La présente invention concerne un dispositif de sécurité routière susceptible Il fi de remplacer le dispositif de prévention du système P. 1. A. C. 'Prévention et
Interdiction des Accès à Contresens'objet du brevet 9409237 du 26.07. 94. The present invention relates to a road safety device capable of replacing the prevention device of the system P. 1. AC 'Prévention et
Prohibition of Access to Contresens subject to patent 9409237 of 26.07. 94.
ART ANTERIEUR Il 1/
Le dispositif'prévention'P. LA. C. était mis en oeuvre dans les premiers mètres des bretelles pour éviter leur accès à contresens, ceci cependant pouvait, en cas de panique du conducteur du véhicule s'avérer dangereux pour les véhicules circulant dans le bon sens et occasionner des embouteillages voire des carambolages préjudiciables à la sécurité routière. PRIOR ART There 1 /
The prevention device P. THE. C. was implemented in the first meters of the ramps to avoid their access in the wrong direction, this however could, in the event of panic of the driver of the vehicle prove dangerous for vehicles traveling in the right direction and cause traffic jams or even pileup detrimental to road safety.
Le dispositif P. LA. C. (prévention et interdiction) ne peut-être mis en oeuvre que dans les cas où la bretelle d'accès est suffisamment longue pour permettre le positionnement des systèmes de détection par boucles. The device P. LA. C. (prevention and prohibition) can only be implemented in cases where the access ramp is long enough to allow positioning of the loop detection systems.
L'installation du système nécessite une Infrastructure lourde avec une arrivée électrique de 220 Volts au milieu de la bretelle, des traversées de routes pour alimenter les éléments de sécurité : barrière, feux sur la voie de dégagement, sur le barrière, à l'entrée à contresens de la bretelle et des travaux pour incorporer les boucles magnétiques dans le revêtement bitumeux de la bretelle
Le coût occasionné par les travaux de terrassement pour i' alimentation est important par rapport au devis général. The installation of the system requires a heavy infrastructure with an electrical supply of 220 volts in the middle of the ramp, road crossings to supply the safety elements: barrier, lights on the escape route, on the barrier, at the entrance. against the flow of the ramp and work to incorporate the magnetic loops in the bituminous coating of the ramp
The cost of earthworks for food is significant compared to the general estimate.
Par contre des études menées par l'Institut National de Recherche Sur les Transports et leur sécurité (I. N. R. E. T. S) montrent que 90 % des contresens seraient arrêtés par Le module de prévention. On the other hand, studies carried out by the National Institute for Research on Transport and their safety (I. N. R. E. T. T. S) show that 90% of the wrong way would be stopped by the prevention module.

Tous ces éléments ont conduit le demandeur à réfléchir sur un nouveau système de détection et d'alerte susceptible d'éliminer tous les inconvénients évoqués ; à savoir : - prévenir le conducteur du véhicule avant qu'il ne s'engage sur la bretelle à contresens, - doter le dispositif d'une alimentation électrique autonome pour réduire les coûts d'infrastructure, - disposer un système capable avec des informations fiables, de donner l'alerte au centre responsable de la sécurité routière ou à d'autres organismes pour prendre toutes les mesures susceptibles de garantir la sécurité des autres véhicules. All these elements led the applicant to reflect on a new detection and alert system capable of eliminating all the drawbacks mentioned; to know: - to warn the driver of the vehicle before it engages on the slip road, - to provide the device with an autonomous electrical supply to reduce infrastructure costs, - to have a capable system with reliable information , to give the alert to the center responsible for road safety or to other organizations to take all measures likely to guarantee the safety of other vehicles.
ETUDE DU NOUVEAU SYSTEME DE PREVENTION (Fia 1 & 2)
Un radar de type DOPPLER (A) est fixé à une hauteur de 3 mètres sur un mat 1 de 4 mètres de haut situé à environ 5 mètres de la bretelle d'accès. Il permet de déterminer le sens de circulation et la vitesse du véhicule en rapprochement dans le lobe défini F1 pour le radar avant que le véhicule ne pénètre sur la bretelle d'accès. STUDY OF THE NEW PREVENTION SYSTEM (Fia 1 & 2)
A DOPPLER type radar (A) is fixed at a height of 3 meters on a mast 1 4 meters high located about 5 meters from the access ramp. It makes it possible to determine the direction of circulation and the speed of the vehicle approaching in the defined lobe F1 for the radar before the vehicle enters the access ramp.
Le rapprochement à l'intérieur du lobe, enregistré sur une carte électronique de gestion numérique des données est gardée en mémoire pendant une dizaine de secondes, provoque l'éclairage d'un panneau 2 réfléchissant 'sens interdit'situé sur le mat à la hauteur d'un conducteur assis, ainsi qu'un signal sonore pour attirer l'attention des conducteurs dont les réflexes seraient ralentis par un taux d'alcoolémie supérieur à la normale requise. The reconciliation inside the lobe, recorded on an electronic digital data management card is kept in memory for ten seconds, causes the lighting of a panel 2 reflecting 'prohibited direction' located on the mat at height of a seated driver, as well as an audible signal to attract the attention of drivers whose reflexes would be slowed by a higher than normal blood alcohol level required.
Un faisceau F2 de ce radar (A) est orienté vers l'arrière. Un autre radar Identique (B) orienté dans la même direction recoupe les informations déjà fournies par (A). Si le véhicule passe dans le lobe en éloignement, la comparaison des 3 impulsions positives va déclencher un message enregistré A beam F2 of this radar (A) is oriented towards the rear. Another identical speed camera (B) oriented in the same direction intersects the information already provided by (A). If the vehicle goes into the lobe away, the comparison of the 3 positive pulses will trigger a recorded message

qui sera transmis par un terminal radio GSM (112 en France) dont l'antenne est située en haut du mat 4.
which will be transmitted by a GSM radio terminal (112 in France) whose antenna is located at the top of mast 4.
Il est à noter que les faisceaux des radars sont réglables pour tenir compte des courbures et des différentes géométries des bretelles, et qu'une caméra vidéo peut être montée pour enregistrer l'infraction. It should be noted that the radar beams are adjustable to take into account the curvatures and the different geometries of the straps, and that a video camera can be mounted to record the offense.
EXAMENS DES CAS. CASE EXAMINATIONS.
Véhicule dans le sens normal : Il aborde le faisceau arrière de A et celui de B dans le sens du rapprochement et le faisceau avant de A en éloignement : pas de signaux. Vehicle in the normal direction: It approaches the rear beam of A and that of B in the direction of approach and the front beam of A in distance: no signals.
Véhicule à contresens : Le rapprochement dans le lobe de détection avant de A déclenche le dispositif de prévention. Si le véhicule stoppe avant la prise à contresens de la bretelle d'accès, après un temps t de rémanence, la procédure d'alerte est levée Par contre, si le véhicule dépasse les radars, B détecte l'éloignement, vérifie la fiabilité de l'information de A et lance la procédure d'alerte au centre d'information. Vehicle in the wrong direction: The approach in the detection lobe before A triggers the prevention device. If the vehicle stops before the opposite ramp is taken, after a period of remanence, the alert procedure is lifted. On the other hand, if the vehicle exceeds the radars, B detects the distance, checks the reliability of A's information and initiates the alert procedure at the information center.
Même en cas de croisement sur la bretelle le système enregistre uniquement le véhicule à contresens. Even in the event of a crossing on the ramp, the system only registers the vehicle in the wrong direction.
MISE EN UVRE. IMPLEMENTATION.
Selon l'implantation en agglomération (rocade, périphérique) ou en rase campagne, ce système de prévention peut selon le cas être raccordé électriquement au secteur ou alimenté d'une manière autonome par une batterie de 90 A/H rechargée par un panneau solaire situé en haut du mat 3. Depending on the location in built-up areas (ring road, ring road) or in the open country, this prevention system can, depending on the case, be electrically connected to the mains or powered autonomously by a 90 A / H battery recharged by a solar panel located at the top of the mast 3.
Des contrôles constants de dysfonctionnement des radars, panneau lumineux, batterie sont détectés et les alertes de non fonctionnement sont transmises aux services compétents. Constant checks of radar, light panel and battery malfunctions are detected and non-operating alerts are sent to the relevant departments.
