Zusammenfassung:The invention provides a highway real-time flow monitoring method and system based on ETC portal data, and the method comprises the steps: obtaining a target monitoring section set, and obtaining a traffic jam evaluation feature cluster corresponding to each target monitoring section in the target monitoring section set; and based on the monitoring section monitoring algorithm, analyzing the dispersion position of the traffic congestion assessment feature in the target feature cluster of the corresponding congestion assessment layer, and determining algorithm assessment information corresponding to the target monitoring section through the dispersion position information of each monitoring section monitoring algorithm. According to the method, the dispersion positions of the traffic congestion assessment features are analyzed based on the congestion assessment level, and the algorithm assessment information corresponding to the monitoring section is obtained by combining the dispersion position information of
