Chongqing's traffic police fused 1.5 billion records from a dozen departments into a signal-control brain for just 51 intersections — and say it moved 2024's Golden Week rush hour 50 minutes earlier.

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.

In late September 2024, Chongqing's traffic police stood up a data-fusion system for the city's central urban core, pulling together roughly 1.5 billion records from 12 municipal departments and 60 data categories to run automated signal retiming, 11 roadside display screens and targeted patrol dispatch across 17 roads and 51 intersections. Police reported that during the 2024 National Day holiday the evening rush-hour peak ended nearly 50 minutes earlier than the year before, coinciding with the city's first holiday week without a major long-duration jam or an expressway fatality; within the system's first two months it also flagged 1,000+ unlicensed-driving cases through cross-referenced data rather than roadside stops. All figures are police-reported; no independent traffic study was found.
📊 Impact
17 roads / 51 intersections in the central urban core; ~1.5 billion records fused from 12 departments and 60 data categories; evening rush-hour peak ended ~50 minutes earlier during the 2024 National Day holiday versus the prior year, with zero major long-duration jams and zero expressway fatalities that week; 1,000+ unlicensed-driving cases flagged in the system's first two months (all police-reported).
🎓 Lesson
A traffic 'brain' built from 1.5 billion fused records still only reaches 51 intersections — data integration scaled faster than physical rollout.
