    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 &amp;&nbsp; bicycle=no ---&gt; 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=* &amp;
    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>

        <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
