INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

An information processing device includes: a communication unit mounted on a moving object and communicates directly with the moving object and another moving object or communicates indirectly with the moving object and the another moving object via a fixed and non-moving communication device; and a controller configured to control the direct communication and the indirect communication performed by the communication unit. The controller is configured to: determine a priority of a message generated by the moving object based on information requiring attention of the another moving object; select at least one of the direct communication or the indirect communication based on the determined priority; and transmit the message by the selected at least one of the direct communication or the indirect communication.
