Abstract
A navigation device provides a driver with proper instructions to which direction to drive when he approaches a junction at which an entering road branches out into two or more outgoing roads. Such instructions are generated not only based on a physical structure of the junction and road names but also based on a customary way of driving. When the entering road name is the same as the outgoing road name toward destination, a driver customarily keeps a through-traffic lane. If the outgoing road toward his destination branches out to a side opposite to the through-traffic lane, he would drive onto a wrong road. Under such situation, the navigation device according to the present invention gives a driver clear instructions to which direction he should drive.
