TransMilenio is a bus rapid transit (BRT) system that serves Bogotá, the capital of Colombia, and Soacha, a neighbouring city. The system opened to the public in December 2000. As of 2024, 12 lines totalling 114.4 km (71 mi) run throughout the city.[1] It is part of the city's Integrated Public Transport System (Sistema Integrado de Transporte Público [SITP]), along with the urban, complementary and special bus services operating on neighbourhood and main streets.
TransMilenio consists of several interconnected BRT lines, with raised floor stations in the center of a main avenue, or "troncal". Passengers typically reach the stations via a bridge over the street. Usually four lanes down the center of the street are dedicated to bus traffic. The outer lanes allow express buses to bypass buses stopped at a station.[citation needed]
As of the 4th quarter of 2023, 1,836 buses on average were circulating on the trunk line system. An additional set of 869[2] regular buses, known as "feeders" (alimentadores in Spanish), carry passengers from certain important stations to many different locations that the main route does not reach. Unlike the main TransMilenio buses, feeders operate without dedicated lanes, are not articulated and are either green or blue (regular TransMilenio buses are red). There is no additional fare to use the feeder buses.
There are 27 bicycle parking facilities in main TransMilenio stations with 7,351 parking spaces to facilitate cyclists using the system.[1] Eight BRT corridors were certified in 2013 to meet the BRT standard with excellence: Autonorte and Caracas silver, Americas, Calle 80, Eldorado, NQS and Suba gold.[3]
