+0.9, actually landuse=highway is often interpreted as the right of way (the area that the street legally occupies, not all of it will necessarily be asphalt or even "street", it might include a ditch or strip of grass, areas to keep clear of other stuff, etc.). The currently suggested key (as far as I know) is area:highway http://taginfo.openstreetmap.org/search?q=area%3Ahighway To get the semantics right of trams in the street I guess you would for many cases need to use a lanes model which can then tell you in which lane the tram rails are (or between which lanes). Still in crossings stuff gets more complicated as tram lines tend to cross lanes because of different curve radiuses. cheers, Martin
