Abstract
In an apparatus for the transfer of information in motor vehicle traffic between a fixed-position transmitter-building element near a roadway and a receiver arranged in a vehicle, the transmitter-building element emits a coded information signal and the receiver of the vehicle driving past the transmitter-building element displays information from the information signal in the vehicle. In order to make shielding measures unnecessary, with an uncomplicated supply of energy to the transmitter-building element and small construction costs therefor, the transmitter-building element (1) is built into roadway pavement (12). The energy necessary for transmitting the information signal is received by the transmitter-building element (1) from the vehicle (13) which is driving above it. The receiver (4, 15, 16) has an antenna arrangement (14) which is arranged in a floor area of the vehicle (13) to transfer the necessary transmitting energy to the transmitter-building element (1) and receive the emitted information signal from the transmitter-building element (1).
