Warsaw is a city whose systems are checked from outside more often than most and contracted to fewer bidders than most. The Supreme Audit Office, NIK, has audited its traffic signals, its air-quality monitoring, its participatory budget and its heat planning; its bike-share and its signal network each went to the only firm that bid. What the record shows, again and again, is a city that counts its activity well and its results rarely: contacts to its 19115 line, rentals of its bikes, requests to its open data, online votes. The clearest outcomes sit where a rule meets its enforcement: camera cars that issue hundreds of thousands of parking notices a year, and a clean transport zone whose patrols took more than a year to issue a first fine.
The atlas documents 9 projects in Warsaw, the earliest dating to 2008: 9 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 Warsaw is actually doing.
Computed from the 9 entries below — a profile, not a score.
The record starts with a plan that came in short. In autumn 2008 the road authority ZDM switched on its integrated traffic management system, built by Siemens with EU money, at 37 junctions; the funding application had foreseen 158, and NIK found that bids for the other two areas had far exceeded the budget. Veturilo followed in 2012, a seasonal bike-share in 3 districts with 55 stations and 1000 bikes, and on 4 November 2013 the city opened Warszawa 19115, one contact centre reached by phone, portal, app, e-mail and chat, linked to more than 90 city units.
From 2014 the city put residents' choices online. The participatory budget shared out more than 26 million złoty in its first edition, when 166,892 people voted; the second edition set the record of 172,395. Since 2015 City Hall has published the live positions of buses and trams through an API that needs a personal key, with licence labels that do not agree. The heat network had left public hands in 2011, when the city sold 85% of its utility for 1.44 billion złoty, and between 2015 and 2017 its new owner, Veolia, put 2,500 substations under remote control from one dispatch centre. On smog days in December 2016 and January 2017 public transport was free, by the mayor's decision rather than a rule.
The years to 2022 were about contracts. A national law of January 2018 made the participatory budget compulsory. The signal network grew through an operator contract with Siemens that added five junctions a year. In 2020 Veturilo's eight-year tender drew one offer, of 160 million złoty, and was annulled as over budget, the year its operator filed for bankruptcy. The same year ZDM sent out the first camera cars to check payment in the paid parking zone, two of them at first, nine later. In 2022 the city switched on its own air sensor network, 108 devices across all 18 districts, and since 14 September 2022 the readings have been public; NIK assessed the city's monitoring positively in 2023.
Since 2023 the city has changed rules more than systems. From 6 April 2023 the 19115 app stopped taking anonymous parking reports. Veturilo was rebuilt for 2023 around GPS bikes on city-owned racks, with 3030 bikes and 4,910,240 rentals in its first season, again from a single bidder. On 1 July 2024 the Clean Transport Zone came into force over 37 km² of the centre, enforced by patrols with plate-reading cameras; the first fine came in late 2025. In 2024 the camera cars issued 384,700 parking fines. In December 2025 ZDM signed a six-year signal contract with Yunex, the only bidder, covering 479 junctions, and in June 2026 the participatory budget drew 55,366 voters, about 3 per cent of residents.

Plans and announced trajectories — not yet documented results.
The next tests are rules with dates on them. The clean transport zone tightens every two years until 2032, residents' exemption ends after 2027, and the one peer-reviewed study of its first year found no clear air-quality gain and asked for follow-ups that correct for the weather. Veolia's second remote-control phase is due to cover 5,814 substations by the end of 2027, and nobody has yet separated what the data did from what the new pipes did. Veturilo's contract runs until 2029, with no winter service expected before then, and the new signal contract offers AI and a digital twin only as options its operator will propose and test.
Where Warsaw appears in the atlas's own analysis.
Three cities the atlas reads next to Warsaw — the reason first, then the entries it rests on. Chosen by hand from the Warsaw threads below, not counted out of them.
Two cities whose clean-air zones stopped short of full force, one with cameras that never charged and one with patrols that barely fined, and whose bike hire was rebuilt around GPS bikes under a public contract.
Two cities where continuity is the question: a participatory budget that lapsed beside one a national law keeps alive, and GPS bike-shares run by a city company or by a private contractor.
Two cities that test what a document promises: open-data portals whose licence labels are clean or contradictory, and station bike-shares that reached the end of a fixed contract term.
Every editorial link from Warsaw'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.
