Alibaba Cloud, the cloud-computing unit of Alibaba, rolled out today version 2.0 of its urban traffic-management system City Brain in its home city Hangzhou at The Computing Conference, which welcomed 120k visitors this year. Started as a service to solve suffocating traffic, the company expects the program to tackle more problems for modern cities.

First launched in September 2016, City Brain is mainly used to improve traffic flows, make live traffic predictions, and detect traffic incidents using data from video footage, traffic bureaus, and public transportation systems. After two years, Hangzhou, the first city to embrace the system, dropped from the 5th to the 57th spot on the list for China’s most congested cities, according to the company.

The latest version is expected to monitor and control the city’s traffic at a larger scale and with more accuracy. Hangzhou City Brain 2.0 now covers a core area of 42 square kilometers in downtown Hangzhou, while the traffic violations are reported with 95% accuracy. The system has over 110 autonomous alert capabilities and 1300 traffic signals that are controlled by AI, according to Jing Zhi, deputy chief of the Zhejiang Provincial Public Security Department. Over 200 traffic policemen are available through the platform to attend to traffic emergencies.
