Abstract

La présente invention concerne un système et un procédé basés sur un point d'accès de l'Internet des objets destinés à publier des informations, consistant : à rapporter une position d'arrêt temporaire sur une certaine route ainsi qu'un identifiant de véhicule d'un véhicule dans lequel un terminal de communications de véhicule est situé sur une plateforme d'analyse et d'agrégation de données au moyen d'un point d'accès à l'Internet des objets ; la plateforme d'analyse et d'agrégation de données sélectionnant, à partir d'un grand nombre de véhicules d'accès, des véhicules qui sont dans un état de conduite, qui accèdent à la plateforme d'analyse et d'agrégation de données au moyen d'un point d'accès à l'Internet des objets, et qui se déplacent sur ladite route dans la direction vers la position d'arrêt temporaire afin de constituer un second groupe de véhicules ; à calculer la distance immédiate entre la position d'arrêt temporaire et la position immédiate de chaque véhicule cible dans le second groupe de véhicules, et à envoyer à un conducteur d'un véhicule cible des informations de notification qui comprennent la distance immédiate entre la position d'arrêt temporaire et la position immédiate du véhicule cible ainsi que l'identifiant de véhicule du véhicule dans lequel se trouve le terminal de communications de véhicule. Un conducteur de véhicule peut être rapidement informé qu'un véhicule est temporairement arrêté à une certaine distance sur une route de telle sorte que le conducteur peut ralentir à l'avance de façon à empêcher un accident de la circulation.
