Abstract

Dispositif permettant de compter et classer les véhicules circulant sur une route. Ce dispositif comprend deux câbles piézo-électriques 1 et 2 disposés transversalement à la chaussée qui délivrent deux signaux dont l'amplitude est fonction du poids et de la vitesse du véhicule, ces signaux étant traités par un micropresseur Il qui commande un multiplexeur 6 recevant également les signaux de boucles magnétiques 3 et 4 de détection de passage.
