<br>
yes, just guesses from developers on the road and no literature
used. Would love to see some more solid ground for this e.g. using
OSM planet GPX<br>
<br>
Keep in mind that these speeds are not max speeds but average
speeds. The maxspeed tag is handled differently in applyMaxSpeed.<br>
<br>
Kind Regards,<br>

I am writing my master thesis about the influence of the
infrastructure on bicycle speed. Beside doing on-road
experiments I would like to give an overview, how routing
algorithm calculate the speed of bicyclist.<br>
<br>
I have seen, that graphhopper uses a list of maxspeed parameter
in <span style="background-color:rgb(255,255,255)"><a

<blockquote>setSurfaceSpeed("gravel", 12);<br>
setHighwaySpeed("service", 14); <br>

How did you defined these values? Are they just guesses? How did
you guessed them? Or could you find them somewhere in
literature?<br>
