Abstract
A navigation device (10) having measurement means (12) for measuring both (i) the position of travel of a mobile body driven by a driver and (ii) travel information as information on traveling conditions; determination means (22) for determining the degree of danger based on the measured traveling conditions; point processing means (22 etc.) for adding/subtracting a point corresponding to the determined degree of danger; providing means (19, 20, etc.) for providing the driver with a message; acquisition means (16 etc.) for acquiring accident information; and control means (22 etc.) for controlling, based on the acquired accident information, the providing means so that a predetermined message corresponding to the point obtained by addition/subtraction is provided.

14. A navigation apparatus for a movable body comprising:
-
an obtaining device for obtaining accident information including at least position information which indicates an occurrence position at which an accident has occurred, from an accident history database in which information about accidents in the past are accumulated; a detecting device for detecting a drive operation of the movable body at a travel position of the movable body driven by a driver; a holding device for connecting and holding a plurality of types of items about the drive operation of the movable body and a score; a judging device for judging whether or not the detected drive operation is the same as any one drive operation included in the plurality of types of items; a score processing device for (i) adding the score corresponding to the one drive operation if the detected drive operation is the same as the one drive operation and (ii) or subtracting the score corresponding to the one drive operation if the detected drive operation is not the same as the one drive operation; a score totalizing device for calculating a total value of the added or subtracted score; a providing device for providing a message according to the total value for the driver; and a controlling device for controlling said providing device to provide the message corresponding to the total value, if a distance between (i) the occurrence position indicated by the position information included in the obtained accident information and (ii) the travel position, is less than a predetermined value. - View Dependent Claims (15, 17, 18, 19, 20)

16. A navigation method for a movable body comprising:
-
an obtaining process of obtaining accident information including at least position information which indicates an occurrence position at which an accident has occurred, from an accident history database in which information about accidents in the past are accumulated; a detecting process of detecting a drive operation of the movable body at a travel position of the movable body driven by a driver; a holding process of connecting and holding a plurality of types of items about the drive operation of the movable body and a score; a judging process of judging whether or not the detected drive operation is the same as any one drive operation included in the plurality of types of items; a score processing process of (i) adding the score corresponding to the one drive operation if the detected drive operation is the same as the one drive operation and (ii) subtracting the score corresponding to the one drive operation if the detected drive operation is not the same as the one drive operation; a score totalizing process of calculating a total value of the added or subtracted score; a providing process of providing a message according to the total value for the driver; and a controlling process of controlling said providing process to provide the message corresponding to the total value, if a distance between (i) the occurrence position indicated by the position information included in the obtained accident information and (ii) the travel position, is less than a predetermined value.
