Granada, Spain, not only has timers on crosswalks, the ped figure is animated! When it's green, the ped figure walks, when there is only 5 seconds left he starts hurrying. Pretty cute.
I've seen timers for traffic lights in many European cities, almost every larger town in Romania had them. They would not only count down how much time was left for the red, but also for the green.
I loved that! Unfortunately, none around here
Too bad, because I'd think it's cheap to add a timer to each street light, while the improvement to traffic flow, safety, fuel usage and smog is almost priceless.
