Definitions

  • the invention relates to a traffic junction which is operated as a signal-controlled intersection in times of high traffic and is controlled in advance in times of low traffic and is provided with a control which switches between the two modes of operation.
  • the object of the invention is to increase traffic safety.
  • this purpose is achieved in that the traffic junction has on one center a device to be bypassed in the roundabout, which can be switched from one withdrawn state to an active state and vice versa when switching from one mode of operation to the other.
  • the traffic junction configured in this way can be operated as a roundabout instead of an intersection in the times in which it is regulated with right of way.
  • a priority-controlled roundabout is several times more secure than a priority-controlled intersection.
  • the switch from the signal-controlled intersection traffic to the roundabout can be carried out earlier, ie with a higher volume of traffic, than the known switch to the priority-controlled intersection public transport.
  • the solution according to the invention is incomparably cheaper, at least when it comes to converting an existing intersection.
  • the space conditions will not allow conversion into a normal roundabout or the traffic conditions, namely if the intersection lies in the course of a "green wave" during the day.
  • the invention then enables the advantages of a roundabout to be used at least temporarily.
  • the roundabout created according to the invention can, if necessary, avoid detours by prohibiting turning on neighboring nodes, since it enables turning.
  • the facility to be bypassed in the roundabout, its withdrawn state and its active state can be of various types:
  • the device will be at least partially retractable into the ground, preferably to the extent that it consists of a retractable traffic island and / or retractable bollards.
  • a light device for example in the form of a round fence, which could be held on the ground by means of claws, hooks or the like, could also be raised above the traffic level and could then be hung over the intersection like street lamp lanterns.
  • the device could also be withdrawn into a central body, for example a column fixedly arranged at the center of the intersection, from which the device is pivoted out with spokes.
  • the facility did not need to be physically changed as such. It could consist of stationary, mechanical or light technical indicators directing the traffic in the bypass:
  • Luminous arrows could be set up in the ground, which could also be run over in the signal-controlled intersection mode. In order to be more visible, these illuminated arrows could also be arranged on the oblique circumference of a slightly raised circle at the center of the intersection.
  • FIG. 1 shows a traffic junction in operation as a signal-controlled intersection
  • FIG. 2 shows the traffic junction in operation as a roundabout.
  • a circular area 1 In the middle of a crossroads, a circular area 1 is slightly elevated and is visually highlighted by paving. It is edged with sloping curbs so that it can be run over relatively smoothly despite the slight elevation.
  • An interchangeable traffic sign 4 is attached above the usual, normally operated traffic lights 3. It shows the possible directions of travel, but could also be dark.
  • the traffic lights 3 can flash.

Abstract

L'invention concerne un noeud de communication fonctionnant comme un carrefour régulé par signalisation aux heures de pointe, qui présente en son milieu, un dispositif à contourner dans le sens giratoire, que l'on peut faire passer d'un état retiré à un état actif et inversement. Aux heures creuses, le noeud de communication fonctionne en mode 'céder le passage' dans le sens giratoire. L'état retiré correspond par ex. à une position où le dispositif est enfoncé dans le sol ou à une position où il est soulevé au-dessus du niveau de la circulation ou à une position où il se trouve engagé sur un corps central ou à une position d'arrêt où les systèmes de signalisation mécaniques ou lumineux fixes qui guident la circulation dans le sens giratoire sont mis hors service. Le dispositif comprend par exemple un îlot central escamotable et/ou des bittes escamotables. Un noeud de communication fonctionnant en mode 'céder le passage' dans le sens giratoire présente un meilleur degré de sécurité qu'un carrefour fonctionnant en mode 'céder le passage', sans giratoire, mode selon lequel lesdits carrefours fonctionnaient le soir jusqu'à présent. Ce système permet également de faire fonctionner des noeuds de communication en mode 'céder le passage' dans le sens giratoire, là où il n'est pas possible, pour des raisons de sécurité, de mettre les systèmes de signalisation hors service également aux heures creuses. Les temps et les files d'attente qui sont inévitables en cas de circulation régulée par signalisation sont alors réduits et fréquemment entièrement supprimés.
