1. An information processing device configured to construct a traffic digital twin in a virtual space based on data received from a plurality of devices, the digital twin being time-synchronized with a real space, the information processing device comprising a processor configured to:
acquire information about provision of a service provided to at least one of the devices by an application, the acquired information including information about a required degree of completion of the traffic digital twin that is required to enable the service by the application;
set an update cycle for updating the traffic digital twin based on the required degree of completion, wherein the update cycle is set longer when the required degree of completion is within a first range than when the required degree of completion is within a second range, the second range having a lower limit value that is greater than an upper limit value of the first range;
transmit information indicating a data transmission cycle to the devices in response to setting the update cycle for updating the traffic digital twin, the data transmission cycle having the same duration as the update cycle;
receive the data transmitted from the devices in accordance with the data transmission cycle, the received data including data for constructing the traffic digital twin;
update the traffic digital twin in accordance with the update cycle using the received data;
acquire a current degree of completion of the updated traffic digital twin;
determine whether the current degree of completion is a target value that is predetermined based on the acquired information about the provision of the service; and
reset the update cycle of the updated traffic digital twin in response to determining that the current degree of completion is not the target value,
the update cycle being reduced in a case where the current degree of completion is smaller than the target value, and
the update cycle being increased in a case where the current degree of completion is greater than the target value.
