The way to improve the safety of roundabouts is to use compact geometry to slow down the traffic.
Doesn't that depend upon how segregated? If junctions are reduced by using overpasses & subways, or if cyclists have separate signals, conflicts may be reduced, rather then increased.
Reducing traffic speeds, and using cycle-friendly roundabout design is best when traffic speeds are under 40 mph and traffic volume is low or moderate. If they are greater, there shoudl be a quiet route, either segregated infrastructure or a quiet route with limited motor traffic permeability.
I don't know about you, but I'd far rather have Mini V riding her bike to school on quiet streets and good segregated infrastructure than using a roundabout with compact geometry on a busy road.
