Santiago is an urban area of about 6.66 million people, spread across forty comunas, with no government of its own. There is no metropolitan municipality and no metropolitan police force; there is a province of thirty-two comunas, a region of fifty-two, and a national state that runs most of what matters. That gap decides the city's whole record. Its strongest instruments — a vintage-tiered driving ration, a published fare-evasion index, two metro lines whose trains were built without a driver's cab, a raw-water reserve holding thirty-seven hours of supply — belong to national ministries, a state rail company or a private concessionaire. What is left to the comunas, each on its own budget, fragments accordingly: a bike share that has retreated from fourteen comunas to five, security drones in the richest one, and an open-data catalogue covering a single comuna of the forty.
The atlas documents 10 projects in Santiago, the earliest dating to 1992: 1 with a documented success, 1 documented failure, 1 scaled back, 7 still running without a verdict. Every entry carries an evidence grade — the strongest here is peer-reviewed (1 entry) — and links its sources.
Three entries that show what Santiago is actually doing.
Computed from the 10 entries below — a profile, not a score.
Santiago began rationing driving before most cities began measuring it. The restricción vehicular of 1992 was, on the reading of a Review of Economic Studies paper, the earliest scheme anywhere to ration by a vehicle's vintage rather than uniformly: catalytic cars carrying the sello verde lose two plate digits a day, older ones lose four and are barred from the Américo Vespucio ring outright. Five years later the first decontamination plan set up what is now the Gestión de Episodios Críticos, and the two were wired together — an air-quality reading adds digits to the ban. Chile thus built the classification layer and the trigger layer that Delhi's odd-even scheme still lacks, and did it a generation early. Enforcement, then and now, is Carabineros reading plates at the kerb.
The next instrument was the fare card, and it arrived attached to a disaster. bip! launched in February 2007 with the Transantiago restructuring, tendered to a consortium of four banks with Sonda and Falabella, and one tap has bought up to two transfers within two hours ever since. What makes it unusual is not the card but the counting: the transport directorate DTPM runs a semiannual survey of how many bus boardings are never paid for, under a method fixed by ministerial resolution, and publishes the number even when it reads 45.8 percent. It also publishes origin-destination matrices built from those taps — and states on their face that they exclude the journeys nobody paid for.
Then the rivers intervened. Santiago drinks Andean water, and an Andean storm can drive raw turbidity in the Maipo far past what a treatment plant can take: February 2013 recorded 380,000 NTU against a treatable ceiling near 20,000 and cut supply to 1,128,044 customers, April 2016 reached 79,000 NTU across 29 comunas, February 2017 hit 33. The concessionaire's answer was storage. Six raw-water tanks at Pirque holding 1.5 million cubic metres entered service in December 2019, lifting the city from about eleven hours of production without a river to thirty-seven. CIPER had already shown customers paid for an earlier round of the same works through a tariff rise.
The years around 2017 pulled in two directions at once. Metro opened Line 6 in November 2017 and Line 3 in January 2019 with CAF trains that have no driver's cab at all, only a concealed console for manual recovery — the rare case in this atlas where a driverless label has held for eight years, because there is no seat from which an attended service could be run. In the same season Las Condes put two municipal drones over its plazas and won the Supreme Court's blessing when residents sued, while a national rule ordering smart electricity meters into every home collapsed: Parliament had just moved ownership of the meter from the household to the distributor, the tariff then billed households to rent it, and in April 2019 the energy minister made the whole thing voluntary.

Plans and announced trajectories — not yet documented results.
Santiago's next decade is being decided by who is allowed to own things. The Ley CATI would give the plate ration its missing third layer — automated camera enforcement — and the transport minister expected it in force during 2026; a bill obliging distributors to fit smart meters at their own cost cleared a Chamber committee in January 2026, seven years after the first attempt died over the same question. The measured trends are real: unpaid bus boardings have fallen five halves running, to 34.9 percent, and hours spent in fine-particulate episodes fell 66 percent over a decade. But the counterweights are equally real. The Pirque reserve was overrun once, on 24 June 2023, when 280 millimetres of rain in four days halved its autonomy and 1,304,857 customers lost supply anyway. The industrial lever inside the episode regime has quietly emptied itself: by May 2026 the environmental regulator listed one of fifty-five affected plants as obliged to stop, the rest having met their targets. And nothing has emerged to close the gap in the middle. The bike share left the city's own central comuna in March 2025, announced by a message in the app, because no comuna pays for it and so no comuna can insist. The Metropolitan Regional Government's entire contribution to Chile's national open-data portal remains two datasets of tender notices uploaded in 2015. A city that measures itself this carefully still has no one whose job is the whole of it.
Where Santiago appears in the atlas's own analysis.
Two cities the atlas reads next to Santiago — the reason first, then the entries it rests on. Chosen by hand from the Santiago threads below, not counted out of them.
Where the playbook went: Santiago built its electric bus fleet on the model Shenzhen proved first, and both then ran metros whose newest trains leave no room for a driver at all.
Mirror rulings on the same technology: a Buenos Aires court declared face matching unconstitutional where Chile's Supreme Court let the surveillance stand — and the same bike-share operator is paid in one city and pays in the other.
Every editorial link from Santiago's entries into another city, strongest first. Each one is a statement about two projects, not about two cities — the three above are the ones the atlas is willing to make at city level.
