A signaling and traffic control system which is capable of a vehicle (2) determining its own absolute position along a guideway (21) based on information received from the wayside (25) using an inductive loop or beacon system (26) in conjunction with the distance traveled according to the onboard tach generator(s) (12), and report its position to a wayside control system (Fig. 3) whereby the wayside control system (Fig. 3) reports to the vehicle (2), as part of its communications message, the location of the closest forward obstacle. Based upon this information, the vehicle (2) controls itself safely based upon its characteristics as contained in a topographical database (106) and a vehicle database (108).

Système de surveillance du trafic et de localisation permettant à un véhicule (2) de déterminer sa position absolue le long d'une voie (21) en se fondant sur les renseignements reçus d'un poste fixe (25) utilisant un système à boucle d'induction ou de balise (26) corrélativement avec la distance parcourue selon le tachymètre à bord (12). Le véhicule transmet alors sa position à un système de contrôle de poste fixe (Fig. 3). Par ailleurs, ce système (Fig. 3) transmet au véhicule (2), dans son message de communications, l'emplacement de l'obstacle le plus rapproché. € l'aide de ces renseignements, le véhicule (2) se contrôle de manière sécuritaire selon ses caractéristiques stockées dans une base de données topographiques (106) et une base de données sur le véhicule (108).
