Alibaba Cloud and the Hangzhou city government announced the launch of ET City Brain 2.0, a cloud-powered and AI-driven urban traffic-management system that aims to increase the city’s efficiency.
After over two years of testing in Alibaba’s home base, ET City Brain has become the new infrastructure (基础设施) for Hangzhou, with a total coverage of 420 square kilometers in area, including over 1,300 traffic lights. Over 200 traffic officers are connected via mobile phones, enabling them to receive real-time alerts on any traffic-related emergencies.
In version 2.0, the system will optimize the city’s firefighting abilities by providing key information to firefighters, such as water pressure, the number and position of fire hydrants (消防栓) in a given area, the location of gas pipes and other details they need to know. The information is instant, making the entire firefighting process faster, safer and more accurate.
City Brain gives meaning to data. By using AI and advanced algorithms (计算程序), City Brain is able to analyze a large amount of data and turn them into useful information in real-time speed.
As a result of City Brain’s ability to predict traffic flow, detect accidents and provide instant feedback, Hangzhou has dropped from 5th to the 57th on the list of China’s most congested cities. Hangzhou is probably the only city that can tell you how many cars are on the street at any given time.
In the case of medical emergencies, City Brain is able to change traffic lights, so emergency vehicles like ambulances and fire trucks can head to the scene without interruption, accelerating their arrival time by 49%.
Dr. Wang Jian, head of Alibaba’s Technology Steering Committee who invented the term “City Brain”,said the system is designed to empower a city to act quickly and directly. It is more than just about traffic management. It’s really about how to make city more livable at a time of shrinking natural resources around the globe. “It is a matter of sustainability, while using as little natural resources as possible,” Wang said, “This is just the beginning.”
