Madrid built its smart city in one technocratic burst and then watched it become political. A cluster of 2014 platforms — an integrated services system, an open-data portal, an all-electric bike-share and emissions-priced parking — was followed by a civic-tech export copied worldwide and, later, a low-emission zone fought over in the streets and the courts.
The atlas documents 8 projects in Madrid, the earliest dating to 2014: 1 scaled back, 7 still running without a verdict. Every entry carries an evidence grade — the strongest here is peer-reviewed (2 entries) — and links its sources.
Three entries that show what Madrid is actually doing.
Computed from the 8 entries below — a profile, not a score.
Madrid's smart city arrived almost all at once, in 2014. In a single technocratic push the city stood up the MiNT platform, built on IBM software to manage its outsourced urban services — cleaning, waste, trees, lighting — from one shared inventory of millions of geolocated assets; opened the datos.madrid.es open-data portal, now one of Spain's largest municipal catalogues; launched BiciMAD, among the first big-city bike-shares to run entirely on e-bikes from day one; and rewired on-street parking with the SER inteligente, which reads a car's licence plate and prices the space by its emissions band.
The next year brought Madrid's most-copied idea and its clearest cautionary tale. Under Mayor Carmena, Decide Madrid (2015) let residents file proposals, debate and steer participatory budgets — and its open-source engine, CONSUL, was reused by more than 250 institutions across dozens of countries, a genuine global civic-tech export. Yet at home almost no citizen proposal ever cleared the vote threshold, and the incoming administration pared the platform back after 2019 — a reminder that the software travelled better than the participation.
From 2018 the story moved to the air, and turned political. Madrid Central barred the most-polluting cars from the centre with camera enforcement, cutting NO2 at central monitoring stations in peer-reviewed studies — then became a battleground: a new mayor suspended it, courts reinstated and annulled versions, and it relaunched as the citywide 'Madrid 360' zone, its legal fight running to 2026. Underneath the politics ran steadier infrastructure: the air-quality monitoring network whose 24 stations trigger the city's high-pollution protocol, and EMT's real-time bus, open-data and contactless-payment layer (contactless from 2019).

Plans and announced trajectories — not yet documented results.
Madrid's coming years are less about new platforms than about defending and connecting the ones it has: keeping the Madrid 360 low-emission zone alive through its legal challenges, folding its air-quality and open-data feeds into everyday decisions, and deciding whether Decide Madrid becomes a living channel again or a well-travelled piece of software the city itself stopped using. Its record is a caution and a template at once: the technology was the easy part; the politics decided what survived.
Where Madrid appears in the atlas's own analysis.
Three cities the atlas reads next to Madrid — the reason first, then the entries it rests on. Chosen by hand from the Madrid threads below, not counted out of them.
The closest like-for-like pair in the atlas: two Spanish cities of comparable weight that built rival versions of the same four things — an open-data portal, a participation engine, a camera-enforced low-emission zone, a bike-share.
The two capitals that ran the same programme four times over — an open-data portal, a citywide participatory budget, a politically contested low-emission zone and a docked bike-share — each within a few years of the other.
Two reference air networks feeding a real pollution protocol, and two transit operators that built the shared-mobility app themselves rather than buying one — the same two instincts, a thousand kilometres apart.
Every editorial link from Madrid'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.
