PURPOSE: A numerical map manufacturing system for posting GPS based ground objects is provided to precisely transmit the forward traffic situation of running vehicles in the real time. CONSTITUTION: A numerical map manufacturing system comprises the following steps: A GPS artificial satellite(1100) broadcasts a GPS signal. A unmanned indication board broadcast part(1300) is installed in a reference point domain of roadside and receives the GPS signal. The unmanned indication board broadcast part traces vehicles(1200) driving within the reference point domain by rolling around and broadcasts the traffic situation of the surroundings to the vehicles. A vehicle driving part(1400) is installed in a vehicle, receives the GPS signal and the situational data signal from the unmanned indication board broadcast part, and outputs them to a numerical map as an image. A central server of a Korea highway corporation(1600) connects to the unmanned indication board broadcast part through a communication network(1500) and provides the peripheral traffic information corresponding to the information of the unmanned indication board broadcast part. |
