A statistic DB creation processing section 102 creates a statistic traffic DB 160, based on past actual traffic data (probe DB or VICS DB), and stores it in a statistic DB storage section 160. A reference-link-candidate extraction processing section 106 extracts a complement target link (temporal missing link) from the statistic traffic DB 160, and further extracts complementary-reference-link-candidates for the complement target link, according to plural extraction rules to extract complementary-reference-link-candidates. A complement-evaluation application processing section 108 calculates correlation coefficients of the statistic traffic data of the complementary-reference-link-candidates to the statistic traffic data of the complement target link for the respective extraction rules, assigns a priority order to the extraction rules in the order of higher correlation coefficient, and complements the missing data of the statistic traffic data of the complement target link by the use of the statistic traffic data of the complementary reference link extracted by the extraction rule of the highest priority.
