Thank you for replying, IMHO you should not perform this kind of "fix", because it only hides the real problems. I have now tried to fix most of the problems in the area (as in differences to reality and possible turns and driving directions for psv), but there is still an open case with Via Marmorata, where it might be disputable how many carriageways there are in the initial part (from the city gate down to the fire station). You deleted the central way between the rails without local knowledge, please be more careful (I actually agree it could have been deleted, paying attention to the connection network, but not without local knowledge).
