Here in America, many cities have begun embracing bus rapid transit systems as fast, cost-effective alternatives to subways. In China, meanwhile, engineers are taking a very different approach to modern bus transit. It’s called the Transit Elevated Bus (TEB), and it debuted earlier this month at the 19th China Beijing International High-Tech Expo.

As its name suggests, the TEB’s passenger rides above traffic, rather than alongside of it. Its massive frame straddles cars, allowing them to pass underneath it without disrupting the flow of traffic. With its sleek lines and unusual form factor, the TEB looks distinctly futuristic.

Civil engineers in China hope that the TEB could allow them to bring the convenience of a subway system to cities at a fraction of the cost. Because it can carry hundreds of passengers and doesn’t require devoted lanes, TEB has the potential to be even more cost-effective than bus rapid transit systems.

“With a carrying capacity of 1,200 people at a time, the TEB has the same functions as the subway while its cost of construction is less than one fifth of the subway. Its construction can be finished in one year,” said Bai Zhiming, chief engineer of the TEB project.

Of course there are still some significant practical hurdles to overcome before the TEB hits the streets. First and foremost, drivers will likely need some time to acclimate to the idea of driving underneath enormous, highway-straddling buses. This will mean city planners will have to be careful about where they choose to implement the first TEB systems.

The engineers behind the TEB project hope to begin trial operations in Qinhaungdao City in the second half of 2016. You can check out a demonstration of the TEB in the video below!
