| Besides traffic congestion, the system is now being used to warn about infrastructure damage and to predict bad weather. In July 2017, Hangzhou began to use the City Brain project, mainly based on big data, cloud computing and artificial intelligence, to handle urban governance issues and build a smart city. To date, Hangzhou's urban management administration authorities have collected nearly 4 billion pieces of information. A large number of local companies including Alibaba Group have provided technical support to the project. The operation of the City Brain in Hangzhou provides a specific scenario - not only including the usage of hardware but also the idea of its application. It will also provide new opportunities for the city's development in the digital economy, according to the working team that initiated the City Brain project. As the driver of the transformation led by digital methods, the City Brain project will make the concept of "connecting everything online" realized in every industry, thereby boosting economic growth and benefiting the people's livelihood, according to the team. |
