A method and apparatus for guiding a vehicle in which a transmission signal of a position transmitting device installed at key points on a roadside is received by a position receiving device mounted in the vehicle. The apparatus having members for coding position information on the road where the position transmitting device is installed and traffic information including danger information with respect to the road, storing the same, modulating and continuously transmitting the coded information to the vehicle. Also, the apparatus capable of receiving the transmission signal of a corresponding position while the vehicle is moving on the road, and continuously classifying and searching the information and the intensity of the signal. Another part of the apparatus for detecting the current position of the vehicle either by directly using the searched result or by computing a travel distance of the vehicle. The apparatus for informing the current position of the detected vehicle, its heading position, its advancing the direction, a remaining distance to its destination and danger information for guidance.

1. A method for guiding a vehicle in which a transmission signal of a position transmitting device installed at key points on a roadside is received by a position receiving device mounted in the vehicle, comprising the steps of:receiving traffic information for service to a vehicle moving on a road from a traffic information network; receiving position information on the road and the traffic information received from an interface unit as code values and storing the same; modulating the position information and the traffic information as coded and stored in a recording unit, and wirelessly transmitting the same to each vehicle moving in the vicinity of the road; coding the position information on the road and the traffic information obtained by the interface unit, providing it to a recording unit, and controlling the transmitting operation of a first communication module and the receiving operation of the traffic information; receiving the transmission signal as modulated by the position transmitting device, classifying the information and the intensity of the signal from the received signal, and outputting the same; digitizing the intensity of the transmission signal as classified by the second communication module; measuring a travel distance of the vehicle and generating pulses in proportion to the measured travel distance; detecting the determined current position of the vehicle on the basis of the information as classified by a second communication module, the digital value according to the intensity of the signal and the measure pulse, analyzing the data to output a corresponding position information, travel information and danger information, and periodically controlling the operation of the second communication module; and visually and acoustically guiding the position information, the travel information and the danger information obtained by a second microprocessor.
