The buses ran from December 2000. A contactless card reached every station only in September 2015, and a single control centre opened in March 2026, twenty-five years after the first bus.

Scale🏙️ City-wide

FundingFares plus a district subsidy — TransMilenio's general manager says the District covers about half the fare, set at COP 3,550 for 2026; infrastructure is publicly built, while buses and fare collection are run by private concessionaires.

TransMilenio opened in December 2000 under mayor Enrique Peñalosa — articulated buses in dedicated median lanes, enclosed pre-paid stations, level boarding — the template that BRT systems from Mexico City to Dakar were measured against. The data layer came later and in pieces: the Tullave contactless card reached every TransMilenio station only in September 2015, the GPS fleet-control system began a phased renewal in 2024, and a single control centre for operations & security opened in March 2026, twenty-five years after the first bus. TransMilenio S.A., the district company, is also the managing entity for Bogotá's wider SITP bus network and TransMiCable, and it publishes static and real-time GTFS feeds with no licence attached. The Carrera Séptima trunk promised for decades is still unbuilt, and the metro Peñalosa shelved to pay for the busway is now more than 80% complete.

📊 Impact

A peer-reviewed measurement put throughput on the busiest trunk section at about 43,000 passengers per hour per direction, with a practical ceiling near 48,000 at 150 passengers per bus (Hidalgo, Lleras & Hernández, Research in Transportation Economics, 2013). Trunk fare evasion fell from 29.6% in 2022 to 13.1% in 2024 on figures cited in a Bogotá council debate, with losses still above COP 100 billion per half-year; a February 2026 council item put the 2025 cost above COP 265 billion.

🎓 Lesson

Bogotá built the corridor first and the control room last. Concrete, prepaid stations and level boarding delivered metro-scale throughput within two years; unified ticketing arrived after fifteen, an integrated control centre after twenty-five — by which time crowding, fare evasion and riots had already set the system's public reputation. Throughput is not the same as legitimacy.

↗ Hidalgo, Lleras & Hernández — capacity measurement (Research in Transportation Economics, 2013, peer-reviewed)Published 2013 archived copyVol. 39(1):139-142. Abstract states 'actual throughput of 43,000 passengers hourly per direction with average bus occupancy of 150 passengers' and a practical capacity of '48,000 passengers per hour per direction with its existing infrastructure and 150 passengers per bus' (35,000 at 110 passengers per bus). Sole basis for the capacity figures; the entry attributes them rather than claiming any world record. Note the lead author was closely associated with the system's evaluation literature.

↗ Tsivanidis — welfare evaluation (American Economic Review, 2026, peer-reviewed)Published February 2026Vol. 116(2):418-63. Establishes that an independent economic evaluation exists and that conventional commute-time benefit calculations capture only about half the total welfare gain, with 'distributional impacts are modest'. No single headline number is quoted in the entry because the paper's results are model-based.

↗ Alcaldía de Bogotá — Integrated Control Centre opens (17 March 2026)Fetched successfully. Establishes the control centre is new, not original: 1,200 m2, 209 workstations, the first time in the system's 25-year history that operations and security run from one location; supervises up to 4 million daily trips and more than 10,700 buses; roughly 2,700 fixed cameras plus over 36,900 onboard; AI video analytics and onboard GPS; more than 40 million data records processed per day; coordinates Troncal, TransMiZonal and TransMiCable — the evidence that TransMilenio S.A.'s remit extends beyond the BRT.

↗ TransMilenio — GTFS-realtime feed page (operator)Fetched successfully. Lists three GTFS-realtime endpoints (vehiclepos.pb, serviceAlerts.pb, tripupdate.pb). Carries no licence or terms-of-use statement of any kind — the basis for 'no licence attached' in the snippet.

↗ TransMilenio open data portal — static GTFS (operator)Published 23 July 2025Static GTFS document dated 2025-07-23 on the operator's ArcGIS Hub portal, alongside 17 SITP datasets on the Bogotá open data portal. Established via search index; the individual document page was not fetched directly. First publication year of the GTFS feed could not be established and is not claimed.

↗ TransMilenio — fleet control system modernisation (operator, 2024)States a gradual renewal and modernisation of the fleet control system beginning 3 January 2024, enabling real-time management of the trunk and dual fleet, with GPS equipment on each trunk vehicle.

↗ Tarjeta TuLlave — dates of the fare-card rollout (Wikipedia ES, tertiary)Sole source located for the sequence: collection concession awarded to Recaudo Bogotá S.A.S. on 16 June 2011 for 16 years; the card launched with the SITP in January 2012; unification of payment onto TuLlave across all TransMilenio stations began 2 September 2015. Tertiary source, used because the operator's own TuLlave page returns HTTP 403. The September 2015 date is the load-bearing one for the 'data layer came later' framing and should be re-checked if a primary source becomes reachable.

↗ Infobae — trunk fare evasion figures (24 July 2025)Fetched successfully. Carrying sentence: 'La evasión en el componente troncal de TransMilenio pasó de 29,6 % en 2022 a 13,1% en 2024', and 'La evasión sigue generando pérdidas superiores a $100.000 millones de pesos por semestre'. The article attributes the figures to councillors Cristina Calderón Restrepo and María Clara Name in a Bogotá council debate, not to a TransMilenio publication — so these are council-cited, not audited, numbers.

↗ Concejo de Bogotá — 2025 cost of fare evasion (12 February 2026)Council item headlined 'La evasión en TransMilenio le costó a Bogotá más de $265 mil millones en 2025'. FETCH FAILED: HTTP 503. Search-index summaries additionally report trunk evasion of about 15% at the close of 2025, rising 1.29 points in the second half after metro works forced the removal of automatic doors and access control on the Caracas corridor — that finer detail is NOT carried in the entry because it could not be verified sentence-level.

↗ Wikinoticias / NBC News — the March 2012 riots9 March 2012: blockades at all portales, stations damaged on Caracas (Calles 39, 45, 72 and Marly), Calle 80 and Las Américas; Marly station destroyed and looted; 28 detained; the Procuraduría General de la Nación named overcrowding and fare increases as triggers.

(Revista Ciudades, Estados y Política, Universidad Nacional de Colombia, 2017)Published 2017Fetched successfully. Academic critique of the contracting model: 388 km of exclusive bus lanes planned against 109 km completed by 2014; operators paid per kilometre run regardless of service quality; fares among the highest in Latin America relative to the minimum wage (11.6% vs 5.4% in Quito). Its further figures (2015 deficit, share of the fare going to operators, a 96% rise in accidents after a bus life-extension decision) are deliberately NOT carried in the entry — single-source and not independently corroborated.

↗ El Tiempo / Semana — the Carrera Séptima corridor, twice abandonedPublished 24 July 2020 · updated 25 July 2020Mayor Claudia López revoked the tender for the TransMilenio trunk on Carrera Séptima by administrative act, replacing it with a multimodal 'Corredor Verde'; Semana then reports the District revoking the Corredor Verde tender in turn (https://www.semana.com/politica/articulo/distrito-destapa-las-cartas-del-futuro-de-la-carrera-septima-en-bogota-tras-revocar-licitacion-del-corredor-verde-de-claudia-lopez/202431/).

Basis for 'more than 80% complete'. Establishes the metro as a separate project, deliberately not described in this entry beyond the historical link that Peñalosa shelved metro plans to build the busway.

↗ TransMilenio S.A. — '¿Qué es SITP?' (authority)Establishes the entity relationship required for scope: TRANSMILENIO S.A. is the managing entity (ente gestor) that plans, manages and controls the SITP, adopted as Bogotá's public transport system by Decree 309 of 2009.
