Technicians debug a self-driving bus in Shenzhen, south China's Guangdong Province, Nov. 30, 2017. Four self-driving buses began trial operations Saturday in south China's Shenzhen, a city known for its high concentration of hi-tech companies. The smart buses, which are smaller than an ordinary bus, began running on a 1.2-kilometer route with three stops in the bonded zone of Futian. The buses have a designed speed of 10 to 30 kph. Equipped with lidar censors, cameras, and GPS antenna, the buses can avoid hitting pedestrians, vehicles and barriers, safely change lanes and stop at designated sites. (Xinhua/Mao Siqian)
