An ultrasonic-based road safety system comprises ultrasonic transceivers arranged in the middle of a road. The transceiver ends of the ultrasonic transceivers face the right side of the vehicle running direction. The ultrasonic transceivers are connected with a processor, and the processor is connected with an LED and a memory. The ultrasonic-based road safety system judges whether a vehicle passes by according to the interval of ultrasonic between transmitting and receiving, and gives hints in different time periods after a vehicle passes by so as to enable the driver of a vehicle behind to have a general knowledge of the situation and maintain a safe distance.
