To provide a road surface information collecting system that classifies inappropriate data for analysis of the situation of a road surface and attains increase in the accuracy of estimating the situation of the road surface.SOLUTION: A road surface information collecting system 1 includes: a vehicle 10 for collecting basic data on the situation of a road surface; and a data center 20 for analyzing the basic data acquired from the vehicle and obtaining information on the road surface. The vehicle includes: vehicle position detection means 11; vehicle information acquisition means 12 for acquiring vehicle information including the speed of the vehicle; vibration detection means 13; and basic data forming means 15 for forming basic data obtained by relating the vibration data detected by the vibration detection means to the position, the speed, and the rank of the vehicle. The data center includes: a data processing unit 22 for reducing the influence of the speed and the rank of the vehicle from the basic data; a data analysis unit 23 for obtaining the road surface information by analyzing the processed data; and a road surface information database 24 for storing the road surface information. A vehicle of which speed is not smaller than a predetermined value when the vehicle is at the detection position is the object of the analysis and filtering is performed.SELECTED DRAWING: Figure 1

    【課題】路面状況の分析に不適格なデータを分別し路面状況推定精度の向上が見込める路面情報収集システムを提供する。【解決手段】路面情報収集システム1は、路面状況の基礎データを収集する車両10と、車両から取得した基礎データを解析して路面情報を得るデータセンタ20とを含む。車両は、車両位置検出手段11と、速度を含む車両情報取得手段12と、振動検出手段13と、振動検出手段に検出された振動データを、車両位置、車両速度及び車格情報と関連させた基礎データを構成する基礎データ構成手段15とを備える。データセンタは、基礎データから車両速度及び車格の影響を低減するデータ処理部22と、処理したデータを解析して路面情報を得るデータ解析部23と、路面情報を格納する路面情報データベース24とを備える。検出位置における車両速度が所定値以上の場合は解析対象とし、所定値未満の場合は、フィルタリングする。【選択図】図1
