Even one way roads can have multiple lanes. Like dual carriage ways :) > Some good practices > on how to accurately estimate road width could also came > handy. I feel you could get road widths accurately enough based simply on the number of lanes and the type of highway. For example, a residential road with 2 lanes, one in each direction is usually about 6-7m wide. Motorways are usually the numbers of lanes times 3m + 3m each side of the road way to allow for break downs, or maybe you could even have lanes=* breakdown_lanes=* to make this more accurate, but in any case a 3 lane motorway will be about 15m wide (3 * 3 + 3 + 3). _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
