New technology on Oracle Road is helping traffic flow faster, government officials say.

The Arizona Department of Transportation installed traffic signals that adjust their timing based on how many vehicles are on the roadway.

Since the signals were introduced, travel times over the 8.5-mile distance between Tangerine Road and Rudasill Road south of Orange Grove Road have been cut by 10 percent.

More than 60,000 vehicles use the road each day.

"Sensors on the corridor provide information about the speed and volume of traffic on the road," said James Gomes, ADOT traffic engineer in Tucson, in a statement. "The software uses that data to send information to each traffic signal along the route and adjust the signal timing to accommodate the traffic demand we're experiencing at the time."
