To prevent erroneous counting with respect to a false vehicle signal in which a so-called block division occurs.SOLUTION: A vehicle counting device 1 comprises: a radar sensor unit 10 which transmits a radio wave signal periodically from an obliquely upper side towards a search region of a predetermined width in a traveling direction and receives a reflection signal from a vehicle being traveled in the search region; a measurement unit 22 for measuring a location of a target from the received reflection signal; a vehicle identification unit 23 which identifies a vehicle signal by applying grouping processing to the measured target; a tracking unit 24 for tracking the travel of the identified vehicle signal for each period; and a vehicle counting unit 25 for counting the number of vehicle signals passing a counting zone which is set inside of the search region. In a case where the first identification of a vehicle signal is performed at the downstream side in the traveling direction inside of the search region, the vehicle counting unit 25 prohibits the counting of the vehicle signal.SELECTED DRAWING: Figure 3
【課題】いわゆるブロック割れを生じた偽車両信号に対する誤計数を防止する。【解決手段】車両計数装置1は、走行方向の所定幅の探知領域に向けて斜め上方から周期的に電波信号を送信し、探知領域を走行中の車両からの反射信号を受信するレーダセンサ部10と、受信した反射信号から物標の位置を計測する計測部22と、計測した物標に対してグループ化処理を施して車両信号を特定する車両特定部23と、前記特定された車両信号の走行を周期毎に追跡する追跡部24と、前記探知領域内に設定された計数域を通過する車両信号を計数する車両計数部25とを備える。車両計数部25は、車両信号の最初の特定が前記探知領域内の走行方向下流側で行われた場合、当該車両信号の計数を禁止する。【選択図】図3
