Beijing, China -- home to over 20 million people... it's also home to some of the worst traffic jams on the planet. Earlier this week, thousands of cars and trucks where stuck for nine days in a 60-mile-long jam outside the city.

Chinese engineer Song Youzhow says he has come up with a concept that will put an end to Beijing's traffic misery ... the “Elevated High-Speed Bus.”

The bus can carry up to 1,400 passengers above the street while traffic passes underneath it. Sung says the bus costs a fraction of building a subway system and is environmentally friendly as well.

[Song Youzhou, Elevated High Speed Bus Inventor]:
"The 'Elevated High-Speed Bus' is a low-carbon, environmental-protection and high-efficiency project. It solves the problems of ordinary fuel-consuming buses, including air pollution, carbon emission, space occupying and low efficiency. The 'Elevated High-Speed Bus' combines the merits of BRT (Bus Rapid Transit) and subway."

The Bus has zero gas emissions and largely consumes electrical power which is supplemented by solar energy gathered from rooftop panels.

Using radar technology the bus will warn drivers passing underneath if they are too close to its wheels and also signal trucks to detour if they are too large to pass beneath it.

China plans to test the bus on a 200-mile-long road on the outskirts of Beijing in the near future.

Song is confident the test will be a success and that the elevated high-speed bus will prove to be a solution for congested cities all over the world.
