PUBLIC TRANSPORTATION IN BOGOTA: BENEFITS AND CHALLENGES Eduardo Behrentz Department of Civil and Environmental Engineering Universidad de los Andes (Bogota, Colombia) Sustainable Smart Cities Symposium The University of Alabama at Birmingham - June 2014 Facultad de Ingeniería Universidad de Los Andes
BOGOTA IN NUMBERS • Founded in 1538. • Colombia´s capital and largest city. • 8 million people in 400 square kilometers (200 hab/ha). • 90 billion U.S. dollars GDP ($11,000 p.c).
15 million daily trips and 70 million VKT. • ~ 15,000 road kilometers (quality). • CO2 emissions = 20 million tons per year. • 1.5 million vehicles (60,000 taxis, 20,000 transit buses, 400,000 motorcycles) – 150 vehicles (per 1,000 p).
THE SOLUTION: INTEGRATED TRANSPORTATION SYSTEM • Central planning. • Single authority. • Unified fare collection. • Mode integration. • No competition within the market.
This requires either publicly owned fleets or heavily regulated markets
Impact on PM2.5 Emissions • > 50% Reduction
FINAL REMARKS • Improving public transportation is the single most effective measure to reduce air pollution and its harmful effects (in urban centers of the developing world). • It is also the best strategy to avoid usage of private vehicles (far better than restrictive measures). • Growing Latin American cites must seize the opportunity of high shares of public transportation – The window is closing rapidly and there is no easy way back. • Beware of the motorcycle – Bad service leads to its massive use (Asia is losing the battle).
