Large busy overhead signs are not as helpful as simple arrows at each opportunity to turn. Maybe arrows on the pavement, just in front of the turn.

Our first roundabout around here had 13 (thirteen!) signs just before you entered, including a map. Disaster. Folks just want to know, which is the left-turn lane etc.

Btw is that the right link? It looks like an ordinary roundabout with right-turn ramps.
