Optaplanner VRP Edge_weight_section

Using optaplanner I have started solving VRP's however all my distances are extremely high, in the range of 33000 km, I have been using graphhopper API to determine edge weights for my locations.

When testing the Belgium data given in optaplanner however, the edge weights given by graphhopper differ completely from that used in the EDGE_WEIGHT_SECTION in the .vrp files

The Belgium datasets where generated by this code a few years ago. That code uses GraphHopper too. The road-km datasets should give you about the same distance numbers between any 2 locations as you generate yourself, if you use the same locations set. If that's not the case, give a clear example of how they differ.

Do note that updated openstreetmaps files will lead to slight km distance changes, as new roads (=shortcuts) become available.
