Hong Kong (CNN Business)Traffic used to be a frequent headache for residents in Hangzhou, the eastern Chinese city that’s home to Alibaba.
The metropolis of 7 million people once ranked fifth among China’s most congested cities, but it has now dropped to 57th on the list.
Alibaba (BABA) says that’s because of one of its inventions, dubbed the City Brain, which uses artificial intelligence to gather information across Hangzhou, such as video from intersection cameras and GPS data on the locations of cars and buses.
