some pedestrian streets allow bicycling, using the bicycle=yes tag. osrm correctly allows routing on these, but seems to uses the pedestrian speed instead of the default cycling speed.

for example i might have this in my speedprofile:

defaultSpeed = 17
pedestrian=5

when routing on a way with highway=pedestrin & bicycle=yes, osrm should use the speed 17, not 5 (perhaps by choosing the highest of the two values?).

even better would be two have two settings for such 'slow' ways: one for pushing bikes (when cycling is not allowed), and one for cycling (when cycling is allowed).
