In probe data tallying, tallying with a high-resolution spatial granularity is enabled, and high-precision tallying is enabled by suppressing loss of the information quantity of the probe data. A data recording part records probe data generated by a vehicle, which is a probe. A filter coefficient recording part associates filter coefficients determined depending on distances between a road, which is a geographic element existing in a geographic range segmented into a plurality of regions, and the plurality of regions, with the plurality of regions, respectively, and records the filter coefficients. A filter computation processing part selects regions corresponding to the probe data recorded by the data recording part, respectively, from among the plurality of regions, reads the filter coefficients associated with the selected regions and recorded by the filter coefficient recording part, respectively, weights the probe data with the filter coefficients, respectively, and tallies the probe data.
