Strange Routemapping bike

#1

Hallo,
I got a strange routing result. If i put one via in the middle of the route the route is as expected.
Can not find a reason

Mapping_3_Points
Mapping_2_points

The first Link shows the correct route (highway=service). The route of the second link tries to avoid the road and use highway=footway

Results:

Speed are on all edges are ok.

I cant see any reason why the routing engine choose the second route. Any idea what I’am missing.

Thanks Ralf

I think it might be the same bug as here: https://github.com/graphhopper/graphhopper/issues/1831

#3

ok, I see.

I have’nt seen that there are
EnumEncodedValue roadAccessEnc = flagEncoder.getEnumEncodedValue(RoadAccess.KEY, RoadAccess.class);
and
flagEncoder.getAccessEnc()
giving back kind of 2 types of RoadAccess

First gives back “destination” on the avoided road.

Might be an idea to overwrite the value “destination” by Bike*Encoder after it has set by one of the parent classes.

Ralf
