Electronic parking fences for Chengdu's shared bikes

Chengdu rolled out an 'electronic fence' (电子围栏) system for dockless shared bikes in 2018: riders who park outside designated zones get an app alert and, if not moved, a small dispatch fee, enforced through the bike operators' own GPS/geofencing plus city oversight. In Longquanyi District from March 2022, the city piloted a higher-precision version using Beidou satellite positioning — accurate to roughly a centimetre versus the older metre-level GPS — across about 2,800 fence points on 21,000+ smart-lock bikes, monitored via a district law-enforcement command centre using Bluetooth beacons at 78 key sites. Riders parking outside a zone face a ¥5 dispatch fee; the pilot also surfaced real friction — GPS drift and rider confusion about zone boundaries led the district to waive fees during a two-week grace period.

📊 Impact

Longquanyi District pilot (from March 2022): ~2,800 electronic-fence points, 21,000+ smart-lock bikes, 78 Bluetooth-monitored key zones, ¥5 dispatch fee for out-of-zone parking; Beidou positioning cited at roughly centimetre-level accuracy versus metre-level GPS (media-reported, district pilot scale).

🎓 Lesson

Precision positioning doesn't fix a geofencing system on its own — Chengdu's own pilot needed a fee amnesty because riders still couldn't reliably tell where the zone ended.
