Vehicles can pass underneath the bus whether it is moving or stationary and it is powered purely by electricity. Li Nan, a spokesperson for the company behind the TEB, said the test track will be kept for at least one year to collect data on experiments. The company also plans to open the road for vehicles to pass under the TEB in 2017. [Photo/China News Service]
