Wuhan wired 15,000 sensors into 700 bridges and 100 tunnels for a citywide risk platform switched on in December 2024 — built to predict disasters, but still too new for an independent track record.

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.

Wuhan's city government switched on a unified safety-risk platform on 25 December 2024, aiming to replace after-the-fact emergency response with pre-event prediction across four hazard categories: urban 'lifeline' infrastructure, public safety, workplace safety and natural disasters. It pools weather, drainage and river-level data, watches 200 mapped waterlogging hotspots, and — its largest single sensor deployment — reads 15,000 sensors and 3,200 video cameras across roughly 700 bridges and 100-plus tunnels citywide. Built on a digital-twin base map encoding more than 30 million objects (population, roads, utilities, facilities) by the city-owned Wuhan Cloud Computing Technology, it routes alerts through a three-tier municipal/district/community response chain and is now being extended to other cities across Hubei province.
📊 Impact
15,000 sensors and 3,200 cameras deployed across roughly 700 bridges and 100-plus tunnels; continuous monitoring of 200 designated waterlogging-prone points citywide; a digital-twin base map encoding more than 30 million objects (Wuhan municipal government, December 2024, self-reported).
🎓 Lesson
A monitoring platform this dense only reached full citywide scope in December 2024 — thoroughness of sensing and proof that it actually shortens disaster response are not the same thing yet.
