PURPOSE:To enable a driver to confirm a correct proceeding direction at an intersection by informing the proceeding direction of a vehicle at each intersection along with the shape of the intersection based on inputted intersection data. CONSTITUTION:This system is provided with a digitizer (a route data input means and an intersection data input means) 3 for inputting route data and intersection data, an IC card (a data storage means) 9 storing data and a main body part informing the proceeding direction of the vehicle at each intersection and the shape of the intersection based on each piece of data. Then, before driving, route data and intersection data are inputted to the IC card 9 through the use of the digitizer 3 and the IC card 9 is mounted on the on-vehicle main body part so that the main body part informs both the proceeding direction at each intersection and the shape of the intersection through a display part. |
