The search result display means 34 displays a list of building attribute information obtained by the search. When a character string that partially matches the character string in the input field is hit by the above search, the search result display unit 34 displays the names of these buildings as a list, as shown in FIG. When the user selects and inputs a building in the list, the selected building display means 28 displays the selected and input building in an exaggerated or enlarged form than the standard form at a corresponding position on the background map, and also displays the background. The attribute information of the building is displayed in a balloon from the corresponding position on the map.

The vehicle traffic record display means 36 displays the vehicle traffic record information that the vehicle has traveled on the background map in an overlapping manner. As mentioned above, roads may be damaged and impassable during a disaster. Therefore, for example, the vehicle traffic record information providing service shown in Non-Patent Document 1 is used to acquire the vehicle traffic record information. From the acquired vehicle traffic record information, it is possible to estimate the impassable points and the passable points. By displaying the vehicle traffic record information on the background map in an overlapping manner, it is possible to easily grasp the roads or the like that can be traversed. As a result, the user can set the route to the target building quickly and efficiently.

Next, the operation and action of the above configuration will be described.
