Abstract

Procédé mis en œuvre par ordinateur de gestion du trafic routier d’une zone routière (Z) découpée en une pluralité de secteurs (S1,…,Si,…,Sn), dans lequel, pour chaque secteur (Si), un contrôleur centralisé (20) calcule une probabilité d’évitement (PSi,t) correspondant à la fraction de véhicules devant éviter ledit secteur (Si), pour fluidifier le trafic dans la zone routière (Z) et établit au moins une carte d’évitement centralisée (30) associant chacune des probabilités d’évitement (PSi,t) calculées au secteur (Si) correspondant, etle système de positionnement et d’aide à la navigation (13) de chacun des véhicules (121) présents dans la zone routière, transcrit la carte d’évitement centralisée (30) en une carte d’évitement personnalisée (40), en effectuant un tirage aléatoire à partir de la probabilité d’évitement (PSi,t), pour calculer un itinéraire final de plus courte durée (41) en fonction de la carte d’évitement personnalisée (40).Figure de l’abrégé : Figure 3A computer-implemented method of road traffic management of a road zone (Z) divided into a plurality of sectors (S1,…,Si,…,Sn), in which, for each sector (Si), a centralized controller (20) calculates an avoidance probability (PSi,t) corresponding to the fraction of vehicles that must avoid said sector (Si), to make traffic more fluid in the road zone (Z) and establishes at least one centralized avoidance map ( 30) associating each of the avoidance probabilities (PSi,t) calculated with the corresponding sector (Si), andthe positioning and navigation aid system (13) of each of the vehicles (121) present in the road zone, transcribes the centralized avoidance map (30) into a personalized avoidance map (40), by randomly drawing from the avoidance probability (PSi,t), to calculate a final route of shorter duration (41 ) based on the custom avoidance map (40).Abstract figure: Figure 3
