Beijing and other large Chinese cities top lists of the world’s most congested and polluted metropolitan areas. Chinese developers say the Transit Explore Bus could be part of a solution to both problems. The elevated bus, which is set to be tested this year, travels above the fray at a speed of about 40 m.p.h. (64 km/h), cruising over cars stuck in traffic and allowing traffic to pass below when it pauses at stations. And because it’s electric, it wouldn’t contribute to the smog that chokes so many Chinese cities.
