raster2osmand VS osmnx

The first step is to make georeference of the picture, because scaned map is just picture for any mapping system. It means that mapping system has to know what part of the map is the picture. This step can be done with qgis, locus map, ozi explorer ... When you have georeferenced picture like ozi.map geotiff or geopdf then you have convert it for osmand format: zxy tiles or sqlite. You can do it with qgis, mobac (if I remember) and script in python https://github.com/mariush444/raster2osmand

You want osmnx

OSM road network data was analyzed using osmnx (https://github.com/gboeing/osmnx). Plotted using QGIS.

I think you’re hitting this issue right now: https://github.com/gboeing/osmnx/issues/832

RDS-TMC transmits traffic data over FM radio. https://en.wikipedia.org/wiki/Traffic_message_channel Some is encrypted, some not.

It might be possible to model traffic with OSMnx to assign weights to roads by expected traffic levels https://github.com/gboeing/osmnx

Depending on where you live you might be able to get traffic data and maybe traffic models from public authorities using Freedom of Information requests.

Osmnx might also be a way to download data for the whole country. It breaks the area up in smaller parts automatically and also downloads the parts from Overpass. https://github.com/gboeing/osmnx

You can make your own with a variety of tools, but I like the results from OSMnx offhand.

I have no idea if this works for such large regions, but https://geoffboeing.com/publications/osmnx-complex-street-networks/ is an awesome tool to visualize street (and maybe bike) networks.
