To provide a road surface information collection system capable of corresponding to a rapid change of a road surface state.SOLUTION: A road surface information collection system includes: multiple vehicles for collecting basic data of road surface unevenness information; and a data center for analyzing basic data acquired from the vehicles via radio communication so as to constitute road surface unevenness information and distributing the information via radio communication. The system can perform a rapid change correspondence function in such manners that: basic data including vibration data and position information is transmitted to the data center when the vibration data being equal to or more than a predetermined threshold is detected by the vehicle in a place where existing road surface unevenness information does not exist; the data center that has received the basic data performs a transmission request of the basic data to subsequent vehicles passing through the position; the threshold is substantially canceled in the subsequent vehicles that have received the transmission request; and the basic data is transmitted from all the subsequent vehicles passing through the position to the data center.SELECTED DRAWING: Figure 6
【課題】 路面状況の急変に対応可能な路面情報収集システムを提供する。【解決手段】 路面凹凸情報の基礎データを収集する複数の車両と、前記車両から無線通信を介して取得した基礎データを解析して路面凹凸情報を構成し、無線通信を介して配信するデータセンタと、を含み、既存の路面凹凸情報が存在しない場所では、車両に所定の閾値以上の振動データが検出された場合に当該振動データと位置情報を含む基礎データがデータセンタに送信され、当該基礎データを受信したデータセンタは、当該位置を通過する後続車両に基礎データの送信要求を行い、当該送信要求を受信した後続車両は前記閾値が実質的に解除され、当該位置を通過する全ての後続車両から基礎データがデータセンタに送信される、急変対応機能を実行可能である。【選択図】 図6
