Embodiment approach 1
[0104] figure 1 It is a schematic diagram showing the outline of the road surface state prediction system 1 according to the first embodiment.
[0105] figure 1 A case where two mobile bodies 1A and 1B are traveling on a road 3 is schematically shown. The road 3 leads to the inside of the tunnel through the bridge 4 and the exit 5 of the tunnel. The mobile body 1A is about to pass through the bridge 4, and the mobile body 1B is coming out of the exit 5 of the tunnel.
[0106] The mobile bodies 1A and 1B are, specifically, vehicles such as four-wheeled vehicles and two-wheeled vehicles, and travel on the road 3 . Furthermore, at least one of the mobile bodies 1A and 1B may be a flying body called a drone.
[0107] The mobile objects 1A and 1B detect moisture on the road surface of the road 3 while traveling on the road 3 to obtain moisture information related to the moisture on the road surface. The mobile bodies 1A and 1B communicate with the information center 2 wireless...
Embodiment approach 2
[0243] Next, for the road surface state prediction system according to Embodiment 2, use Figure 13 Be explained.
[0244] Figure 13 It is a block diagram showing the configuration of the road surface state prediction system 301 according to this embodiment.
[0245] Such as Figure 13 Shown, the road surface state prediction system 301, and figure 2 Compared with the illustrated road surface state prediction system 1 , the distribution unit 370 is newly provided. Specifically, the information center 2 includes a distribution unit 370 .
[0246] The distribution unit 370 distributes distribution information including the prediction result of the prediction unit 220 . The purpose of distribution is a vehicle in motion, a road manager, a traffic manager, a traffic information operator, a transportation operator, or a postal operator, etc.
[0247] For example, when receiving a distribution request from a distribution destination, the distribution unit 370 distributes dis...
Embodiment approach 3
[0254] Next, for the road surface state prediction system according to Embodiment 3, use Figure 14 Be explained.
[0255] Figure 14 It is a block diagram showing the configuration of the road surface state prediction system 302 according to this embodiment.
[0256] Such as Figure 14 Shown, the road surface state prediction system 302, and Figure 4 Compared with the road surface state prediction system 1b shown, the difference is that a distribution unit 370 , a notification unit 380 , a determination unit 381 , and a search unit 382 are newly provided. and, Figure 14 The illustrated mobile body 1A may also include an environmental information obtaining unit 130 .
[0257] Such as Figure 14 It is shown that in the road surface state prediction system 302, the distribution unit 370 of the information center 2 distributes the distribution information to the plurality of mobile bodies 1C and 1D. The mobile bodies 1C and 1D are mobile bodies that do not have the functio...
