Current behavior

The route won't use way : https://www.openstreetmap.org/way/189481307#map=19/45.81754/6.96363
due to the hazmat:no tag.

It can use https://www.openstreetmap.org/way/4525912#map=13/45.8735/6.8924 which has a hazmat value of E (which probably just gets ignored entirely...)

probably due to vehicle type being set to -128 here instead of 128 ?? (but maybe thats some byte value magic)

openrouteservice/ors-engine/src/main/java/org/heigit/ors/routing/graphhopper/extensions/storages/HeavyVehicleAttributesGraphStorage.java

Line 102 in 5ded0a3

orsEdges.setBytes(edgePointer + efVehicleType, byteValues, 2);

For the example requests, the edge for the way with id 189481307 this expression will be true and return false in the next lne

openrouteservice/ors-engine/src/main/java/org/heigit/ors/routing/graphhopper/extensions/edgefilters/HeavyVehicleEdgeFilter.java

Line 158 in 78ec9ad

if ((edgeRestricted || dstFlag) && buffer[1] != vehicleType)

And therefore assign infinity in

openrouteservice/ors-engine/src/main/java/org/heigit/ors/routing/graphhopper/extensions/weighting/HgvAccessWeighting.java

Line 19 in 27a2e1f

return Double.POSITIVE_INFINITY;

For reproducible example click export in the osm link for the way above.

Expected behavior

Properly use hazmat:no ways if hazmat is not set as a vehicle restriction.
