A model of a Transit Elevated Bus (TEB) debuted at the 19th China Beijing International High-Tech Expo, which concluded on Sunday. The TEB is a purely homegrown invention of China, with its passenger compartment sitting above other vehicles on the road below, allowing cars to pass underneath. The TEB is designed to increase the utilization of road space.
Trial operations of such a bus will start in Qinhuangdao City, north China’s Hebei Province, in the second half of 2016.
