Abstract: A communication control device (5) includes: a vehicle information acquiring unit (41) to acquire vehicle information including communication performance information indicating performance of wireless communication in each of a plurality of vehicles (V); a data assignment unit (42) to assign individual pieces of data (D) included in a data group (DG) collected by a vehicle group (VG) to respective selected vehicles (V) among the plurality of vehicles (V) on the basis of the performance of the wireless communication; a data distribution unit (43) to execute control to distribute a piece of data (D) included in the data group (DG) to a corresponding one of the plurality of vehicles (V) by the wireless communication on the basis of a result of the assignment by the data assignment unit (42); and a transmission control unit (44) to execute control to transmit one of the pieces of data (D) which is assigned to a representative vehicle to a server (2) by the wireless communication.

Abstract: A remote operation device that remotely operates a mobile object by communication includes processing circuitry configured to acquire information on non-prime remote operation devices that are allowed to remotely operate the mobile object by the communication; detect a communication delay time in the communication with the mobile object; determine whether or not the detected communication delay time exceeds a delay time determination threshold; determine, when it is determined that the communication delay time exceeds the delay time determination threshold, a switching destination remote operation device from among the non-prime remote operation devices depending on whether or not a switching determination condition is satisfied on a basis of the acquired information on the non-prime remote operation devices; and output switching instruction information for remotely operating the mobile object to the determined switching destination remote operation device.
