The city I live in has been installing countdown "walk" signals at new intersections in recent years - even the ones that are always green for through traffic in the absense of a cross-traffic vehicle activating a sensor.

I've also seen a road in another city where signal timing was used as a means to control speed: signs were posted saying, "Green signals timed for 40 km/h". Brilliant!

Peakster: don't the lights on the ring road around the Peg have a set of flashers upstream that warn you of an impending change? I seem to recall them on certain sections of the Trans Canada where there are lights occasionally stopping a flow of traffic going 100+ km/h.
