Products and Applications
  • City Brain “Tianji”

    The Tianji city brain is a traffic flow forecasting system. It predicts future vehicle and pedestrian traffic flow through the continuous analysis of historical and real-time video data. It provides reference data for decision-making on traffic management and control to avoid congestion, pedestrian injuries, and other issues. Currently, the system can predict next one-hour period vehicle and pedestrian traffic flow with an accuracy rate over 90%.

  • City Brain “Tianjing”

    Tianjing is a municipal construction and management system. It provides warning services for automatic surveillance of municipal affairs, while aids various governmental organizations in urban management, security supervision, fire protection, housing construction, and policy bureau. It also assists with manual inspections, eliminates hidden risks in municipal engineering, and improves intelligent municipal administration.

  • City Brain “Tianying”

    Tianying is a progressive video search engine. It quickly locates specific objects based on real-time searches of global video resources. For example, it only takes 1-2 seconds for Tianying to process search results and find missing persons or track hit-and-run suspects. Its accuracy rate for pedestrian recognition is over 96%.

  • City Brain “Tianyao”

    Tianyao is a smart full-time global traffic patrol alarm system which provides comprehensive real-time perception of traffic accidents and automatically determines the specific cause of incidents, such as people-, vehicle-, object-, or event-based issues. It automatically identifies traffic accidents and violations, pushes notification to the command center for processing within 20 seconds with over 95% recognition accuracy rate. Tianyao performs 24/7 uninterrupted analysis of urban traffic to reduce security risks, lower the workload of traffic police, and improve the efficiency of law enforcement by freeing up manpower from manual monitoring.

  • City Brain “Tianqing”

    Tianqing is a large-scale visual computing platform,which consists of three components: a video access system, a real-time/offline computing system, and a visual search system, providing a comprehensive large-scale visual computing solution. It has the capacity of rapid and flexible cloud deployment, which is an innovative security product. It provides customers with on-demand smart analysis capabilities, which achieves accelerated video analysis speeds of up to 1000x and only takes one minute to process 16 hours of video.

  • City Solutions

    Hangzhou:
    City Brain systems achieved over 92% accuracy rate for video inspection and recognition, while automatic traffic control and management raises 15% faster of transportation by using Internet traffic lights. Finally, efficient roadway access for special vehicles (ambulances, fire engines, etc.) increased by 50%.

    Suzhou:
    City Brain systems optimized public transportation through comprehensive data analysis. The passenger flow and volume management for two pilot bus lines increased by 17% and 10% respectively, a marked increase in efficiency.

    Shanghai:
    City Brain systems performed digital processing and analysis on urban infrastructure, including transportation, energy, water supply and construction, also smart decision-making for public security, public transportation, and public services authorities.

    Xiongan New Area:
    The City Brain Lab cooperated with Xiongan New Area to build the future smart city consisted of cloud computing-based infrastructure, Internet of Things-based urban neural network and City Brain-based artificial intelligence hub.

    Quzhou and Jiaxing:
    Since the one month period from launch of “Tianying: progressive video search engine”, 15 cases of theft and 4 lost persons cases have been solved, as well as exposing nearly 10,000 incidents of uncivilized behavior in public.
