I'm torn on this.

On one hand, I'd love to see intersections react to traffic in real-time to optimize traffic flow.

On the other hand, I have an "intelligent" intersection near my house and the cycle that the lights follow is something I can't figure out. There are four traffic directions, left and right turns from all traffic directions, and an LRT line parallel to one of the roads. I'm absolutely sure there's a pattern, but given the number of inputs I don't think I'll ever figure it out. Some of the inputs are invisible (e.g., incoming LRT cars hidden by a hill).

I wonder if there's been any study weighing the benefits of a predictable light cycle vs an intelligent cycle.
