Expressway asset data visualization method and system based on digital twinning

The invention provides an expressway asset data visualization method and system based on digital twinborn, and the method comprises the steps: managing expressway asset data, combining target expressway asset data with comparison asset data in different states and expressway asset digital twinborn bodies needing to be estimated, obtaining a visual management data set, and carrying out the prediction of the expressway asset digital twinborn bodies through the visual management data set. According to the method, target comparison asset data with the same asset state as the target expressway asset data is determined through state association information among data items in a visual management data set, and a visual display material corresponding to the target comparison asset data is the visual display material of the target expressway asset data. According to the method, the asset data management is converted into data content identification, the reference asset data with the same asset state as the target expr
