  "textContent": "A road surface information providing apparatus includes an information acquisition unit, a road surface condition estimation unit, a risk map generation unit, and a transmission unit. The information acquisition unit acquires vehicle information from at least one vehicle with a wheel detected as being idling among vehicles that are traveling in a predetermined region, and acquire weather information about a surrounding area around the at least one vehicle. The predetermined region includes the surrounding area around the at least one vehicle. The road surface condition estimation unit generates road surface information about an estimated condition of a road surface in the predetermined region on the basis of the vehicle information and the weather information. The risk map generation unit generates a risk map in which the road surface information is correlated with map information. The transmission unit transmits the risk map to the vehicles traveling in the predetermined region.",
