I'm currently involved in a project where it is necessary to obtain (raster or vector) datasets wide average road speeds of an individual country. I saw the World Traffic Service has fixed speeds available for many countries, but it is unclear on using them as larger scale machine learning datasets. Is it possible to get raster tiles, geojsons, shapefiles or something that can be analyzed with our own models at scale with one of the APIs here (either paid or unpaid)?
