Chinese tech giant Baidu announced that its newly developed self-driving bus would begin mass production as the 100th bus came off the production line Wednesday in southeast China's Fujian Province. The self-driving bus, named Apolong, was co-developed by Baidu and commercial vehicle manufacturer King Long. The bus, which lacks a steering wheel, driver's seat and brake, is instead equipped with a Baidu Apollo autonomous driving system, which is able to perceive its surroundings, predict the movements of vehicles and pedestrians, and plan optimized routes based on high-definition maps and intelligent sensing capability, according to Chen Weixiang, vice CTO of King Long.
