I've been using OSRM a lot for bicycle routing in Toronto and haven't
seen many route suggestions that I would consider terribly unreasonable.
Sidewalks only ever appear at the start/end of a route because they may
be slightly closer to the requested destination.

For our researches, we use the OSRM routing engine, in which the
default profile for bicycle sets the footway to walking speed (5 km/h)
instead of bicycle speed (around 15-20 km/h), which is the same as
dismounting for routing purpose.

Which routing engines are causing problems exactly? Routing a bicycle
on a sidewalk may be appropriate/reasonable in some cases and over
short distances where one could be instructed to dismount and walk.
I'd be interested to see some of the problematic routes that are
being suggested to see if there isn't a more elegant way of resolving
this.
I personally only use explicit access tags where there is clear
signage indicating some type of special access restriction. Otherwise
the default should be assumed. Routing engines /should/ be able to
accommodate region differences in default values without needing to
manually tag millions of ways. Whether they can or do allow that is a
problem for the people developing the routing engines.

I'd recommend bicycle=no and I live in Ottawa. In Ottawa footpaths
that connect in general are bicycle=yes as they come under municipal
regulation but a sidewalk on a highway comes under provincial
legislation which bans bicycles on sidewalks. Sparks street is fun
I think you are not permitted to ride your bicycle but I'm unsure if
this is provincial, municipal or it might even be NCC which is
federal of course.
In the UK they are banned by law but in certain cities the Chief
Constable has stated the law will not be enforced within the police
force boundaries as a letter of interpretation. It might be nice
for Ottawa to do the same sometime but there again we have City of
Ottawa police, OPP, RCMP and of course the PPS.

I don't think it's more tagging for the renderer as much as it's
being more specific(more data) to specify a abstract view: without
knowledge of Canadian/Provincial/Municipal laws about biking on
sidewalks.
I think Montreal and Gatineau are more enforced as Ottawa it is
illegal to bike on the sidewalk, but people are still doing it, but
that's beside the point.

Hi!
I would like to start a discussion on how we should deal with
sidewalks tagged separately, like it is is done in downtown
Ottawa and like we are starting to do in the Montreal region.
The issue is that by default highway=footway with or without
footway=sidewalk should have an implicit bicycle=no by default
according to this page:
https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access_restrictions
However, some osm users told me I should tag them with
bicycle=no everywhere because routing engines use sidewalks for
bicycle routing which is illegal in most part of Canada.
What are your thoughts on this ? Should we adapt to routing
engines or should routing engines fix the issue themselves?
Thanks!
