I'll leave it to the specialists to come up with those conditions. I really doubt we need it. People are unlikely to choose a minimum-noise route even if their satnav offered the option, not if it means the journey is longer or slower. People living nearby who are actually affected by road noise will know whether they have a loud road or a quiet one without our help. We won't be able to tell if the tag applies from satellite imagery. It will be hard to verify unless a community proudly puts up signs announcing they've spent money on such a surface. OTOH, people tag things like this just because they can, so we'll probably have to come up with something sane here before people make tags up at random. -- Paul
