Abstract:
To improve the detection accuracy of rutting.SOLUTION: An arithmetic operation device 14 includes: a vehicle behavior information acquisition unit 40 for acquiring vehicle behavior information and traveling direction information for a vehicle at detection of the vehicle behavior information; a route direction information acquisition unit 42 for acquiring route direction information; a road surface state information acquisition unit 44 for acquiring information on an amount rutting on a road; and a learning unit 46 for performing machine learning of correspondence between the vehicle behavior information and the amount of rutting by using, as teacher data, the vehicle behavior information and the amount of rutting at the position which are extracted based on an angle formed by the traveling direction of the vehicle and an extension direction of the road. The learning unit 46 uses, as the teacher data, vehicle behavior information corresponding to a traveling direction of the vehicle for which the angle formed by the extension direction of the road is greater than a prescribed value and the amount of rutting for the corresponding position, and excludes, from the teacher data, vehicle behavior information corresponding to a traveling direction of the vehicle for which the angle formed by the extension direction of the road is equal to or less than the prescribed value and the amount of rutting amount for the corresponding position.SELECTED DRAWING: Figure 3
