Loop sensing apparatus for detecting vehicles travelling along a lane of a roadway comprises an outer loop producing a region of magnetic field with the same polarity and an inner loop sized to fit within this region of constant polarity. The inner loop provides two regions of opposite polarity, so that field produced by the outer loop has a null effect on the inner loop. Detection circuitry energises both the outer and inner loops individually for separate detection of vehicles passing over the loops.

L'invention concerne un dispositif de détection de boucle servant à détecter des véhicules se déplaçant sur une voie d'une chaussée, qui comporte une boucle extérieure produisant une zone de champ magnétique présentant la même polarité, et une boucle intérieure conçue pour s'insérer dans cette zone de polarité constante. La boucle intérieure comporte deux zones de polarité opposée, de sorte que le champ produit par la boucle extérieure a un effet nul sur la boucle intérieure. Un circuit de détection excite les boucles extérieure et intérieure individuellement pour détecter séparément les véhicules traversant les boucles.
