Rapid transit is a very useful method to reduce car use in big city. It cuts greenhouse gas and polutant emmision. It reverses oil.It has very high capacity up to 10,000 people per hour in a fixed direction and it uses less space than wide road.

Shanghai Subway[edit]

It's an amazingly spanding system in an amazing city. It will reach over 250 km in the end of 2007 and will reach 400 in 2010. At that time, it will be the biggest transit system in the world.
