Abstract

L'invention concerne un système de gestion du trafic (3) permettant de gérer les véhicules (2) qui circulent sur une route à péage (1). Ce système est équipé de dispositifs de communication (20) installés dans les véhicules (2) et de dispositifs de communication (30) installés dans les péages (10) pour l'entrée et la sortie de la route à péage (1). Les péages (10) comprennent des postes de communication (30A) et des postes de contrôle (30B). La communication établie entre les dispositifs installés dans les péages et les véhicules permet le paiement du péage sans recourir à des traitements manuels ni à des tickets. Les postes de contrôle (30B) peuvent arrêter les véhicules dont les dispositifs de communication sont inopérants et leur interdire l'entrée.
