Abstract A radio transmission method for traffic control signals in city features use of short message transmission service to transmit traffic control signals in traffic monitor system. Its transmission method includes signal transmission and signal receiving. The steps for signal transmission include outputting information from main control board to GSM data interface via interface circuit, converting data by processing unit, sending it to high-frequency unit, converting it to high-frequency signal, sending it to antenna, and emitting the signals. The reverse procedure is performed for signal receiving.
