Traffic jams are a big problem in China. This Super Bus may be the answer .The bus is very large. It is 40 meters long and 6 meters wide. It is like a very long classroom. It can hold 1,200 to 1,400 people.It has two 2.2-meter-tall legs. The legs have wheels at one end. Small cars can drive under the bus , so it does not take up road space . The Super Bus is going for a test run in Beijing at the end of this year.
