Resumen de I don't brake for Bogotá.
Traffic in Colombia's capital city of Bogot´ consists of more than a million cars, trucks and buses, but the city's packed highways still keep more cars cruising than other major cities do, say physicists Jose Daniel Munoz and Luis Eduardo Olmos of the National University of Colombia. They videotaped a car as It drove and then constructed rules for acceleration and braking in a cellular automaton traffic model, in which cars are points on a grid responding to neighboring points. According to the model, the key is aggressive driving getting nearly bumper-to-bumper before slowing down. The toll for that higher flow: car accidents cause at least one in six violent deaths in Colombia, the researchers say in a paper submitted to the International Journal of Modern Physics C.
