The autonomous driving bus route in Yuhang District is the first one of its kind powered by vehicle-road coordination technology in Hangzhou, East China's Zhejiang province. This 5-kilometer bus line winds through schools, industrial parks, residential compounds and subway stations, free of charge for all citizens.

Autonomous driving buses achieve holographic sensing of the road network through smart sensing devices such as high-definition cameras and radars along the roads. The vehicle-road coordination technology also effectively improves operational safety for the vehicles.

That said, each of these buses still has a human supervisor, who would immediately take over the vehicle in case of emergency to further ensure passenger safety.
