An operation section 32 calculates a guide route from the map database on the basis of navigation information, and determines whether a point having the reverse-run risk is included in the guide route referring to the reverse-run risk point information. Then, the operation section 32 discriminates the necessity of reverse-run risk measures on the basis of the determination result, and creates reverse-run risk correspondence information on the basis of the discrimination result.</p> |
