[OSRM-talk] Turning with bicycle / for pedestrians

Dear OSRM Community, Hi Dennis,
We are on the way to integrate OSRM for a hiking & cycling application in
Switzerland, by defining adapted profiles for these use cases.
We observe a unexpected behaviour - at least unexpected for bicycle and
hiking routes. I'm using iBikeCPH to illustrate the example, but the same
problem can be seen on http://project-osrm.org/ as well.
In difference to cars, bicycles in most cases and pedestrians for sure can
turn immediatly on a road without turn restrictions.
Given I want to cycle from one S-Station to another in Copenhagen, with a
stopover at a friend's place at Bellmansgade:
Since I'm cycling / walking, it does not make any sense to go to the very
end and back again in the small street - in reality I would turn
The deviation also adds additional time (2mins) and distance to my route.
The viapoint seems to be slighlty on the dead end way. Is there any option
/ possibility to avoid OSRM chosing a deviation, if the via point is just
slightly (say some few meters) into to the street?
I guess it would be depending on the profile - maybe there is a config in
the LUA that could be used while calculating the network?
All I saw after quite some searching was using turn restriction tags in
OSRM (cf.  and ). As far as I read, my problem is different and
rather basic: allowing turns at any time for biking / hiking profiles (and,
maybe in a second step, restrict them according to OSM tags, for bicycles).
Any opinions / suggestions / info about ongoing devs for that?
