So ist etwa aus der US 5 317 311 ein System zur Verkehrslageerfassung mit ortsfest installierten Detektoren bekannt. Die Detektoren, deren Sensorik z.B. an Brückenbauwerken über den Fahrspuren einer Autobahn angebracht sind, messen die Durchschnittsgeschwindigkeit der vorbeifahrenden Fahrzeuge und stellen die Zahl der in einer Zeiteinheit passierenden Fahrzeuge fest. Diese erfaßten Daten werden z.B. mittels einer Telefonleitung an eine Verkehrslageerfassungszentrale übertragen. Diese Zentrale übermittelt nun mittels einer entsprechenden Broadcast-fähigen Sendeeinrichtung (z.B. Paging-Netz) die erfaßten Werte der Durchschnittsgeschwindigkeiten an Fahrzeuge, die mit entsprechenden speziellen Verkehrsinformationsgeräten ausgestattet sind. Solche Verkehrsinformationsgeräte weisen einen Empfangsteil mit Antenne und ein Display zur grafischen Darstellung eines Landkartenausschnitts auf. Entsprechend den Standorten der jeweiligen Detektoren werden die übermittelten Werte der Durchschnittsgeschwindigkeiten ortsgerecht im jeweiligen Landkartenausschnitt auf dem Display angezeigt. Auf diese Weise können die Verkehrsteilnehmer aktuell über problematische Bereiche des Straßennetzes informiert Werden.From US 5 317 311, for example, a system for recording the traffic situation is stationary installed detectors known.

Über die Antenne 2 und die Empfängereinheit 3 können die von einem Diensteanbieter z.B. in einem Paging-Netz ausgestrahlten Verkehrsinformationen empfangen werden. Dies ist aber nur möglich, wenn das Zusatzgerät 1 in Empfangsbereitschaft versetzt ist. Hierzu ist es erforderlich, einen Chip 7 in ordnungsgemäßer Form mittels der Chip-Leseeinheit 5 einzulesen. Der Chip 7, der beim Diensteanbieter in ähnlicher Form wie eine Telefongebührenkarte oder ggf. auch gegen Entrichtung eines festen Beitrags für einen vorgegebenen Zeitraum erworben werden kann, vermittelt die Benutzungsberechtigung für das System. Die Empfangsbereitschaft kann am Zusatzgerät 1 mittels einer Empfangsanzeige 6 optisch dem Benutzer angezeigt werden. Empfangene Verkehrsinformationen werden von der Prozessoreinheit 4 in einen seriellen Datenstrom umgewandelt, der über das Datenkabel 8 an das Rechnersystem 9 übermittelt wird. Das im Rechnersystem installierte Software-Programm, das dem Benutzer von dem Diensteanbieter z.B. zusammen mit dem Kauf des Zusatzgerätes 1 auf einer Diskette oder einer CD-ROM zur Verfügung gestellt wurde, ist in der Lage, auf dem Bildschirmgerät 12 den übermittelten Datenstrom als visuelle Verkehrsinformation in Form einer Straßenkarte oder eines Straßenkartenausschnitts dem Benutzer darzubieten. Die auf dem Bildschirmgerät 12 dargestellten Straßenzüge sind in der Figur mit dem Bezugszeichen 10 versehen worden. Informationen zur aktuellen Verkehrssituation werden nun von dem Software-Programm ortsgerecht entlang dem Verlauf der Straßenzüge optisch dargestellt. Diese Darstellung erfolgt vorzugsweise mittels leicht erfaßbarer Symbole und/oder verbaler Bezeichnungen und/oder von Zahlenangaben, wie dies exemplarisch an der mit dem Bezugszeichen 11 versehenen Stelle der Fall ist.In the figure is a corresponding computer system 9 designed as a PC with a Display device 12 shown. The computer system 9 is connected to a data cable 8 Additional device 1 connected.

In dieser Hinsicht sind verschiedene Möglichkeiten gegeben. Beispielsweise können Teilgebiete mit fest vorgegebener Größe hinterlegt sein, die durch einen Mausklick ausgewählt und in vergrößerter Form dargestellt werden. Es kann aber auch vorgesehen sein, daß mit Hilfe der Maus ein Rechteck manuell aufgezogen wird, das die Lage und Größe des gewünschten Kartenausschnitts repräsentiert. Ebenso ist es möglich, durch Tastatureingaben beispielsweise die Bezeichnungen von interessierenden Autobahnen oder Autobahnabschnitten oder geografische Gebiete (z.B. Bundesland oder Stadtgebiet oder Landkreis) einzugeben. Wenn keine Auswahl eines engeren Landkartenausschnitts erfolgt, werden die Verkehrsinformationen in einer Gesamtdarstellung des Verkehrsgebiets dargeboten. In diesem Fall kann es zweckmäßig sein, zur Verbesserung der Übersichtlichkeit lediglich Verkehrsinformationen anzuzeigen, die von größerer Bedeutung sind. Hierzu können entsprechende Klassifikationen von Verkehrsmeldungen in der auf dem Rechner installierten Software enthalten sein, so daß die tatsächlich vorliegenden Verkehrsmeldungen entsprechend selektiert werden können. Die umfangreichen Informationen zur grafischen Form der digitalisierten Straßenkarte sind ebenfalls Bestandteil der auf dem Rechnersystem 12 installierten Software.The software program provided to the user preferably includes a zoom function with which the user can choose from the full range of the traffic area displayed traffic information those information can choose which are related to a sub-area of interest. In this There are various options with regard to this. For example, partial areas with a predefined size, selected by a click of the mouse and are shown in enlarged form. But it can also be provided that with the help of the mouse, a rectangle is drawn up manually, which shows the location and size of the desired map section. It is also possible to go through Keyboard entries, for example, the names of highways of interest or motorway sections or geographical areas (e.g. federal state or City area or district). If no selection of a narrow one Map section is made, the traffic information in one Overall presentation of the traffic area. In this case it can be useful, only to improve clarity Display traffic information that is more important. You can do this corresponding classifications of traffic reports in the on the computer installed software, so that the actual available Traffic announcements can be selected accordingly.
