Bei einer Einsatzfahrt eines Einsatzfahrzeuges mit Sonderbefugnissen, beispielsweise eines Rettungs-, Feuerwehr- oder Polizeifahrzeugs, spielt Zeit die entscheidende Rolle für die Rettung von Menschenleben. Dabei kommt es vor allem im städtischen Verkehrswegenetz durch den dichten Verkehr und die Enge im Straßenraum bei Einsatzfahrten trotz Blaulicht und Martinshorn häufig zu kritischen Verzögerungen. Darüber hinaus besteht während einer Einsatzfahrt ein erhebliches Unfallrisiko für ein Einsatzfahrzeug und damit für Fahrzeuge des allgemeinen Verkehrs.In a mission of a rescue vehicle with special powers, such as a rescue, fire or police vehicle, time plays the crucial role in saving lives. This is especially due to the dense traffic and the narrowness in the street in case of emergency operations despite blue light and siren frequently critical delays especially in the urban traffic network. In addition, there is a significant accident risk during an operational trip for a rescue vehicle and thus for vehicles of general traffic.
Die Offenlegungsschrift
Aus der Offenlegungsschrift
In der
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verkehrssteuerungssystem der eingangs genannten Art bereitzustellen, welches eine dynamische Freischaltung eines Fahrweges für ein Einsatzfahrzeug bei Änderungen der Einsatzroute während der Einsatzfahrt ermöglicht und dabei trotzdem einfach aufgebaut ist, insbesondere ohne eine direkte Kommunikation zwischen Einsatzfahrzeug und Lichtsignalanlage auskommt.The invention is therefore an object of the invention to provide a traffic control system of the type mentioned above, which allows dynamic activation of a route for an emergency vehicle with changes in the mission route during the mission and still has a simple structure, especially without direct communication between emergency vehicle and traffic lights ,
Die Aufgabe wird erfindungsgemäß gelöst durch ein gattungsgemäßes Verkehrssteuerungssystem mit den im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmalen. Demnach sind die Verkehrsrechnerzentrale und die Einsatzleitzentrale über eine Schnittstelle zur Datenübertragung gekoppelt, über welche die bestimmte Einsatzroute beschreibende Routendaten von der Einsatzleitzentrale an die Verkehrsrechnerzentrale übertragbar sind. Durch das Zusammenspiel von Einsatzleitsystem und Verkehrsrechnerzentrale kann die zeitliche Folge an Freigabephasen wie auch die Einsatzroute in Abhängigkeit der tatsächlichen Gegebenheiten dynamisch modifiziert werden. Eine Kommunikation zwischen Einsatzfahrzeug und Lichtsignalanlagen oder der Verkehrsrechnerzentrale ist nicht erforderlich. Damit können sowohl die von den Einsatzfahrzeugen mitgeführten Fahrzeuggeräte einfacher und kostengünstiger ausgeführt werden als auch auf eine zusätzliche Infrastruktur an den Knotenpunkten verzichtet werden.The object is achieved by a generic traffic control system with the features specified in the characterizing part of
In einer vorteilhaften Ausführungsform des erfindungsgemäßen Verkehrssteuerungssystems ist die Verkehrsrechnerzentrale dazu ausgebildet, anhand der übertragenen Routendaten die auf der Einsatzroute liegenden Knotenpunkte und jeweils die Freigabephase der zugeordneten Lichtsignalanlage für eine Freischaltung der Einsatzroute über den Knotenpunkt zu identifizieren. In der Einsatzleitzentrale wird anhand des aktuellen Standortes des Einsatzfahrzeuges und anhand des Einsatzortes beispielsweise mit Hilfe eines Geografischen Informationssystems die Einsatzroute geplant und entsprechende Routendaten über die Schnittstelle an die Verkehrsrechnerzentrale übermittelt. Auf Grundlage der Routendaten können in der Verkehrsrechnerzentrale die auf der Einsatzroute liegenden Knotenpunkte bestimmt und je Knotenpunkt diejenigen Freigabephasen - also beispielsweise Geradeausfahrer, Links- oder Rechtsabbieger - ermittelt werden, die zu schalten sind, um an eben den Verkehrsstrom ein Freigabesignal abzugeben, der den Knotenpunkt auf dem freizuschaltenden Fahrweg passiert.In an advantageous embodiment of the traffic control system according to the invention, the traffic control center is adapted to identify based on the transmitted route data lying on the deployment route nodes and each release phase of the associated traffic signal for activation of the deployment route via the node. In the operations control center, the mission route is planned on the basis of the current location of the emergency vehicle and on the basis of the deployment site, for example with the aid of a geographical information system, and corresponding route data is transmitted via the interface to the traffic control center. Based on the route data, the nodes located on the route can be determined in the traffic computer center and those release phases - ie, for example, straight-line driver, left or right turn - are determined, which are to be switched to deliver to just the traffic flow an enable signal, the node happened on the track to be unlocked.
Bei dem erfindungsgemäßen Verkehrssteuerungssystem ist die Verkehrsrechnerzentrale dazu ausgebildet, aktuelle Verkehrsinformationen zum Verkehrswegenetz bereitzustellen und diese beschreibende Verkehrsdaten über die Schnittstelle an die Einsatzleitzentrale zu übertragen, und es ist die Einsatzleitzentrale dazu ausgebildet, die Einsatzroute unter Berücksichtigung der übertragenen Verkehrsdaten zu bestimmen. Hierdurch können in der Verkehrsrechnerzentrale vorliegende Verkehrsinformationen, wie zum Beispiel die aktuelle Verkehrssituation im betrachteten Verkehrswegenetz, etwa die aktuelle mittlere Reisezeit auf den Streckenabschnitten des Netzes, oder aber bekannte Baustellen oder Straßensperrungen, an die Einsatzleitzentrale zur Planung von Einsatzrouten übertragen werden. Durch Berücksichtigung derartiger Verkehrsdaten in der Einsatzleitzentrale können Einsatzrouten bestimmt werden, die möglicherweise von der Strecke her nicht die kürzesten sind, auf welchen die Einsatzfahrzeuge aber mit weniger Behinderungen und damit schneller an den Einsatzort gelangen.In the traffic control system according to the invention, the traffic control center is adapted to provide current traffic information to the traffic route network and to transmit this descriptive traffic data via the interface to the deployment control center, and it is formed the mission control center to determine the mission route taking into account the transmitted traffic data. As a result, traffic information present in the traffic control center, such as the current traffic situation in the considered traffic route network, such as the current average travel time on the sections of the network, or known construction sites or road closures, are transmitted to the deployment control center for planning deployment routes. By including such traffic data in the dispatch center, deployment routes may be determined that may not be the shortest on the route to which the Emergency vehicles but with less disabilities and thus reach the place of use faster.
In einer vorteilhaften Ausgestaltung des erfindungsgemäßen Verkehrssteuerungssystems ist die Einsatzleitzentrale dazu ausgebildet, eine Einsatzroute neu zu bestimmen, wenn das Einsatzfahrzeug die zuvor bestimmte Einsatzroute verlässt und/oder wenn geänderte Verkehrsinformationen eine günstigere Einsatzroute bedingen. Eine Neubestimmung einer Einsatzroute kann dadurch ausgelöst werden, wenn die fortwährende Übertragung von aktuellen Positionsdaten aus dem Fahrzeuggerät des Einsatzfahrzeuges ergibt, dass das Einsatzfahrzeug von der ursprünglich geplanten Einsatzroute abgewichen ist - dies kann durch einen versehentlichen Fahrfehler oder absichtlich bei Umfahrung einer lokalen Verkehrsstörung passieren. Eine Neubestimmung einer Einsatzroute kann aber auch durch eine sich ändernde Verkehrssituation bedingt sein, was aufgrund der fortwährenden Übertragung von aktuellen Verkehrsdaten aus der Verkehrsrechnerzentrale erkennbar ist. Hierzu wird in der Einsatzzentrale fortlaufend bewertet, ob sich ändernde Verkehrsinformationen eine günstigere Resteinsatzroute, gerechnet vom aktuellen Standort des Einsatzfahrzeugs, als die ursprünglich bestimmte bedingen.In an advantageous embodiment of the traffic control system according to the invention, the deployment control center is designed to redetermine a deployment route when the emergency vehicle leaves the previously determined deployment route and / or when altered traffic information necessitates a more favorable deployment route. A redetermination of a task route can be triggered if the continuous transmission of current position data from the vehicle equipment of the emergency vehicle results in the emergency vehicle deviating from the originally planned mission route - this can be due to an accidental driver error or intentional bypassing of a local traffic incident. However, a redefinition of a task route can also be caused by a changing traffic situation, which is recognizable due to the continuous transmission of current traffic data from the traffic control center. For this purpose, it is continuously evaluated in the operations center, whether changing traffic information a cheaper residual route of use, calculated from the current location of the emergency vehicle, than the originally determined condition.
In einer bevorzugten Ausführungsform des erfindungsgemäßen Verkehrssteuerungssystems ist das Fahrzeuggerät dazu ausgebildet, laufend den aktuellen Standort des Einsatzfahrzeugs zu bestimmen und den bestimmten Standort beschreibende Positionsdaten an die Einsatzleitzentrale zu übertragen, wobei die Einsatzleitzentrale dazu ausgebildet ist, die empfangenen Positionsdaten laufend an die Verkehrsrechnerzentrale weiterzuleiten, und wobei die Verkehrsrechnerzentrale dazu ausgebildet ist, in Abhängigkeit des aktuellen Standortes des Einsatzfahrzeuges vor Erreichen eines Knotenpunktes die identifizierte Freigabephase anzuschalten und nach Verlassen des Knotenpunktes auf einen regulären Signalplan zurückzuschalten. Durch die fortlaufende Übertragung der in der Einsatzleitzentrale vom Fahrzeuggerät empfangenen Positionsdaten an die Verkehrsleitzentrale können von dort aus zeitgerecht die Freigabephasen an den Lichtsignalanlagen der jeweils angefahrenen Knotenpunkte aktiviert und nach Überfahren des Knotenpunktes wieder deaktiviert werden. Hierdurch kann die durch Anschalten einer Freigabephase hervorgerufene Beeinträchtigung des Verkehrs an dem Knotenpunkt gering gehalten werden, indem baldmöglichst wieder zum regulär ablaufenden Signalplan zurückgeschaltet wird. Die Deaktivierung der angeschalteten Freigabephase kann auch durch die Passage des letzten Einsatzfahrzeuges eines Konvois von Einsatzfahrzeugen erfolgen.In a preferred embodiment of the traffic control system according to the invention, the vehicle device is designed to continuously determine the current location of the emergency vehicle and to transfer the position data describing the particular location to the mission control center, wherein the emergency control center is adapted to continuously forward the received position data to the traffic control center, and wherein the traffic control center is adapted to turn on depending on the current location of the emergency vehicle before reaching a node, the identified release phase and switch back after leaving the node to a regular signal plan. Due to the continuous transmission of the position data received from the vehicle device in the application control center the traffic control center can be timely activated from there the release phases at the traffic lights of each approached nodes and deactivated after crossing the node again. In this way, caused by turning on a release phase impairment of traffic at the node can be kept low by switching back as soon as possible to the regular expiring signal plan. The deactivation of the activated release phase can also be done by the passage of the last emergency vehicle of a convoy of emergency vehicles.
