PROBLEM TO BE SOLVED: To provide a technique with which it is possible to measure the weight of a vehicle and accurately calculate the speed of this vehicle.SOLUTION: A plurality of axle load sensors 3a-3d arranged in line in the traveling direction of a vehicle are connected to an axle load sensor connection unit 11, to which the measurement signals of the axle load sensors 3a-3d are inputted. Vehicle detection sensors 2i, 2o arranged on the upstream and/or the downstream side of the plurality of axle load sensors 3a-3d being in line in the traveling direction of a vehicle are connected to a vehicle detection sensor connection unit 12, to which the detection signals of the vehicle detection sensors 2i, 2o are inputted. A weight calculation function unit 31 processes the measurement signals of the axle load sensors 3a-3d connected to the axle load connection unit 11 and calculates the weight of the vehicle detected by the vehicle detection sensors 2i, 2o. A speed calculation function unit 33 calculates, on the basis of a target section speed, the passage time of the vehicle when it has passed by the vehicle detection sensors.SELECTED DRAWING: Figure 1

    【課題】車両の重量の計測とともに、この車両の速度を精度良く算出できる技術を提供する。【解決手段】軸重センサ接続部11には、車両の走行方向に並べて配置された複数の軸重センサ3a〜3dが接続され、軸重センサ3a〜3dの計測信号が入力される。車両検知センサ接続部12には、車両の走行方向に並んでいる複数の軸重センサ3a〜3dの上流側、または下流側の少なくとも一方に配置された車両検知センサ2i、2oが接続され、車両検知センサ2i、2oの検知信号が入力される。重量算出機能部31は、軸重センサ接続部11に接続されている軸重センサ3a〜3dの計測信号を処理して、車両検知センサ2i、2oが検知した車両の重量を算出する。速度算出機能部33は、対象区間速度に基づいて車両検知センサの通過時における当該車両の通過速度を算出する。【選択図】図1
