Strange routing on foot=yes path

Open Source Routing Engine

I observe a very strange routing on a path with foot=yes set:

Visual routing result is this:

the respective GH log output is

2016-05-12 11:07:48,100 [qtp1508269304-32] INFO com.graphhopper.http.GHBaseServlet - weighting=shortest&vehicle=foot&locale=de&point=47.69479190025941%2C11.906087452798335&point=47.69252434322466%2C11.903426701456135 127.0.0.1 en_US Apache-HttpClient/4.1.1 (java 1.5) [47.69479190025941,11.906087452798335, 47.69252434322466,11.903426701456135], took:0.089038946, , shortest, foot, alternatives: 1, distance0: 39.63634041681248, time0: 1min, points0: 3, debugInfo: idLookup:0.049057733s; , algoInit:0.004194334s, dijkstrabiCH-routing:0.016285792s, extract time:3.722E-6;, algoInit:0.004194334s, dijkstrabiCH-routing:0.016285792s, extract time:3.722E-6, simplify (3->3)

and the GH 0.6 DB is built with
graph.flagEncoders=car,foot,mtb|blockFords=false
and
prepare.chWeightings=shortest

Any ideas?

It looks like the subnetwork post-processing removed this way (and probably some more) due to disconnecting issues.

Maybe there is a ford in between - can you please try:

graph.flagEncoders=car,foot|blockFords=false,mtb|blockFords=false

There is no ford in between (i.e. on the way I’m test routing on in the above example), but there are 2 fords in the vicinity… Built with blockFords=false on foot now (I had assumed this flag was for all vehicle so far…) and now the routing is fine.

Thanks!

This seems not to work anymore. The following error has been displayed:
Error in custom provider, java.lang.IllegalArgumentException: Since 0.7 EncodingManager does no longer accept upper case profiles: car|blockFords=false,foot|blockFords=false

So I changed it to lowercase:
graph.flag_encoders=car|blockfords=false,foot|blockfords=false

But it didn’t work either, so I’m wasn’t able to make route through ford or between two fords. How can I fix this?

Oh, finally I’ve figured out how to do this. The correct flag is block_fords now.

graph.flag_encoders=car|block_fords=false,foot|block_fords=false
