Can we use any road network with geometry instead of OSM?

As the title says, can I use any road network as the Map Data? Does the map matching code strictly depend on the OSM data?

Thank you!

I'd like to ask the same question here, can we support road networks like GEOJSON instead of OSM?

Thank you!

For the benefit of anyone else reading this, the easiest way to include non OSM data is to convert it into osm.xml with a tool like https://github.com/Rub21/geojson2osm and then change the import script to read-xml rather than read-pbf here.
Two points is that conversion tool is incomplete or outdated so the xml needs to have a field for version with an integer (it can just be 1) and the changelog field should be an integer rather than a boolean. The second point is there needs to be a highway field (you can just rename a class field for instance in the geojson) with levels that correspond to the weights in roadtypes.json
