Reflection multiplier radio wave marker system and traffic system

   
   

A reflection multiplier radio wave marker system which comprises a plurality of transmit antennas mounted on board a vehicle for transmitting electric wave signals in a first frequency; a reflection multiplier radio wave marker installed in the surface of a road, which reflects and transmits the electric wave signal of first frequency after multiplying it into an electric wave signal of a second frequency; and a receive antenna mounted on board the vehicle for receiving the electric wave of second frequency. The system specifies the location of a vehicle in a traffic lane by making use of the second frequency electric wave signal reached from a marker. It can detect a marker throughout substantially the entire width range of a vehicle. A traffic system using the marker system is also disclosed. The function of specifying the location of a radio wave marker is performed throughout the entire vehicle width.
