Beschreibungdescription
Die Erfindung betrifft ein Verfahren zur Übertragung von Verkehrsinformationen betreffend ein Straßenverkehrsnetz von einer Verkehrsinformationszentrale an mindestens ein Endgerät und Vorrichtungen zur Durchführung des Verfahrens.The invention relates to a method for transmitting traffic information relating to a road traffic network from a traffic information center to at least one terminal and devices for carrying out the method.
Verkehrsinformationen werden von einer Verkehrsinformationszentrale an ein Endgerät in der Regel drahtlos (per Funk) übertragen. Wegen der relativ geringen und teuren Funk-Übertragungskapazitäten ist eine komprimierte Kodierung erforderlich.Traffic information is usually transmitted wirelessly (by radio) from a traffic information center to a terminal. Because of the relatively small and expensive radio transmission capacities, compressed coding is required.
Dem Fachmann ist bekannt, RDS-Übertragungsverfahren (RDS-TMC) für Verkehrsinformationen zu verwenden. RDS (radio data System) betrifft die Übertragung von digitalen alphanumerischen Informationen über einen Radio-Kanal ähnlich der Übertragung von Videotext-Informationen über Femsehkanäle. Bei derIt is known to the person skilled in the art to use RDS transmission methods (RDS-TMC) for traffic information. RDS (radio data system) relates to the transmission of digital alphanumeric information via a radio channel similar to the transmission of teletext information via television channels. In the
Übertragung von Verkehrsinformationen über RDS-TMC werden in der Regel festgelegte Segmente aller relevanten Straßen bestimmten zu übertragenden Codes zuordnende Tabellen in der Verkehrszentrale und im Endgerät verwendet. Dies hat den Vorteil einer bezüglich eines Straßenabschnittes sehr kurzen Übertragungssequenz, jedoch die Nachteile relativ teurer, auf die Implementierung obiger Tabellen angewiesener Endgeräte und auf die Tabellen-Codes der Segmente festgelegter Übertragungen.Transmission of traffic information via RDS-TMC, as a rule, defined segments of all relevant roads, tables associated with specific codes to be transmitted, are used in the traffic center and in the terminal. This has the advantage of a transmission sequence which is very short with respect to a road section, but the disadvantages of relatively expensive terminals which rely on the implementation of the above tables and on the table codes of the segments of transmissions.
Aus der DE 197 50 786 A1 derselben Anmelderin ist hingegen bekannt, Verkehrsinformationen mit den geographischen Ortskoordinaten von in zu übertragenden Verkehrsinformationen angegebenen Segmenten durch in vorgegebener Weise komprimiert angegebene geografischen Ortskoordinatendaten sowie durch Straßen, beispielsweise durch textuelle Angaben ("A8") repräsentierende Ortszusatzsdaten, zu übertragen. Dieses Übertragungsverfahren hat den Vorteil, auch auf sehr kostengünstigen Verkehrsinformations-Endgeräten anwendbar zu sein. Bei geeignet kodierter Übertragung ist auch eine Übertragung als Kurznachricht an übliche Mobilfunkendgeräte zur dortigen Anzeige in einem ausreichend großen Textfeld vorstellbar. Nachteilig ist hier die durch die übertragenen Ortszusatzdaten im Vergleich zur Referenzierung von Straßenabschnitten gemäß obigem RDS-TMC-Verfahren relativ große zu übertragende Datenmenge.From DE 197 50 786 A1 by the same applicant, however, it is known to add traffic information with the geographic location coordinates of segments specified in traffic information to be transmitted by means of geographic location coordinate data specified in a predetermined manner, as well as additional location data representing streets, for example by textual information (“A8”) transfer. This transmission method has the advantage that it can also be used on very inexpensive traffic information terminals. at A suitably coded transmission is also conceivable as a short message to conventional mobile terminals for display there in a sufficiently large text field. The disadvantage here is the relatively large amount of data to be transmitted as a result of the additional location data transmitted in comparison with the referencing of road sections according to the above RDS-TMC method.
Aufgabe der vorliegenden Erfindung ist die Schaffung eines Übertragungsverfahrens für Verkehrsinformationen, welches sowohl eine komprimierte Übertragung (mit geringer zu übertragener Informationsmenge wie beim obigen RDS-TMC-Verfahren) als auch eine Übermittlung von Verkehrsinformationen in durch einfache Endgeräte dekodierbarer Form erlaubt. Die Aufgabe wird durch die Gegenstände der unabhängigen Ansprüche gelöst.The object of the present invention is to provide a transmission method for traffic information which allows both a compressed transmission (with a smaller amount of information to be transmitted than in the above RDS-TMC method) and a transmission of traffic information in a form decodable by simple terminals. The object is solved by the subject matter of the independent claims.

The terminal can determine the type of coding of the transmitted traffic information received (i.e. whether it is by location coordinate data or by the
Identität von Segmenten repräsentierende Segmentidentitätendaten handelt) aufgrund der in den Verkehrsinformationen übertragenen Auswahlinformationen bestimmen. Die Auswahlinformationen werden zweckmäßig in Form eines Flags in den übertragenen Verkehrsinformationen angegeben.

The selection information is expediently specified in the form of a flag in the transmitted traffic information.

Die Kodiereinrichtung 9 der Zentrale 1 kodiert zu übertragende Verkehrsinformationen unter Verwendung der im Speicher 12 gespeicherten Segmentetabelle oder der imThe coding device 9 of the control center 1 codes traffic information to be transmitted using the segment table stored in the memory 12 or in the
Speicher 13 gespeicherten GeoCode-Tabelle.Memory 13 stored GeoCode table.
Eine im Speicher 12 gespeicherte Tabelle ist beispielhaft in Figur 3 dargestellt. In diesem Beispiel repräsentiert ein Segment (mit der Nummer 1 , 2, 3 ..., 1 1 , 12 usw.) jeweils ein Segment eines Straßenverkehrsnetzes. Ein Segment kann eine Straße sein. Ein Segment kann auch ein Straßenabschnitt sein. Auch ist es möglich, für eine oder mehrere Fahrbahnen mit gemeinsamer oder unterschiedlicher Fahrtrichtung einer Straße oder eines Straßenabschnittes ein Segment zu definieren. Ferner kann in einem Speicher mit Segmenten eine vom Endgerät auszugebende (7) Textinformation gespeichert sein. In Figur 3 ist als Beispiel zu jedem Segment eine vom Endgerät 6 auszugebende (7) Textinformation angegeben, wie "A9 Richtung Norden München bis Nürnberg" für das Segment 12.A table stored in the memory 12 is shown by way of example in FIG. 3. In this example, a segment (with the numbers 1, 2, 3 ..., 1 1, 12, etc.) represents a segment of a road network. A segment can be a street. A segment can also be a section of a street. It is also possible to define a segment for one or more lanes with a common or different direction of travel of a road or a road section. Furthermore, (7) text information to be output by the terminal can be stored in a memory with segments. In FIG. 3, text (7) to be output by the terminal 6 is given as an example for each segment, such as "A9 towards north Munich to Nuremberg" for the segment 12.
In Figur 3 sind in den Spalten 30 und 31 jeweils Ortskoordinatendaten (= GeoCodes) angegeben, welche Koordinaten repräsentieren gemäß Spalten 32, 33. "12345678" repräsentiert z.B. die Koordinaten 12°34'WL56°78'NB. Ein Segment 12 kann auch zu mehreren Ortskoordinatendaten (12345678, 12345679) gehören. Spalte 34 zeigt Segmentidentitätendaten, die wahlweise ebenfalls übertragen werden können.In Figure 3, columns 30 and 31 each show location coordinate data (= GeoCodes) which represent coordinates according to columns 32, 33. "12345678" represents e.g. the coordinates 12 ° 34'WL56 ° 78'NB. A segment 12 can also belong to a plurality of location coordinate data (12345678, 12345679). Column 34 shows segment identity data, which can optionally also be transmitted.
Mit einer Tabelle kodiert übertragene Informationen 4 (in Figur 1 ), nämlich "1 - 3 - 0 - Ende" umfassen eine Auswahlinformation (erste "1 "), welche angibt, daß die Verkehrsinformationen Segmente ohne Angabe ihres Ortes durch ihre Identität repräsentieren, eine Angabe mindestens einer in der Verkehrsinformation repräsentierten Segmentes (zweite "1" in 4), die (bei Routenhinweisen evtl. wegfallende) Information über die Durchschnittsgeschwindigkeit in diesen Segmenten ("0" für Geschwindigkeit 0 km/h oder Stau) in beliebiger, definierter Quantisierung und ein das Ende der Segmentinformation angebendes Ende-Zeichen ("Ende"). Die Verkehrsinformationen 3 repräsentieren hingegen den Ort von Segmenten in den Verkehrsinformationen durch übertragene Ortskoordinaten-Daten (hier mit Ortszusatzdaten). Die übertragenen Verkehrsinformationen 3 beginnen ebenfalls mit Auswahlinformationen, welche durch die führende "0" der Dekodiereinrichtung 15 des Endgerätes 6 darstellen, daß im folgenden eine Bezeichnung des Ortes vonInformation 4 coded with a table (in FIG. 1), namely “1-3-0 - end”, comprises selection information (first “1”), which indicates that the traffic information represents segments without specifying their location by their identity, one Indication of at least one segment represented in the traffic information (second "1" in 4), the information (possibly omitted from route information) about the average speed in these segments ("0" for speed 0 km / h or traffic jam) in any defined quantization and an end character ("end") indicating the end of the segment information. The traffic information 3, on the other hand, represents the location of segments in the traffic information by means of transmitted location coordinate data (here with additional location data). The transmitted traffic information 3 likewise begins with selection information which, by the leading "0" of the decoding device 15 of the terminal 6, represents in the following a description of the location of
Segmenten folgt. Die Auswahlinformationen können anstatt führend, wie dargestellt, auch am Ende der Sequenz oder in der Mitte übertragen werden. Die den Auswahlinformationen folgenden Ortskoordinatendaten "1 , 2, 3, 4, 5, 6, 7, 8" repräsentieren beispielsweise 12°34' westlicher Länge, 56°58' nördlicher Breite. Überdies sind Ortszusatzinformationen "A8, Abfahrt Pasing" angegeben, welche bei sehr einfachen Endgeräten 6 als Text ausgegeben (7) werden können, ohne vorherige Überarbeitung oder Aufbereitung mit Tabellen sowie kodierte ("4711") und/oder unkodierte ("Glatteis") Informationen zu Zuständen der betroffenen Segmente. Kodierte Informationen, wie "471 1 " können beispielsweise eine Geschwindigkeit von 47, 1 1 km/h in den betroffenen Segmenten repräsentieren. Unkodierte Informationen, wie "Stau" oder "Glatteis" können auch in einfachen Endgeräten unmittelbar ausgegeben werden. Verkehrsinformationen 3 mit Orte von Segmenten repräsentierenden Ortskoordinatendaten können von der Kodiereinrichtung 15 mittels einer im Speicher 17 gespeicherten (zur Tabelle im Speicher 13 identischen GeoCode- Tabelle (beispielsweise gemäß Figur 5) dekodiert werden. Aufwendigere Endgeräte mit einer derartigen GeoCode-Tabelle (= Ortskoordinatentabelle) können somit die Verkehrsinformationen 3 sehr detailliert Einzelsegmenten zuordnen und hochspezifizierte Ausgaben 7 für den Endgerätnutzer ggf. unter Verwendung einer digitalen Karte etc. erarbeiten. Einfachere Endgeräte 15 können die übertragenen Ortskoordinatendaten und/oder die übertragenen Textinformationen ohne Bearbeitung ausgeben.Segments follows. The selection information can be transmitted at the end of the sequence or in the middle instead of leading, as shown. The location coordinate data "1, 2, 3, 4, 5, 6, 7, 8" following the selection information represent, for example, 12 ° 34 'west longitude, 56 ° 58' north latitude. In addition, additional location information "A8, exit Pasing" is given, which can be output as text (7) in the case of very simple terminal devices 6, without prior revision or preparation with tables, and coded ("4711") and / or uncoded ("black ice") information on the states of the affected segments. Coded information such as "471 1" can represent, for example, a speed of 47.1 1 km / h in the segments concerned. Uncoded information such as "traffic jam" or "black ice" can also be output directly in simple end devices. Traffic information 3 with location coordinate data representing locations of segments can be decoded by the coding device 15 by means of a GeoCode table stored in the memory 17 (identical to the table in the memory 13 (for example according to FIG. 5)). More complex terminals with such a GeoCode table (= location coordinate table) can thus allocate the traffic information 3 in a very detailed manner to individual segments and develop highly specified outputs 7 for the terminal user, possibly using a digital map, etc. Simpler terminal devices 15 can output the transmitted location coordinate data and / or the transmitted text information without processing.
Die Auswahl der Kodierung (also durch Ortskoordinaten oder Segment-Identitäten) in der Zentrale kann z.B. durch Abfrage einer manuellen Eingabe eines Operators oder z.B. bei einer Anfrage eines Endgerätes bei der Zentrale nach Verkehrsinformationen durch eine Angabe in der Anfrage erfolgen.The selection of the coding (i.e. by location coordinates or segment identities) in the control center can e.g. by querying a manual entry of an operator or e.g. when requesting a terminal from the head office for traffic information by specifying in the request.
Eine Kreuzreferenztabelle (im Speicher 14 in Figur 1 ) gemäß Figur 3 erlaubt den endgerätseitigen Rückschluß von empfangenen Segmentidentitäten ohne unmitelbare (also ohne Tabelle als Ort dekodierbare) Ortsangabe zu Orten, z.B. vom Segment 12 auf 12°34' WB; 56°78' NL etc.A cross-reference table (in the memory 14 in FIG. 1) according to FIG. 3 allows the terminal-side inference of received segment identities without being able to be identified (ie without table as a location that can be decoded) location information on locations, eg from segment 12 to 12 ° 34 'WB; 56 ° 78 'NL etc.
Figur 2 zeigt ein Beispiel der Kodierung eines Straßenverkehrsnetzes durch Segmente. Die Segmente 1 bis 11 enden jeweils an Kreuzungen, Abfahrten,Figure 2 shows an example of the coding of a road network by segments. The segments 1 to 11 end at intersections, exits,
Abzweigungen etc. Abzweigungen zu Straßen niedrigerer Klassen (beispielsweise von einer Autobahn auf eine Landstraße wie zwischen dem Segment 7 und 8) sind hier nur soweit relevant (also in Form der abzweigenden Autobahn) dargestellt. Anstatt wie hier ein Segment kann auch mehr als ein Segment für die unterschiedlichen Richtungen und/oder Fahrbahnen eines Straßenabschnittes verwendet werden.Branches etc. Branches to streets of lower classes (for example from a freeway to a country road as between segments 7 and 8) are only shown as far as relevant (i.e. in the form of the branching freeway). Instead of a segment as here, more than one segment can also be used for the different directions and / or lanes of a road section.
Die Erfindung kann in einer Verkehrsinformationszentrale und im Endgerät als Programm oder als elektronische Schaltung realisiert werden. Sie ist jedoch nicht auf die Realisierung als Programm beschränkt. The invention can be implemented in a traffic information center and in the terminal as a program or as an electronic circuit. However, it is not limited to implementation as a program.
