[Talk-transit] Roundabout, ways and relationship policies

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
