Abstract
A navigation apparatus for guiding a vehicle to a destination, a data storing section stores an information set including at least location information for identifying a location of a travel burden point on a road network, link information indicating a road linked to the travel burden point, and a reference hesitation value indicating a degree of a driver's hesitation to go through the travel burden point, and a characteristic value of the driver. A point guidance data generating section generates point guidance data representing guidance for the travel burden point based on a current location derived by a location deriving section, a path obtained by a path obtaining section, and the information set and the driver characteristic value stored in the data storing section.
