Abstract
A stationary communication device (SCD) is placed at a predetermined position to form a communication area covering vehicles traveling on a road. A vehicular communication device (VCD) is mounted on a vehicle for communicating with the SCD when the vehicle enters in the communication area. The SCD divides sound guidance data into a plurality of sound data blocks of predetermined communication frames and transmits the divided sound data blocks successively. The VCD receives the divided sound data blocks transmitted from the SCD, and requests the SCD to transmit specific sound data block again when the VCD fails to receive this specific sound data block, thereby issuing a sound guidance using the received sound data blocks including the specific sound data block transmitted again.
