  "textContent": "In a vehicle-mounted positional information indication system, the latitude and longitude position coordinates of the present position of a working vehicle for road maintenance on which the positional information indication system 1 is mounted is computed by a GPS device based on signals received by a GPS receiver 3 through a GPS antenna 2 from GPS satellites and is transmitted to a microcomputerized circuit 4. The microcomputerized circuit 4 picks up information of and the latitude and longitude position coordinates of a corresponding marker post or road sign based on the position of the working vehicle computed by the GPS device, and transmits the picked-up information of and the latitude and longitude position coordinates of the corresponding marker post or road sign to an output device 6 and an external port 7. The output device 6 displays the transmitted information to inform an occupant on the working vehicle, whereby the occupant can accurately know the information indicated by the marker posts and the road signs. When a communicating device is connected to the external port 7, the information can be transmitted to a remote location. When a recording device is connected to the external port 7, the information can be recorded (Fig. 1).",
