New York City's congestion pricing picks up speed

By some measures, New York City's traffic is more congested than it's ever been. Enter: Congestion pricing. Since last Sunday, during most hours, cars crossing into the lower half of Manhattan are charged nine dollars. There's a higher toll for trucks. 

Fourteen hundred cameras keep tabs on the roughly 150,000 commuters entering the zone by car.

"If we can just impact on a proportion of those people, we can make a difference and make it a much better place for everybody," said Janno Lieber, who heads the Metropolitan Transportation Authority, which runs New York's sprawling subway, bus and commuter rail systems. "We're wasting a ton of money, literally billions of dollars, according to our business leaders, having people stuck in traffic."
