<p>An information processing device according to the present invention is provided with: a traffic data estimation unit which estimates, from probe data collected from vehicles traveling along links, time-series data for the link transit time of each link, where the term "link" refers to a road segment and the term "link transit time" refers to the time required to transit a link; and a traffic data interpolation unit which calculates the correlation coefficients between the link transit time of a link to be interpolated, the time-series data for which has missing data, and the link transit times of a plurality of links to be applied, the time-series data for which does not have any missing data and is used for interpolation, and then calculates interpolation data for interpolating data at missing time points in the time-series data for the link transit time of the link to be interpolated, on the basis of the calculated correlation coefficients and the link transit times of the plurality of links to be applied. This makes it possible to accurately interpolate data for links in an area, regardless of the proportion of links for which all data is not available.</p> |
