Weired routing result near the phnompenh airport road

Hi. I’ve found some routing issue near the phnonpenh airport (In Cambodia).
First image is result of OpenStreet map and Graphhopper map (https://graphhopper.com/maps/)


This result looks good.

Second image is my local result.

Route should be linked to airport gate, but it doesn’t go through airport road.
I’ve tested using routing data (osm.pbf) files from OSM’s latest data and bbike mirror.
And I’ve tested opensource graphhopper engine version 0.12, 0.13 and 1.0-pre.
Config file used each version’s config-example file.
All version show same results like above.

I can’t find out the reason.

Likely there is a barrier node and we block it by default but this can be “relaxed”. Can you give a link to the OSM way?

Do you mean this link?

Yes.
There is this barrier: https://www.openstreetmap.org/node/6896555239 where the default is “inaccessible”. You should be able change this with

graphhopper:
   ...
   graph.flag_encoders=car|block_barriers=false

(remove the graph folder to force a re-import to apply this config change)
