Johannesburg's Traffic Signals: Remote Fault Monitoring and the Backup Batteries That Were Stolen

Johannesburg's roads agency says its remote monitors catch over 90% of signal faults before drivers do. Of 1,400 backup batteries meant to keep lights on, fewer than 15 still worked in 2025.
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. All four grades →Part of 1001 Smart Cities — 1,216 documented projects · 🏙️ 11 more in Johannesburg · 🚦 Traffic management guide · 🚲 Mobility projects
The Johannesburg Roads Agency, wholly owned by the City, runs the city's traffic signals: 2,023 signalised intersections in January 2025; the province manages 275 more. In May 2014 it launched the Find&Fix app for GPS-tagged photo reports of dead signals, and by 2016 was fitting Remote Monitoring Systems to its signal controllers; by January 2025 it said these covered over 80% of controllers and caught over 90% of faults before the public noticed. The agency put power-related outages at about 31% of lights at any time, 51% during load shedding, and of 1,400 backup batteries installed fewer than 15 still worked after theft.
📊 Impact
The only outcome figures are the agency's own. For 2024/25 the City's integrated annual report records that 79.49% of reported faulty traffic signals were repaired within 24 hours, 88.67% within 48 hours and 96.29% within seven days, against service standards of 40%, 60% and 80%. Uptime tells the other half: the JRA told Daily Maverick in January 2025 that 80% of the signals it manages were working at any given time in the quarter to December 2024. For the app, the agency claimed in 2015 that the average time to resolve requests logged through Find&Fix had fallen to six days. No independent measurement of any of these figures has been located.
🎓 Lesson
A fault-detection layer shortens the time between a signal going dark and a crew knowing about it; it does nothing about the two causes that keep Johannesburg's signals dark, grid power and theft. The agency's own sequence shows the limit: 200 backup batteries installed in 2006, 1,400 units later and fewer than 15 working by 2025, a repair backlog above R70 million, and by 2025 a search for private firms to wire signals to their own backup power and for controller boxes with electronic locks and alarms. Remote monitoring made the outage visible; it could not make the intersection resilient.

Report from a JRA media tour. States that the agency managed 2,025 traffic signal intersections, 750 of them semi vehicle-actuated and 25 fully actuated; that it is deploying secured controller boxes opened only by an electronic access system, with cameras and sensors whose alarms go to the city's Integrated Intelligence Operations Centre; that rebuilding a vandalised intersection costs R500,000 to R1.5 million; and that 84% of traffic signal faults were repaired within 24 to 48 hours.
