PROBLEM TO BE SOLVED: To provide a device that generates data for specifying a useful content with high accuracy when detecting a running vehicle on the basis of the measured value of strain that occurs in a traffic passage structure due to the running of a vehicle, and a data generation method, a program, and a recording medium.SOLUTION: A vehicle detection device of the present invention divides the time-series data of measured values of strain occurring on a floor slab that are measured using a strain gauge (S1) into a plurality of periods on a time base, and allocates a window to each period (S2). In a window, out of a plurality of windows, in which the temporal change of measured values of strain does not exceed a threshold (NO in S4), a reference point is set on the basis of the average value of measured values within the window (S5), and in a window in which the threshold is exceeded (YES in S4), a maximum compression point is set to the reference point (S7). A reference line is specified by performing an interpolation arithmetic using the reference point (S8), and the time-series data is corrected on the basis of a difference between the measured value of strain and the reference line (S9).SELECTED DRAWING: Figure 6

    【課題】車両の走行に伴い交通路構造物に生じた歪みの測定値に基づき、走行車両を検出する際の有用な成分を精度良く特定するためのデータ生成する装置、データ生成方法、プログラム及び記録媒体を提供する。【解決手段】車両検出装置は、歪み計を用いて測定S1された床版に生じた歪みの測定値の時系列データを時間軸上で複数の期間に区分し、各期間にウィンドウを割り当てるS2。複数のウィンドウのうち、歪みの測定値の時間的な変動が閾値を超えていないウィンドウにおいてはS4NO、そのウィンドウ内の測定値の平均値に基づき基準点を設定しS5、閾値を超えているウィンドウにおいてはS4YES、最大圧縮点を基準点に設定するS7。基準点を用いた補間演算を行うことにより基準線を特定しS8、歪みの測定値と基準線との差分に基づいて時系列データを補正するS9。【選択図】図6
