I did and I'm just not seeing the improvement over an SPUI for vehicle traffic, it just moves the problem a little further away while adding an expense of driver confusion for the first few they encounter. It might be better for interchanges with pedestrian and bicycle traffic however.AlanOfTheBerg wrote:Use the links previously in this thread to read more about them.

I think the "issue" that it tries to solve is asshats making a left from freeway exit that enter and block intersections when the traffic is backed up, thereby causing a secondary jam on the crossing street. But it really doesn't, now it just moves the asshat point a little bit further out on the crossing street to the crossings on either side.gettingthere wrote:And what is the logic with this so called 'double diamond' crossing? To cause a head-on collision when someone doesn't think for a second and ends up on the incorrect side of the road?
And what purpose does this serve? Something similar to a traffic circle but more efficient?

All the ramps were already there and the arterial road (Telegraph Road) was already split, so I just edited the connectivity to make the intersection work. However, I suspect I will have to go back and simplify the interchange at some point.
