Smart Information-Rich Traffic Signals

I love these traffic lights I saw in Suzhou, China (near Shanghai). Rather than the simple three-bit information of red, yellow, green, you get the count-down time for green and red. So you know exactly how many seconds of “go” you have left, as well as how long that red light will last. Rather than causing people to game the system, it simply makes driving around much easer and less stressful. Really, why don’t we do that everywhere? I know that some European cities have count-down clocks on green lights, but I had never seen them on the red as well.
