Checkout China's Floating Buses

To combat the massive traffic jam in China’s big cities, Beijing firm has showcased  a concept bus that drives over the traffic.

The raised bus is wide enough to cover two traffic lanes, and would travel along tracks on either side of the road so that cars up to 2 meters (6.6 ft) tall can pass underneath. Ramps would fold outwards to give users access to the street when the bus reaches a stop (though in the company's animation these do look rather steep and treacherous). It can also travel at speeds of up to 60 km/h (37.2 mph) and is equipped to carry up to 1,400 passengers.

The system is expected to eplace up to 40 conventional buses, a move it says would save 800 tons of fuel and 2,480 tons of carbon emissions each year. It will save a lot of road space and perform the same role as a subway, albeit at 16 percent of the cost. It would also be much quicker to manufacture and construct, said Chief Engineer, Song Youzhou .

In 2010, Song presented this futuristic transport solution, which had been designed with Shenzhen Huashi Future Parking Equipment Co. Ltd (www.hsfuture.com). The company had planned to build a test track in the same year, but was not successful. This time around, Song will be working against not just the technical hurdles inherent in such an ambitious project, but a culture that is trending towards personal car ownership.

However, he says some Chinese cities have already shown interest in the Elevated Transit Bus and that a full-scale version is being built in Changzou, with testing to commence in July or August.
