china has a Futuristic ‘straddling bus’ to let cars drive underneath
China has unveiled design concept for a “straddling bus” which lets cars drive underneath, saving not only the road space but also help reduce air pollution, state media reported on Wednesday. Also known as a land airbus, the concept was the brainchild of Beijing-based Transit Explore Bus, which took their design to the just-concluded high-tech expo in the city. The passenger compartment spans two traffic lanes and sits high above the road surface on a pair of stilts, leaving the road clear for ordinary cars to pass underneath, Xinhua reported.
Regardless of whether the bus is moving or not, cars under two meters high can easily pass through. Running along special tracks, the bus can carry up to 1,400 passengers and travel at a top speed of 60 kilometers per hour. “The biggest advantage is that the bus will save lots of road space,” said chief engineer of the straddling bus project Song Youzhou. He said the bus has the similar function of the subway, but its cost is only 16 per cent of the subway. The manufacturing and construction lead-time is also much shorter. Powered by electricity, the straddling bus could replace about 40 conventional buses, potentially saving more than 800 tonnes of fuel annually and reducing 2,480 tonnes of carbon emissions, Song said.
