Abstract

La présente invention concerne un procédé de commande d'un feu de signalisation comprenant les étapes suivantes consistant : si un feu de signalisation correspondant à une route est dans un état d'arrêt de circulation, à collecter une image d'un véhicule sur la route lorsqu'un temps restant d'un état stationnaire diminue jusqu'à un temps prédéfini, la route croisant d'autres routes au niveau de l'intersection ; à compter, à partir de l'image, un nombre de véhicules sur la route à libérer ; à calculer, en fonction du nombre de véhicules à libérer, un temps de déplacement requis permettant aux véhicules à libérer de se déplacer sur l'intersection ; et lorsque le temps restant de l'état d'arrêt de circulation diminue jusqu'à zéro, à commuter le feu de signalisation correspondant à la route sur un état d'autorisation de circulation, et à maintenir l'état d'autorisation de circulation en fonction du temps de déplacement et à commander des états de feux de signalisation correspondant aux autres routes de manière correspondante. L'invention concerne en outre un appareil de commande de feu de signalisation, un dispositif, et un support d'informations lisible par ordinateur. La présente invention libère efficacement des ressources routières, et permet une circulation plus fluide au niveau de l'intersection.
