🤖 AI-generated city profile, summarising the source-checked entries below — how this works
Nanjing's smart-city work sits almost entirely in the machinery of enforcement and dispatch rather than in showcase districts: an environment bureau that watches 3,976 permit holders and 36,000 heavy diesel trucks from one screen, a flood platform that texts district officials to pre-lower river levels before a storm, and a signal-timing office that buys its evidence from a ride-hailing company's floating-car data. Most of it is bolted onto systems the city already ran — parking meters, bike quotas, e-bike sales counters, metro signalling — which is also why so many of the published numbers describe process (fewer site visits, faster work orders) rather than outcomes. Where the city does claim a technical first, its own wording is careful: Line 7's trains are described as having the capability to run without a driver, not as running without one.

Three entries that show what Nanjing is actually doing.
Before this, Nanjing lowered river levels for a storm by dropping every pump forebay to its design minimum. Now 6,000 outfalls report red, yellow or blue, and the system texts the district that has to act.
One screen watches 3,976 permit holders, 36,000 diesel trucks and 113 air stations, and the bureau's proudest number is a reduction: inspectors went to fewer sites, not more.
Jiangsu's first metro line designed to run without a driver opened in three pieces over three Decembers. Nanjing's own wording never quite closes the loop: the trains have the capability to run driverless.

After ten years the city app reports 11.25 million real-name registered users. Nanjing has 9.58 million residents — which tells you the counter measures sign-ups, not use.
🇰🇷 Seoul: Ttareungyi Public Bike-ShareCity-run against licensed private: Seoul owns 45,000 bikes, Nanjing caps three operators at 305,000 and publishes their scores.
🇯🇵 Tokyo: LUUP Shared E-Scooters & E-Assist BikesBoth responded to micromobility casualties; Tokyo through operator rules and Nanjing by making every battery traceable after a fatal fire.
🇺🇸 Denver: Micromobility Open Data IntegrationBoth regulate through a live data feed rather than a ban — and both make the operator's own numbers the condition of the permit.
🇨🇳 Shanghai: Flood & Typhoon Command SystemThe Yangtze delta's two flood command systems, one organised around typhoons at the coast, the other around meiyu rain inland.
