OsmAnd has a German Road Atlas style: http://docs.osmand.net/docs/user/map/vector-maps#road-style

And the OSM map also has different stlyes, like this traffic style which highlights important roads: https://www.openstreetmap.org/#map=13/52.4205/10.7808&layers...

[widerporst]

The Transport Map on OSM highlights bus lines, not important roads.
