An anonymous reader writes: A Beijing company has unveiled spectacularly futuristic designs for a pollution-busting, elevated bus capable of gliding over the nightmarish mega-jams for which urban China has become notorious. The "straddling bus," which owes more to Blade Runner than China's car-clogged highways, is supported by two legs that run along rails laid along the roadside. Those legs allow the Transit Explore Bus, or TEB's giant frame to glide high above the gridlock at speeds of up to 60km per hour. Equally, vehicles that are less than two metres high will be able to drive freely underneath the bus, even when it is stationary. "The biggest advantage is that the bus will save lots of road space," Song Youzhou, the project's chief engineer, told Xinhua, China's official news agency. Song claimed his buses, capable of transporting up to 1,400 commuters, could be produced for 20% of the price of an underground train and rolled out far more quickly since the supporting infrastructure was relatively simple. One TEB could replace 40 conventional buses, he said.You can watch the concept video here. Interestingly a very similar -- if not the exact same -- concept has come out of China before. Not sure what kind of developments have been made in the six years since then.
