The invention relates to the technical field of traffic data processing, in particular to a holographic traffic state data set construction method based on multi-source information fusion, which comprises the following steps: acquiring an original data set, constructing a directed road network diagram and an undirected road network diagram according to a road network topological relation, performing imaging processing on traffic information by the road network diagram according to a color matching equation, and constructing a holographic traffic state data set. The method comprises the following steps: constructing an adjacent-order matrix, carrying out preliminary correction and completion on original traffic characteristic data through a space-time information compensation network in combination with a traffic information graph, establishing an iterative completion generative adversarial network (IGANI) model, generating a completion data set, constructing a weighted directed graph based on a road physical connection relation model established by the adjacent-order matrix and a directed road network graph, and carrying out data processing on the weighted directed graph. And predicting traffic state data in a period through a GE-LSTM traffic state prediction model to generate a prediction data set, and constructing a holographic traffic state data set, thereby effectively overcoming the problem of data missing caused by equipment damage and aging faults, and effectively improving the control effect of a traffic control system.
