Abstract
The present invention relates to a traffic marking and safety radio phonetic warning system. A wireless receiving device is arranged on a vehicle, and is used for receiving encoding digital information emitted by a traffic marker or a wireless information transmitting device nearby and converting the encoding digital information into prestored speech information which is played back by a loudspeaker. When the vehicle runs and is close to a traffic mark on which the transmitting device is installed, the vehicle obtains the voice prompting of the traffic mark through the loudspeaker in advance. Consequently, sound causes a driver's attention before the traffic mark causes the driver's visual attention. Thus, the driver can take measures as early as possible, can avoid possible traffic accidents, and can improve traffic safety.
