- the route of the moving object is displayed on the left side of the screen.
- the moving object may be switched to a deformed diagram showing the details of the intersection.
- the case where “no name” is displayed when the name of the intersection is not added to the additional information of the node is described.
- the temporary information of the intersection is obtained from the information related to the intersection.
- a name may be generated and the temporary name may be displayed.

- Embodiment 5 This has the effect of making it easier to identify the intersection.
- Embodiments 1 to 4 above do not specifically refer to the reception of VICS information.However, if VICS information transmitted from an intersection, etc. can be received, the VICS information is moved from that information. Congestion information on the body route may be extracted, and if there is a congested point, the point may be blinked on a map and the intersection of the congested point may be highlighted. For example, if traffic congestion occurs between the intersection of “City Hall” and the intersection of “Akasaka”, the names of “City Hall” and “Akasaka” intersection, etc. By blinking or displaying a congestion mark, the intersection of the congested place is clarified.
