Can reprogrammed traffic lights save gas?

[PapaDAB]

How many times a day do you approach a traffic light and have it jump straight to yellow then right to red and you are in a panic from being just to close to stop? I bet you end up running it, that is if you’re in the front of all the the cars with no one in front of you.

I have a simple idea. What if the green light was programmed to start blinking ten seconds before it turned yellow? This now tells drivers that the green light has gone stale and to ease off the gas pedal and coast to a stop.

Drivers won’t run as many red lights causing accidents and fuel economy increases.

So if you feel like this would work, how do we get the traffic engineers to program the traffic signals around the country?
