I know this is Edmonton news, and everything Edmonton sucks on this board ;-), but this is cool.

It can take a person weeks or months to figure out by trial and error the best sequence for one traffic light. Back in 2004, the computer suggested a fix for a kilometre-long queue of drivers who were frequently stuck on the Yellowhead waiting to go northbound on St. Albert Trail. When Cheung ran the data, the modelling software suggested staggering the timing of the lights that allowed cars to turn onto the bridge.
He sat in his car beside the intersection to watch the next morning.
"I was screaming, 'Yeah, it worked,' " he said, still laughing at the memory. "The entire queue disappeared. We just cleared everybody out of there. It was actually what the model predicted. It was a big deal for me."
