A navigation apparatus includes: a map information storage means 103 for storing road information; a position estimation means 111 for estimating the position of the vehicle; a map matching means 112 for specifying link candidate points corresponding to the position of the vehicle; a parallel roads determination means 121 for detecting links of parallel roads that extend mutually parallel to one another; a traveling link determination means 122 for, for each link of the parallel roads, determining whether it is a traveling link upon which the vehicle is traveling, or a parallel link that extends parallel to the traveling link; and a link position correction means 125 for obtaining position correction amounts for nodes of the traveling link and of the parallel link on the basis of the distance between the link candidate point that corresponds to the traveling link and the position of the vehicle. |
