Thanks, Jakob - this is pretty much exactly what I ended up doing yesterday! Here's what I ended up with (to be clear, this is for the 'joined' net):
<location netOffset="-683204.41,-4928882.5" convBoundary="0.00,0.00,2164.41,1916.16" origBoundary="-346.83,0.00,1817.58,2148.55" projParameter="+proj=utm +zone=32 +ellps=WGS84 +datum=WGS84 +units=m +no_defs"/> Note that I only adjusted the netOffset and projParameter attributes; I kept the convBoundary and origBoundary values the same as they were previously. Please let me know if that is problematic, although I ran part of the simulation and it looked pretty good when overlaid on Google Maps. FWIW, while I didn't spend a ton of time trying to make it perfect, I'd say the netOffset value I selected appears to be accurate to within a few meters. The other thing I'd like to make you aware of is that this network's Via Andrea Costa edge to the west of rotonda Fulvio Bernardini (the big roundabout) does not match well at all with Google Maps or OpenStreetMaps. I don't know if I will attempt to improve it, but if I do I will pass along the updated edge values.
