Is there one, particular, traffic light in your area that drives you nuts with it's unwavering predictability?

Asked by Coloma (47193points) November 4th, 2016

There is one traffic signal near me that is so predictable, it drives me insane!
Every-single-time it is Red and you slow to a near or complete stop it turns Green that very second! Just a few minutes ago I was coming home and as I approached it turned Yellow. I slowed down and prepared to stop and then, it turned Red for, literally, 5 seconds, then Green again!

Is there some rhyme or reason for wacky traffic lights that cycle around in just a few seconds all the time?

There’s one at the end of my neighborhood that is triggered by weight. It is a tiny, 35 mph road that faces a 6-lane section of US41.

If you’re travelling 41, and someone stops at that red light, it’ll trigger a SUPER fast yellow light and go red on you. If traffic is heavy, it can happen twice while you’re waiting.

There could be a magnetic sensing loop buried in the pavement about 150 ft from the intersection. Look for a repaired rectangular cut about 3 ft x 4 ft in the pavement.
Maybe that sensor should have been placed about 50 ft back.
