An information processing apparatus which is configured to access a database in which a characteristic of a person and advertisement information are associated with each other for each one in an area group within a movement range of a moving object, and configured to control a movement of the moving object, the information processing apparatus comprising: a detection unit configured to detect a specific person that exists within a predetermined distance from the moving object; an acquisition unit configured to acquire a characteristic of the specific person detected by the detection unit; an extraction unit configured to extract, from the database, specific advertisement information about a specific area in a movement route to a destination point of the moving object based on the characteristic of the specific person acquired by the acquisition unit; and an output unit configured to output the specific advertisement information extracted by the extraction unit.

Useful data is transmitted to a terminal existing in a transportation vehicle. A communication apparatus installed in the transportation vehicle and configured to transmit the data to the terminal existing in the transportation vehicle includes a data selection unit and an illumination unit. The data selection unit acquires location information indicating a location of the transportation vehicle in which the terminal exists and which is traveling. Based on the acquired location information, the data selection unit selects approaching-location data related to a location ahead of a current location of the transportation vehicle in a traveling direction from a plurality of pieces of data related to the location. The illumination unit transmits, as a modulated light signal, a signal comprising the approaching-location data.
