To transmit information contained in signals along a road by installing plural modules along a road lane at intervals, receiving input signals through respective reception parts and transmission parts, and transmitting output signals.
A module 11 receives an input signal 12 through the prescribed radio system of a reception part 13 and outputs an output signal 15 from a transmission part 14, in accordance with the prescribed radio system. These plural modules 11 are installed at intervals along a center line 17 of one lane 16 on the road. The (i-1)-th output signal 15, transmitted from the transmission part 14, provided at the (i-1)-th module 11 is received as an i-th input signal by the reception part 13 of the i-th module and that output signal 15 is transmitted. Similarly, the (i+1)-th module outputs the (i+1)-th signal 15. Thus, by having the respective reception parts 13 and transmission parts 14 of plural modules 11 installed along the road perform input/output of signals, the information can be transmitted along the road.
