Vehicle-based predictive data transmission system and method for traffic state analysis

A vehicle () includes: a plurality of sensors (S); an acquisition section () that acquires detection data from the plurality of sensors (S); a prediction section () that uses a trained model () to predict a future state of the vehicle () on the basis of detection data (D) and that outputs a prediction result for the future state as prediction data (D); and a communication section () that transmits, to a server , usage information which is based on either the detection data (D) or the prediction data (D), after transmitting the usage information, the communication section () transmitting subsequent usage information on the basis of a determination result indicating whether it is possible to transmit the subsequent usage information.
