An overview of the origin and development of the "urban brain" construction
First, the origin of the "urban brain" construction
In October 2016, Hangzhou released the world's first urban brain program. In the city of Hangzhou, an artificial intelligence hub, the Hangzhou City Data Brain, will be installed. The city's brain will be used to solve problems such as traffic congestion in Hangzhou. The goal is to let the data help the city to think and make decisions, and to make Hangzhou a self-regulating and benign city.
The urban brain uses Alibaba Cloud's ET artificial intelligence technology to perform global real-time analysis of the entire city, automatically deploying public resources, and correcting bugs in urban operations. Traffic accidents and human flow trajectories are key issues that need to be solved in traffic scenarios. The members of the urban brain project team use artificial intelligence techniques such as deep learning and image recognition to perform single-point attack. For example, through data modeling and comparison of object movement trends in video, a significant error can be determined as a traffic accident, and the relevant road segments are Quick response to traffic light settings, route recommendations, etc.
