mesure de param\u00e8tres de performance discrets afin de d\u00e9terminer si un seuil d\u2019entretien ou de s\u00e9curit\u00e9 avait \u00e9t\u00e9 atteint.<\/p>\r\n                    <p class=\"description-text\">Cependant, cette approche pr\u00e9sente une limite importante : elle ne signale les sections de voie qu\u2019une fois le seuil atteint, alors m\u00eame que ces sections peuvent se d\u00e9t\u00e9riorer progressivement pendant une longue p\u00e9riode avant d\u2019atteindre ce point critique.<\/p>\r\n                    <p class=\"description-text\">Le LRAIL\u2122 de Pavemetrics\u00ae renverse cette logique en allant au-del\u00e0 des mesures ponctuelles pour offrir une d\u00e9tection proactive des changements dans les zones cl\u00e9s de la voie ferr\u00e9e.<\/p>\r\n                    <p class=\"description-text\">Cette m\u00e9thode permet d\u2019identifier les probl\u00e8mes d\u00e8s leur apparition, bien avant qu\u2019ils n\u2019atteignent un seuil n\u00e9cessitant un avertissement de vitesse ou une fermeture de voie.<\/p>\r\n                    <p class=\"description-text\">L\u2019intelligence artificielle du LRAIL aligne automatiquement les passages r\u00e9p\u00e9t\u00e9s et analyse les donn\u00e9es 2D et 3D afin de d\u00e9tecter les changements entre deux inspections successives.<\/p>\r\n                    <p class=\"description-text\">Le syst\u00e8me peut identifier aussi bien les changements positifs (r\u00e9sultant d\u2019op\u00e9rations d\u2019entretien) que les changements n\u00e9gatifs (signes de d\u00e9gradation). <strong>Exemples de changements d\u00e9tectables :<\/strong><\/p>\r\n                    <ul class=\"bullet-list\">\r\n                        <li>Inventaire des attaches :

que des changements dans leur sch\u00e9ma d\u2019implantation.<\/li>\r\n                        <li>Traverses en bois : \u00e9valuation du classement (grading) et de l\u2019angle

suivi du niveau de ballast et du taux d\u2019encrassement.<\/li>\r\n                        <li>Joints : mesure de l\u2019\u00e9cartement des joints et du boulonnage des barres d\u2019assemblage.<\/li>\r\n                        <li>Voie : d\u00e9tection des changements de gabarit (\u00e9cartement des rails), de d\u00e9vers transversal et d\u2019alignement.<\/li>\r\n
