Hi, today I got this warning: 2013/03/15 13:13:11 WARNING (RestrictionRelation): 63240002.osm.pbf: Turn restriction http://www.openstreetmap.org/browse/relation/2818347 (at http://www.openstreetmap.org/?mlat=60.17315&mlon=24.92289&zoom=17) lacks 'restriction' tag (e.g. no_left_turn) The wiki http://wiki.openstreetmap.org/wiki/Relation:restriction says that restriction:bus=no_right_turn is valid markup. It also lists things like restriction:motorcar and restriction:bicycle. Currently, mkgmap only supports the 'except' tag for restrictions. So, I guess that the above might be written as restriction=no_right_turn except=motorcar;bicycle I think that it is cleaner to use restriction:* for explicitly defining the restricted vehicle classes, unless it is restricted for all. (Sometimes buses can go straight while others must turn, on a lane that is primarily reserved for public transport. This one is a sharp turn to a narrow road, probably too sharp for wider vehicles. Or they want to restrict tourist bus traffic in the area.) Best regards, Marko
