Lisbon's first entry in the atlas is PGIL, the city's data backbone since 2017: a platform that pulls real-time feeds from around 40 municipal and partner systems — traffic, bike-share and parking use, waste-bin fill levels, pollution and noise — into one operations dashboard. Rather than sitting idle as a monitoring tool, that same data stream now powers downstream work: the INESC-ID-built iLU mobility-planning tool and an EU-co-financed university lab piloting micro-mobility and crowd-management tools with local researchers.
The atlas documents 7 projects in Lisbon, the earliest dating to 2008: 1 scaled back, 6 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 Lisbon is actually doing.
Computed from the 7 entries below — a profile, not a score.
Lisbon's smart-city story starts with governance, not sensors. In 2008 the city became the first European capital to hand residents an online vote over city capital spending, run through lisboaparticipa.pt and later by SMS. The data layer came later, and in two separate pieces: Lisboa Aberta began publishing municipal datasets in 2016, and the following year PGIL went live as the operations dashboard that pulls roughly 40 of those same feeds — traffic, bike-share, parking, waste, pollution, noise — into one screen for city staff. The two platforms share a brand, "Lisboa Inteligente," but not a system; a 2023 strategy plans to eventually fold them together. GIRA, the city's docked bike-share, opened the same year as PGIL, with GPS-tracked bikes and live app availability feeding straight into that dashboard.
The next wave built out sensing rather than dashboards. An 80-station network went in during 2021 to track air pollutants, noise, weather and hourly traffic citywide, and from 2022 a ten-sensor flood-monitoring pilot began watching water levels in flood-prone tunnels ahead of a €250M drainage master plan whose own first tunnel finished boring only in July 2025. Carris, the city's own bus and tram operator, modernised in parallel: a ~€3.4M platform upgrade completed in October 2022 gave every vehicle GPS tracking, feeding first Google Maps and later the operator's own app.
What the last few years mostly show is Lisbon publishing its own shortfalls. Carris called its real-time vehicle feed "public, not free" and gated an independent tracking app out of it the same month the GPS platform went live — a restriction a digital-rights association says breaches Portugal's own open-data law. GIRA's fleet crisis surfaced in May 2025, when reporting found barely a third of the roughly 2,000 bikes the app promised were actually on Lisbon's streets, three years after the operator's own budget cut planned investment by about 75%. And the participatory-budget platform that made Lisbon a European first in 2008 has sat dormant since 2021; a 2025 attempt to relaunch it under a smaller model was withdrawn from a vote for lack of consensus, and as of April 2026 it remained stalled with no announced restart date.

Editorial links between Lisbon's own entries — the city as a system, not a list.
Plans and announced trajectories — not yet documented results.
What's next for Lisbon is mostly about whether the city closes gaps its own reporting has already found. Automatic camera enforcement for the city's decade-old low-emission zone was budgeted for 2026 but had no confirmed live date as of the most recent reporting; the drainage master plan's second tunnel is not due until 2029; and Carris has promised a rebuilt GIRA app for 2026 after years of reliability complaints. Whether any of that lands on schedule is, on this record, an open question.
Where Lisbon appears in the atlas's own analysis.
One city the atlas reads next to Lisbon — the reason first, then the entries it rests on. Chosen by hand from the Lisbon threads below, not counted out of them.
The same idea with opposite endings: a city-run platform that ingests what the administration holds. Lisbon's is still centralising data; the operating system Columbus built around it is not.
Every editorial link from Lisbon'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.
