    It is 40 meters long and 6 meters wide. This must be the biggest bus you have ever seen. It can carry 1,200 to 1,400 people.

It is China’s new Super Bus. It is going for a test run in Beijing at the end of this year. Some other cities are also interested in running the Super Bus. They hope the traffic problems will be solved.

The Super Bus runs along fixed tracks (固定轨道) . The bus sits on top of two 2.2-meter-tall legs. The legs have wheels at one end. Small cars can drive under the bus, so the Super Bus does not take up road space.

The bus runs on electricity and solar power. It can travel up to 60 km every hour. Its creator, Song Youzhou, says a lot of traffic jams will be reduced.

The Super Bus can do the work of 40 buses. In that way, it can save 860 tons of fuel (燃料) every year, according to Song.

“To build a Super Bus and its track costs less than building subways. Subways are nearly ten times more expensive to build.” Song said.

Some people worry that the Super Bus may not be safe. However, Song says there’s no need to worry about. The Super Bus has laser scanners (激光扫描仪) between its legs. The scanners make sure the cars keep a safe distance(距离).
