Abstract: A route in which a stop position of a delivery vehicle is taken into account is created. When creating a route, for each of one or more delivery destinations, a travel trajectory of a delivery person and a travel trajectory of a delivery vehicle in one or more deliveries made to the delivery destination is acquired, and, for each of the one or more delivery destinations, a transit point for the delivery destination is determined based on a travel trajectory of a delivery person and a travel trajectory of a delivery vehicle in each of one or more deliveries made to the delivery destination.

Abstract: A calculation data storage unit (120) of an accident index calculation apparatus (10) is used together with a map data storage apparatus. A first index acquisition unit (110) of the accident index calculation apparatus (10) acquires information (travel route specification information) for specifying a travel route of a vehicle (60), and acquires a first index by using the travel route specification information and map data stored in the map data storage apparatus (50). The first index is related to a unit road count, which is the number of unit roads included in the travel route per unit travel time. A calculation unit (130) calculates an index (a second index) related to likelihood of an accident (for example, a traffic accident) involving a driver of the vehicle (60) or the vehicle (60).

Abstract: A terminal unit (400) of a navigation system (100) transmits to a server (300) list request information containing a rectangular code corresponding to a predetermined display rectangular area of a travel route map. The terminal unit (400) acquires from the server (300) a server POI list corresponding to the rectangular code of the list request information, and when recognizing that the server POI list contains POI individual information corresponding to terminal base data that is not stored in a terminal base storage area, the terminal unit (400) transmits base data request information about POIID of the POI individual information to the server (300). Upon acquisition of server base data corresponding to the base data request information from the server (300), the terminal unit (400) stores the server base data in the terminal base storage area as terminal base data.

Abstract: The map updating system (100) includes a server unit (400) and a terminal unit (300, 300A, 300B). The server unit (400) has an updated contents recognizer that recognizes updated contents of updated map information and generates updated contents information, a user recognizer that recognizes distribution request information and also recognizes user information containing the distribution request information when determining that the updated contents information contains request contents of the distribution request information, and an information transmitter that transmits the updated map information to the terminal unit (300, 300A, 300B) corresponding to the user information such that the map information can partially be rewritten with a part of the updated map information. The terminal unit (300, 300A, 300B) includes a terminal map updating section that acquires the transmitted updated map information and stores the part of the updated map information in a terminal storage section in a rewritable manner.

Abstract: A stay location connection information register device retains history information including user information and stay location information. A history information searching unit searches history information coincident with a predetermined condition. A stay location connection information generating unit generates link information of the stay location by the unit of the user information with using the history information searched by the history information searching unit. Then, the stay location connection information register unit registers the stay location connection information. In this manner, since the stay location connection information register device generates the link information of the stay location with using the history information, the stay location connection information register device can define a correspondent relation between the stay locations.

Abstract: A navigation apparatus includes map data, a map change information receiving unit and a map display change unit. The map data includes predetermined map information having two modes: an unavailable mode in which the map information is unusable, and an available mode in which the map information is usable. The map change information receiving unit receives change information of the predetermined map information, which is distributed by transmission. On receiving the change information, the map display change unit switches the two modes of the predetermined map information.
