<P>PROBLEM TO BE SOLVED: To provide a road-vehicle communication device capable of reliably preventing the missing of positional information. <P>SOLUTION: A road-vehicle communication device 300 which informs a position of an object moving on a road to an on-vehicle device 400, comprises: a data receiving section 310 that obtains measured position of the object; a vehicle position prediction section 330 that obtains a prediction position of the object based on a predetermined movement pattern; a prediction error determination section 340 that determines whether an error of prediction position with respect to the measured position is within a predetermined range; and a data transmission section 360 that, when the error is out of the predetermined range, transmits a piece of information which represents the measured position to the on-vehicle device 400; and when the error is within the predetermined range, a piece of information which represents that the error is within the predetermined range in place of the measured position to the on-vehicle device 400. <P>COPYRIGHT: (C)2012,JPO&INPIT |
