The pedestrians, already have a 20-30 second count down, on pedestrian lights.
How much more do you need to spoon feed it to them?
They assume people are stupid, maybe they are right?
maybe we just need a count down timer on the green light.
It does not matter if there is a count down timer on the green, or a 20 second timer on on the yellow.
The same drivers, are still going through with .01 seconds remaining.
Slow down. Think a little.
