The Indiana Department of Transportation is testing signs along State Road 37 in Morgan County that tell drivers how fast to go if drivers want to make the next green light.
As of now the signals are only located leading up to the S.R. 144 intersection near Waverly.
INDOT spokesperson Harry Maginity with says the concept is based around safety and convenience, but that’s only if drivers are willing to utilize it.
The signs are in constant communication with the upcoming traffic signal, and they determine what speed drivers should drive to avoid having to stop at the light.
Maginity says it makes traffic more efficient by cutting down the number of drivers waiting for a light.
“If you can go right through it, you’re actually saving time,” he says. “You’re sure saving some frustration and you’re saving the loss of sitting there at the red light, idling and letting gas burn and letting emissions go up.”
He likens it to a roundabout, where instead of waiting at a stop sign, traffic is constantly moving through that intersection.
INDOT says the move could also increase fuel efficiency and help lower carbon emissions.
