Elevated Straddling Bus design to avoid the Traffic jams

Designs for an elevated bus that carries passengers over cars have been unveiled by engineers in China.

Traffic congestion is a condition on transport networks that occurs as use increases, and is characterized by slower speeds, longer trip times, and increased vehicular queueing. The most common example is the physical use of roads by vehicles. When traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream, this results in some congestion.

As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is colloquially known as a traffic jam or traffic snarl-up. Traffic congestion can lead to drivers becoming frustrated and engaging in road rage.

Models for the Transit Elevated Bus (TEB) show the vehicle – which resembles a tram more than a bus – moving above the road surface while cars drive through the tunnel-like space beneath it.

The designs were unveiled at the 19th China Beijing International High-Tech Expo alongside models of deep-sea submersibles, lunar rovers and virtual-reality canoes.

While the model debuted at the Beijing expo looks more like a toy railway set than an example of the future of city transport, plans for the elevated bus are already taking shape.

The TEB will have a capacity of 1,200 passengers, the same as a standard subway train, but will cost just one fifth as much to build.

"Its construction can be finished in one year," said Bai Zhiming, the engineer in charge of the TEB project.

Running on rails embedded into the road surface, the elevated bus is one possible solution to China's problems with traffic congestion.

  1. Wow! It is unbelievable. It is challenging for the traffic management companies to handle event traffic control with utmost perfection, and keep the vehicles on the roads moving at their own pace, without being trapped in jams.
