Transmilenio is a BRT system that emphasizes priority for rapid movement of buses by securing segregated carriage way for buses. It uses both articulated buses with a carrying capacity of between 150 and 185 and bi-articulated buses with a carrying capacity of around 270 passengers. These buses are supplemented by feeder buses. The Transmilenio system transported around 1.25 million passengers per day when launched in 2000.
Among the benefits of BRT systems the following can be mentioned:
1) modal integration with other modes
2) rapid boarding and inteligent ticketing
3) high carrying capacity
4) decrease congestion
5) implementation cost is a fraction of a metro.
