May be. In addition, when the moving means is a bicycle, the moving means determination unit 402g has bad weather at a predetermined time (for example, the time to go home) based on weather information included in the moving environment information stored in the movement information database 406a. If it is (for example, rain, storm, snow, etc.), it may be determined that the moving means is not appropriate. In addition, when the moving means is a car, the moving means determination unit 402g has a weather at a predetermined time (for example, a time to go home) based on weather information included in the moving environment information stored in the movement information database 406a. May be determined that the moving means is not appropriate when the weather is in bad weather (for example, storm or heavy snow). Moreover, when the schedule memorize | stored in the movement information database 406a is a plan with drinking (for example, a party or a banquet), and the moving means determination part 402g is a bicycle or a motor vehicle, It may be determined that the moving means is not appropriate.

  And the alerting | reporting information production | generation part 402k is determined that the moving means is not suitable in the movement environment of the user of the navigation apparatus 400 by the moving means determination part 402g in step SG-2 (step SG-2: No). In the moving environment of the user of the navigation device 400, information for notifying the user of the navigation device 400 that the moving means based on the moving means information included in the return information acquired by the return information acquisition unit 402f is inappropriate is generated. (Step SG-3). Here, the notification information generation unit 402k is an alternative route that is a guide route for a round trip between a home and a predetermined point that does not use the moving means based on the moving means information included in the return path information acquired by the return path information acquiring section 402f. Notification information based on the alternative route information generated by the alternative route search unit 402h may be generated. The broadcast information may include the departure time of the alternative route based on the alternative route information generated by the alternative route search unit 402h. The broadcast information may include alternative route information generated by the alternative route search unit 402h.

  On the other hand, the notification information generation unit 402k is determined in step SG-2 that the moving means is appropriate in the moving environment of the user of the navigation device 400 by the moving means determination unit 402g (step SG-2: Yes). ) In the moving environment of the user of the navigation device 400, notification information to the user of the navigation device 400 that the moving means based on the moving means information included in the return path information acquired by the return path information acquisition unit 402f is appropriate. Is generated (step SG-4). Here, the notification information may include return information acquired by the return information acquisition unit 402f. Further, the notification information is generated by the outbound route search unit 402i regarding the outbound route from the home to a predetermined point or destination using the travel unit information based on the travel unit information included in the return route information acquired by the return route information acquiring unit 402f. It may also include the outgoing route information.

  And the alerting | reporting information output part 402m displays the alerting | reporting information produced | generated by the alerting | reporting information generation part 402k on the display part 414 (step SG-5), and complete | finishes a process. Here, when the notification information includes the outbound route information generated by the outbound route search unit 402i, the alert information output unit 402m may further display the departure time of the outbound route included in the outbound route information on the display unit 414. . The broadcast information output unit 402m is further acquired by the forward / return information acquisition unit 402f based on the forward information generated by the forward search unit 402i included in the route guidance information generated by the route guidance information generation unit 402j. Included in the route guidance information generated by the route guidance information generation unit 402j on the map information related to the map including the return route based on the return route information or the alternative route information based on the alternative route information generated by the alternative route search unit 402h. The display unit 414 can superimpose the forward route information, the return route information, the alternative route information, and / or the current location information of the user of the navigation device 400 acquired by the current location information acquisition unit 402a. Thus, route guidance may be executed. Here, the notification information output unit 402m may perform route guidance when a user inputs a route guidance start request via the input unit 418. Further, the notification information output unit 402m may cause the display unit 414 to display display guidance information included in the route guidance information generated by the route guidance information generation unit 402j. Further, the notification information output unit 402m may output voice information corresponding to the display (voice guidance information included in the route guidance information generated by the route guidance information generation unit 402j) via the voice output unit 416. .
