Phoenix officials can’t verify progress on signal upgrades at 1,300 intersections
Phoenix officials have not been tracking a citywide upgrade to traffic-signal technology, leaving them unable to confirm whether newly installed equipment is working. A city transportation official said the city may soon begin monitoring the project’s progress.
Phoenix officials responsible for upgrading traffic-signal technology at 1,300 intersections have not been tracking the work’s progress, leaving the city unable to confirm whether the equipment being installed is functioning, according to information reported Oct. 23, 2026.
The project is intended to upgrade Phoenix’s glitch-prone traffic-signal technology across the city. Matt Wilson, assistant street transportation director, said Phoenix may soon begin tracking how the upgrade is going.
The lack of progress tracking means officials do not currently have a way to verify the performance of the new equipment as installation proceeds. No timeline or further details about the proposed monitoring were provided.
