I'm testing it also, and every parameters go to add-on (and GraphHopper API) correctly. Anyway I also get something not precise results for bike/foot. Suggest to test it on some short path where is clear what is car and what is bike. I'm sure you will see that parameter work and that just GraphHopper gives too low priority to bike paths.

If I select bike or foot then always I hear "car mode" and I get a route over auto streets even there are definitively bike or hike paths.

That is a GraphHopper problem... I think development isn´t really finished. On the other side, the navigation starts always with car navigation (voice) as far as I know. It doesn´t depend of used navigation source.

@menion
attached 2 points
try car mode (from south to north)
graphHopper ignores highway

edit
i think graphHopper use "SHORT car" instead of "FAST car"

If I try the three routes (car. bike, hike) on their web page http://graphhopper.com/maps I always get the correct different routes.

So for me the addon is not really ready.

Start 47.781962,12.131824
End  47.749914,12.135172

Online route planner http://graphhopper.com/maps/?point=47.781962%2C12.131824&point=47.749914%2C12.135172

The biggest part is a cycle track on the Inn dike.
You can simply change car/bike/hike and you see the different routes. The Locus addon shows always the car route.

same here. Hmm it won't be a problem with add-on itself, but more with routing files I generate. I'll try to generate them with different parameters and let you know.

Btw. tramp - "So for me the addon is not really ready." - that's why add-on is just here on forum :)

Version 0.1.1

Interesting, I've just added possibility to choose between car fast/short and bike fast/short and seems that this extra parameter (short, fast) helps also on cycle roads. Give it a try ;)

Hi, how comes graphHoper routing compared to MapQuest and Brouter as for computed route quality and relevnce? Which data provider GH uses?
Did somebody perform more exhaustive tests?
I like that routing data are much smaller than for Brouter for the same area.
I have featire reqquest for highways and paid roads exclusion if supported by GH
Thanks for new offline routing service  :)

At this moment I've compared GH 0.1.1 with BRouter for shortest way.
1:0 for BRouter

here are the results:

Thank you, but only the car route is correct.
The other ones are partially on small streets even a official bike and foot path are in the neighborhood within 50 m.
You can see the correct routes on the graphhopper website with my examples.

Now I have no time to test because the weather is perfect to make a MTB tour :-)
