Abstract

L'invention porte sur un système de traitement de données relatives à un véhicule comportant: un capteur de données relatives à au moins l'une des caractéristiques d'un véhicule passant devant, et une unité réceptrice des données capturées, les deux dispositifs étant intégrés dans un même boîtier. L'unité réceptrice emmagasine les données et les communique à des périphériques et/ou à une installation centrale de traitement.
