Un modèle animé (190) est projeté sur la voie de circulation (150, 60) en fonction de l'indice de risque. Les modèles animés (190) sont de préférence réalisés sous la forme de graphiques mobiles. L'unité d'interprétation (250) peut influencer l'amplitude, l'intensité et/ou la fréquence du modèle animé (190) en fonction de l'indice de risque.
