If the pedestrians are trying to cross the road, roundabouts can be worse (unless the context is a slow, traffic calmed residential street). The research seems to suggest they're safer overall for drivers (because they have to slow down).
Drivers are concentrating on merging, and then on accelerating away from the roundabout once they reach their exit. They don't see pedestrians or cyclists, and even with marked crosswalks on the edges of the roundabout, they sometimes don't stop. If they do stop unexpectedly if they see a pedestrian on the crossing, it's quite likely they can get rear ended as the car behind isn't anticipating them stopping. If the crosswalk is moved away from the roundabout it becomes very inconvenient for pedestrians, who then tend to short-cut rather than diverting to the crosswalk.
