Finding lessons in how green transit can survive and thrive in an unlikely place.
Tehran is not an obvious place for sustainable transportation ideas to thrive. Gas used to cost next to nothing—about 38 cents per gallon—until December, when the government quadrupled the price to about $1.50 per gallon for a monthly ration of about 16 gallons per car, and closer to $3.00 for any amount past that. With gas so cheap, it's no wonder people choose to drive rather than take the train or the bus. In Tehran, in 2008, just over a quarter of all trips were in private and shared taxis, and another 27 percent were in private cars, according to data from the city. Tehran has been designed for cars, too: freeways slice through the city, cutting off neighborhoods from each other.
