The invention discloses an algorithm model for complementing traffic data acquisition missing of a traffic operation system. The algorithm model comprises the following steps: determining a traffic data missing road section and a traffic data missing time period; acquiring traffic data of a traffic data missing road section and nearby road sections; extracting spatial correlation; and complementing the missing traffic data of the missing road section according to the spatial correlation. According to the method, the spatial correlation characteristics between the traffic data of the current road section and the traffic data of the nearby road sections are extracted through the deep learning model, the traffic data are complemented according to the spatial correlation characteristics, and the method has the advantages that long-time missing of the traffic data can be complemented, and the complementing effect is good.
