[0007]
According to a seventh aspect of the present invention, in any one of the second to sixth aspects, the AHS system includes a road database unit that holds road linear information of the corresponding section and information about road conditions or road surface conditions. . It is preferable that the external connection means, the control judgment means, and the road database means are provided in AHS center equipment provided in an AHS system.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0009]
One embodiment is shown in FIG. Regarding each means, apparatus, equipment, etc., there are a plurality of patterns as to which of the processing equipment I of the existing information display equipment A and the AHS roadside equipment II or the AHS center equipment III of the AHS system B. Here, as shown in FIG. 1, the processing equipment I comprises a weather condition transmitting means 1, a construction situation transmitting means 2, an accident situation transmitting means 3, and a transmission content processing means 4. In addition, a control judging means 5, an information display means 6. External connection means 7 is provided. The AHS roadside facility II includes a road condition detecting means 8, a road surface state detecting means 9, a roadside processing means 10, and an information transmitting means 11. The AHS center facility III includes a database means 12, a control determining means 13, and an external connecting means 7. I have.
[0010]
