In England, a blinking green light means a controlled crosswalk.
If a pedestrian pushes a button, the light will turn (after a
moment) yellow and then red, and a walk sign (picture of stick man
walking) comes on and a buzzer sounds (for blind pedestrians).
After a little, the light turns yellow after which no pedestrian
can begin crossing and cars may start moving as long as there's no
one in the walk.  It's fairly efficient but depends on their
politeness.

Another useful thing about their traffic lights is that the yellow
comes on when the light's red but about to turn green.  That gives
everyone a chance to move their foot from the brake to the clutch.
I wish we could adopt that system...
