A traffic-preemption system and method that communicates an identification code from vehicles to a traffic location. Traffic light control equipment, such as a receiver and traffic light circuit at each intersection of a controlled area, is used to manage headway in mass-transit systems as well as to provide traffic light pre-emption for emergency vehicles. Each traffic light circuit in the controlled area has a receiver located at a traffic location and adapted to receive an identification code from a mass-transit vehicle. A decoding circuit responds to the received identification code by attempting to identify the mass-transit vehicle and determine the timing on the identified route that improves an identified vehicle's headway and/or route timing. In response to determining the timing, a traffic-preemption command is generated for a traffic light on the identified route.

L'invention concerne un système de priorité routière et un procédé permettant de communiquer un code d'identification entre des véhicules et un emplacement de circulation. Un équipement de régulation de feux de circulation, par exemple un récepteur et un circuit de feu de circulation à chaque intersection d'une zone contrôlée, est utilisé pour gérer les temps de passage entre des véhicules de transport en commun et pour assurer la priorité de passage à des feux de circulation à des véhicules d'urgence. Chaque circuit de feu de circulation dans la zone contrôlée comprend un récepteur situé au niveau d'un emplacement de circulation et conçu pour recevoir un code d'identification d'un véhicule de transport en commun. Sur réception du code d'identification, un circuit de décodage tente d'identifier le véhicule de transport en commun et de déterminer la synchronisation nécessaire sur le trajet identifié pour améliorer le temps de passage et/ou le temps de trajet pour le véhicule identifié. En réponse à la détermination de la synchronisation, une commande de priorité routière est générée pour un feu de circulation sur le trajet identifié.
