In a preferred embodiment, a memory is provided which is connected to the car phone to store the traffic information in each case and they show to the first time or again accordingly Query.

In einer Weiterbildung der Erfindung ist nicht nur vor gesehen, daß Verkehrsmeldungen, wie sie beispielsweise von Zentralverkehrsrechnern, von Polizei-Einsatzfahrzeu gen und ähnlichem angegeben werden, über den Organisa tionskanal weitergereicht werden, sondern umgekehrt läßt sich durch eine entsprechende Logikeinheit auch die Be wegung des Fahrzeuges erfassen und somit abfragen, ob es beispielsweise in einem Stau steht. In one embodiment of the invention is not only seen that traffic reports, such as those gen of central traffic computers, of police Einsatzfahrzeu and the like are given, are passed channel gives about the organization of, but can reversed by a corresponding logic unit and the loading movement of the capture the vehicle and therefore query whether it is for example in a traffic jam. Diese Informationen, die automatisch erfaßt werden und sich aus der Geschwin digkeit und ggf. auch aus der Feststellung, an welchem Ort sich das Fahrzeug befindet, zusammengesetzt sind, können - analog oder noch günstiger digital - an die Zentrale weitergeleitet werden, um dort von einem Rech ner ausgewertet zu werden, der aus der Vielzahl der Einzelinformationen ein Gesamtbild über die Verkehrsbe lastung z. This information, which are automatically detected and speed from the Geschwin and possibly also from the determination of where the vehicle is located, are assembled - can be forwarded to the headquarters to there by a - analog or even cheaper digital to be evaluated computing ner, the one of the plurality of pieces of information an overall picture of the utilization Verkehrsbe z. B. eines bestimmten Straßenzuges gewinnt. As a particular stretch of road wins. Diese von dem Rechner in der Zentrale ermittelte Ver kehrssituation kann, sozusagen als Rückkoppelung, wieder an die Autofahrer zurückgegeben werden, so daß eine wei tere Belastung eines bereits überlasteten Straßenzuges vermieden werden kann. can this traffic situation Ver determined by the computer in the office, so to speak, as a feedback, be returned to the driver, so that a white tere burden an already congested road train can be avoided.

In einer weiteren Ausgestaltung ist die Kombination der Informationen sowohl von einer Verkehrsleitzentrale als auch von den Einzelfahrzeugen denkbar, wobei hinzukommt, daß durch das Autotelefonsystem stets eine Standortbe stimmung der einzelnen mobilen Telefone stattfindet, so daß die Ortung von Verkehrsknotenpunkten und Stellen, in denen der Verkehr zum Erliegen gekommen ist, möglich ist. In another embodiment, the combination of the information is feasible both from a traffic control center as well as the individual vehicles, said add is that by the car telephone system always takes place locational humor of the individual mobile phones, so that the localization of transport nodes and places in which the traffic has come to a standstill, is possible.

Da ein Autotelefonsysstem zellular aufgebaut ist, ist die Verkehrsdurchsage für einen sehr engen und genau abgrenzbaren Bereich möglich, so daß dem Autofahrer wirklich die nur ihn unmittelbar betreffenden Verkehrs nachrichten zugeleitet werden können. Since a Autotelefonsysstem is structured cellular, the traffic announcement for a very narrow and accurately definable range is possible, so that the driver really is the traffic that directly affect only him messages can be forwarded. Damit ist eine hochgradig individualisierte Informationsversorgung möglich. Thus, a highly individualized information supply is possible.

Durch das erfindungsgemäße System kann in der ersten Aufbaustufe ein mit geringem Aufwand erstellbares System zur gezielten Verkehrsinformation geschaffen werden, da der Organisationskanal zwischen der Zentrale und den einzelnen Telefonen ohnehin vorhanden ist und für die Übertragung von digitalen Daten zur Verfügung steht, ohne daß er überlastet wird. By the inventive system, a erstellbares with little effort targeting system traffic information, in the first assembly stage can be provided since the control channel between the central office and the individual phones is already present and is available for the transmission of digital data, without being overloaded , Der mit der Codierung und die Codierung der übermittelten Nachrichten verbundene Aufwand ist vertretbar. The overhead associated with coding and the coding of messages transmitted is acceptable.

In einer zweiten Aufbaustufe kann durch die Informatio nen vom Fahrzeug eine sehr effektive Überwachung des Verkehrs erfolgen, da größere Ansammlungen von stehenden Fahrzeugen sofort erfaßt werden. In a second construction stage can be carried out by the vehicle a very effective monitoring of traffic through the information it, as larger clusters of stationary vehicles can be detected immediately. Diese Überwachung kommt auch den Fahrzeugen zugute, die nicht mit Autotelefonen ausgerüstet sind, denn ein Stau beispielsweise auf der Autobahn wird auf diese Weise sehr schnell und frühzei tig erfaßt und kann durch entsprechende Runkfunkmeldung sofort an Autofahrer, die Verkehrsfunk hören, weiterbe richtet werden. This monitoring is also the vehicles benefits that are not equipped with car phones, because a traffic jam, for example, on the highway is detected very quickly and frühzei tig in this way and can by appropriate Runkfunkmeldung immediately to motorists who hear traffic, will continue editing done.
