Description

Die Erfindung bezieht sich auf ein Verkehrsmanagementsystem zur Bereitstellung von Verkehrsinformationen und zur Verkehrssteuerung und -beeinflussung in einem Straßennetz einer Stadt nach dem Oberbegriff des Patentanspruches 1.The invention relates to a traffic management system for providing traffic information and for traffic control and influencing in a street network of a city according to the preamble of claim 1.

Ein derartiges Verkehrsmanagementsystem ist aus der Produktschrift "SITRAFFIC Concert, SITRAFFIC Scala und SITRAFFIC Guide: Drei Aufgaben - eine gemeinsame Plattform", herausgegeben 2008 von der Siemens AG, Bestell-Nr. E10003-A800-A64-V1, bekannt. Die Verkehrsmanagementzentrale besitzt offene Schnittstellen zu verkehrsstrategisch relevanten Systemen, wie zum Beispiel der Feuerwehrzentrale, behördlichen Baustellensystemen, Parkzentralen, Lichtsignalanlagen der Tiefbauämter, Zentralen der Verkehrsbetriebe oder Verwaltungssysteme von Sportarenen und sonstigen Veranstaltungsstätten, um deren Datenmaterial für ein strategisches Verkehrsmanagement nutzen zu können. Offene Schnittstellen dienen aber auch dazu, zuverlässige Verkehrsinformationen an verschiedenste externe Dienstbereitsteller weiterzugeben. Basierend auf diesen Daten können Navigationssysteme den Benutzer sicher und auf schnellstem Weg ans Ziel führen und dabei automatisch Staus und Umleitungen berücksichtigen. Per Internet und Radio verbreitete Stauwarnungen, Verkehrsinformationen und Reisezeitberechnungen helfen zudem, die verkehrstechnisch günstigste Route zu finden. Die Verkehrsmanagementzentrale bietet darüber hinaus direkt Einflussnahme auf dynamische Anzeigetafeln mit Umleitungsempfehlungen, Glätte-, Nebel- oder Stauwarnungen und Geschwindigkeitsbegrenzungen.Such a traffic management system can be found in the product brochure "SITRAFFIC Concert, SITRAFFIC Scala and SITRAFFIC Guide: Three tasks - one common platform", published in 2008 by Siemens AG, order no. E10003-A800-A64-V1, known. The traffic management center has open interfaces to traffic-strategically relevant systems, such as the fire brigade center, official building site systems, parking centers, traffic signal systems of the civil engineering offices, central offices of the transport companies or administrative systems of sports arenas and other event venues in order to use their data for strategic traffic management. Open interfaces also serve to pass on reliable traffic information to a wide variety of external service providers. Based on this data, navigation systems can guide the user safely and quickly to their destination and automatically take traffic jams and diversions into account. Traffic jam warnings, traffic information and travel time calculations distributed via the Internet and radio also help to find the best route in terms of transport technology.

Verkehrsmanagementsysteme sind beispielsweise auch aus den Veröffentlichungen US 2011/0034183 A1 und DE 102 00 002 A1 bekannt.Traffic management systems are also from the publications, for example US 2011/0034183 A1 and DE 102 00 002 A1 known.

Dynamische straßenseitige Informationstafeln, der gesprochene Rundfunk und der sogenannte TMC-Dienst des Radio-Data-Systems weisen eine geringe Flexibilität und eine eingeschränkte Leistungsfähigkeit hinsichtlich des Inhalts der Informationsmeldungen auf. Das Internet ist nicht auf den einzelnen Verkehrsteilnehmer und auf die lokale Relevanz der jeweiligen Information zugeschnitten.Dynamic street-side information boards, the spoken radio and the so-called TMC service of the radio data system have a low flexibility and a limited performance with regard to the content of the information messages. The Internet is not tailored to the individual road user and the local relevance of the respective information.

Aus der EP 1 006 684 A2 ist ein Verfahren zum Übertragen von Verkehrsinformationen von einer Zentrale an ein Mobilfunkendgerät über einen Übertragungskanal bekannt. In der Zentrale gehen Verkehrsdaten von im Verkehr mitfahrenden Fahrzeugen und/oder stationären Detektoren und/oder anderen Quellen, wie Meldebehörden, ein und werden dort gegebenenfalls überarbeitet. Die Verkehrsinformationen betreffen einen Ort und eine Art eines Ereignisses, beispielsweise eine Autobahnnummer und die Länge eines Staus darauf. Die Verkehrsinformationen werden mittels zweidimensionaler Kodiertabellen (Ort, Ereignis) kodiert, um über den Übertragungskanal komprimiert übertragen zu werden. Hierdurch können Verkehrsinformationen in eine Funkzelle des Mobilfunknetzes gesendet werden, welche für diese Funkzelle örtlich und/oder zeitlich von Bedeutung sind, beispielsweise Staumeldungen. Im Mobilfunkendgerät werden die Verkehrsinformationen mittels eine Dekodiertabelle dekodiert. Um den Speicher in Mobilfunkendgerät klein zu halten, werden in mit Verkehrsinformationen unbelegte Lücken Tabelleninformationen von der Zentrale an die Mobilfunkendgeräte übertragen. Um in der Zentrale festzustellen, in welche örtlichen Bereiche - also in welche Gruppe von Funkzellen - welche Verkehrsinformationen zu übertragen sind, ist in der Zentrale eine weitere Tabelle vorgesehen, die Auswahlkriterien zur Auswahl von Funkzellen anhand der zu sendenden Verkehrsinformationen umfasst. Die Sendung erfolgt als Mobilfunk-Kurznachrichten-Cellbroadcast-Sendung.From the EP 1 006 684 A2 a method for transmitting traffic information from a center to a mobile radio terminal via a transmission channel is known. Traffic data from vehicles traveling in traffic and / or stationary detectors and / or other sources, such as registration authorities, are received at the head office and are revised there if necessary. The traffic information relates to a location and a type of event, for example a motorway number and the length of a traffic jam thereon. The traffic information is encoded using two-dimensional coding tables (location, event) in order to be transmitted in compressed form via the transmission channel. As a result, traffic information can be sent into a radio cell of the mobile radio network, which are important for this radio cell in terms of location and / or time, for example traffic jam reports. The traffic information is decoded in the mobile radio terminal using a decoding table. In order to keep the memory in the mobile radio terminal small, table information is transmitted from the control center to the mobile radio terminals in gaps not occupied by traffic information. In order to determine in the head office which traffic areas are to be transmitted in which local areas - that is to say in which group of radio cells - a further table is provided in the head office, which includes selection criteria for selecting radio cells on the basis of the traffic information to be transmitted. The broadcast is a cell phone short broadcast cell broadcast broadcast.

Die Aufgabe wird erfindungsgemäß gelöst durch ein gattungsgemäßes Verkehrsmanagementsystem mit den im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmalen. Demnach umfasst das Verkehrsmanagementsystem ein von einem Verkehrsteilnehmer mitführbares Endgerät zum Empfang und zur Ausgabe der Informationsmeldung. Der Verkehrsteilnehmer führt als Informationsempfänger ein mobiles Endgerät, insbesondere ein sogenanntes Smartphone oder ein Fahrzeugbordgerät, mit sich, mittels dessen ein zugehöriges Applikationsprogramm zum Empfangen und Ausgeben von Informationsmeldungen ausführbar ist. Dabei wird in vorteilhafter Weise die zunehmende Verfügbarkeit von Smartphones für eine umfassende Verbreitung von Informationsmeldungen ausgenutzt. Ferner umfasst das Verkehrsmanagementsystem Datenübertragungsmittel zur Übermittlung der Informationsmeldung von der Verkehrsmanagementzentrale an das Endgerät. Außerdem sind die Mittel zur zentralen Erzeugung einer Informationsmeldung für Verkehrsteilnehmer ferner zur geographischen Verortung der Informationsmeldung durch Zuordnung einer Ortskennung zur zielorientierten Übermittlung und/oder Ausgabe der verorteten Informationsmeldung ausgebildet. Dabei repräsentiert die Ortskennung einen die Informationsmeldung betreffenden Ort oder Ausschnitt des Verkehrsnetzes. Die Datenübertragungsmittel weisen mehrere, strategisch im Straßennetz der Stadt verteilt angeordnete Verteilereinrichtungen auf, die zur leitungsgebundenen und/oder drahtlosen Datenübertragung mit der Verkehrsmanagementzentrale verbunden sind und jeweils eine Sendeeinheit zur drahtlosen Übermittlung von Informationsmeldungen an Endgeräte innerhalb eines lokalen Sendebereichs umfassen, wobei eine Informationsmeldung anhand ihrer Ortskennung gezielt an eine oder mehrere Verteilereinrichtungen übertragbar ist. Die Verteilereinrichtungen sind dabei straßenseitig im Straßennetz an verkehrstechnisch relevanten Orten angeordnet. Die Sendeeinheiten weisen einen lokalen Sendebereich mit einer Reichweite zwischen 50 m und 300 m auf und sind als WLAN-Sender ausgebildet.The object is achieved according to the invention by a generic traffic management system with the features specified in the characterizing part of patent claim 1. Accordingly, the traffic management system comprises a terminal device that can be carried by a road user to receive and output the information message.

Der Kern des erfindungsgemäßen Verkehrsmanagementsystems liegt in einer örtlich selektierten, gezielten Informationsübermittlung direkt zum Verkehrsteilnehmer im sich bewegenden Verkehr, zum Beispiel im Fahrzeug. Das vorgeschlagene Verkehrsmanagementsystem umfasst die gesamte Prozesskette von Dateneingabe, Datenverarbeitung, Datenübermittlung und Datenausgabe und stellt dadurch ein integriertes Element des Verkehrsmanagements dar. Die Einbindung in das Strategiemodul des Verkehrsmanagementsystems ermöglicht die abgestimmte, inhaltlich konsistente Information über verschiedene Informationskanäle, wie zum Beispiel den gesprochenen Rundfunk, straßenseitige Informationsanzeigen, das Internet oder den RDS/TMC-Dienst, was zu Synergieeffekten führt. Die Erfindung nutzt mit Vorteil gerade in einer Verkehrsmanagementzentrale vorliegende Informationen und Expertenwissen aus, um den Verkehrsteilnehmer aktuell zu informieren und den Verkehr strategisch zu beeinflussen. Der Operator in der Verkehrsmanagementzentrale kennt die neuralgischen Punkte im Verkehrsnetz der Stadt oder des Ballungsraumes, geplante Veranstaltungen und Eingriffe in den Verkehr durch Sperrungen oder Baustellen, den angebundenen Parkraum sowie die aktuelle Verkehrssituation. Dies ermöglicht eine vernetzte Betrachtung des Verkehrs und eine darauf basierende Definition der Informationsmeldungsinhalte. Als Nutzer des erfindungsgemäßen Verkehrsmanagementsystems kommen vor allem Verkehrsinfrastrukturbetreiber, wie Städte und Kommunen, und Veranstaltungsorganisatoren etwa von Messen und großen Sport- oder Kulturveranstaltungen in Betracht. Für die Datenübertragungsschnittstelle zwischen der Verkehrsmanagementzentrale und den straßenseitigen Verteilereinrichtungen kommen beispielsweise Kabel und Ethernet oder Mobilfunk, insbesondere der paketvermittelnde Radiodatenübertragungsdienst, kurz GPRS, in Betracht. Die Verteilereinrichtungen werden an strategisch wichtigen Punkten im Verkehrsnetz, zum Beispiel an Hauptzufahrtsstraßen, an Tunneln, an Messegeländen, Sportarenen, Tierparks und dergleichen, installiert und umfassen eine Empfangseinheit für die Informationsmeldungen und eine Sendeeinheit mit lokalem Sendebereich, die insbesondere als WLAN-Sender ausgebildet sein kann und zur Ausstrahlung der Informationsmeldungen lokal um die Verteilereinrichtung dient. Eine gezielte Übermittlung der Informationsmeldungen auf die verschiedenen Verteilereinrichtungen berücksichtigt die jeweiligen Netzausschnitte, auf die ein städtischer Brennpunkt Einfluss hat.
