Abstract
Description
La présente invention concerne un ensemble de signalisation routière, comprenant au moins un moyen de signalisation implanté au voisinage d'une voie de circulation, et communiquant un message. The present invention relates to a road signaling assembly, comprising at least one signaling means located in the vicinity of a traffic lane, and communicating a message.
Ce moyen de signalisation peut être un panneau, dit "panneau de police", formant support pour un message fixe
d'interdiction (concernant le sens de circulation, le stationnement, un type d'usager particulier, etc.),
de limitation (concernant la vitesse, un poids, une hauteur, etc.),
de danger (concernant la configuration de la voie, la proximité d'une école, etc.).This signaling means can be a panel, called "police panel", forming a support for a fixed message
prohibition (concerning the direction of traffic, parking, a particular type of user, etc.),
limitation (concerning speed, weight, height, etc.),
danger (concerning the configuration of the track, the proximity of a school, etc.).
I1 peut également s'agir d'un panneau à message variable signalant par exemple l'existence d'un "bouchon", la présence de verglas, etc. I1 peut encore s' agir d'un feu tricolore, ou monocolore clignotant ou fixe, ces divers exemples n'étant pas limitatifs. It can also be a variable message sign indicating for example the existence of a "plug", the presence of ice, etc. It can also be a three-color, or single-color flashing or fixed light, these various examples not being limiting.
La multiplication des panneaux de signalisation, souvent mêlés, en outre, à des panneaux et enseignes publicitaires, gêne leur perception individuelle par les usagers de la route et il en résulte inévitablement des accidents. Même parfaitement visible, un panneau ou un signal important peut ne pas être vu, si l'attention de l'usager est attirée par un évènement quelconque au moment où il aurait dû voir le panneau ou si, à ce moment, il a été par exemple ébloui par un véhicule circulant en sens inverse. Les conditions atmosphériques (brouillard, pluie violente, etc. The multiplication of road signs, often mixed, in addition, with advertising signs and signs, hinders their individual perception by road users and this inevitably results in accidents. Even perfectly visible, a sign or an important signal may not be seen, if the user's attention is drawn to any event at the time when he should have seen the sign or if, at that moment, he was by example dazzled by an oncoming vehicle. Atmospheric conditions (fog, heavy rain, etc.
sont également à prendre en compte.are also to be taken into account.
En outre, les moyens de signalisation concernant spécifiquement, ou entre autres, les piétons sont inadaptés aux personnes ayant un handicap visuel, à part dans quelques rares cas où les feux de carrefour sont associés à un système émettant un signal sonore continu lorsque le feu est au rouge, et un signal discontinu lorsque le feu est sur le point de repasser au vert. In addition, the signaling means specifically concerning, or inter alia, pedestrians are unsuitable for people with visual impairments, except in a few rare cases where the intersection lights are associated with a system emitting a continuous sound signal when the light is red, and a discontinuous signal when the light is about to change back to green.
La présente invention a pour but de remédier à ces inconvénients, but qui est atteint en ce sens que l'ensemble qu'elle propose est caractérisé en ce que ledit moyen de signalisation est associé à, ou intègre, un émetteur radio de faible portée adapté à émettre un code correspondant audit message, ledit ensemble comprenant, en outre, au moins un récepteur radio adapté à recevoir ledit code et à le traduire en un signal directement perceptible par un usager se trouvant à proximité immédiate dudit récepteur. The object of the present invention is to remedy these drawbacks, which is achieved in the sense that the assembly which it proposes is characterized in that said signaling means is associated with, or integrates, a suitable short range radio transmitter. transmitting a code corresponding to said message, said assembly further comprising at least one radio receiver adapted to receive said code and translating it into a signal directly perceptible by a user being in the immediate vicinity of said receiver.
Dans une première forme d'exécution de l'invention, ledit récepteur est embarqué à bord d'un véhicule et le signal est un signal visuel et/ou sonore perceptible par le conducteur du véhicule. In a first embodiment of the invention, said receiver is on board a vehicle and the signal is a visual and / or audible signal perceptible by the driver of the vehicle.
Pour ce faire, ledit récepteur peut comporter, ou intégrer, un écran d'affichage pour l'énoncé, en clair, dudit message. To do this, said receiver can include, or integrate, a display screen for the statement, in clear, of said message.
Dans une version plus sophistiquée, le récepteur peut être associé à, ou intégré dans, un système d'assistance à la conduite dont est équipé ledit véhicule, système qui comporte un tel écran d'affichage et/ou un synthétiseur de parole. In a more sophisticated version, the receiver can be associated with, or integrated into, a driving assistance system with which said vehicle is equipped, a system which includes such a display screen and / or a speech synthesizer.
Dans une deuxième forme d'exécution de l'invention, le récepteur est adapté à être porté par un piéton, notamment malvoyant ou aveugle. In a second embodiment of the invention, the receiver is adapted to be carried by a pedestrian, in particular visually impaired or blind.
Dans ce cas, le récepteur est associé à, ou intègre, un avertisseur sonore ré-émettant le message selon un mode codé (émission continue ou discontinue, sur un ton ou sur plusieurs tons, etc.). In this case, the receiver is associated with, or integrates, an audible alarm re-transmitting the message according to a coded mode (continuous or discontinuous transmission, in one tone or in several tones, etc.).
En variante, le récepteur pour piéton est associé à, ou intègre, un synthétiseur de parole émettant, en clair, ledit message. As a variant, the pedestrian receiver is associated with, or integrates, a speech synthesizer transmitting, in plain text, said message.
Un exemple de mise en oeuvre de l'invention est décrit ci-après en référence à la figure unique du dessin annexé. An example of implementation of the invention is described below with reference to the single figure of the accompanying drawing.
Cette figure schématise une situation susceptible d'être trouvée à l'entrée d'une voie d'accès à un parking où l'on observe un panneau 1 de limitation de vitesse, indiquant 30 km/h, et un panneau 2 d'interdiction d'accès aux piétons. This figure shows a situation likely to be found at the entrance to an access road to a car park where there is a speed limit sign 1, indicating 30 km / h, and a prohibition sign 2 pedestrian access.
Ces deux panneaux 1 et 2 sont chacun munis d'un émetteur radio, schématisés en 3 et 3' et alimentés par tout moyen convenable, tel que secteur, batterie, photopile, etc. These two panels 1 and 2 are each provided with a radio transmitter, shown schematically in 3 and 3 'and supplied by any suitable means, such as mains, battery, solar cell, etc.
ou toute solution mixte. L'émetteur 3 du panneau 1 émet, sur une fréquence F1 destinée uniquement aux conducteurs de véhicules, une onde portant un code C1 signifiant "vitesse limitée à 30 km/h", tandis que, de son côté, l'émetteur 3' émet, sur une fréquence F2 destinée uniquement aux piétons, une onde portant un code C2 signifiant "accès interdit aux piétons".or any mixed solution. The transmitter 3 of the panel 1 transmits, on a frequency F1 intended only for vehicle drivers, a wave carrying a code C1 meaning "speed limited to 30 km / h", while, for its part, the transmitter 3 'transmits , on a frequency F2 intended only for pedestrians, a wave carrying a code C2 meaning "access prohibited to pedestrians".
Lorsqu'un véhicule 4, équipé d'un récepteur 5 réglé sur la fréquence F1, s'engage dans cette voie, son récepteur 5 est exposé aux ondes émises par les deux panneaux 1 et 2, mais il n'est sensible qu'aux ondes de fréquence F1. Le récepteur 5, qui est de préférence alimenté par la batterie du véhicule, comporte un écran à affichage par cristaux liquides 6 ou tout autre moyen convenable (à diodes électro-luminescentes, à plasma, à décharge fluorescente, à tube cathodique, etc.), écran sur lequel apparaît le message " < 30 km/h". Ce message persiste tant que le véhicule n'est pas contact coupé.Sur route, dans une situation semblable, ce message persisterait tant que le récepteur 5 ne reçoit pas, d'un panneau ultérieurement rencontré, un message "fin de limitation de vitesse" ou un message indiquant une autre valeur de limitation de vitesse, par exemple "vitesse limitée à 110 km/h" ou encore un ordre de substitution par un message considéré comme prioritaire. Le récepteur 5 peut, en effet, être associé à des moyens de gestion adaptés à accorder la priorité d'affichage à tel message plutôt qu'à tel autre, à partir d'une échelle de priorité généralement basée sur le plus ou moins grand danger susceptible de résulter du non respect d'une prescription. When a vehicle 4, fitted with a receiver 5 set to the frequency F1, sets off in this way, its receiver 5 is exposed to the waves emitted by the two panels 1 and 2, but it is only sensitive to F1 frequency waves. The receiver 5, which is preferably powered by the vehicle battery, comprises a screen with liquid crystal display 6 or any other suitable means (with light-emitting diodes, plasma, fluorescent discharge, cathode-ray tube, etc.) , screen on which the message "<30 km / h" appears. This message persists as long as the vehicle is not ignition off. On the road, in a similar situation, this message would persist as long as the receiver 5 does not receive, from a panel subsequently encountered, a message "end of speed limit" or a message indicating another speed limit value, for example "speed limited to 110 km / h" or an order of substitution with a message considered to have priority. The receiver 5 can, in fact, be associated with management means adapted to grant display priority to one message rather than another, on the basis of a priority scale generally based on the greater or lesser danger. likely to result from non-compliance with a prescription.
Le récepteur 5 peut également comporter un voyant de couleur vive 7 et/ou un signal sonore 8 alimenté en cas de réception d'un message de danger grave, tel qu'engagement à contre-sens du véhicule sur une bretelle d'autoroute. The receiver 5 can also include a brightly colored indicator light 7 and / or an audible signal 8 supplied in the event of reception of a serious danger message, such as the vehicle entering the vehicle in the wrong direction on a highway ramp.
Le dessin montre également un autre récepteur 5' de faible poids et de petites dimensions (exagérées sur le dessin) adapté à être porté par un piéton ayant un handicap visuel, par exemple suspendu autour du cou à l'aide d'un cordon 9, et alimenté par pile. Comme le récepteur 5, le récepteur 5' est exposé aux ondes émises par les émetteurs 3 et 3' des panneaux 1 et 2, mais comme il est réglé sur la fréquence F2 il ne perçoit que les ondes portant le code C2, c'est-à-dire le message "accès interdit aux piétons". Ce message est traduit par la mise en oeuvre d'une alarme sonore 8' que comporte le récepteur 5'. The drawing also shows another receiver 5 ′ of low weight and small dimensions (exaggerated in the drawing) adapted to be carried by a pedestrian with a visual handicap, for example suspended around the neck using a cord 9, and battery powered. Like the receiver 5, the receiver 5 'is exposed to the waves emitted by the transmitters 3 and 3' of the panels 1 and 2, but as it is set to the frequency F2 it only perceives the waves carrying the code C2, this is ie the message "access prohibited to pedestrians". This message is translated by the implementation of an audible alarm 8 'that the receiver 5' includes.
Naturellement, il y a des cas où un message intéresse à la fois les conducteurs de véhicules et les piétons, par exemple l'état des feux tricolores d'un croisement. Dans ce cas, l'émetteur dont est muni chaque feu émettra sur les deux fréquences F1 et F2 et le message correspondant aura évidemment un sens différent pour les deux types d'usagers. Naturally, there are cases where a message interests both the drivers of vehicles and pedestrians, for example the state of the traffic lights of a low beam. In this case, the transmitter with which each light is fitted will transmit on the two frequencies F1 and F2 and the corresponding message will obviously have a different meaning for the two types of users.
Pour la sécurité et le confort des piétons malvoyants ou aveugles, il y aura de préférence au moins cinq types de message
a) feu vert : "piétons, ne traversez pas" ; "véhicules, circulez"
b) feu orange : "piétons, préparez-vous à traverser" ; véhicules, ralentissez" ;
c) feu rouge (message transmis uniquement sur la fréquence F1) : "véhicules, stoppez"
d) feu rouge établi depuis un temps de sécurité nécessaire au dégagement des véhicules éventuellement engagés dans le carrefour (message transmis uniquement sur la fréquence F2) : "piétons, traversez"
e) feu rouge en fin de période : "piétons engagés, hâtez-vous, piétons non engagés, ne traversez plus" "véhicules, préparez-vous à repartir" (ce message est équivalent à, et donc rend inutile, l'allumage du feu orange immédiatement avant le retour au feu vert, comme cela est pratiqué dans certains pays. For the safety and comfort of visually impaired or blind pedestrians, there will preferably be at least five types of message
a) green light: "pedestrians, do not cross";"vehicles,move"
b) orange light: "pedestrians, get ready to cross"; vehicles, slow down ";
c) red light (message transmitted only on frequency F1): "vehicles, stop"
d) red light established since a safety time necessary for the clearance of vehicles possibly engaged in the crossroads (message transmitted only on frequency F2): "pedestrians, cross"
e) red light at the end of the period: "pedestrians engaged, hurry up, pedestrians not engaged, no longer cross""vehicles, prepare to leave" (this message is equivalent to, and therefore makes it unnecessary to switch on the orange light immediately before the green light returns, as is the practice in some countries.
En ce qui concerne les piétons, les différents messages sonores peuvent être différenciés par des tons différents et/ou des émissions continues ou discontinues, ou mieux par des messages émis par un synthétiseur de parole. With regard to pedestrians, the different sound messages can be differentiated by different tones and / or continuous or discontinuous transmissions, or better by messages emitted by a speech synthesizer.
Il est bien entendu que la présente invention n'est pas limitée à la forme d'exécution décrite et représentée. En particulier, au lieu d'émettre sur deux fréquences différentes, l'émetteur 3 du panneau 1 pourrait n'émettre que sur une fréquence porteuse, auquel cas le récepteur de chaque catégorie d'usager sélectionnerait et ne mettrait à la disposition desdits usagers que les signaux pouvant les concerner. It is understood that the present invention is not limited to the embodiment described and shown. In particular, instead of transmitting on two different frequencies, the transmitter 3 of panel 1 could only transmit on one carrier frequency, in which case the receiver for each category of user would select and only make available to said users signals that may affect them.
