Advance’s detections will now activate non-flashing signs that warn of the upcoming intersection in order to make the intersection safer for all drivers.

PROVO, UT—The Ohio Department of Transportation is removing “Prepare to Stop” flashing warning signs from three intersections and replacing them with SmartSensor Advance units in an effort to help drivers pass through the intersections more safely. Tyrell Thompson, a transportation engineer with ODOT’s District 5, told the Lancaster Eagle Gazette that there is data showing the flashing signs at three locations are actually contributing to crashes and not preventing them.
“The theory is that drivers speed up to beat the red light when the warning flashers activate, which is why they are being removed,” Thompson is quoted as saying.
The problem, according to Thompson, is the driver dilemma zone, and area before the intersection where a driver must decide whether to stop or proceed when the light turns yellow. Ohio DOT has found that flashing warning signs actually increase the likelihood that drivers will try to beat the light, resulting in several severe accidents.
SmartSensor Advance uses a unique SafeArrival technology to protect drivers by extending the green light when a vehicle is detected in a dilemma zone. Advance bases the dilemma zone on each individual vehicle’s speed and distance from the intersection. Advance’s detections will now activate non-flashing signs that warn of the upcoming intersection in order to make the intersection safer for all drivers.
“We have the data that shows there are severe crashes attributed to that type of [flashing warning] signing that’s out there,” Thompson said. “We feel we can move forward with a safer type of warning device with the static signs and the type of zone detection we want to put out there.”
