The future of public transport has already hit the road in Beijing thanks to the first successful test of the TEB or Transit Elevated Bus: the first electric bus that promises to reduce traffic and smog. It certainly takes you aback when you see it circulate: it is two meters high, has a large passenger compartment 7 and a half meters wide and 21 meters long and can take up to 300 passengers. It straddles the roadside from on high, allowing car traffic to pass under it. According to the engineers who designed it, the TEB does the job of 40 conventional buses and helps smooth the traffic flow in that it does not take up road space. It travels the same route like an elevated metro, though costing less than a fifth of a traditional metro. Perhaps it will finally do away with the classic phrase: "If you come to Beijing, try not to breathe".
