Patent ID: 8405521

Claim:
A statistic traffic information generating apparatus, comprising: a statistic traffic data storage unit that stores statistic traffic data associated with road links; a missing link extraction unit that extracts a missing link whose statistic traffic data is partially missing from the statistic traffic data storage unit; a complement rule storage unit that stores complement rules associated with an extraction of a complementary road link to be used to complement a missing part of the statistic traffic data of the missing link; a candidate link extraction unit that extracts candidate links to be candidates of the complementary road link extracted by the extraction unit, according to the complement rules stored in the complement rule storage unit; a calculation unit that calculates a degree of similarity between the statistic traffic data of the missing link extracted by the missing link extraction unit and the statistic data of the candidate links extracted by the candidate link extraction unit, for the respective complement rules stored in the complement rule storage unit; a priority order assignment unit that assigns a priority order to the complement rules stored in the complement rule storage unit, according to the degree of similarity calculated by the calculation unit; a complementary link extraction unit that extracts the complementary link for complement of the missing statistic traffic data, using a complement rule based on the priority order assigned by the priority order assignment unit; and a complement unit that complements the missing part of the statistic traffic data in the statistic traffic data of the missing link extracted by the missing link extraction unit, using the statistic traffic data of the complementary link extracted by the complementary link extraction unit.
