Abstract

Il s'agit d'un panneau de limitation de vitesse qui change la vitesse affichée selon les conditions météorologiques : présence ou non de pluie. Ii a |’avantage d'étre a bas cout en utilisant un systéme mécanique simple. Ii est composé d'un bac de collecte de l'eau de pluie qui est relié a une plaque d'affichage qui défile verticalement, selon ia position du bac, pour afficher soit la vitesse iimite normale soit la vitesse iimite sous la pluie.This is a speed limit sign that changes the posted speed according to the weather conditions: presence or absence of rain. It has the advantage of being low cost by using a simple mechanical system. It consists of a rainwater collection tank which is connected to a display plate that scrolls vertically, according to the position of the tank, to display either the speed limit iimite normal speed iimite in the rain.
