If the analysis fails with a

highway tag with a typical OSM value (eg.

A road network with the following classification:
<tag k="highway" v="departmental"/> <tag k="highway" v="national"/>
requires the following additions:
Any road segment that has no tags matching the ones in the OSRM profile, will be discarded when generating the routing graph.
