Title (EN) METHOD AND DEVICE FOR MANAGING ROAD TRAFFIC USING A VIDEO CAMERA AS DATA SOURCE
(FR) PROCEDE ET DISPOSITIF POUR LA GESTION DE LA CIRCULATION ROUTIERE UTILISANT LA CAMERA VIDEO COMME SOURCE D'INFORMATION
Abstract:
(EN) The invention concerns a road traffic management method consisting in acquiring video images using a camera, in extracting part of the data by image processing, and in controlling the traffic light system on the basis of said data. The method consists further in simulating strategies for regulating the traffic lights, evaluating the best regulating strategy and transferring to the traffic light system the regulating strategy selected as the best.
(FR) Procédé de gestion de trafic routier, consistant à acquérir des images vidéo à l'aide d'une caméra, à extraire par traitement d'image une partie de l'information, et à commander des feux tricolores par la prise en compte desdites informations. On réalise en outre une étape de simulation des stratégies de régulation des états des feux, à une étape d'évaluation de la meilleure stratégie de régulation et au transfert des plans de feux correspondant à la meilleure stratégie ainsi sélectionnée.
