Calming Traffic on Bogotá's Killing Streets
Jon Cohen

With humor, education, and tough laws, this Colombian city has dramatically reduced traffic injuries and deaths
Long branded as one of the world's most dangerous cities, Bogotá, Colombia, has won plaudits for cutting its murder rate by more than 70% during the past decade. But this city of 7 million people has received far less attention for a dramatic decline in a more common danger that plagues urban areas everywhere: traffic-related injuries and deaths.

With a combination of innovative education campaigns, an overhaul of its public transportation system, strict law enforcement, and redesign of streets and highways, Bogotá has made moving from place to place safer and more efficient. "In 1997, everything was a mess and we were losing the battle," says Dario Hildalgo, a transportation engineer from Bogotá who is now with the World Resources Institute in Washington, D.C. "To solve the problems, we needed a miracle. The miracle happened."

Mark Rosenberg, the former head of injury prevention at the U.S. Centers for Disease Control and Prevention in Atlanta, Georgia, says Bogotá is a model for the world. "Bogotá is not unique in having this problem, but it is unique in solving it," says Rosenberg, who now heads the nonprofit Task Force for Child Survival and Development in Decatur, Georgia.

From living hell to living well: A radical campaign to return streets from cars to people in Colombia's largest city is now a model for the world

On a clear, cloudless afternoon, Enrique Peñalosa, former mayor of Bogota, leaves his office early in order to pick up his 10-year-old son from school. As usual, he wears his black leather shoes and pinstriped trousers. As usual, he is joined by his two pistol-packing bodyguards. And, as usual, he travels not in the armoured SUV typical of most public figures in Colombia, but on a knobby-tired mountain bike.

Mr. Peñalosa pedals through the streets of Santa Barbara in Bogota's well-to-do north side. He jumps curbs and potholes, riding one-handed, weaving across the pavement, barking into his cellphone with barely a thought for the city's notoriously aggressive drivers.

On most days, this would be a radical and perhaps suicidal act. But today is special.

Ever since citizens voted to make it an annual affair in 2000, private cars have been banned entirely from this city of nearly eight million every Feb. 1. On Dia Sin Carro, Car Free Day, the roar of traffic subsides and the toxic haze thins. Buses are jam-packed and taxis hard to come by, but hundreds of thousands of people have followed Mr. Peñalosa's example and hit the streets under their own steam.

The sleek red bus zooms out of the station in northern Bogotá, a futuristic symbol of an (almost) transformed city. Nearby, thousands of cyclists of all ages enjoy a sunny morning on Latin America's largest bike-path network.

The TransMilenio, as the modern bus network is called, moves 750,000 passengers per weekday-almost 100,000 more than Washington D.C.'s subway system. And Bogotá's citizens are proud of their transportation, proud of their city.

That wasn't always the case. In 1988, during Colombia's first mayoral elections, a local radio station launched its own "virtual" candidate. The candidate's transport platform was simple: instead of fixing all the roads, why not remove the pavement remaining to level out potholes. Vehicles would then no longer have to "sink" into potholes-instead they would simply ride over the unpaved street.
