Track information generating device, track information generating method, and computer-readable storage medium

A track information generating device (10) comprises a self-contained navigation track acquisition unit (21a) adapted to acquire a self-contained navigation track, a matching track acquisition unit (21b) adapted to acquire a matching track, and to acquire a degree of reliability of the matching track, a GPS track acquisition unit (21c) adapted to acquire a GPS track, and a self-contained navigation information correcting unit (21d) adapted to acquire a degree of reliability of the GPS track and to set one of the GPS track and the matching track, having a higher degree of reliability, as a correction target track to correct the self-contained navigation information so as to reduce a difference between the self-contained navigation track and the correction target track.
