osmnx VS osmnx-examples

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.

For the actual printing I used ripstop by the roll custom print service. To render the image to be printed I used an open source too, https://github.com/gboeing/osmnx

IIRC, it can generate graphs that are both unprojected and projected and convert between them, so it might be worth looking into the source code of it if you think that sounds like what you're looking for on the OSMNX GitHub repo

Geoff Boeing, the original author, provided an iPython notebook so you can run this yourself, but this script a friend of mine wrote may make it a bit simpler to run, if you wanna give it a shot yourself.
