Three years ago Streetfilms brought you a comprehensive look at Bogotá, Colombia's TransMilenio, the world's most advanced Bus Rapid Transit system. TransMilenio changed the way Bogotá residents think about public transportation, becoming indispensable to the 1.7 million people who use the system daily. If anything, the bus network became a victim of its own success, handling more passengers and crowding than its planners anticipated. Today, ten years after TransMilenio launched, we revisit this groundbreaking transit system and examine how it must improve as it matures.

Since 1998, Bogotá, Colombia has built more than 300 kilometers of protected bikeways. Streetfilms recently had the chance to explore the city's bike network with the man responsible for building it, former mayor Enrique Peñalosa.

Anyone who claims that bike-sharing is a European-style transportation innovation has clearly never set foot in Hangzhou, China. The 50,000-bike system in this southern China city of almost 7 million people (about 1.5 million people fewer than New York City) blows all other bike-shares off the map. As Bradley Schroeder of the Institute for Transportation and Development Policy said, "I don't think there is anywhere you can stand in Hangzhou for more than a minute or two where you wouldn't have a Hangzhou Public Bike go past you."

You might be shocked at how much traffic consists of drivers who have already arrived at their destination but find themselves cruising the streets, searching for an open parking spot. In some city neighborhoods, cruising makes up as much as 40 percent of all traffic. All this unnecessary traffic slows down buses, endangers cyclists and pedestrians, delays other motorists, and produces harmful emissions. The key to eliminating it is to get the price of parking right.

Guangzhou is one of the fastest growing cities in the world. The economic hub of China's southern coast, it has undergone three decades of rapid modernization, and until recently the city’s streets were on a trajectory to get completely overrun by traffic congestion and pollution. But Guangzhou has started to change course. Last year the city made major strides to cut carbon emissions and reclaim space for people, launching new bus rapid transit and public bike sharing systems.

In this week's episode of "Moving Beyond the Automobile," Streetfilms takes you on a guided tour of past, present and future highway removal projects with John Norquist of the Congress for the New Urbanism.

Bus Rapid Transit (BRT) provides faster and more efficient service than an ordinary bus system. While a proper BRT route operates like a surface subway, the cost is much lower. In the latest installment of "Moving Beyond the Automobile," Streetfilms explains the key features of bus rapid transit around the world and how BRT helps shift people out of cars and taxis and onto buses.
