る回路とより成る車両台数計測装置。 A device for detecting the passage of a vehicle, and a treadle that has multiple rows of contacts in the direction of vehicle travel that operate in response to the pressure of the wheels and is laid on the road surface to detect the axle of the vehicle. In a vehicle counting device that uses a contact signal to determine whether a passing vehicle is moving forward or backward and counts the number of vehicles, the traveling direction of a passing vehicle is determined based on the output pattern of the contact signal of the tread plate when the pedal is pressed, and the direction corresponding to the determined direction is determined for each determination. a circuit that reversibly counts the output signal of this circuit according to the discrimination direction and generates an output when it reaches a predetermined value; and a circuit that counts the counter output and counts the number of backward vehicles; A circuit that operates upon receiving the contact signal, detects the axle from the contact signal, counts it, and generates an output when a predetermined value is reached, a circuit that passes this output in accordance with the output of the counter, and a circuit that counts the output of this circuit. A vehicle counting device consisting of a circuit that counts the number of vehicles moving forward.
