The buses ran from December 2000. One fare card shared with the city's other buses reached every station only in December 2015, and a single control centre opened only in March 2026.

TransMilenio opened in December 2000 under mayor Enrique Peñalosa — articulated buses in dedicated median lanes, enclosed pre-paid stations, level boarding — a model that later systems, Mexico City's Metrobús among them, were built on. The data layer came later and in pieces: one fare card shared with the city's other buses, TuLlave, replaced TransMilenio's own contactless cards station by station from September to December 2015, the fleet-control system began a phased renewal in January 2024, and a single control centre for operations & security opened in March 2026, the first time in the system's history that operations and security worked from one place. TransMilenio S.A., the district company, is also the managing entity for Bogotá's wider SITP bus network and TransMiCable, and it publishes its static GTFS timetable feed with no licence attached. Paying at the turnstile with a contactless bank card or phone has been piloted since January 2025 and ran at two stations in January 2026, without TuLlave's free transfers. The TransMilenio trunk on Carrera Séptima, revoked in 2020, 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; TransMilenio figures a councillor published in February 2026 put trunk evasion at 13% and its 2025 cost at about COP 265 billion.
🎓 Lesson
Bogotá built the corridor first and the control room last. Concrete, prepaid stations and level boarding delivered metro-scale throughput; unified ticketing arrived only in 2015, an integrated control centre only in 2026 — by which time crowding, fare evasion and riots had already set the system's public reputation. Throughput is not the same as legitimacy.

Vol. 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.

Vol. 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.

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.

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.

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.
