ABSTRACT:
A vehicle detector and classifier comprises a plurality of electrically conductive loops1arranged substantially in a plane perpendicular to a road surface, for detecting vehicle wheels. The loops can be arranged in a transverse, vertical slot2and housed in a flexible enclosure. An electronic circuit3, including an oscillator, can be positioned adjacent each loop1in the slot2to energize and monitor the loop. The detector preferably also includes a conventional loop arranged substantially in the plane of the road surface, for detecting vehicle bodies, and means for superposing the results obtained from the conventional and vertical loops to aid in classifying detected vehicles.
