TransMilenio 3.57

TransMilenio is a bus rapid transit (BRT) system that serves Bogotá, the capital of Colombia. The system opened to the public in December 2000, covering Av. Caracas and Calle 80. Other lines were added gradually over the next several years, and as of 2012, 12 lines totalling 112km run throughout the city, making it one of the world's largest bus rapid transit systems.Inspired by Curitiba's Rede Integrada de Transporte (Integrated Transportation Network), TransMilenio consists of several interconnecting BRT lines, each composed of numerous elevated 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. There are both express and local buses, the latter stopping at every station to pick up passengers. The outer lanes allow express buses to bypass buses stopped at a station.Users pay at the station entrance using a smart card, pass through a turnstile, and wait for buses inside the station, which is typically 5 m wide. The bus and station doors open simultaneously, and passengers board by simply walking across the threshold. Like in a subway system, the elevated station platform and the bus floor are at the same height.The buses are diesel-powered, purchased from such manufacturers as the Colombian-Brazilian company Marcopolo-Superior, German conglomerate Mercedes-Benz, and Swedish companies such as Volvo and Scania.
