    Abstract: An object is to enable a user to more readily design a maintenance plan according to the type of an abnormality of road. A first abnormal section that is a road section having a road condition of a first abnormality and a second abnormal section that is a road section having the road condition of a second abnormality that is different from the first abnormality are detected, based on vehicle information from a plurality of vehicles. Out of roads in a displayed map, the first abnormal section is provided with the state information in a first display mode, and the second abnormal section is provided with the state information in a second display mode that is different from the first display mode. The first abnormal section and the second abnormal section provided with the state information are displayed in a display device.

    Abstract: A road surface damage detection device is configured to calculate, for each of road sections, a maximum variation rate that is a maximum value of a variation amount of a wheel speed per unit time in each of vehicles. Next, the device is configured to periodically select, for each of the road sections, a maximum value from the maximum variation rate of each of the vehicles in a first prescribed period, set the selected maximum value as a section maximum variation rate, and determine whether or not the road surface damage has occurred by comparing the section maximum variation rate with a threshold. The device sets the threshold, for each of the road sections, based on a behavior of each of the vehicles in a second prescribed period or based on the behavior of each of the vehicles when a predetermined condition is satisfied.
