Hi all I'm the guilty party who split up the roundabouts in question to put the bus route relation through it. What do we want correct roundabout junction tags or correct bus routes? I did it this way by splitting the roundabout because it's obviously a roundabout from it shape and relationships to adjoining roads but the bus route doesn't physically use the whole roundabout and so I felt it incorrect to show the route using bits of road it doesn't physically pass over - especially on such large roundabouts Having said that it's a pain in the butt to keep splitting roundabouts for bus routes and I plead guilty (again!) to using whole roundabouts elsewhere on bus routes ( usually much smaller ones than the ones in question.)
Most public transport route maps do show the whole roundabout as part of the route - perhaps we should follow their example? The whole thing is inconsistent, including the mappers! Some guidance on a wiki somewhere needed perhaps, or a whole better way of adding route relations. Another issue - some roads can get quite chopped up to cope with route relations where several different bus routes turn off and turn onto the road/down adjoing roadsand then you can lose the sense of the continuity of the road Regards Brian
