It does take up quite a bit more land than a regular intersection, though (but not nearly as much as a cloverleaf would).
Patrick,I agree that the roundabout is 'way out ahead of nothing',but I'm trying to envision an infrastructure which can maintain momentum ( all of it ).
Mixing arteries and veins is a delicate matter.
We have a century of mediocre road design to remedy.
All traffic engineering manuals clearly spell out the relationship between conservation of momentum and efficiency.The physics is simple.
I'd like to see the experiment played out as we see in electronics,and other fields of technology.
