A QoE-based traffic dispatching big data system and method, including an infrared sensor, an intersection camera terminal device, a data transmission network, a big data processing core platform, a traffic control center, and a traffic signal terminal. Collect data through infrared sensors and intersection camera terminal equipment, and then transmit the data to the big data processing core platform through the data transmission network. The background will give an optimized solution, and then the traffic control center will execute the plan to realize the real-time traffic signal terminal. scheduling. The present invention is a QoE-based traffic dispatching big data system and method. Through real-time monitoring of traffic data in various areas of the city, and analysis, processing and data mining by the big data processing core platform, comprehensive consideration is given to different areas, different road sections, different time periods, and different The data of motor vehicles, pedestrians, etc., calculate and optimize the dispatching plan, through the time-varying control of traffic signals, regional coordination, three-dimensional dispatching, intelligent recommendation, etc., improve road traffic rate and regional coordination ability, reduce congestion, improve regional dispatching quality and experience quality.
