San Jose linked its traffic lights to one control room in 2007 -- the system grew to span four Central Valley provinces, but its electronics went two years without maintenance after the original contract lapsed.

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. All four grades →

San Jose's centralised traffic-signal system launched with 325 intersections in November 2007 under MOPT and contractor Semex, and has grown into a 474-signal network spanning San Jose, Alajuela, Heredia and Cartago, all watched from one Traffic Control Center and mostly converted to solar power by 2019 -- though a lapsed maintenance contract left its electronics unrepaired for two years afterward.

Live 📅 since 2007

📊 Impact

Authorities estimated the centralised signal system saves the country about US$3 million a year in time and fuel otherwise lost to congestion (MOPT estimate, 2011) — an estimate, not a measured evaluation.

🎓 Lesson

A complete, working signal network can still degrade quietly once its maintenance contract lapses: Costa Rica's traffic engineers went two years without electronics support before a new contract restored it.
