Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur automatischen Zuordnung von Störungen repräsentierenden Verkehrsmeldungen und die Stürungsursache oder Hinweise repräsentierenden Zusatzinformationen. Im Straßenverkehr können sich Verkehrszustände sehr schnell ändern. Aufgrund eines hohen Verkehrsaufkommens und des individuellen Fahrverhaltens der Verkehrsteilnehmer entstehen statistische Schwankungen im Verkehrsfluß, die bereits alleine zu starken Verkehrsbeeinträchtigungen führen können. Hinzu kommen noch dynamisch wechselnde streckenbezogene Randbedingungen in Form von Geschwindigkeitsbegrenzungen, Änderungen in der Anzahl der Fahrspuren, Wetteränderungen, Steigungen, Baustellen usw., die zu Veränderungen in der Verkehrssituation in schwer vorhersehbarer Weise beitragen.The invention relates to a method and a device for automatic assignment traffic reports and the cause of the malfunction or Additional information representing notes. In road traffic can Change traffic conditions very quickly. Due to high traffic and the individual driving behavior of road users are statistical Fluctuations in traffic flow that are already too strong alone Can cause traffic disruption. Added to this are dynamic changing route-related boundary conditions in the form of Speed limits, changes in the number of lanes, Weather changes, gradients, construction sites etc. that lead to changes in the Contribute to the traffic situation in a way that is difficult to predict.
Den Verkehrsteilnehmern werden solche Verkehrsbeeinträchtigungen in Form von Verkehrsmeldungen über unterschiedliche Informationskanäle zur Kenntnis gebracht. So erfahren sie den Verkehrszustand sowie den Ort und die Länge einer Störung und können entsprechend darauf reagieren.Such traffic impairments are presented to road users in the form of Traffic announcements brought across various information channels. In this way, they learn about the state of traffic, the location and length of a fault and can react accordingly.
Um den Autofahrern auch den Grund einer Verkehrsstörung mitzuteilen, sollen diese Verkehrsmeldungen um Zusatzinformationen, welche die Ursache der Störung näher charakterisieren, ergänzt werden.In order to inform drivers of the reason for a traffic disruption, they should Traffic reports for additional information, which the cause of the disturbance closer characterize, be supplemented.
Es ist kein Verfahren bekannt, welches strecken- oder punktbezogene Zusatzinformationen automatisch nach einem Zuordnungskriterium dynamischen Verkehrsdomänen oder überhaupt Verkehrsmeldungen hinzufügt. No method is known which is route or point related Additional information automatically dynamic according to an assignment criterion Adds traffic domains or traffic reports at all.
Aufgabe der vorliegenden Erfindung ist das Ermöglichen einer möglichst automatischen, zuverlässigen, stabilen Zuordnung von punkt- oder streckenbezogenen, die Ursache von in Verkehrsmeldungen genannten Verkehrsstörungen repräsentierenden Zusatzinformationen zu von der Verkehrsmeldung bezeichneten Bereichen des Straßenverkehrsnetzes, insbesondere zu Verkehrsdomänen. Verkehrsdomänen sind Bereiche und/oder Strecken eines Straßenverkehrsnetzes mit hinreichend ähnlichen Verkehrseigenschaften (wie Geschwindigkeiten, Fluss, Verkehrsdichte, abgeleitete Parameter usw.). Die Aufgabe wird durch die Gegenstände der unabhängigen Ansprüche gelöst.The object of the present invention is to enable one as possible automatic, reliable, stable assignment of point or route-related, the cause of those mentioned in traffic reports Additional information representing traffic disruptions to the Traffic message designated areas of the road network, in particular to traffic domains. Traffic domains are areas and / or routes of one Road network with sufficiently similar traffic characteristics (such as Speeds, flow, traffic density, derived parameters, etc.). The task is solved by the subjects of the independent claims.
Bei der Realisierung dieser Zielsetzungen werden folgende Probleme gelöst:
Eine wesentliche Eigenschaft der Verkehrsdomänen ist es, dass sie sich dynamisch
verändern. Sie breiten sich aus, sie wachsen, teilen sich auf, wandern, verschmelzen,
bis sie sich auflösen und wieder freie Fahrt besteht. Dies bedeutet, dass eine
Verkehrsdomäne nicht ohne weiteres einer streckenbezogenen Ursache, welche im
Falle einer Baustelle z.B. durch den Kilometerwert ihres Beginns und ihres Endes auf
einer Straße angegeben ist, stabil zugeordnet werden kann. Ein einfaches
Überlappungskriterium reicht nicht aus, da es zu hin- und herspringenden
Meldungsattributen führen kann, je nachdem, wie die Verkehrsdomäne wandert.The following problems are solved in realizing these objectives:
An essential property of the traffic domains is that they change dynamically. They spread, they grow, they divide, they hike, they merge until they dissolve and there is free movement again. This means that a traffic domain cannot easily be assigned to a route-related cause, which in the case of a construction site is indicated, for example, by the mileage of its start and end on a road. A simple overlap criterion is not enough as it can lead to jumping message attributes depending on how the traffic domain is moving.
Erfindungsgemäß sind diese Probleme, insbesondere auch das der stabilen Zuordnung von streckenbezogenen Zusatzinformationen zu Verkehrsmeldungen und dynamischen Verkehrsdomänen, lösbar durch Verwendung einer Hysterese bei der Entscheidung über die Zuordnung von Zusatzinformationen zu Verkehrsmeldungen.According to the invention, these problems, in particular also those of the stable ones Assignment of route-related additional information to traffic reports and dynamic traffic domains, solvable by using a hysteresis in the Decision on the assignment of additional information to traffic reports.
Das Verfahren ist auf allen Autobahnen, Schnell- und Landstraßen zur weitergehenden Information der Autofahrer einsetzbar. Diese um Zusatzinformationen ergänzten Verkehrsmeldungen sind auch geeignet zur Erstellung von Reisezeitprognosen und Umleitungsempfehlungen sowie zur direkten Fahrzeugbeeinflussung und Verkehrslenkung sowie für zahlreiche andere Dienste.The procedure is to be continued on all motorways, expressways and country roads Information for drivers can be used. This supplemented with additional information Traffic reports are also suitable for creating travel time forecasts and Detour recommendations as well as for direct vehicle influence and Traffic control as well as for numerous other services.
Weitere Merkmale ergeben sich aus der Beschreibung eines Ausführungsbeispiels und aus den Ansprüchen. Further features result from the description of an exemplary embodiment and from the claims.
Zu Beginn eines Aktualisierungslaufes von Verkehrsmeldungen liegt eine Liste mit strecken- und/oder punktbezogenen Zusatzinformationen vor, welche jeweils Verkehrsmeldungen in einer Liste von Verkehrsmeldungen zugeordnet werden sollen. Kann eine Zuordnung vorgenommen werden, so wird die Verkehrsmeldung um die Zusatzinformation als Ursache oder Hinweis ergänzt.At the beginning of an update run of traffic reports there is a list with route and / or point-related additional information, which each Traffic reports are to be assigned in a list of traffic reports. If an assignment can be made, the traffic announcement is changed to Additional information added as cause or hint.
Zusatzinformationen sind z.B. Baustellenbereiche, Steigungs- oder Gefällstrecken, Bereiche mit fester Spurzahl, Bereiche mit Geschwindigkeitsbeschränkungen, Streckenabschnitte mit schlechten Wetter- oder Fahrbahnbedingungen, Unfallorte oder Punkte mit Spurzahländerungen. Diese Informationen können aus verschiedenen Quellen bezogen werden, z.B. von Autobahnmeistereien, aus entsprechenden Seiten des Internets, von Landesmeldestellen, vom ADAC, von Hubschrauberüberwachungen, von Einzelangaben von Verkehrsteilnehmern, von der Polizei usw.Additional information is e.g. Construction site areas, inclines or descents, Areas with a fixed number of lanes, areas with a speed limit, Route sections with bad weather or road conditions, accident locations or Points with track number changes. This information can come from various Sources are obtained, e.g. by highway authorities, from relevant pages of the Internet, of state registration offices, of ADAC, of Helicopter surveillance, of individual details of road users, of the Police etc.
Über ein Überlappungskriterium wird der Grad der Überlappung zwischen den Geltungsbereichen der Verkehrsmeldungen einerseits und den Zusatzinformationen andererseits bestimmt. Ergebnis kann z.B. eineÜberlappung auf einer Strecke von 2 Kilometern sein.An overlap criterion is used to determine the degree of overlap between the Scope of the traffic reports on the one hand and the additional information otherwise determined. Result can e.g. an overlap over a distance of 2 Kilometers.
Um ein normiertes Maß, das auch einheitlich vergleichbar ist, zu erhalten werden
zusätzlich die Längen der Geltungsbereiche der Verkehrsdomänen und der
Zusatzinformationen verwendet. Beispielsweise kann es für eine Baustelle wie folgt
festgelegt werden:
Je nach verkehrstechnischer Bedeutung der Zusatzinformationen können auch Bereiche vor oder nach den Geltungsbereichen der Zusatzinformationen verwendet werden, z.B. eine Strecke von 2 km Länge vor einer Baustelle. Andere verkehrstechnisch sinnvolle Größen können hier ebenfalls berücksichtigt werden, z.B. als Gewichtsfaktoren. Depending on the traffic-related importance of the additional information, you can also Areas used before or after the scope of the additional information e.g. a distance of 2 km in front of a construction site. Other Traffic-relevant variables can also be considered here, e.g. as weight factors.
Für punktbezogene Zusatzinformationen kann das vorhergehende Kriterium des Überlappungsgrades ebenfalls verwendet werden, indem man diesen Informationen einen verkehrstechnisch sinnvollen Geltungsbereich zuweist, z.B. 2 km vor einer Fahrbahnverengung.For point-related additional information, the previous criterion of Overlap levels can also be used by looking at this information assigns a scope that is useful in terms of transport technology, e.g. 2 km before one Road narrows.
Die Überlappung kann aus den Anfangs- und Endpunkten der Geltungsbereiche der Verkehrsmeldungen und der Zusatzinformationen bestimmt werden, die Geltungsbereiche können aber auch in Form von mehr oder weniger stark gewichteten Indikatoren, welche jeweils für kleine Intervalle von z.B. 200 Metern gelten, entlang einer Straße berücksichtigt werden.The overlap can be from the start and end points of the scope of the Traffic announcements and additional information can be determined Scope can also be in the form of more or less heavily weighted Indicators, each for small intervals of e.g. Apply 200 meters along of a street.
Der Grad der Überlappung kann dann verglichen werden mit einem Schwellwert, z.B. 0,5, welcher darüber entscheidet, ob die Zusatzinformation einer Verkehrsmeldung als Ursache oder Hinweis zuzuordnen ist.The degree of overlap can then be compared to a threshold, e.g. 0.5, which decides whether the additional information of a traffic report as Cause or note can be assigned.
Da die von Verkehrsmeldungen betroffenen Bereiche bzw. Verkehrsdomänen sich jedoch dynamisch verhalten, also wachsen, schrumpfen und wandern können, und dies auch einige Zusatzinformationen tun können (z.B. Bereiche örtlicher Wetterlagen), wäre diese Vorgehensweise alleine jedoch problematisch. Es wird daher zusätzlich eine Hysterese für den Grad der Überlappung verwendet, welche die Zuordnung in aufeinanderfolgenden Aktualisierungsläufen für die Verkehrsmeldungen stabilisiert. Es ist daher wichtig, dass zunächst aus dem Überlappungsgrad noch keine diskrete Entscheidung für eine Zuordnung getroffen wird.Because the areas or traffic domains affected by traffic reports differ however behave dynamically, i.e. can grow, shrink and migrate, and some additional information can do this (e.g. areas of local weather conditions), this procedure alone would be problematic. It will therefore be additional uses a hysteresis for the degree of overlap, which the assignment in successive update runs for the traffic reports stabilized. It It is therefore important that there is no discrete one from the degree of overlap Decision for an assignment is made.
Über die Hystereseparameter, z.B. die Schwellen 0,4 und 0,6, für den
Überlappungsgrad wird festgelegt, ob eine Zuordnung erfolgt. Ist einer
Verkehrsmeldung bereits eine bestimmte Zusatzinformation zugeordnet worden, so
muss der Überlappungsgrad unter die untere Schwelle (hier 0,4) sinken, um die
Zusatzinformation nicht mehr dieser Verkehrsmeldung zuzuordnen. Ist eine
Zusatzinformation dagegen noch nicht einer Verkehrsmeldung zugeordnet worden, so
muss der Überiappungsgrad über die obere Schwelle (hier 0,6) ansteigen, damit eine
Zuordnung vorgenommen wird.
Ein Hin- und Herspringen der Zuordnung wird so vermieden, wenn sich der
Überlappungsgrad z.B. hier in der Nähe von 0,5 einstellen würde. The hysteresis parameters, for example the thresholds 0.4 and 0.6, for the degree of overlap determine whether an assignment is made. If certain additional information has already been assigned to a traffic report, the degree of overlap must drop below the lower threshold (here 0.4) in order to no longer assign the additional information to this traffic report. If, on the other hand, additional information has not yet been assigned to a traffic announcement, the degree of overlap must rise above the upper threshold (here 0.6) so that an assignment is made.
A jump back and forth of the assignment is avoided if the degree of overlap would be close to 0.5, for example.
Das Verfahren wird zyklisch für alle Verkehrsdomänen bzw. für alle zu betrachtenden Strecken zur Aktualisierung der ermittelten Informationen angewendet.The procedure becomes cyclical for all traffic domains or for all to be considered Routes used to update the information obtained.
Eine Verkehrsmeldung und eine zugeordnete Zusatzinformation können über unterschiedliche Medien wie Radio, DRB, Mobilfunkkurznachrichten an einen Endgerätnutzer, Gruppen von Endgerätnutzem oder als Rundspruchnachricht (z.B. SMS-CB) ausgesendet werden.A traffic announcement and an assigned additional information can via different media such as radio, DRB, cell phone short messages to one Terminal users, groups of terminal users or as a broadcast message (e.g. SMS-CB) can be sent.
