Definitions

  • the invention relates to a method for coding cross-road traffic obstructions at digital encoded traffic messages, which as elements to one a street lying place and the extent and the direction contain the traffic obstruction and based on a Place table or a digital map to be decoded.
  • Such a construction and coding of Traffic reports are for example in the CEN EN12313-1 which is based on the standard proposal ALERT C, November 1990, published by the RDS ATT ALERT Consortium.
  • RDS Radio Data System
  • the essential elements of a traffic announcement are the Location of the event and the event. This information is cataloged, that is, to everyone traffic-relevant location and every traffic-relevant event a unique code is assigned. The concatenation of places in a place table along existing roads gives the Course again.
  • TMC Traffic Message Channel
  • TMC messages can not only but with the help of the radio data system also for example within the digital audio broadcasting (DAB), especially in the FI channel (Fast Information Channel).
  • DAB digital audio broadcasting
  • SMS Short Message Service
  • GATS Global Automotive Telematic Standard
  • a TMC message only one location code is used transfer.
  • the direction and the Extent of traffic obstruction sent.
  • the extent indicates how many sections of a road from the traffic obstruction are affected.
  • the direction indicates in which direction the end point of the traffic obstruction lies. All concerned Places must be on the same street.
  • the object of the invention is to obstruct traffic on the Place table based to code so that even those Traffic disruptions that span more than one street extend, decode and in one easy by the user Recordable form can be reproduced.
  • the invention is applicable to branches and crossings, for describing the invention throughout the Expression diversion was used as an intersection as well can be considered as a multiple branch.
  • the inventive method be applied in that the digital coding of the traffic reports after the ALERT-C protocol takes place and that the additional element the label is 12.
  • the method according to the invention is compatible with existing ones Terminals in the sense that no false information be generated. Recipients who do not evaluate the label 12 can receive a reduced amount of information about the cause of the fault and a portion of that of the Disruption affected routes.
  • An advantageous embodiment of the invention Method is that the data field of the label 12th three bits to select the adjacent to the junction Road on which the traffic obstruction stretches one bit for the associated direction and four bits for that direction Extent of extent on this road includes and that another eight bits for the same coding for the case are provided that the traffic is still over extends another road change. It can be preferably provided that when extending the Traffic obstruction over more than three roads for each two more streets encoded an additional label 12 and is transmitted. In this embodiment, the in the label 12 contained 16-bit data field in a particularly favorable manner exploited.
  • the invention further relates to a method for decoding of coded by the method according to the invention Traffic news, which is provided that in a with a place, a street, a direction and an extent provided for a traffic obstruction Traffic message the label 12 is evaluated such that from the intersection of the road coded in the traffic message starting with the road coded in the label 12 and in the direction indicated in the label 12 in the label 12th specified extent a place is determined which, in case that no further extension of the traffic obstruction in the Label 12 is coded, the end of the traffic obstruction means. Is the end of the traffic obstruction not on this road, it can proceed in this way, that when coding another street in the label 12 from the Place table along the further street the place of the end the traffic obstruction is read out.

  • Fig. 2 shows sections of two others Federal highways B65 and B443.
  • AK HB and MG frequently incur traffic obstruction at trade fairs, which can not be coded in ALERT-C without complications.

Abstract

L'invention concerne un procédé pour coder des encombrements affectant plusieurs voies de circulation, dans le cas d'informations routières codées numériquement qui contiennent, sous la forme d'éléments, un emplacement situé sur une voie de circulation, ainsi que l'ampleur et la direction de l'encombrement. Ces informations sont décodées au moyen d'un tableau d'emplacements. Selon le procédé de l'invention, lors de l'annonce d'encombrements s'étendant, en raison de leur ampleur, au-delà d'un embranchement, sur une autre voie de circulation, un autre élément est utilisé pour coder les informations suivantes : embranchements affectés par l'encombrement, direction et ampleur de l'encombrement.

Claims (6)

  1. Procédé pour coder des encombrements routiers sur plusieurs routes, dans le cas de messages routiers codés numériquement et qui contiennent différents éléments, à savoir un endroit situé sur une route et la taille ainsi que la direction de l'encombrement, et qui sont décodés à l'aide d'un tableau de localisation,
    caractérisé en ce que
    lorsqu'on signale des encombrements qui s'étendent sur une autre route au-delà d'une bifurcation du fait de leur taille, le codage est effectué par un élément supplémentaire en indiquant sur quelle route qui bifurque, dans quelle direction s'étend l'encombrement signalé et la taille de l'encombrement.
  2. Procédé selon la revendication 1,
    caractérisé en ce que
    les messages routiers sont codés numériquement d'après le protocole ALERT-C et l'élément supplémentaire est le label 12.
  3. Procédé selon la revendication 2,
    caractérisé en ce que
    la zone de données du label 12 comprend trois bits pour sélectionner la route qui bifurque sur laquelle s'étend l'encombrement, un bit pour la direction correspondante et quatre bits pour la taille de l'extension sur cette route,
    et huit autres bits sont prévus pour un codage identique pour le cas où l'encombrement s'étende encore au-delà d'un autre carrefour.
  4. Procédé selon la revendication 3,
    caractérisé en ce que
    lorsque l'encombrement s'étend sur plus de trois routes, un label 12 est codé et transmis pour deux autres routes à chaque fois.
  5. Procédé pour décoder des messages routiers codés d'après le procédé selon l'une des revendications 2 à 4,
    caractérisé en ce que
    lorsqu'un message routier comprend un endroit, une route, une direction et une taille et concerne un encombrement, le label 12 est exploité de telle manière qu'à partir du croisement de la route codée dans le message routier, à l'aide de la route codée dans le label 12 et dans la direction indiquée dans le label 12, grâce à la taille indiquée dans le label 12 on détermine un endroit qui signifie que l'encombrement prend fin au cas où aucune autre extension de l'encombrement n'est codée dans le label 12.
  6. Procédé selon la revendication 5,
    caractérisé en ce que
    l'endroit où l'encombrement prend fin est lu sur le tableau de localisation le long de l'autre route lorsqu'une autre route est codée dans le label 12.
