 I would love to hear more from programmers of routing engines. My intuition
 says that this level of complication is very low, but I could be wrong.

 I'm also not sure that turns *are* ofter restricted or prohibited. You're
 saying that in a left-drive country, cyclists in a cycling lane/track can't
 turn right in situations where motorists can? What do they have to do,
 continue to the next intersection, then double back? I find this implausible
 - why invest the money in a cycling track, then hobble cyclists like that?

In many places, it's illegal to turn across a restricted lane, be
it bike or otherwise.  In these cases, if you want to turn across the
lane, you go around the block in the opposite direction similar to a
cloverleaf.  From cycletracks where there's a median between it and the
adjacent road, the cycletrack either has it's own exits controlled by
traffic signal across the adjacent road or expects you to go around the
block, depending on whether or not there is space to provide
exit/enterance ramps.

 I'm against this.  If it's seperated by a curb, that counts as a median,
 and should be treated as a seperate way.


 IMHO, options are good. If it's separated by a median, that means you're
 justified in mapping it as a whole separate way. But a simple tag to
 indicate that – without all the effort – is a good thing.

Never mind simply tagging it loses spatial detail in the process, and
complicates routing engines (since turns are often restricted or
prohibited from the cycle track across the adjacent road and vice

 There's something here. If you look at:

 This is Springvale Rd, in Melbourne's eastern suburbs. I'm told that that

 cyclists. It's not really a bike lane, but there is some benefit for
 cyclists there.

I was a bit unclear.

copenhagen-style bike lane = single way by default.
I was suggesting that cycleway=track, tagged on a road, would mean a
*two-way* copenhagen-style bike lane, because cycleway=* is two-way by
default, track= means segregated from other traffic, and that's what the
logical combination of those two ideas would mean.

 Yeah, but it's really just an enhanced bike lane - a path for bikes that
 closely follows the road. To me, the follows the road is the crucial
 distinction, so it's a kind of cycleway=lane, possibly with another tag.

I disagree; cycleway=track and cycleway=lane both follow the road - if
they did not, I really think the cycleway should be drawn in
separately. To me, the crucial distinction is whether there is any
kind of 'barrier' between cycleway and the rest of the road. If there
is no barrier (but only stripes, colour difference or such), I use
cycleway=lane. If there is some (like a bump or a height difference,
such as here), I use cycleway=track. If the barrier has considerable
width (more than half a meter or so), I prefer to draw the cycleway
separately.

 In Denmark, especially in urban areas, cycleways are almost always
 constructed using curbstones.


These are known, in Australia at least, as Copenhagen-style bike lanes.
(Seems to have limited use outside Australia, from a quick google.)

Before:

After:
http://www.nearmap.com/?ll=-37.859191,144.978019z=21t=k


  cycleway=curb_delimited

That has the problem that some parts of the world spell it kerb.


 which is more accurate. A different approach altogether would be to
 use something like:

   cycleway=yes delimited:cycleway=curb


I think it should definitely be a kind of cycleway, rather than an extra
option:
cycleway=protected
cycleway=copenhagen
cycleway=segregated_lane
...

You would definitely want to tag it two-way or one-way though. I think
one-way is more common, but the example I pasted has both directions on the
one side of the street.
