Abstract

L’invention fournit un procédé de détermination d’un état de densité d’un trafic routier en fonction de changements de direction du regard d’un conducteur d’un véhicule au cours de la conduite, le procédé comportant : - alimenter (S1) une intelligence artificielle avec des données pour reconnaitre des changements de direction de regard du conducteur vers au moins un rétroviseur, - compter dans une fenêtre temporelle prédéterminée un nombre courant d’occurrence de changements (S21) de direction de regard caractérisant l’état de densité de trafic routier et comparer ledit nombre courant à un seuil (S22), et si le nombre courant est supérieur au seuil, déterminer une géolocalisation courante du véhicule pour signaler l’état de densité de trafic routier en ladite géolocalisation courante. Figure de l’abrégé : Figure 4The invention provides a method for determining a state of road traffic density as a function of changes in the direction of gaze of a driver of a vehicle while driving, the method comprising: - supplying (S1) an artificial intelligence with data for recognizing changes in direction of gaze of the driver towards at least one rear-view mirror, - counting in a predetermined time window a current number of occurrences of changes (S21) in direction of gaze characterizing the state of density traffic density and comparing said current number to a threshold (S22), and if the current number is greater than the threshold, determining a current geolocation of the vehicle to signal the state of road traffic density at said current geolocation.
