ROAD SURFACE SITUATION DEDUCTION SYSTEM
To provide a technology of deducing a road surface which becomes slippery on a rainy day.SOLUTION: In a road surface situation deduction system, a road surface information acquisition unit 22 acquires road surface information representing slipperiness of a rolling road surface on a sunny day. A rainfall acquisition unit 26 acquires a rainfall per time and a time having elapsed since it begins raining. A deduction unit 28 deduces a degree of slipperiness of the rolling road surface on a rainy day from the rainfall per time and the time having elapsed since raining starts. A calculation unit calculates an index concerning a condition of the rolling road surface on the basis of a traffic volume on the rolling road surface and a sunny time period immediately before raining starts.SELECTED DRAWING: Figure 3
【課題】雨天時に滑りやすくなる路面を導出する技術を提供する。【解決手段】路面状況導出装置において、路面情報取得部２２は、晴天時の走行路面の滑りやすさを示す路面情報を取得する。雨量取得部２６は、時間当りの雨量と、雨が降り始めてからの時間とを取得する。導出部２８は、時間当りの雨量と、雨が降り始めてからの時間と、路面情報とにもとづいて雨天時の走行路面の滑りやすさの度合いを導出する。算出部は、走行路面の交通量と、雨が降り始める直前の晴天であった期間とにもとづいて、走行路面の状態に関する指標を算出する。【選択図】図３
