Navigation device, navigation method, route data generation program, recording medium containing route data generation program, and server device in navigation system

A navigation apparatus comprising:

• a departure point data acquisition device which obtains departure point data including at least location data of a departure point from which a mobile unit departs;
• a registration device which registers a destination to be reached by the mobile unit;
• a spot data acquisition device which obtains spot data on the registered destination including at least location data indicating the location of the destination, stay length information representing information on an expected stay length at the destination and available time information indicating available dates and times of the destination;
• a storage device which stores map data;
• a generation device which generates route data from the departure point to the destination including at least an expected arrival time at the destination on the basis of the obtained departure point data, the spot data on the registered destination and the map data;
• and
• a route guidance device which performs route guidance from the departure point to the destination on the basis of the generated route data.

A navigation method comprising:

• a departure point data acquisition process which obtains departure point data including at least location data of a departure point from which a mobile unit departs;
• a registration process which registers a destination to be reached by the mobile unit;
• a spot data acquisition process which obtains spot data on the registered destination including at least location data indicating the location of the destination, stay length information representing information on an expected stay length at the destination and available time information indicating available dates and times of the destination;
• a map data acquisition process which obtains map data stored in a storage device;
• a generation process which generates route data from the departure point to the destination including at least an expected arrival time at the destination on the basis of the obtained departure point data, the spot data on the registered destination and the map data;
• and
• a route guidance process which performs route guidance from the departure point to the destination on the basis of the generated route data.

A route data generation program for generating route data relating to route guidance of a mobile unit by a computer, said route data generation program making the computer function as:

• a departure point data acquisition device which obtains departure point data including at least location data of a departure point from which a mobile unit departs;
• a registration device which registers a destination to be reached by the mobile unit;
• a spot data acquisition device which obtains spot data on the registered destination including at least location data indicating the location of the destination, stay length information representing information on an expected stay length at the destination and available time information indicating available dates and times of the destination;
• a map data acquisition device which obtains map data stored in a storage device;
• a generation device which generates route data from the departure point to the destination including at least an expected arrival time at the destination on the basis of the obtained departure point data, the spot data on the registered destination and the map data;
• and
• a route guidance device which performs route guidance from the departure point to the destination on the basis of the generated route data.

A server apparatus in a navigation system, said server apparatus comprising:

• a reception device which receives departure point data including at least location data of a departure point of a mobile unit registered by a terminal device departs, and a destination which is to be reached by the mobile unit;
• a spot data acquisition device which obtains spot data on the registered destination including at least location data indicating the location of the destination, stay length information representing information on an expected stay length at the destination and available time information indicating available dates and times of the destination;
• a storage device which stores map data;
• a generation device which generates route data from the departure point to the destination including at least an expected arrival time at the destination on the basis of the obtained departure point data, the spot data on the registered destination and the map data;
• and
• a route guidance control device which controls route guidance in said terminal device from the departure point to the destination on the basis of the generated route data.
