A couple of things I'm seeing here:
The ferry does not have a duration tag so you will get default speeds; you could add duration data to http://www.openstreetmap.org/way/81817423#map=17/46.69224/7.90466&layers=D The default profiles set speed for ferries but they do not (yet) modify weights for ferries; you can set realistic speeds and independently change routing weights now; see https://www.openstreetmap.org/user/happygo/diary/40564 Related: we optimize on weight and not on speed; even though the road could be faster it can have a high weight penalty on it; check weight responses in http://project-osrm.org/docs/v5.10.0/api/#result-objects Hope that helps, Daniel J H On Wed, Nov 1, 2017 at 12:35 PM, michael spreng <[email protected]> wrote: > Hi > > We have a problem on routing.osm.ch, that a ferry is used too often, > even though I set the speed of the ferry very low, such that it should > only be used if there is an exceptionally long detour without it.
