Abstract:
1. A transit information provision device which provides transit information, said transit information provision device comprising: a transit event information acquiring unit operable to acquire transit event information which expresses a transit-related event; a transit information provision unit operable to provide the transit information to a user, the transit information relating to the transit event information; an information provision format storage unit operable to store the transit information provided by said transit information provision unit and a provided location which expresses a traveling point at which the transit information is provided by said transit information provision unit; a position information extraction unit operable to successively extract position information which indicates a present position of the user; a movement history storage unit operable to store a sequence of the extracted position information as a movement history; a route acceptance unit operable to accept an anticipated movement route for the user; a detourable point calculation unit operable to calculate a detourable point where the anticipated movement route accepted by said route acceptance unit is avoided, based on the transit information and the provided location stored by said information provision format storage unit and the anticipated movement route; an information recognition judgment unit operable to judge a likelihood of recognition, the likelihood of recognition being a degree of certainty of recognition by the user of the transit information stored by said information provision format storage unit; an information recognition history storage unit operable to store the likelihood of recognition judged by said information recognition judgment unit; a detour traveling judgment unit operable to judge whether the user has intentionally followed the anticipated movement route or intentionally detoured, using the likelihood of recognition stored by said information recognition history storage unit, based on the provided transit information stored by said information provision format storage unit and the movement history stored by said movement history storage unit, and judge that the user has intentionally detoured from the anticipated movement route when the provided location stored by said information provision format storage unit is before the detourable point calculated by said detourable point calculation unit; a transit information provision rule calculation unit operable to calculate a rule for providing the transit information using transit event information about the case in which it is judged by said detour traveling judgment unit that the user has intentionally followed the anticipated movement route, and transit event information about the case in which the user is judged to have intentionally detoured by said detour traveling judgment unit; and an information provision control unit operable to, when new transit event information is acquired, control the provision of transit information related to the new transit event information by said transit information provision unit, based on the rule.
