These Traffic Lights Predict Your Behavior To Give You A Speedier Commute – [fastcoexist.com]
There should be a German word for that feeling when you desperately need to be somewhere on time, and the traffic lights seem like they’re conspiring against you. When the greens feel especially short, the reds especially long, and both appear as if they’re in cahoots to keep you idling.
It’s not a conspiracy, but it is something called fixed time control. Most intersections, if they don’t have embedded sensors under the road, abide by traffic light timing determined by observed data from years or months past. Fixed time control based on historical data is usually pretty accurate for specific intersections, but what if entire cities coordinated their traffic lights to cut down on mass commute times and fuel use?
