Just imagine the CARnage if we (very much myself included) had to know which junction we needed to leave the roundabout, before arriving at it.
The main difference between an ordinary roundabout and a turbo-roundabout is that drivers have to choose their direction before they enter the roundabout circle. Each direction has a separate route on the circle. Weaving from one lane to the other is impossible due to ridges between the lanes. It is also not possible to drive around in circles on a turbo-roundabout. At one point your lane will automatically force you to leave the roundabout. With the potential weaving conflicts out of the way the vehicle throughput increases, but that and the multiple lanes make it undesirable to have level crossings with cycling or walking.
Here's the full blog from where that came but it does only serve as proof that I am the boringest man alive, if you're having trouble sleeping tonight, this might come in handy:-
