Abstract

Visual regulator device. The invention relates to a visual regulator device in the field of horizontal road marking, which allows the driver of a vehicle to adapt his speed or his direction. The device consists of a set of similar elements (visual regulators) placed on the edges of the roadway. The size of the elements, as well as the interval between each element can be varied. Utilisation of the elements makes it possible to obtain a speed or direction regulator or a deceleration lane, including an adaptation region (3) and a regulation region (4).

Description

DESCRIPTION
La présente invention concerne un dispositif de régulateur visuel dans le domaine de la signalisation horizontale routiére. Elle permet au conducteur de véhicule d'adapter sa vitesse ou sa trajectoire.DESCRIPTION
The present invention relates to a visual regulator device in the field of horizontal road signaling. It allows the vehicle driver to adapt his speed or his trajectory.

La régulation de la vitesse se fait traditionnellement à l'aide de panneaux indiquant les vitesses à respecter (signalisation verticale) ou à l'aide d'obstacles sur la chaussée. La régulation de la trajectoire se fait traditionnellement à l'aide de balises d'accotement.Speed regulation is traditionally done using signs indicating the speeds to be respected (vertical signaling) or using obstacles on the road. The regulation of the trajectory is traditionally done using shoulder markers.

L'oeil humain est sensible à la lumière péripherique de couleur blanche. Le conducteur d'une automobile regarde droit devant lui mais, grâce à la vision périphérique, son attention est attirée par les objets se déplaçant à droite ou à gauche.The human eye is sensitive to white peripheral light. The driver of an automobile looks straight ahead but, thanks to peripheral vision, his attention is drawn to objects moving to the right or left.

Le dispositif est constitué d'un ensemble d'élements similaires (régulateurs visuels, Fig.l) placés sur les bords de la chaussée. La taille des élements ainsi que l'intervalle entre chaque élement sont variables. Le régulateur visuel est de forme triangulaire. I1 est fait de la même matière que les produits utilisés pour les marquages routiers en signalisation horizontale. Le positionnement du dispositif sur la chaussée se fait de maniére à avoir la base du triangle (2) paralléle à l'axe de la chaussée et au bord extréme de la chaussée.The device consists of a set of similar elements (visual regulators, Fig.l) placed on the edges of the road. The size of the elements as well as the interval between each element are variable. The visual controller is triangular in shape. It is made of the same material as the products used for road markings in horizontal signage. The positioning of the device on the roadway is done so as to have the base of the triangle (2) parallel to the axis of the roadway and to the extreme edge of the roadway.

s'il existe une signalisation horizontale en rive de chaussée, la base du triangle est paralléle au marquage au sol, à l'intérieur de la chaussée délimitée par les bandes de rive. La pointe du triangle (1) est orientée en direction de l'axe de la chaussée.if there is horizontal signage at the edge of the carriageway, the base of the triangle is parallel to the ground marking, inside the carriageway delimited by the edge strips. The point of the triangle (1) is oriented towards the axis of the road.

La mise en oeuvre de ces élements permet d'obtenir diverses réalisations fonctionnant sur le même principe.The implementation of these elements makes it possible to obtain various embodiments operating on the same principle.

Placés à distance régulière, les régulateurs visuels forment une zone d'adaptation. L'oeil du conducteur s'adapte à la régularité du message. En réduisant réguliérement l'intervalle entre chaque élement, on obtient une zone de régulation. L'oeil du conducteur qui est adapté à un rythme régulier de message péripherique recheche cette régularité et incite de conducteur à adapter son comportement.Placed at regular distance, the visual regulators form an adaptation zone. The driver's eye adapts to the regularity of the message. By regularly reducing the interval between each element, a regulation zone is obtained. The driver's eye, which is adapted to a regular rhythm of peripheral messages, searches for this regularity and prompts the driver to adapt his behavior.

Ainsi il est possible d'obtenir: - un régulateur de vitesse (Fig.21 comportant une zone d'adaptation dont la longeur est à calculer en fonction de la vitesse pratiquée et une zone de régulation de longueur dépendante de la vitesse que l'on désire obtenir [ Exemple: à l'approche d'une agglomération, d'une intersection ou d'une zone dangereuse].Thus it is possible to obtain: - a speed regulator (Fig. 21 comprising an adaptation zone whose length is to be calculated according to the speed practiced and a length regulation zone dependent on the speed that is wishes to obtain [Example: when approaching a built-up area, an intersection or a danger zone].

- un régulateur de trajectoire Fig.3] qui est l'application du régulateur de vitesse dans une courbe avec la particularité de faire varier la taille des élements visuels en fonction de la courbure de la trajectoire E Exemple: virage particuliérement accidentogéne]. - a trajectory regulator Fig.3] which is the application of the speed regulator in a curve with the particularity of varying the size of the visual elements as a function of the curvature of the trajectory E Example: particularly accident-causing turn].

- un couloir de ralentissement [Fig.43 qui est l'application du régulateur de vitesse avec la particularité de faire varier la taille des élements visuels inversement proportionnellement à la vitesse à obtenir de maniére à canaliser les véhicules dans un couloir [ Exemple: à l'approche d'un poste de péage ou d'un contrôle douanier ]. - a slowdown corridor [Fig.43 which is the application of cruise control with the particularity of varying the size of the visual elements inversely proportional to the speed to be obtained so as to channel the vehicles in a corridor [Example: at l 'approach to a toll booth or customs control].
