Traffic Signals Maintenance & Timing
Traffic Signals Operations
UDOT strives for world-class traffic signals where 99 percent are connected state-wide to one shared central system managed out of UDOT’s Traffic Operations Center.
Not only does the connectivity improve traffic flow but also allows us to make immediate adjustments and provides us instant notifications of problems and performance measures. If you ever encounter a signal that you feel isn’t working properly, let us know by using our Click ‘n Fix app or website.
