To provide a congestion predicting model generation device capable of improving accuracy in predicting a congestion and also suppressing an increase of an arithmetic amount to be required in constructing a congestion predicting model.SOLUTION: A congestion predicting model generation device includes: a population data acquisition section 111 for acquiring population data of multiple groups classified in response to positions and attributes of persons; a congestion data acquisition section 113 for acquiring congestion data indicating a congestion state corresponding to a position; and a congestion predicting model construction section 115 for performing regression analysis by defining population data for each group as an explanation variable and defining congestion data at a congestion predicting position for predicting a traffic congestion as an objective variable, so as to select population data of groups where a degree of contribution with respect to congestion data at a congestion predicting position is relatively higher among the multiple groups, and then constructing a congestion predicting model by regression analysis on the basis of selected population data and congestion data at a congestion predicting position.SELECTED DRAWING: Figure 1
