TransMilenio

The TransMilenio is a bus rapid transit system that serves Bogotá, Colombia. Its main stretch runs through the north side of the city, through Av. Caracas, Calle 80, Autopista Norte, and Av. Jiménez. The system opened to the public in November 2000 covering Av. Caracas, and the other routes were added gradually afterwards.

Based on the successful model used in Curitiba, Brazil, the TransMilenio consists of numerous elevated stations in the center of a main avenue, or "troncal". Users pay in the station and await the arrival of the bus, whose doors open in time to the sliding glass doors of the station. Two dedicated lanes are used on either side of the stations in order to allow express buses to pass the station without stopping while other buses stop to allow passengers in or out.

As of December 2004, many important avenues in Bogotá are being rebuilt in order to be covered by the system. As part of this process, the streets are rebuilt in concrete and the TransMilenio stations are assembled. Among these avenues are Av. Suba and Av. NQS (Carrera 30).

The buses are diesel-powered, purchased from such manufacturers as the Brazilian company Marcopolo and German conglomerate Mercedes-Benz. The buses are articulated (split into two sections with an accordion-like rotating middle to allow for sharp turns) and have a capacity of 150 passengers.

As of April 2005, the fare was $1200 Colombian pesos for a single trip (about EUR 0.40 or USD 0.50). Cards use a magnetic "smart touch" system, and it is possible to buy multiple trips to be loaded on each card. Due to substantial percentage of errors when swiping the cards, some users are distrustful and purchase only one or two trips at a time. This problem has not yet been addressed with discounts for multiple purchases or public education campaigns, as has been recommended by urban planning consultants.

An additional set of regular buses, known as "feeders" (alimentadores, in Spanish), transport users 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 articulate and are green (regular TransMilenio buses are red). There is no additional cost associated with the use of feeder buses.

Although TransMilenio stations are handicapped-accessible by virtue of being elevated and ramps leading to the entrance, the alimentadores are normal buses without handicapped accessibility. However, a lawsuit by disabled user Daniel Bermúdez caused a ruling that all alimentadores must be handicapped accessible by 2004, but this has yet to occur.

Criticisms

Although most users will agree that the TransMilenio is a vast improvement over Bogotá's previous public transit system, especially in comparison with the chaotic systems in place in cities like Lima, Peru, there are a fair number of criticisms aimed at the TransMilenio system:

• Buses and stations are often packed to or beyond safe operating capacity, even during non-rush hour periods. This can be attributed to the small capacity (150 passengers) of the buses — modern metro trains can hold up to 1000 passengers, and buses in the Curitiba system hold up to 270 — as well as inadequate planning and response.
• The use of diesel buses instead of clean-burning natural gas or electric-powered light rail is best defined as an economic decision made to benefit TransMilenio, S.A., and not the best interests of the city. Diesel pollution has a much greater impact than at sea level in a high-altitude city like Bogotá (at 2,600 meters above sea level), not to speak of the noise pollution problems associated with diesel motors.
• Alimentadores continue to use obsolete engines that belt visibly black or brown exhaust fumes and do not drive in a safe or efficient manner.
• Many users complain about pickpocketing inside the buses, a problem which is made worse by the great extent to which the buses are packed.

Regardless of any problems, the system is considered by urban planners to be another shining example of how efficient, safe, and orderly public transit systems can be created without significant investment or disruption.
