The map data that has been edited is sent from the server 4 to the mobile terminal 2 and displayed (S11, S12).

For example, as shown in FIG. 9, a case where a route from the current location 20 to the destination 22 is searched will be described below.
21 and 23 are branch points of the road network 14b. Reference numerals 24a to 24d indicate inaccessible information indicating a time zone when the road is closed in the corresponding road section, and a shaded time zone indicates a closed time zone. For example, the impassability information 24a indicates that the section from the current location 20 to the branch point 21 is closed from 18:00 on the current day to 6:00 on the next day.
Therefore, according to the current time (current date and time 18), in the time zone where the current location 20 to the branch point 21 to the destination 22 or the current location 20 to the branch point 21 of this route cannot pass, the current location 20 to the branch point. 23 to the branch point 21 to the route from the destination 22 are adopted as route information.

In this embodiment, the road inaccessibility information 14ca is stored in advance in the storage unit 14 of the server 4 and is used for route search. Therefore, even if there is road construction, the route information that can be passed is acquired. This improves the reliability of route information guidance.
In this embodiment, the route information that can be passed at the current time is acquired. However, by specifying the time (date and time), the route information that can be passed at the specified time can also be acquired.

Embodiment 4 FIG.
Next, the case where the destination is specified by selecting and inputting a category will be described below with reference to FIG. It should be noted that the possible locations in the map data 14a are classified in advance into categories such as stations, hospitals, department stores, post offices, etc., and stored as additional information 14c in the storage unit 14 of the server 4 shown in FIG. deep. FIG. 11 shows a display screen on the mobile terminal 2.
First, the user photographs and reads the two-dimensional barcode 1 indicating the current position using the reading unit 9 having the photographing means of the mobile terminal 2, and then uses the input device 10, for example, “within 5 km” or the like.
