Existing traffic signals have been updated to newer equipment that includes controllers that send real-time data about the signal operations to the Traffic Operations Center.
With the upgraded controllers, UDOT can troubleshoot issues remotely such as noticing a stuck pedestrian button or verifying signal timing.
Traffic engineers can track data that used to require manual labor such as traffic speeds, traffic volumes and percent arrival on green.
Out of 249 signals operated by UDOT in Region Three, 211 have been upgraded to gather this real-time traffic data for analysis and optimization of the system. “Small adjustments can sometimes make a big difference for our traffic operations,” said
Adam Lough, Region Three Engineering Manager.
“The upgraded signal controllers allow us to make these adjustments and monitor how the intersection is operating without being on-site.”
