In step ST104, the mobile terminal device 20 performs a notification information display process. The mobile terminal device 20 displays the position of the candidate vehicle on the map image displayed on the display unit 201 based on the received response notification or update information. In addition, when the vehicle management device 40 indicates the passing frequency prediction result of an empty vehicle, the mobile terminal device 20 gives an instruction to move to an area where the empty vehicle passing frequency prediction result or the empty vehicle passing frequency is high. The movement instruction may be given using the voice input/output unit 202.

Also, in the notification information display processing, the display scale of the map image is adjusted based on the position indicated by the notification information and the self position. For example, the display scale is adjusted so that the own position and the position of the candidate vehicle can be displayed on the map image. In addition, the display scale is adjusted so that the self-position and the area where the empty vehicle passes frequently are displayed on the map image. In this way, by adjusting the display scale, it becomes possible to easily confirm the areas where the candidate vehicles and the empty vehicles pass frequently. In this way, the mobile terminal device 20 performs the display process of the notification information and proceeds to step ST105.

In step ST105, the mobile terminal device 20 determines whether or not it has boarded. The mobile terminal device 20 returns to step ST103 when it is not determined that the user has got in the vehicle, and transmits the boarding notification to the vehicle management device 40 when it is determined that the user has got in the vehicle and ends the process. In addition, when the user performs a use end operation, the boarding notification may be transmitted to the vehicle management device 40 as the completion of the vehicle use request.
