To provide a travel state discrimination device capable of accurately discriminating a two-wheel vehicle from a four-wheel vehicle.SOLUTION: A travel state discriminating device includes: a pressure signal acquisition section for acquiring a pressure signal capable of detecting pressure by tires of a vehicle passing a vehicle detection position; a vehicle detection signal acquisition section for acquiring a vehicle detection signal capable of detecting presence/absence of the vehicle based on presence/absence of light reception in a light receiving section of a vehicle detector; a time specification section for specifying an arrival time and passing time of the vehicle based on the vehicle detection signal; an estimation section for estimating whether the vehicle is the two-wheel vehicle based on a waveform pattern of the pressure signal; a silhouette acquisition section for acquiring a vehicle body silhouette of the vehicle to be obtained by arranging the vehicle detection signals on a temporal axis when the vehicle is estimated to be the two-wheel vehicle; and a discrimination section for discriminating whether the vehicle is the two-wheel vehicle based on the vehicle body silhouette.SELECTED DRAWING: Figure 4

    【課題】二輪車と四輪車とを精度よく判別することができる走行状態判別装置を提供する。【解決手段】走行状態判別装置は、前記車両検知位置を通過する車両のタイヤによる押圧を検出可能な押圧信号を取得する押圧信号取得部と、車両検知器の受光部の受光の有無に基づき前記車両の存在の有無を検出可能な車両検知信号を取得する車両検知信号取得部と、前記車両検知信号に基づいて前記車両の到達時刻および通過時刻を特定する時刻特定部と、前記押圧信号の波形パターンに基づいて前記車両が二輪車であるか否かを推定する推定部と、前記車両が二輪車であると推定された場合に、前記車両検知信号を時間軸上に並べて得られる前記車両の車体シルエットを取得するシルエット取得部と、前記車体シルエットに基づいて前記車両が二輪車であるか否かを判別する判別部と、を備える。【選択図】図4
