Bogotá writes rules with real legal force and then struggles to keep the instruments behind them working. An air-quality band fixed by resolution can shut down boilers across a whole district; a petition that goes unanswered for fifteen days is a disciplinary matter; a reading above 22 cubic metres on a household water meter automatically added a surcharge to the bill. But the camera fleet the city owns was 23% dark in May 2026, two thirds of its open-data catalogue went a year without an update, and its bicycle register — compulsory since 2022 — still covers well under half the bikes on the street. The exception is the thing nobody expected to be rigorous: the cable car to Ciudad Bolívar was evaluated against a control neighbourhood, and published its own null results.
The atlas documents 13 projects in Bogotá, the earliest dating to 1997: 3 with a documented success, 1 scaled back, 9 still running without a verdict. Every entry carries an evidence grade — the strongest here is peer-reviewed (4 entries) — and links its sources.
Three entries that show what Bogotá is actually doing.

It began with a decision to build buses instead of a railway. TransMilenio opened in December 2000 under mayor Enrique Peñalosa — articulated vehicles in dedicated median lanes, enclosed prepaid stations, level boarding — and became the template that BRT systems from Mexico City to Dakar were measured against; a peer-reviewed measurement later put throughput on the busiest section at about 43,000 passengers an hour in one direction. Peñalosa shelved competing metro plans to pay for it. Two years earlier he had also introduced pico y placa, barring cars from the road one weekday a week by the last digit of the plate. Neither began with much of a data layer: the busway ran for fifteen years before a single fare card covered all its stations.
The instruments arrived one at a time, and mostly not from the transport side. The district environment secretariat had been running the RMCAB air-quality network since 1997. The 123 emergency line merged the separate police, fire, health and traffic numbers in May 2007, and moved into a purpose-built command centre in 2016. The TuLlave card launched with the city bus system in 2012 and only reached every TransMilenio station in September 2015. The open-data portal followed in 2017 and the bicycle register in 2018 — the same December that TransMiCable began carrying Ciudad Bolívar down the hillside to the trunk network.
Then Bogotá started attaching consequences, and charging for exemptions from them. From 22 September 2020 a driver could buy their way out of pico y placa: a permit priced by the vehicle's value, emissions and city of registration, sold through a plate-linked register, with every peso earmarked for the fund that subsidises transit fares. It has raised about 488 billion pesos a year, and the peer-reviewed evaluation found the buy-out made traffic roughly 9% slower while leaving the city better off, because road access moved from richer drivers to middle-income ones. Registration of a bicycle became compulsory from 2 January 2022 — though the announced sanction is only a police warning. The bike share arrived the same year, not bought but tendered as economic use of public space, paid for in bicycle parking.
The last three years have been about thresholds and their limits. A joint environment-and-health resolution fixed the IBOCA index bands in December 2023, and on 25 January 2024 the south-west of the city went into Alert Phase 1 — boilers restricted on weekdays, maintenance of emission-control systems barred. From 11 April 2024 the water utility cut supply to nine rotating zones for a year after the Chingaza reservoirs fell to about 16.5%, and on 1 February 2025 the city abolished the discounted transit fare for poor, elderly and disabled riders, replacing it with free trips preloaded onto their cards. TransMilenio finally opened a single control centre for operations and security in March 2026, twenty-five years after the first bus, and the metro Peñalosa shelved passed 80% construction.

Three questions run through everything Bogotá has built, and each is about whether the instrument behind the rule actually works. The first is maintenance. The Contraloría found roughly 45% of the district's 5,824 cameras out of service under the 2021-2023 maintenance contracts, with duplicate payments and charges for servicing cameras that were already dead; 1,367 were still dark in May 2026, while the city added 1,676 new feeds. The same pattern shows in the data: the portal states an open-licence rule on its own front page, citing national law — further than São Paulo, Shanghai or Bangkok go — and 99 of its 1,900 datasets still carry licences that rule forbids, with 64 more carrying none, and two thirds of the catalogue untouched for a year. The second is who carries the risk. Three arbitration tribunals have found for the private fare-collection concessionaire, one of them placing responsibility for fare-evasion control on TransMilenio S.A. rather than on the collector — which left the public operator with a loss put at around 295 billion pesos for 2025. The third is what happens in 2028, when the metro is due to open under a contracted grade of automation that no source has yet confirmed will run without staff aboard, and a separate tender replaces TuLlave with a system meant to cover metro, bus and regional rail together.
Where Bogotá appears in the atlas's own analysis.
Three cities the atlas reads next to Bogotá — the reason first, then the entries it rests on. Chosen by hand from the Bogotá threads below, not counted out of them.
Both publish the numbers that undercut their own programmes — a tree count that turns out to be mostly shrubs, a bike register that recovers more bicycles than it ever registered — and both measure air they have little power to clean.
The densest pair in the atlas: cable cars up comparable hillsides, an electrified bus fleet against a bike-share, and two air thresholds that bind — Mexico City's by itself, Bogotá's only once a committee agrees.
Colombia's two cable-car cities, and the reason one is better evidenced: Bogotá's later gondola came with a comparison district, Medellín's original never had one — and both electrified their bus corridors in the same years.
Every editorial link from Bogotá'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.
