Well - what is a strict pedestrian only way? highway=pedestrian -
often can be used with bikes too (going slower)<br>
highway=footway -- often still outside cities and used for mtbiking
though maybe not allowed.<br>
highway=path & bicycle=no ---> very often nice mtbike trails
in countries where mtbiking is mainly forbidden like
Baden-Wuerttemberg or Austria.<br>
<br>
<br>
And yeah - oneways could be excluded - but needs some care to not
exclude them (for cycling maps) if oneway:bicycle=no;
bicycle:oneway=no; oneway:bicycle=both; ( cycleway=* &
cycleway!=oneway ) would be the most common keys which mean cycling
against oneway direction is allowed.<br>
<br>
For me excluding all ways that get tagged road-class=0 or 1, and
road-speed=0 could be excluded (but sometimes I use continue and
double ways so it exists with say road-class=4, road-speed=2 as well
as road-class=0, road-speed=0 in order to get me through sharp turns
- if the sharp angle fixing would work well - maybe I could drop
this).<br>

<div dir="ltr">Hi Felix,<br>
<br>
okay, I just try to find some criteria so that we find those
nodes + arcs which really cause<br>
trouble. A lot of sharp angles are between oneway roads which
don't allow traveleling<br>
the sharp angle. <br>
I think that also means that I can add code to ignore sharp
angles on pedestrian-only<br>
ways.<br>

<div>Well - not in Pedestrian mode. I meant if you design a
map with road-class=4 as preferred way for pedestrians...
Then of course using a non pedestrian profile for routing
so it chooses road-class=4 or 3 preferably. <br>
</div>
For Pedestrian mode chosen - there is no time penalty for
sharp turns - though I did not test if it would prefer ways
that point towards the destination at intersections.<br>

please check:<br>
you said that sharp angles also have an effect on
pedestrian routing,<br>
I was not able to reproduce that. Can you give an
example?<span class="ecxHOEnZb"><font color="#888888"><br>
