Fecha de publicación: 15/08/2023 Fuente: Wipo "BigData" The invention discloses a traffic flow control system and method based on big data, and relates to the technical field of big data application, and the system comprises a main control module, a road condition collection module, a central processing module, a prediction analysis module, a traffic control module, a log recording module, a road condition query module, a path selection module and a navigation module. According to the traffic flow control system and method based on the big data, the central processing module carries out centralized processing on the system instruction sent by the main control module and the user instruction sent by the road condition query module; multiple feedbacks are constructed between the prediction analysis module and the path selection module, between the prediction analysis module and the log recording module, and between the log recording module and the path selection module, so that real-time information interaction between the user and the control system is realized, and hysteresis of traffic prediction information is avoided; in addition, the predictive analysis module not only can receive information of the central processing module, but also can receive feedback information of the log recording module and the path selection module.
