I don't know when Portugal started this, but in Germany there is at least the concept of a "grüne Well" (literally a green wave). Simply put: if you drive at the speed limit you won't get any red lights. Sadly the german administration barely makes use of this as it doesn't make them any money...

Many cities in the US do this along major roads. They'll time the lights to maximize traffic flow which ussally means if your driving the speed limit you'll at least get through 3-4 lights before you have to stop.
