PROBLEM TO BE SOLVED: To provide a route guiding wherein, regardless of travel control, a destination is reached with sure with no wasteful running. SOLUTION: A controller 5, in response to signals from a GPS receiver 1, an azimuth sensor 2, a wheel speed sensor, a storage device 4, and an operation part 6, let a display device 7 display a road map about current travel region of a car, and allows a calculation process for displaying car's current position on the map road. Here the control device 5, if a destination route crosses a divider strip when the destination route is explored, sets a cost of a node positioned on out-going side of a link which is such entrance direction as a right turn is allowed for a destination in keep-to-the-right to be infinite. |
