To accurately discriminate a vehicle passing through a predetermined area regardless of mounting/non-mounting of an RFID tag.SOLUTION: A passing vehicle discrimination system 1 comprises: an optical sensor 20 which irradiates a side face of a vehicle passing through a predetermined area A with laser light, and detects reflected light of the laser light; a reading device 30 which reads information on an RFID tag mounted on the vehicle; and an arithmetic processing device 41 which detects the vehicle passing through the predetermined area A on the basis of a detection result of the optical sensor 20, and acquires a read result of the reading device 30. The arithmetic processing device 41, when the information on the RFID tag can be read within a predetermined time with timing at which the vehicle passing through the predetermined area A is detected as a base point, discriminates that the vehicle detected at the timing is a vehicle on which the RFID tag is mounted, and when the information on the RFID tag cannot be read within the predetermined time, discriminates that the vehicle detected at the timing is a vehicle on which the RFID tag is not mounted.SELECTED DRAWING: Figure 4

    【課題】RFIDタグの搭載有無に関わらず所定領域を通過する車両を正確に判別する。【解決手段】通過車両判別システム1は、所定領域Aを通過する車両の側面にレーザ光を照射し、当該レーザ光の反射光を検出する光センサ20と、当該車両に搭載されたRFIDタグの情報を読み取る読取装置30と、光センサ20の検出結果に基づいて所定領域Aを通過する車両を検知すると共に、読取装置30の読み取り結果を取得する演算処理装置41と、を備える。演算処理装置41は、所定領域Aを通過する車両を検知したタイミングを基点とする所定時間以内にRFIDタグの情報を読み取れた場合、当該タイミングに検知された車両をRFIDタグが搭載された車両であると判別し、所定時間以内にRFIDタグの情報を読み取れなかった場合、当該タイミングに検知された車両をRFIDタグが搭載されていない車両であると判別する。【選択図】図4
