Dies ermöglicht eine universell einstellbare, effiziente Übertragung von Informationen. Insbesondere kann durch eine Initialisierungssequenz festgelegt werden, welcher Art die nachfolgenden Informationen sind. So kann eine Initialisierungssequenz festlegen, ob Textauswahldaten zur endgerätseitigen Auswahl eines standardisierten Textes aus einer Texttabelle im Endgerät mit mehreren standardisierten Texten und/oder ein beliebiger, nicht vordefinierter Text (Freitext) und/oder Graphikauswahldaten zur endgerätseitigen Auswahl eines Graphiksymbols zur Anzeige aus einer Graphikdatei mit mehreren Graphiksymbolen umfassen.According to one embodiment of the invention, the speed data is of a type the initialization sequence (header) defining the data following it.

Figur 1 zeigt eine Straße 1, auf welcher ein Fahrzeug 2 sich in Richtung des Pfeiles 3 fortbewegt. Von der Straße 1 biegen weitere Zufahrten und Abfahrten 4, 5, 6 ab. Ein Endgerät im Fahrzeug 2 erhält von einer Verkehrszentrale 7 per Funk, hier Mobilfunk, Verkehrsinformationen 8 zum Verkehrszustand einer in Fahrtrichtung 3 vor dem Fahrzeug liegenden Strecke. Dabei ist die Strecke hier in der Zentrale und im Endgerät in mehrere Segmente S1, S2, S3 unterteilt, zu welchen jeweils Verkehrsinformationen an das Endgerät übertragen werden. Hier umfassen die Verkehrsinformationen insbesondere Geschwindigkeiten des Verkehrs in den Segmenten S1 bis S3 repräsentierende Geschwindigkeitsdaten, also Geschindigkeiten oder Reisezeiten repräsentierende Informationen. Dabei werden die Geschwindigkeiten quantifiziert zu je einem Streckensegment übermittelt. Beispielsweise wird zum Streckensegment S1 eine mittlere Geschwindigkeit der dort fahrenden Fahrzeuge von 30 km/h zum Streckensegment S2 eine mittlere Geschwindigkeit von 40 km/h und zum Streckensegment S3 eine mittlere Geschwindigkeite von 100 km/h übermittelt. Die Übermittlung von Geschwindigkeiten bzw. Reisezeiten zu einzelnen Segmenten optimiert die Information des Benutzers des Endgerätes im Fahrzeug 2 und die dortige Berechnung von Routen u.U. einschließlich Reisezeiten oder dgl. Die Zentrale 7 kann Informationen, aus welchen sie an das Endgerät zu übermittelnde Verkehrsinformationen erstellt, aus beliebigen Quellen erhalten, insbesondere von Verkehrsrechnerzentralen, Landesmeldestellen und/oder stationären Detektoren und/oder im Verkehr mitfahrenden Fahrzeugen.FIG. 1 shows a street 1 on which a vehicle 2 is moving in the direction of the arrow 3 moved. Further entrances and exits 4, 5, 6 turn off road 1. A Terminal in vehicle 2 receives from a traffic control center 7 by radio, here mobile radio, Traffic information 8 on the traffic condition in the direction of travel 3 before Vehicle lying route. The route is here at the headquarters and in Terminal divided into several segments S1, S2, S3, each of which Traffic information is transmitted to the terminal. Here include the Traffic information especially speeds of traffic in the Speed data representing segments S1 to S3, that is Information representing speed or travel times.

Deshalb werden die nachfolgenden Daten zu Streckensegmenten im Endgerät in einer Tabelle nachgesehen und die in der Tabelle jeweils zugeordneten Geschwindigkeiten für das jeweilige Streckensegment angenommen und dem Benutzer des Endgerätes dargestellt. Alternativ kann ein Navigator die Daten entsprechend der Initialisierungssequenz interpretieren und bei der Routenberechnung berücksichtigen.Here the header, i.e. the initialization sequence, contains the sequence 000 what means that coded numeric data sequences follow. That's why they are following data on route segments in the terminal in a table looked up and the speeds assigned in the table for the respective route segment accepted and the user of the terminal shown. Alternatively, a navigator can use the data according to the initialization sequence interpret and take into account when calculating the route.

Zum Streckensegment 1 werden hier im Abschnitt 9 das Streckensegment 1 definierende Daten sowie Daten zur Geschwindigkeit im Streckensegment 1 definiert. Die Informationen umfassen auch die Richtung, in der ein Streckensegment von einer Verkehrsstörung betroffen ist. Die Geschwindigkeit repräsentierende Daten können beispielsweise fünfstellige binäre Ziffern sein, welche eine Quantifizierung in 32 Stufen ermöglichen, also 32 Geschwindigkeiten und/oder andere Daten, wie Nebel, Glatteis, Smog, Falschfahrer etc.The section segment 1 becomes section segment 1 here in section 9 defining data and data on speed in route segment 1 are defined.

Am Ende der übertragenen Informationen ist eine Kontrollsequenz, also eine Prüfsumme (checksum), übertragen, welche zur Detektion und evtl. Korrektur von Übertragungsfehlern zwischen der Zentrale 7 und dem Fahrzeug 2 dient. The same applies to the information blocks 10, 11 for the others Route segments. At the end of the transmitted information is one Control sequence, i.e. a checksum, transmitted, which for detection and possibly correction of transmission errors between the control center 7 and the Vehicle 2 is used.

Die Übertragung von der Verkehrszentrale eines Informationsanbieters an ein Endgerät kann zielgerichtet (point-to-point), z.B. durch GSM-SMS, oder ungerichtet (broadcast), z.B. durch DAB, erfolgen.The transmission from the traffic center of an information provider to a Terminal can be targeted (point-to-point), e.g. by GSM-SMS, or non-directional (broadcast), e.g. by DAB.
