Definitions
- the invention relates to a method for transmitting a position of a traffic information, in particular a traffic jam, on a traffic route in digitally coded messages, being used for coding and decoding the messages sender and receiver side location databases and an approximate position of the traffic information by referencing the traffic route and at least one location located on the traffic route contained in the location databases is coded.
- the transmission of digitally encoded traffic messages is based on locations that are listed both in the transmitter and receiver side in the context of traffic routes in location databases. These places are traffic-related points, such as descents and intersections, which are referenced among each other in the form of predecessor and successor and on the associated road segment, the associated road segment is in turn part of a road.
- WO 99-A-48073 A discloses a vehicle navigation system with a traffic receiver for receiving traffic information, which is characterized by the specification of a location, in particular starting or end location, and a traffic event. It is proposed here not only to regard the route section covered by the traffic report as being affected by the traffic incident, but also all the route sections (including those which are not on the traffic-affected road) within a predetermined radius around the coded transmitted traffic report.
- the basic idea of document 1 is to specify a method that allows a widespread bypassing of traffic jams. It is assumed that the transmitted segment is small compared to the perturbation, and the desired effect is achieved by extending the perturbation to additional surrounding segments.
- EP-A-0 902 406 discloses the possibility to combine sections of a traffic route network into partial routes and to transmit information relating to a particular position on such a partial route such as travel times, environmental data, temperatures, etc. such that only a "one-dimensional path parameter", such as the distance from the beginning of the partial route, to indicate the exact location.
- the essential content of the method specified in document 2 is the re-coding of a road network based on named edges in order to enable a reduction of the data to be transmitted.
- the object of the present invention is to more accurately transmit a position, in particular the position of a traffic incident, on a traffic route.
- This object is achieved with the method according to the invention in that in addition to the location of the distance share between the position and the location is transmitted. This makes it possible, inter alia receiver side, to use by comparing the transmitted position with non-coded intersections roads to bypass the disorder that are not recognized in the known transmission to ALERT-C by means of location code of the primary location and the extent of the disturbance.
- the method according to the invention is not only applicable with RDS / TMC, but can be used wherever messages are transmitted in a similar manner on the basis of coded location databases, for example in the GSM / TMC.
- the link is related to the link between the encoded location and a remote from the coded location on the road away. Since the transmission capacity for the link share is limited, this embodiment may result in potentially unsatisfactory accuracy if the scale involves many road segments.
- the distance share is related to the distance between the encoded location and an encoded location immediately adjacent in the database on the same traffic route existing place.
- an embodiment of the invention is particularly favorable, which consists in the coding of the track share in the label 15 when coding according to the ALERT-C protocol.
- An equally favorable possibility is that when coding according to the ALERT-C protocol, the coding of the track share in the label 12 is done.
- the label 15 provides a 5-bit data field, with which an accuracy of 5% can be achieved at the position, which is quite sufficient for the fulfillment of the object according to the invention.
- a 16-bit value may be provided for the link, resulting in a correspondingly higher accuracy.
- the traffic information may be related to a punctiform location, for example a road blockage, a danger location or status information such as the average speed of the vehicles passing the punctiform location.
- the traffic information may also refer to an extended event or object, such as a traffic jam (congestion).
- TMC receivers can also work with databases without distance information.
- another embodiment enables the coding of positions transmitted by the method according to the invention in that, in the absence of distance information in the location database of the receiver, the distance information is taken from a digital map assigned to the receiver.
- a fault S is coded by specifying a primary location L1 and the extent in the form of the number of road segments up to a secondary location L2, between which the disturbance S is located in the figures is highlighted by the filling of the road R performing double line. This is also done when - as in the illustrated embodiments - the disturbance S between the points X (start point) and Y (end point) does not extend over the entire distance between L1 and L2.
- the disturbance length L can be coded with an accuracy of about 10%.
- the position of the point X is transmitted by the percentage percentage D of the distance between L1 and L2. Since A is either stored in the recipient's location database or can be taken from a digital map, D can be calculated from the transmitted size P.
- Fig. 2 is located between the two locations L1 and L2 another location L3, which is also listed in the location database.
- a TMC message is then transmitted stating that there is an error of magnitude 2 in front of the location L1, which without further indication can mean that the entire distance between L1 and L2 affected by the disorder.
- the link D is not related to the distance between L1 and L2 but to the distance A 'between L1 and L3, so that the position X is transmitted with greater accuracy.
- P or P ' is then transmitted as a data telegram with the identifier label 15 to the receiver. If the same coding table is used as in qualifier 3, the result is a 5-bit value of 6, which is entered in the data field following label 15.
- the decoding in the receiver takes place, for example, via a look-up table.
- the receiver can calculate the position of the point X on the one hand, and the position of the point Y on the other hand, using the also transmitted disturbance length L. As shown in Fig. 3, in conjunction with a navigation system having a digital map, this information can be used to bring the driver close to the end of the jam and return to the original route earlier after bypassing the jam.
- Fig. 3 shows the same route as Fig. 2 with the locations L1, L2 and L3 and the disturbance S between the points X and Y.
- other places 01 to 07 are shown, of which at least the places 01 and 03 in the for Coding and decoding used place databases are not registered.
- the driver on the places 01, 02 and 03 that is over a shorter detour route than without the application of the method, conducted, where he on the locations 04, 05, 06 and 07 would have to be performed.
- the label 12 can be used.
- ALERT-C already has a 16-bit field for the value. This allows the position to be transmitted with a higher resolution (eg in 100% / 65536) if required.
- the method is also used with other than percentage information of the track share, i. as absolute or relative distance, for example in units of length or with label 2 or with label 5, quantifier 9, or by introducing a new table (corresponding to use with quantifier, see ENV12313-2).
Description
Die Erfindung betrifft ein Verfahren zur Übertragung einer Position einer Verkehrsinformation, insbesondere einer Verkehrsstörung, auf einem Verkehrsweg in digital codierten Meldungen, wobei zur Codierung und Decodierung der Meldungen sender- und empfängerseitig Ortsdatenbanken verwendet werden und eine ungefähre Position der Verkehrsinformation durch Referenzierung auf den Verkehrsweg und mindestens einen in den Ortsdatenbanken enthaltenen auf dem Verkehrsweg befindlichen Ort codiert wird.The invention relates to a method for transmitting a position of a traffic information, in particular a traffic jam, on a traffic route in digitally coded messages, being used for coding and decoding the messages sender and receiver side location databases and an approximate position of the traffic information by referencing the traffic route and at least one location located on the traffic route contained in the location databases is coded.
Die Übertragung von digital codierten Verkehrsmeldungen, insbesondere von nach dem ALERT-C-Protokoll codierten und decodierten TMC-Meldungen, ist auf Orte gestützt, die sowohl sender- als auch empfängerseitig im Zusammenhang mit Verkehrswegen in Ortsdatenbanken aufgeführt sind. Diese Orte sind verkehrsrelevante Punkte, wie beispielsweise Abfahrten und Kreuzungen, die untereinander in Form von Vorgänger und Nachfolger und auf das zugehörige Straßensegment referenziert sind, wobei das zugehörige Straßensegment wiederum Teil einer Straße ist.The transmission of digitally encoded traffic messages, in particular messages encoded and decoded according to the ALERT-C protocol, is based on locations that are listed both in the transmitter and receiver side in the context of traffic routes in location databases. These places are traffic-related points, such as descents and intersections, which are referenced among each other in the form of predecessor and successor and on the associated road segment, the associated road segment is in turn part of a road.
Durch die Beschränkung auf diese verkehrsrelevanten Punkte wird zwar der Umfang der Ortsliste minimiert, gleichzeitig ist aber eine vollständige Beschreibung des Verkehrswegenetzes, insbesondere Straßennetzes, unmöglich. Die Beschreibung der Autobahnen ist zwar noch relativ vollständig, für die untergeordneten Straßenklassen liegen jedoch zwischen zwei codierten Orten ein oder mehrere nicht codierte Knotenpunkte. Da in TMC-Meldungen nur jeweils ein Ortscode übertragen wird (primärer Ort), auf den sich die Störung bezieht, und ein Ausmaß, das angibt, wieviele codierte Orte auf einer Strecke von der Störung betroffen sind, wird sowohl der Anfang als auch das Ende der Störung nur in Form von codierten Orten (primärer und sekundärer Ort) übertragen. Da die Anzahl der codierten Orte auf den untergeordneten Straßenklassen gering ist, ist hier die Präzision der Ortsangabe unbefriedigend, da zwischen dem primären und dem sekundären Ort in der Regel mehrere Kreuzungen mit anderen Straßen liegen, die von einem Navigationssystem zur Umfahrung der Störung genutzt werden könnten.Although the scope of the location list is minimized by restricting to these traffic-relevant points, at the same time a complete description of the traffic route network, in particular the road network, is impossible. Although the description of the motorways is still relatively complete, for the subordinate road classes there are one or more non-coded nodes between two coded locations. Since TMC messages transmit only one location code at a time (primary location) to which the fault relates, and an extent that indicates how many encoded locations on a route are affected by the interference, both the beginning and the end will be transmitted the disturbance transmitted only in the form of coded locations (primary and secondary location). Since the number of coded locations on the subordinate road classes is low, the precision of the location is unsatisfactory here, since between the primary and the secondary location usually more intersections with other roads, which could be used by a navigation system to avoid the disturbance ,
WO 99-A-48073 A offenbart ein Fahrzeugnavigationssystem mit einem Verkehrsfunkempfänger zum Empfang von Verkehrsinformationen, die sich durch die Angabe eines Ortes, insbesondere Anfangs- bzw. Endortes, und eines Verkehrsereignisses auszeichnen. Es wird hier vorgeschlagen, nicht nur den durch die Verkehrsmeldung abgedeckten Streckenabschnitt als von der Verkehrsstörung betroffen anzusehen, sondern darüber hinaus alle Streckenabschnitte (auch solche, die nicht auf der gemäß Verkehrsmeldung betroffenen Straße liegen) in einem vorgegebenen Umkreis um die codiert übertragene Verkehrsmeldung. Der Grundgedanke der Druckschrift 1 ist es dabei, ein Verfahren anzugeben, dass eine weitläufige Umfahrung von Verkehrsstörungen erlaubt. Dabei wird angenommen, dass das übermittelte Segment klein gegenüber der Störung ist, und man durch Ausdehnung der Störung auf zusätzliche das betroffene umgebende Segmente die gewünschte Wirkung erzielt.WO 99-A-48073 A discloses a vehicle navigation system with a traffic receiver for receiving traffic information, which is characterized by the specification of a location, in particular starting or end location, and a traffic event. It is proposed here not only to regard the route section covered by the traffic report as being affected by the traffic incident, but also all the route sections (including those which are not on the traffic-affected road) within a predetermined radius around the coded transmitted traffic report. The basic idea of document 1 is to specify a method that allows a widespread bypassing of traffic jams. It is assumed that the transmitted segment is small compared to the perturbation, and the desired effect is achieved by extending the perturbation to additional surrounding segments.
EP-A-0 902 406 offenbart die Möglichkeit, Streckenabschnitte eines Verkehrswegenetzes zu Teilwegen zusammenzufassen und eine bestimmte Position auf einem solchen Teilweg betreffende Informationen wie Reisezeiten, Umweltdaten, Temperaturen etc. so zu übertragen, dass lediglich ein "eindimensionaler Bahnparameter", wie der Abstand vom Anfang des Teilwegs, zur Bezeichnung des genauen Orts angegeben wird. Wesentlicher Inhalt des in Druckschrift 2 angegebenen Verfahrens ist die Re-Codierung eines Wegenetzes anhand von benannten Kanten, um eine Reduzierung der zu übertragenen Daten zu ermöglichen.EP-A-0 902 406 discloses the possibility to combine sections of a traffic route network into partial routes and to transmit information relating to a particular position on such a partial route such as travel times, environmental data, temperatures, etc. such that only a "one-dimensional path parameter", such as the distance from the beginning of the partial route, to indicate the exact location. The essential content of the method specified in document 2 is the re-coding of a road network based on named edges in order to enable a reduction of the data to be transmitted.
Aufgabe der vorliegenden Erfindung ist es, eine Position, insbesondere die Position einer Verkehrsstörung, auf einem Verkehrsweg genauer zu übertragen.The object of the present invention is to more accurately transmit a position, in particular the position of a traffic incident, on a traffic route.
Diese Aufgabe wird mit dem erfindungsgemäßen Verfahren dadurch gelöst, daß zusätzlich zu dem Ort der Streckenanteil zwischen der Position und dem Ort übertragen wird. Dadurch wird unter anderem empfängerseitig ermöglicht, durch den Vergleich der übertragenen Position mit nicht codierten Kreuzungen Straßen zur Umfahrung der Störung zu nutzen, die bei der bekannten Übertragung nach ALERT-C mittels Ortscode des primären Ortes und mittels Ausmaß der Störung nicht erkannt werden.This object is achieved with the method according to the invention in that in addition to the location of the distance share between the position and the location is transmitted. This makes it possible, inter alia receiver side, to use by comparing the transmitted position with non-coded intersections roads to bypass the disorder that are not recognized in the known transmission to ALERT-C by means of location code of the primary location and the extent of the disturbance.
Das erfindungsgemäße Verfahren ist nicht nur mit RDS/TMC anwendbar, sondern ist überall da verwendbar, wo auf Basis von codierten Ortsdatenbanken Meldungen in ähnlicher Weise übertragen werden, beispielsweise beim GSM/TMC.The method according to the invention is not only applicable with RDS / TMC, but can be used wherever messages are transmitted in a similar manner on the basis of coded location databases, for example in the GSM / TMC.
Gemäß einer Ausgestaltung der Erfindung ist vorgesehen, daß der Streckenanteil auf die Strecke zwischen dem codierten Ort und einem um das Ausmaß von dem codierten Ort entfernten auf den Verkehrsweg liegenden Ort bezogen wird. Da die Übertragungskapazität für den Streckenanteil begrenzt ist, ergibt sich bei dieser Ausgestaltung eine möglicherweise nicht befriedigende Genauigkeit, wenn das Ausmaß viele Straßensegmente umfaßt.According to one embodiment of the invention, it is provided that the link is related to the link between the encoded location and a remote from the coded location on the road away. Since the transmission capacity for the link share is limited, this embodiment may result in potentially unsatisfactory accuracy if the scale involves many road segments.
Zur Behebung dieses Nachteils ist bei einer anderen Ausgestaltung des erfindungsgemäßen Verfahrens vorgesehen, daß der Streckenanteil auf die Strecke zwischen dem codierten Ort und einem dem codierten Ort unmittelbar benachbarten in der Datenbank auf demselben Verkehrsweg vorhandenen Ort bezogen ist.To remedy this disadvantage, it is provided in another embodiment of the method according to the invention that the distance share is related to the distance between the encoded location and an encoded location immediately adjacent in the database on the same traffic route existing place.
Für zusätzliche Zahlenangaben, wie sie auch der Streckenanteil darstellt, gibt es in einer TMC-Meldung nach ALERT-C verschiedene Möglichkeiten. Insbesondere bezüglich der Kompatibilität mit bestehenden Sendern und Empfängern ist eine Ausgestaltung der Erfindung besonders günstig, die darin besteht, daß bei einer Codierung nach dem ALERT-C-Protokoll die Codierung des Streckenanteils im Label 15 erfolgt. Eine ebenfalls günstige Möglichkeit besteht darin, daß bei einer Codierung nach dem ALERT-C-Protokoll die Codierung des Streckenanteils im Label 12 erfolgt.For additional figures, as it also represents the track share, there are various possibilities in a TMC message according to ALERT-C. In particular with regard to the compatibility with existing transmitters and receivers, an embodiment of the invention is particularly favorable, which consists in the coding of the track share in the label 15 when coding according to the ALERT-C protocol. An equally favorable possibility is that when coding according to the ALERT-C protocol, the coding of the track share in the label 12 is done.
Das Label 15 stellt ein 5-Bit-Datenfeld zur Verfügung, womit bei der Position eine Genauigkeit von 5% erreicht werden kann, was für die Erfüllung der erfindungsgemäßen Aufgabe durchaus ausreichend ist. Bei der Verwendung des Labels 12 kann ein 16-Bit-Wert für den Streckenanteil vorgesehen werden, was eine entsprechend höhere Genauigkeit ergibt.The label 15 provides a 5-bit data field, with which an accuracy of 5% can be achieved at the position, which is quite sufficient for the fulfillment of the object according to the invention. When using the label 12 For example, a 16-bit value may be provided for the link, resulting in a correspondingly higher accuracy.
Die Verkehrsinformation, deren Position mit dem erfindungsgemäßen Verfahren übertragen wird, kann auf einen punktförmigen Ort bezogen sein, beispielsweise eine Straßensperrung, eine Gefahrenstelle oder eine Statusinformation wie die Durchschnittsgeschwindigkeit der den punktförmigen Ort passierenden Fahrzeuge. Die Verkehrsinformation kann sich jedoch auch auf ein ausgedehntes Ereignis oder Objekt beziehen, wie beispielsweise eine Verkehrsstörung (Stau).The traffic information, the position of which is transmitted by the method according to the invention, may be related to a punctiform location, for example a road blockage, a danger location or status information such as the average speed of the vehicles passing the punctiform location. However, the traffic information may also refer to an extended event or object, such as a traffic jam (congestion).
Zur Übertragung des Endes einer Verkehrsstörung ist bei dem erfindungsgemäßen Verfahren vorgesehen, daß mit Hilfe des Streckenanteils die Position des Beginns (Ursache) einer Verkehrsstörung übertragen wird und daß das Ende einer Verkehrsstörung aus der über das Label 2 übertragenen Länge oder aus dem übertragenen Ereigniscode berechnet wird. Bei einem geeigneten Empfänger wird man beide Möglichkeiten vorsehen, da senderseitig nicht festgelegt ist, ob zur Übertragung der Länge einer Verkehrsstörung das Label 2 oder ein Ereigniscode benutzt wird.To transmit the end of a traffic jam is provided in the inventive method that the position of the beginning (cause) of a traffic jam is transmitted using the link share and that the end of a traffic jam is calculated from the length transmitted via the label 2 or from the transmitted event code , With a suitable receiver, both options will be provided, since it is not determined at the transmitter whether the label 2 or an event code is used to transmit the length of a traffic jam.
TMC-Empfänger können grundsätzlich auch mit Datenbanken ohne Entfernungsangaben arbeiten. Für diesen Fall ermöglicht eine andere Ausgestaltung die Codierung von nach dem erfindungsgemäßen Verfahren übertragenen Positionen dadurch, daß bei Nichtvorhandensein von Entfernungsangaben in der Ortsdatenbank des Empfängers die Entfernungsangaben aus einer dem Empfänger zugeordneten digitalen Karte entnommen werden.In principle, TMC receivers can also work with databases without distance information. In this case, another embodiment enables the coding of positions transmitted by the method according to the invention in that, in the absence of distance information in the location database of the receiver, the distance information is taken from a digital map assigned to the receiver.

Wie bereits erläutert, wird in einer TMC-Meldung nach ALERT-C eine Störung S durch Angabe eines primären Ortes L1 und des Ausmaßes in Form der Anzahl der Straßensegmente bis zu einem sekundären Ort L2 codiert, zwischen denen sich die Störung S befindet, die in den Figuren durch die Ausfüllung der die Straße R darstellende Doppellinie hervorgehoben ist. Dies erfolgt auch, wenn - wie bei den dargestellten Ausführungsbeispielen - sich die Störung S zwischen den Punkten X (Anfangspunkt) und Y (Endpunkt) nicht über die gesamte Entfernung zwischen L1 und L2 erstreckt. Zusätzlich kann nach ALERT-C über das Label 2 die Störungslänge L mit einer Genauigkeit von etwa 10% codiert werden.As already explained, in a TMC message according to ALERT-C a fault S is coded by specifying a primary location L1 and the extent in the form of the number of road segments up to a secondary location L2, between which the disturbance S is located in the figures is highlighted by the filling of the road R performing double line. This is also done when - as in the illustrated embodiments - the disturbance S between the points X (start point) and Y (end point) does not extend over the entire distance between L1 and L2. In addition, according to ALERT-C label 2, the disturbance length L can be coded with an accuracy of about 10%.
Bei dem Ausführungsbeispiel nach Fig. 1 wird die Position des Punktes X durch den prozentualen Streckenanteil D bezogen auf die Entfernung zwischen L1 und L2 übertragen. Da A entweder in der Ortsdatenbank des Empfängers abgelegt ist oder aus einer digitalen Karte entnommen werden kann, kann D aus der übertragenen Größe P berechnet werden.In the embodiment of Fig. 1, the position of the point X is transmitted by the percentage percentage D of the distance between L1 and L2. Since A is either stored in the recipient's location database or can be taken from a digital map, D can be calculated from the transmitted size P.
Senderseitig wird aus den bekannten Größen D und A die zu übertragende Größe zu P = D·100/A berechnet. Wenn beispielsweise der Abstand zwischen L 1 und L2 20 km beträgt und die Störungsursache 6 km vor dem primären Ort L1 liegt, ergibt sich ein zu übertragender Parameter von P=30%.On the transmitter side, the quantity to be transmitted is calculated from the known quantities D and A as P = D × 100 / A. For example, if the distance between L 1 and L 2 is 20 km and the cause of the fault is 6 km ahead of the primary location L 1, the result is a parameter of P = 30% to be transmitted.
Bei dem Ausführungsbeispiel nach Fig. 2 liegt zwischen den beiden Orten L1 und L2 ein weiterer Ort L3, der auch in der Ortsdatenbank aufgeführt ist. Für die gleiche Störung S zwischen den Punkten X und Y wird dann eine TMC-Meldung übertragen, die besagt, daß vor dem Ort L1 eine Störung mit dem Ausmaß 2 vorliegt, was ohne weitere Angaben bedeuten kann, daß die gesamte Strecke zwischen L1 und L2 von der Störung betroffen ist.In the embodiment of Fig. 2 is located between the two locations L1 and L2 another location L3, which is also listed in the location database. For the same disturbance S between the points X and Y, a TMC message is then transmitted stating that there is an error of magnitude 2 in front of the location L1, which without further indication can mean that the entire distance between L1 and L2 affected by the disorder.
Bei einer Codierung nach Fig. 2 wird jedoch im Gegensatz zu Fig. 1 der Streckenanteil D nicht auf die Entfernung zwischen L1 und L2, sondern auf die Entfernung A' zwischen L1 und L3 bezogen, so daß die Position X mit größerer Genauigkeit übertragen wird. Der zu übertragende Parameter berechnet sich dann zu P' = D•100/A'.In an encoding of Fig. 2, however, unlike Fig. 1, the link D is not related to the distance between L1 and L2 but to the distance A 'between L1 and L3, so that the position X is transmitted with greater accuracy. The parameter to be transmitted is then calculated as P '= D • 100 / A'.
P bzw. P' wird dann als Datentelegramm mit der Kennung Label 15 zum Empfänger übertragen. Wird die gleiche Codiertabelle benutzt wie bei Qualifier 3, ergibt sich als 5-Bit-Wert eine 6, die in das dem Label 15 folgende Datenfeld eingetragen wird. Die Decodierung im Empfänger erfolgt beispielsweise über eine Look-up-Tabelle.P or P 'is then transmitted as a data telegram with the identifier label 15 to the receiver. If the same coding table is used as in qualifier 3, the result is a 5-bit value of 6, which is entered in the data field following label 15. The decoding in the receiver takes place, for example, via a look-up table.
Basierend auf dieser Information kann der Empfänger zum einen die Position des Punktes X und zum anderen unter Ausnutzung der ebenfalls übertragenen Störungslänge L die Position des Punktes Y berechnen. Wie in Fig. 3 dargestellt, können in Verbindung mit einem Navigationssystem, das über eine digitale Karte verfügt, diese Informationen genutzt werden, um den Fahrer dicht an das Stauende heranzuführen und nach Umfahrung des Staus früher wieder auf die ursprüngliche Strecke zurückzuführen.Based on this information, the receiver can calculate the position of the point X on the one hand, and the position of the point Y on the other hand, using the also transmitted disturbance length L. As shown in Fig. 3, in conjunction with a navigation system having a digital map, this information can be used to bring the driver close to the end of the jam and return to the original route earlier after bypassing the jam.
Fig. 3 zeigt die gleiche Strecke wie Fig. 2 mit den Orten L1, L2 und L3 sowie der Störung S zwischen den Punkten X und Y. Außerdem sind weitere Orte 01 bis 07 dargestellt, von denen mindestens die Orte 01 und 03 in den zur Codierung und Decodierung verwendeten Ortsdatenbanken nicht eingetragen sind. Bei der erfindungsgemäßen Übertragung der Position von Stauanfang X und Stauende Y kann der Fahrer über die Orte 01, 02 und 03, also über eine kürzere Umleitungsstrecke als ohne die Anwendung des erfindungsgemäßen Verfahrens, geleitet werden, wobei er über die Orte 04, 05, 06 und 07 geführt werden müßte.Fig. 3 shows the same route as Fig. 2 with the locations L1, L2 and L3 and the disturbance S between the points X and Y. In addition,
Alternativ zu der Verwendung des Labels 15 kann das Label 12 genutzt werden. Für diesen ist in ALERT-C bereits ein 16-Bit-Feld für den Wert vorgesehen. Damit kann die Position bei Bedarf mit einer höheren Auflösung (etwa in 100%/65536) übertragen werden. Sinngemäß ist das Verfahren auch mit anderen als prozentuellen Angaben des Streckenanteils, d.h. als absoluter oder relativer Abstand, beispielsweise in Längeneinheiten oder mit Label 2 oder mit Label 5, Quantifier 9, oder durch Einführung einer neuen Tabelle (entsprechend Gebrauch mit Quantifier, siehe ENV12313-2), möglich.As an alternative to the use of the label 15, the label 12 can be used. ALERT-C already has a 16-bit field for the value. This allows the position to be transmitted with a higher resolution (eg in 100% / 65536) if required. Analogously, the method is also used with other than percentage information of the track share, i. as absolute or relative distance, for example in units of length or with label 2 or with label 5, quantifier 9, or by introducing a new table (corresponding to use with quantifier, see ENV12313-2).
