Alibaba says its AI-driven “City Brain” project in Hangzhou has improved traffic.

Chinese giant online company want to resolve traffic problem using artificial intelligence.

Residents in Hangzhou, the eastern Chinese city and a home to Alibaba, regularly face problems with traffic.

The city has been previously ranking fifth among Chinese congest cities. But now it drop down to 57th.

Alibaba representatives say that’s because of one of its inventions, called the City Brain. It uses artificial intelligence to gather information across Hangzhou, such as video from intersection cameras and GPS data on the locations of cars and buses.

The platform analyzes the information in real time. It coordinates more than 1,000 road signals around the city with the aim of preventing or easing gridlock.

The system was testing for two years. It appears to be working.

“The cities in China probably are facing more challenges than any other city,” said Wang Jian, chairman of Alibaba’s technology steering committee.

Some regular drivers confirm things have improved. However, most people are worried about the impact of artificial intelligence on their privacy.

“We have to solve the privacy issue,” Wang said. “That’s for sure.”

But he argued that the benefits of projects like the City Brain will outweigh concerns in the end.
