I thought you'd be interested in these projected numbers of cars getting through various intersection designs. Have you heard of the diverging diamond interchange, at 3:20 in the video? It crosses lanes of traffic before the intersection to decrease the number of points in the intersection where head-on collisions can occur. Apparently they're starting to build those near Seattle.
Some of the later designs after that in the video are quite elaborate and unusual. It's too bad they don't factor in the construction cost which would be a big impediment to improving congestion.
Tom.
