A vehicle-mounted real-time road condition method and device based on a positional relationship calculation adopt a combination of GPS real-time location and GPRS network real-time transmission. The precision of the GPS real-time location is higher than that of base station location, a server can obtain a specific road segment where a car owner is, the car owner uploads the speed information to the server, and the speed information of the road segment is obtained, so that the real-time road condition information of the road segment can be obtained. A GPRS network is used, it is guaranteed that equipment is real-time online and maintains a connection state with the server, by means of location, the car owner obtains the road condition information of the road segments to be taken through calculation, and the road condition information is broadcast to the car owner through a voice mode, so that the car owner can obtain the road condition information in real time through the equipment, and the relationship between the road condition information and the car owner is closely linked.
