Magnetic traffic control system

摘要

The device has a set of sensors (C power x i) designed to be arranged along a direction (2). Another set of sensors (C power y j) is arranged along another direction (4), that intersects the former direction at a point at which common sensor (C power xy o) is placed. A microcomputer calculates a relation between a time signature of a vehicle e.g. car, passing above the common sensor and a spatial profile resulting from measurements made by the former sensors. The microcomputer is used to extract the length and the width of the vehicle by thresholding a spatial representation.
