PURPOSE:To previously decide a direction to advance a car or a lane to travel the car at a guide point such as a crossing, etc., by displaying the lane to travel the car together with the next guide point shown by an abstract graphic when the car arrives in front of the guide point such as the crossing, etc. CONSTITUTION:A guide point information storing means (b) stores guide point information concerning the middle guide point such as the crossing, etc., in a set guide route corresponding to each middle guide point. Further, a current traveling position calculating means (c) calculates the current traveling position of the car and a next guide point specifying means (d) specifies the middle guide point to be next arrived by monitoring the current traveling position. A traveling lane judging means (e) judges the lane to travel the car at the next guide point based on the guide point information and a traveling lane display means (f) displays the lane to travel the car together with the next guide point shown by the abstract graphic before the current traveling position arrives at the position of the next guide point. Thus, since the direction to advance the car or the lane to travel the car, etc., are clearly displayed at the guide point such as the crossing, etc., the burden of a driver is reduced. |
