Discovery News describes it as “a huge bus that operates like a train on wheels,” and is tall enough so vehicles lower than 2 m can go through under. According to China Hush, the bus can speed up to 60 km/h carrying 1200-1400 passengers at a time. It costs about 500 million yuan to build the bus and a 40-km-long path for it, about 10% of building equivalent subway. It is said that the bus can reduce traffic jams by 20-30%.
Environmentally, each bus can save up to 860 tons of fuel per year, reducing 2,640 tons of carbon emissions. It is powered partly by solar panels on each bus, but it’s powered mostly by electricity. Beijing’s Mentougou District reportedly will launch a pilot program in the near future.(http://www.investmentpostcards.com/2010/08/09/china-boosts-transportation-infrastructure/)
