Abstract
A vehicle travel-route guidance apparatus. The apparatus includes a map-storing device having internal intersection information that is furnished for executing a right-hand turn or a left-hand turn to bypass an intersection. The guidance apparatus further includes a device that determines whether searched links or nodes have internal intersection information associated therewith, either during, or after, link/node cost evaluation during a destination route search by the control unit. The guidance apparatus also includes a device for relatively changing an evaluation value of the link/node to preferentially include the link/node in a destination route when the control unit searches for a destination route by evaluation-value calculation, thereby ensuring that the most desirable destination route is chosen.
