UK doesn't use a rule like that, they're even much more strict than us using road numbers... > How much traffic passes over it, doesn't really matter.

I haven't really checked the situation in Vilvoorde, but one of the "rules" is that within a city center, primary becomes secondary if there's a ringway that will connect to the other primary roads to the city. For example: http://osm.org/go/0Eg4Fgm N8 is secondary in Zwevegem, since the N391 was made to create a ringway around Zwevegem. http://osm.org/go/0EpYdO2L N1 crosses centre of Antwerp, but becomes secondary within the Singel. I guess someone did something similar in Vilvoorde with the R22. Whether that should be done, not really sure here. I also wanted to point at Tienen, but I see it has been recently changed by someone: http://osm.org/go/0EqQDB8 There's the N29 coming in from the north, and the N3/N29 should stay primary because there's no ringway on the north. Now someone changed it to secondary which is incorrect IMO.
