Bus-Rapid Transit Systems as Cost- Effective Transportation Alternatives: The Case of TransMilenio, Bogotá

Driven by economic growth and rural displacement, the population of Bogotá, the capital of Colombia, grew dramatically throughout the 1990s. This rapid growth put a strain on existing transportation services, resulting in heavy congestion, excessive travel times, and elevated levels of noise and air pollution. Inner city trips—averaging an hour and 10 minutes—took place mainly by private vehicles that used 95 percent of available road space and were involved in over 52,764 accidents in 1998.
