Hi,
I was a bit busy these days. Just drove around this new roundabout and recorded a better GPX (https://www.openstreetmap.org/user/damianeue/traces/11459676). As you can see (and as I edited), Luciani is actually linked to Monte Carmelo, I just need (and will in a few days) add a give way sign, a stop sign and a speed bump. Luciani part that is linked to Monte Carmelo has no lane markings at the moment but I hope they will paint them in a short time.
