San Francisco's SFpark pilot wired 7,000 meters with sensors in 2011 to test prices that rise and fall with demand. The sensors proved too costly to maintain and were retired, but the city kept adjusting rates using meter-payment data instead — a system still running citywide today, cutting the circling for spaces that clogs streets.
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 →📊 Impact
In the 2011-2013 pilot areas, average time spent searching for parking fell 43% and vehicle-miles/GHG emissions from circling fell 30% versus control neighbourhoods, per SFMTA's 2014 evaluation.
🎓 Lesson
Pricing beats prohibition: demand-responsive rates changed driver behaviour where signs never did — and the approach survived losing its sensors by switching to data the city already had.

The in-ground parking sensor, and what replaced it
Buried bay sensors were the emblem of the smart-city decade. Three of the cities that installed them have since taken them out, and the fourth never put any in — a rare case where the atlas can watch a technology lose.

|---|---|---|---|---|---|---|---|
| SFpark Demand-Responsive ParkingSan Francisco, 🇺🇸 | 2011 | Live | Succeeded | Official | Utility or public operator | not public | The pilot that made demand-responsive pricing famous retired its sensors as too costly to maintain, and now sets kerb prices from payment data. |
| SmartPark — CBD In-Ground Parking Sensor NetworkWellington, 🇳🇿 | 2016 | Completed | Scaled back | Official | City government | NZ$1.5m to install (2016) | The council pulled the whole in-ground network after eight years and went back to simpler pay-by-plate meters. |
| Fastprk In-Ground Parking SensorsBarcelona, 🇪🇸 | 2011 | Completed | Scaled back | Independent | Private company | not public | The sensor city's own parking sensors scaled back; what drivers see today is built from what drivers pay, not from the ground. |
| Riyadh Parking: Priced Curbs & Camera PatrolsRiyadh, 🇸🇦 | 2024 | Live | Ongoing | Official | City government, Private company | not public | A later scheme skipped the ground entirely: priced bays, an app, and camera cars instead of buried sensors or wardens on foot. |
