(this thread is so long now, that I don't remember if I have inserted "my"
problem with bicycle=no/dismount)
Here in Italy we have heaps of pedestrian-only crossings, which are part
of dedicated combined foot-cycle paths or even pure cycle paths. The legal
requirements is that cyclists dismount to use them (which no cyclist does,
but that's a different story).
Mapping with JOSM (as I do) you are offered the possibility to map
Pedestrian Crossings specifiying whether they can be used by cyclists
(riding the bike) using the "cross on bicycle" option). If you select
"cross by bicycle" JODM inserts "bicycle=yes", if you select no crossing by
bicycle, JOSM inserts "bicycle=no". I only recently have started to insert
This feature of JOSM indicates to me that there is most likely widespread
use of bicycle=no on crossings with the meaning of bicycle=dismount.
(according to taginfo the combination crossing and bicycle is used on 42000
nodes, bicycle=dismount is used on 1900 nodes, bicycle=no is used on 56000
A similar problem exists with cycle barriers (chicanes), where often
bicycle=no is used to indicate that you have to dismount to pass the
I don't know how routers handle these cases.
I fear that in the end we will be landed with the impossibility for routers
to distinguish between bicycle=no and bicycle=dismount at least on nodes of
type crossing and barrier.
