ABSTRACT:
The navigation apparatus gives, to a map match processing portion, the measured present location and progress bearing of the vehicle with the use of the position bearing measuring portion for each predetermined period. The map match processing portion reads out the road data about the road close to the measured present position from the memory apparatus to effect the map match processing with respect to each link in accordance with the road data for correcting the measured present position. The correcting operation is effected only when the frequency, where the similarity degree with respect to the measured present position and progress bearing at this time is judged to be larger than the predetermined threshold value, is larger than the predetermined constant Ck. The road data are visually displayed on the visual displaying region of the displaying apparatus. The predetermined diagrams are displayed in a superimposed manner, in the corrected present position, on the road data visually displayed.
