Le rose sur OSM ne semble viser que les autoroutes, alors qu'elle devrait aussi concerner les routes nationales par définition "primary for national roads". Apparemment, il a été pris d'usage d'annoter les routes nationales en orange.


I would refer to the osm classes of primary, secondary and so on instead of colors which refer to a particular map style. Anyway, the documentation about which class maps onto which roads in Switzerland is here:

https://wiki.openstreetmap.org/wiki/Switzerland/Map_Features

Now the primary in particular has problems for example in Zurich (I don't know the situation in Lausanne) where signage just vanishes inside the city. They really don't want you to drive through the city, but take the ring around it.
