VEHICLE INFORMATION DETECTING SYSTEM USING A CALCULATED TREAD

摘要

A vehicle information detecting system using a calculated tread is provided to identify the tread of a vehicle by implementing a tilted piezo sensor in a road side. A vehicle information detecting system using a calculated tread includes plural loop sensors and plural piezo sensors. The piezo sensors are disposed at a predetermined tilting angle between the loop sensors. The tread of a vehicle is calculated by the tilted piezo sensors. The piezo sensors include a forward piezo sensor(220) and a backward piezo sensor(220'). The forward piezo sensor is disposed in the extended line of the loop sensors in a vertical direction. The backward piezo sensor is disposed at a predetermined tilting angle with respect to the forward piezo sensor.
