Run analysis

Custom classification

The default OSRM profile asssumes that each road segment has a highway tag with a typical OSM value (eg. primary, secondary). If your road network uses a different classification, make sure to add them to the speed profile.

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.
