Dallas has been promising a citywide smart traffic-signal network since at least 2014 — by December 2021 nearly half the city's signals still predated 1980, and the 2018 deal meant to fix that never reported hitting full coverage.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

The City of Dallas operates a Traffic Management Center at City Hall that centrally controls a subset of the city's roughly 1,500 traffic signals along with dynamic message signs, rail-crossing warnings and CCTV cameras, per the region's official ITS architecture. The city has spent over a decade trying to close the gap between that ambition and its aging signal fleet: a 2013 council briefing found 80% of signals had exceeded their 25-year design life and recommended a $250 million, 25-year replacement program the council did not fund; a 2018 partnership with Ericsson aimed for full remote signal synchronization by 2020, but a 2017 council update found only 440 of 1,500 intersections had cellular-modem controllers installed and 70% of intersections had broken vehicle detectors; by December 2021, 48.8% of signals still predated 1980. The city has continued incremental modernization since, funding $25.8 million in high-injury-location signal upgrades over FY2024-2025, but has not reported reaching citywide central control.
📊 Impact
As of a 2017 council update, 440 of ~1,500 intersections (about 29%) had cellular-modem signal controllers installed and 70% of intersections had broken vehicle detectors; a December 2021 council briefing found 48.8% of the city's signals predated 1980; the city's own street-services staff described the central signal-timing computer as 'at risk of failure.'
🎓 Lesson
A city can sign a headline smart-traffic contract and still be running most of its intersections on 1980s hardware a decade later — connectivity announcements and physical signal replacement are two different, separately fundable problems, and only one of them got funded here.
