An object is to make it possible to learn a prediction model for precisely predicting the number of passersby at a prediction time point. A learning unit 300 learns parameters of the prediction model with respect to each of a plurality of observation points based on learning data such that the number of passersby at the observation point at a prediction time point predicted using the prediction model matches the number of passersby at a time point corresponding to the prediction time point included in the learning data. The learning data includes, with respect to each observation point, a past time point of the observation point and the number of passersby at the observation point at the past time point. The prediction model has parameters including a first weight indicating the influence of the numbers of passersby at other observation points based on distances to the other observation points, a second weight indicating the influence of the numbers of passersby at the other observation points based on a travel route, and a third weight differing from the first weight and the second weight and indicating the influence of the numbers of passersby at the other observation points.
