The autonomous driving shuttle demonstration line located in the Future Science and Technology City of Yuhang District, Hangzhou City, Zhejiang Province is the first bus route in Hangzhou that combines vehicles and roads for autonomous driving. The total length of the line is about 5 kilometers, passing through schools, industrial parks, residential areas, and subway stations. Citizens can experience it for free. It is understood that autonomous buses achieve holographic perception of the road network by deploying high-definition cameras, radars and other intelligent perception devices along the entire road section, and rely on vehicle road collaboration technology to achieve intelligent interconnection between vehicles and roads, effectively improving the safety of vehicle operation. In addition, each intelligent connected vehicle is equipped with a safety officer. In case of emergency, the safety officer will immediately take over the control of the vehicle to ensure the safety of passengers. (Lai Xin She)
