Italy: R.A. Bettolle-Perugia -> RA6?

[michih]

Should it be RA6 as it is indicated on the brown "km posts"?

Km posts are a grey area. More yes than no? IIRC all Italian ones are big and in the median. Little different to reassurance shields.

I did investigate signage when I redid the system on migration from CHM, but perhaps I missed it, or had stricter rules (eg direction signage) back then.

Well, I mean the big brown km posts with white/green RA6 shield. Not the small black/white hectometer posts.
If memory serves, RA6 is not indicated anywhere on direction signs though. Just "Perugia".
And it has green motorway signs (autostrada), not blue motorway signs.

AGRA is also "green" (autostrada) and A90 is indicated on the brown km posts but AGRA is indicated on direction signs. It's fine too me but this route is in itaa system.
I think that RA6 should be autostrada (itaa system) too, not just eursf.

On the other hand, RA4 at Reggio Calabria (RARegCal eursf route in HB) has black/White km posts with additional white/green signs indicating "Racc. Aut." (RA) w/o number) or blue/white and white/green km posts with "Racc. Aut." also w/o number 
No brown km posts and no RA4 at all but RA. And blue instead of green motorway signs.

I drove RA11 from Ascoli to Martinsicuro today. There is no RA11 indicated anywhere and no brown km posts. GSV from August 2018 does not confirm what I have in my mind (Racc. Aut. w/o number as RA4) about the white on green km posts...
Then, I drove RA12 Chieti - Pescara. Also no RA12 numbering anywhere. White on green km posts indicate racc. aut. CH - PE.
Both routes have green motorway signs.

I'll drive another RA tomorrow (RA1@Bologna) but I think that everything should stay as-is except of RA6 which should be moved from eursf to itaa system. RA4 might be moved too.

I'll drive another RA tomorrow (RA1@Bologna)

The main route of RA1 has green motorway signs but no numbering nor km posts at all. One might think it's just carriageway no. 3+4 of A14. I didn't drive the Borgo Panigale segment.
