Abstract

L'invention concerne une intersection à feux de circulation primaires et secondaires destinée à être utilisée en alternance au niveau d'une intersection secondaire à deux voies opposées, à quatre côtés et à trafic constant, laquelle, grâce à une modification du mode de déclenchement de courant des feux de circulation au niveau de l'intersection, réduit principalement le rapport entre le temps d'attente avant de pouvoir repartir des véhicules allant dans une seule direction d'une intersection à feux de circulation donnée et la durée avant de pouvoir repartir d'environ 3:1 à environ 1:1 de telle sorte que le taux d'utilisation par rapport à une unité de temps de la chaussée, c'est-à-dire le nombre total de véhicules passant à travers un même tronçon de chaussée pendant une unité de temps, est multiplié par 2 à 3, ce qui permet de résoudre les problèmes d'embouteillages urbains résultant d'une médiocre efficacité de déclenchement des feux de circulation.
