Chongqing - As cities around the world grapple with natural disasters, industrial risks, and public emergencies, Chongqing is turning heads with its tech-driven approach to urban safety. 

At a recent press conference, a city official revealed that Chongqing's digital emergency management is becoming a center for urban safety governance.

The platform uses a five-color risk management system to classify extremely high to low hazards, dynamically tracking 38,000 risk points across 41 categories. The red, orange, yellow, blue, and green colors represent extremely high to low risk levels. It integrates 1.2 million survey records into a unified geographic information system and delivers alerts on 25 types of risks—including natural disasters, industrial accidents, and public safety threats—in seconds.

Leveraging AI, it simulates and analyzes disasters using a unique intelligent model that integrates hazard factors, such as rainfall, earthquakes, and human activities, with exposed elements like infrastructure and ecosystems, enabling accurate risk identification, visualization, and automatic generation of risk trend maps.

The platform is powered by AI engines and connects historical data with emergency plans to deliver one-click response strategies. Digital simulation models for five disaster types—including river floods and hazardous chemical leaks—advance disaster management from experience-based to predictive.

It also integrates multiple systems to build a 3D command network, featuring 100 drones, extensive ground surveillance coverage, and 7,000 individual devices equipped with Beidou positioning—a Chinese satellite navigation system—enabling coordinated operations across air, ground, and space. 

Meanwhile, a smart emergency app enables instant information flow, 3D disaster visualization, and precise resource dispatch for timely awareness, clear visibility, rapid access, and effective response.
