Abstract

Un système de guidage routier dynamique (DTGS) fait l'objet d'un brevet international. Le DTGS intègre des comptages automatiques associés au trafic (ATC), une modélisation macroscopique de demande de trajet (TDM), et une technique de modélisation mésoscopique de réseau - attribution de trafic dynamique (DTA) servant à optimiser des plans en route avec anticipation par rapport au temps pour des automobilistes. Ces plans comprennent des choix optimaux de parcours en temps réel, les heures de départ et d'arrivée basées sur une condition d'anticipation de circulation le long du parcours de façon à réduire à un minimum le temps de trajet réel vécu. Un traitement informatique en nuage, la technologie associée à l'information de l'Internet mobile et des dispositifs mobiles personnels sont utilisés comme mémoire de données et comme outils de communication pour une intégration aux GPS existants. L'invention revendique un traitement technique innovant et faisable permettant de réaliser le DTGS de façon, respectivement, à réduire plus efficacement à un minimum les temps de trajet vécus par les automobilistes, les retards et les coûts et, par conséquent, le DTGS améliore la performance de système de transport en diminuant les gros embouteillages et la pollution de l'air grâce au système.
