In China, traffic has reached epic proportions. All of those cars not only clog the streets, but contribute to the poor air quality. Emissions from such a large number of vehicles has created an environmental crisis, in addition to the congestion on the roads. An idea that has been considered for quite some time may finally be coming into reality
The Transit Explore Bus is being hailed as a solution to reducing smog as well as clearing traffic. It rides above major highways, along tracks affixed to the side of existing roads. It can carry close to 1400 commuters and cars that are less than 6 feet 6 inches high can fit under it. It's electric so it's better for the environment and since it fits over roadways, it's more earth friendly than digging tunnels for subways. It will also cost less and take less time to build.
