Abstract
(EN)
A mapping method for a spatial time-distance map showing a regional green wave coordinated control effect. The mapping method comprises the following steps: establishing a coordinate system of the spatial time-distance map; determining specific position coordinates of each intersection in the coordinate system of the spatial time-distance map; generating a signal timing scheme time prism of each intersection; determining a green wave bandwidth of each arterial road; and generating driving trajectory lines among the intersections, making green wave bands of the arterial roads, and completing mapping. The movement condition of multiple coordinated vehicle flows can be reflected, the overall green wave coordinated control effect of a regional traffic signal coordinated control scheme is comprehensively displayed, the three-dimensional description of a time-space relationship of the intersections in a road network is achieved by establishing the signal timing scheme time prisms of the intersections, and the establishment of a road network coordinated control optimization model is facilitated. The method is suitable for the field of traffic signal control.

L'invention a pour objet un procédé de cartographie concernant une carte de distance temporelle spatiale présentant un effet de commande coordonnée d'onde verte régionale. Le procédé de cartographie comprend les étapes suivantes : établissement d’un système de coordonnées de la carte de distance temporelle spatiale ; détermination des coordonnées de position spécifiques de chaque intersection dans le système de coordonnées de la carte de distance temporelle spatiale ; génération d’un prisme temporel de schéma de synchronisation de signaux de chaque intersection ; détermination d’une largeur de bande d'onde verte de chaque artère ; et génération de lignes de trajectoire de conduite parmi les intersections, création de bandes d'onde verte des artères, et achèvement du processus de cartographie. La condition de déplacement de multiples flux de véhicules coordonnés peut être reflétée, l'effet de commande coordonnée d'onde verte globale d'un schéma de commande coordonnée de signaux de trafic régional est affiché de manière complète, la description tridimensionnelle d'une relation temps-espace des intersections dans un réseau routier est obtenue par l'établissement des prismes temporels de schéma de synchronisation de signaux des intersections, et l'établissement d'un modèle d'optimisation de commande coordonnée de réseau routier est facilité. La présente invention est applicable au domaine des systèmes de communication intelligents.
