In Viareggio [1], where I live, there is a similar road, that is "Variante Aurelia". It bypasses the centre and connects SS1 Aurelia from South to North, even if in Viareggio we have a "Via Aurelia" that cuts in the middle of the city. Variante Aurelia has no at-grade intersections, two lanes per direction and separate tracks, as in your case. It would be preferrable for routing programs as well. The only difference, I think, is that in your case it is a "comunal road", wheras in my case the signs on the Variante are SS1 on blue background, and these signs also indicate kilometers from Rome, just if it was the SS1 Aurelia indeed. Be sure to see how the signs are placed along that road, but by the way, even if they don't indicate explicitly SS12 (and road signs have a white - comunal - background), I would map the road as primary, given its importance and physical characteristics.
