Disclosed is a route guidance apparatus of a personal navigation terminal, which includes a road structure information storage unit for storing information related to road structures, a user preference information storage unit for storing at least one road structure preference representing a preference of a user for the road structures, and a controller for determining a current location of the personal navigation terminal, computing routes to a destination from the current location, and selecting a user-preferred route preferred by a user from among the routes based on the at least one road structure preference. In the route guidance apparatus, a personal navigation terminal displays routes based on user preferences reflecting user characteristics instead of simply displaying the shortest route, thereby causing a user to take a proper route according to one's own characteristics and degree of fatigue.
