[http://www.openstreetmap.org/?lat=56.04021&lon=-3.35912&zoom=16&layers=B000FTF Here] we have a road with a segregated cycleway running alongside it. The way is classified using the [http://wiki.openstreetmap.org/wiki/Key:cycleway cycleway:left=track notation]

Osmarender, Mapnik and the Cyclemap all fail to render the cycleway alongside the road.

Doing :left and :right in the renderers is pretty difficult or almost impossible, although work is being done to add support in mapnik.

Until then, it's impossible to proceed with this ticket.

Out of curiosity, why so difficult? If it is difficult/impossible, then the notation itself should be deprecated and mappers told to use separate ways instead.

In a sense, mappers are already being told to do just that, by the statements by some that cycleway=track is deprecated. But I digress, that's just politics. :)

The technical difficulty is that up to now, neither of the two most-used rendering engines (mapnik and osmarender) could draw a line parallel to a way. As I said, work is being done on the mapnik render software right now, to incorporate just such a functionality. It still needs to be fleshed out and tested, but it opens up interesting possibilities in the future.

This is possibly the same problem: [http://www.openstreetmap.org/?lat=55.92922&lon=-3.20455&zoom=17&layers=B000FTF here] is Canaan Lane, for the sections that are oneway there is a counterflow cycle lane, marked with cycleway=opposite_lane. This doesn't get rendered with Mapnik or Osmarender.

We are now 17 months later now. Mapnik2 is comming up. Is the situation on the renderer possibilities changed?

Replying to [comment:3 ChrisB]:

: it is deprecated and against the common rule: if the ways are separated, draw a distinct way.

Now that Carto CSS is used to draw the default Mapnik style has the situation changed?
Carto supports any number of lines with or without offset to be drawn along the way. AFAIK it should be doable now, shouldn't it?

I think this is too specific for a generic purpose map. Cyclists can use opencyclemap. I will therefore close this issue as wontfix.
