will imply oneway=yes.
I have no problem with matching more tags. However, left, right and yes are not discussed on http://wiki.openstreetmap.org/wiki/Key:cycleway how are they meant to be used?
I have also tweaked the code for making opposite cycleways - it now gives the synthesised way a highway=cycleway tag which it wasn't doing before.
Hm, I'm not shure if this is a good idea, because the Garmin devices tend to prefer real cycleways over generic roads. This may not be the expected behaviour for one-way roads thus it might be better to assign the real type of "highway".
Sorry, not sure what you're saying here. Cheers, Mark
