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."

Over the last four years, New York City has seen a transportation renaissance on its streets, striking a better balance by providing more space for walking, biking, and transit.

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.

What's a road diet? Quite simply, traffic-calming expert Dan Burden told Streetfilms, "A road diet is anytime you take any lane out of a road."

What's the most effective way to make city streets safer? As Chicago Alderman Mary Ann Smith told Streetfilms, "Signs don't do the job, even having police officers on the corner does not do the job." To prevent traffic injuries and deaths, you need to change how the street functions and make it feel slower for drivers. You need traffic calming.

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.
