<p>PROBLEM TO BE SOLVED: To provide an in-vehicle DSRC/VICS transmitter receiver which adapts to both a DSRC service and a service by an optical beacon of a VICS, with simple circuit structure from which a circuit involved in a radio wave beacon is removed.SOLUTION: The in-vehicle DSRC/VICS transmitter receiver includes: an antenna part (1) for performing transmission/reception of a DSRC signal, reception of an optical reception signal, and transmission of an optical transmission signal; and a signal processing part (2) for generating a DSRC signal and an optical transmission signal, transmitting the signals to the antenna part, generating road traffic information on the basis of each of the DSRC signal and the optical reception signal received by the antenna part and outputting the information to the outside. At least one of the optical transmission signal and the optical reception signal is transferred through a coaxial line (5) arranged between the antenna part and the signal processing part, in order to transfer the DSRC signal.</p> |
