<div dir="ltr">Hi all,<br><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 href="https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/routing/util/BikeCommonFlagEncoder.java">B<span tabindex="-1" id=":10t.8" style="background-image:none;background-repeat:repeat" class="">ikeCommonFlagEncoder</span>.java</a>, like</span><br><blockquote>setSurfaceSpeed("gravel", 12);<br>setHighwaySpeed("service", 14); <br></blockquote>How did you defined these values? Are they just guesses? How did you guessed them? Or could you find them somewhere in literature?<br><div><br></div><div>Thank you for your information!<br></div><div>Regards, Dominic<br></div></div>
