This is awesome, although part of the traffic problem is the horrible condition of the roads around Seattle, and a failure to enforce basic traffic laws - specifically - the left lane is for passing, and probably more importantly, do not stop in an intersection. Just because the light is yellow, doesn't mean we need to stack more cars into the middle of the road.
I walked to work (when I lived in Seattle recently) but the amount of traffic jams I saw caused by both regular people in their cars, and the mass transit bus drivers, driving right into an intersection as the light turned red is crazy. I don't know how you can plan traffic flow around it, because as green as the light might be, no one is moving with a bus sitting in the middle of the intersection.
Plenty of selfish/oblivious drivers, but don't overlook the selfish pedestrians causing intersection traffic backup too. There are plenty that are crossing right up until the light is red (even if they don't have a "walk" signal), making it impossible for more than one car to make the left turn. Everyone needs to work together.
