This weeks Local Transport Today has an interesting article about Dutch style roundabouts called a turbo roundabouts.
They provide 1-1.5 time more capacity than traditional 2 lane roundabouts but with 50-70% less serious crashes than respectively traffic signalled & give-way junctions.
Struck me as a possible model for Paxton Green.
You can see a 70second video of the concept here:

Do you think it would help solve the problems at this intersection?
