Description

Die Erfindung betrifft ein Wartezeitvorhersagesystem gemäß dem Oberbegriff des Anspruchs 1. Zur Visualisierung der Wartezeit an einer Haltestelle bis zum Eintreffen des nächsten Fahrzeuges, insbesondere eines Busses oder einer Straßenbahn des öffentlichen Personennahverkehrs, wird üblicherweise der momentane Abstand des Fahrzeuges von der Haltestelle zugrunde gelegt. Dabei können auch die tatsächlichen Fahrzeiten unmittelbar vorher von dieser Position zur Haltestelle gefahrener Fahrzeuge berücksichtigt werden. Dem Fahrgast wird dadurch auch bei Verkehrsstockungen eine realistische Wartezeit bis zum Eintreffen des Fahrzeuges signalisiert. Bekannt sind bisher nur Wartzeitvorhersagesysteme, die in ein RBL-System (Rechnergestütztes Betriebs-Leitsystem) integriert sind. Derartige RBL-Systeme sind überaus komplexe und teure vielkomponentige Systeme.The invention relates to a waiting time prediction system according to the Preamble of Claim 1. To visualize the waiting time at a Stop until the next vehicle arrives, especially one Bus or a tram of local public transport Usually the current distance of the vehicle from the stop based on. The actual travel times can also be used vehicles driven from this position to the stop immediately beforehand be taken into account. The passenger is also at Traffic congestion a realistic waiting time until the arrival of the Signaled vehicle. So far only waiting time prediction systems are known, which are integrated in an RBL system (computer-aided operating control system). Such RBL systems are extremely complex and expensive multi-component Systems.

Der Erfindung liegt die Aufgabe zugrunde, ein Wartezeitvorhersagesystem der gattungsgemäßen Art anzugeben, das sich durch eine Minimierung des Hardware-/Software-Aufwandes auszeichnet.The invention has for its object a waiting time prediction system of the generic type to indicate that by minimizing the Hardware / software effort.

Erfindungsgemäß wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Die Lösung basiert auf dem prinzipiellen Ansatz, daß an sich nur eine Positionsbestimmung der Fahrzeuge, eine Fahrzeitabschätzung von dieser Position bis zur Haltestelle mittels eines Rechners und Informationsübertragungsmittel vom Fahrzeug zum Rechner und vom Rechner zum Haltestellendisplay erforderlich sind. Dadurch ergibt sich eine Reduktion auf die nötigsten Baugruppen. Die vorgeschlagene Komplettlösung ist außerdem durch ein gutes Preis-/Leistungs-Verhältnis bei niedrigen Installationszeiten und lnbetriebnahmezeiten gekennzeichnet. Der Aufwand für Hardware-/und Software-Komponenten ist gegenüber der RBL-Variante erheblich verringert.According to the invention, this object is achieved with the characteristic features of claim 1 solved. The solution is based on the principle approach, that in itself only a position determination of the vehicles, a Estimated travel time from this position to the stop using a Computer and means of information transfer from the vehicle to the computer and from the computer to the stop display are required. This gives a reduction to the most necessary assemblies. The proposed one Complete solution is also due to a good price / performance ratio low installation times and start-up times. Of the Compared to the hardware and software components RBL variant significantly reduced.

Die erste Einrichtung zur Ermittlung von Positionsdaten kann gemäß Anspruch 2 funktechnische Mittel, insbesondere Positionsbaken umfassen. Auf diese Weise ergibt sich eine einfache und preisgünstige Positionsbestimmung der Fahrzeuge. Um zu große Abstände zwischen den Meßpunkten zu vermeiden, ist allerdings ein sehr dichtes Netz von Funkbaken erforderlich.The first device for determining position data can be according to Claim 2 include radio means, in particular position beacons. This results in a simple and inexpensive Positioning of the vehicles. To keep the gaps between the Avoiding measuring points is a very dense network of Radio beacons required.

Weit verbreitet zur Positionsbestimmung sind auch im Fahrzeug angeordnete GPS-Empfänger (Global Positioning System) gemäß Anspruch 3. Vorteilhaft bei einer derartigen satellitengestützten Positionserfassung sind vor allem die Unabhängigkeit von weiteren Meßvorrichtungen und die Kontinuität der Meßwerterfassung. Lediglich bei Fahrtroutenabschnitten, bei denen das GPS-Signal abgeschirmt ist, insbesondere in Tunnels und Unterführungen, müssen Meßwertunterbrechungen inkauf genommen werden. In diesem Fall können jedoch andere Systeme, beispielsweise odometrische Meßverfahren, die die Radachsenumdrehungen erfassen, mit dem GPS kombiniert werden.Are also widely used for determining position in vehicles arranged GPS receiver (Global Positioning System) according to claim 3. Advantageous with such a satellite-based position detection are above all the independence from other measuring devices and the Continuity of data acquisition. Only for route sections, at where the GPS signal is shielded, especially in tunnels and Underpasses, measurement interruptions must be accepted become. In this case, however, other systems, for example odometric measuring methods that record the wheel axis revolutions with combined with the GPS.

Zur Erhöhung der Genauigkeit der Positionserfassung kann vorteilhaft gemäß Anspruch 4 ein DGPS (Differencial Global Positioning System) verwendet werden. Dazu ist ein Referenz-Empfänger in einer ortsfesten Zentrale angeordnet. Der Referenz-Empfänger kann aufgrund seines genau bekannten Standortes als Vergleichsnormal für alle im Einsatz befindlichen Fahrzeuge verwendet werden. Die im Fahrzeug gemessenen GPS-Daten werden mit den GPS-Daten des Referenz-Empfängers verglichen, woraus sich ein Korrekturwert ergibt, mit dem die Meßdaten des Fahrzeuges beaufschlagt werden.To increase the accuracy of position detection can be advantageous a DGPS (Differential Global Positioning System) be used. To do this, a reference receiver is in a fixed position Headquarters arranged. The reference receiver can be accurate because of its known location as a standard for all those in use Vehicles are used. The GPS data measured in the vehicle are compared with the GPS data of the reference receiver, from which there is a correction value with which the measurement data of the vehicle be charged.

Neben der ersten Einrichtung zur Positionsdatenermittlung des Fahrzeugs ist zur Wartezeitvorhersage eine zweite Einrichtung zur Berechnung der zu erwartenden , verbleibenden Fahrzeit bis zum Eintreffen des Fahrzeuges an der Haltestelle erforderlich. Diese zweite Einrichtung, die lediglich als Differenzbilder ausgebildet zu sein braucht, kann entsprechend Anspruch 5 im Fahrzeug angeordnet sein. Allerdings muß diese zweite Einrichtung Übertragungsmittel aufweisen, durch die die ermittelte Restfahrzeit an die nächste(n) Haltestelle(n) übertragen werden.In addition to the first device for determining the position data of the vehicle a second device for calculating the waiting time prediction expected remaining driving time until the vehicle arrives the stop is required. This second facility, which is simply called Difference images need to be formed, can be according to claim 5 be arranged in the vehicle. However, this second facility must Have transmission means through which the determined remaining driving time to the next stop (s) will be transferred.

Bevorzugt ist die zweite Einrichtung gemäß Anspruch 6 in einer Zentrale angeordnet, von der aus sich in einfacher Weise eine feste Funkverbindung mit den einzelenen Haltestellen einrichten läßt.The second device is preferably in a control center arranged, from which there is a fixed radio connection in a simple manner can be set up with the individual stops.

Bei beiden Ausführungsformen - zweite Einrichtung im Fahrzeug gemäß Anspruch 5 oder zweite Einrichtung in der Zentrale gemäß Anspruch 6 - kann neben der Wartezeitvorhersage, die für den Fahrgast an der Haltestelle bestimmt ist, gemäß Anspruch 7 zusätzlich eine Berechnung der Fahrplankonfomität, die dem Fahrer signalisiert wird, vorgesehen sein. Eine Abweichung vom Fahrplan, Verspätung oder Verfrühung, ergibt sich aus dem direkten Vergleich der ermittelten Positionsdaten und der fahrplanmäßig vorgesehenen Positionsdaten zu diesem Zeitpunkt. Zur permanenten Anzeige der ermittelten Differenz kann z.B. eine analoge Visulalisierung mittels gliedweise bestromter LED-Ketten vorgesehen sein. Dabei werden entsprechend der Größe des generierten Differenzsignals mehr oder weniger LED-Kettenglieder angesteuert, d.h. bestromt.In both embodiments - second device according to the vehicle Claim 5 or second facility in the center according to claim 6 - can, in addition to the waiting time prediction, for the passenger at the Stop is determined, according to claim 7 additionally a calculation of Schedule conformity, which is signaled to the driver, may be provided. A Deviation from the schedule, delay or early results from the direct comparison of the determined position data and the Scheduled position data at this time. For permanent display of the determined difference can e.g. an analog one Visualization by means of link-energized LED chains can be provided. Here, according to the size of the generated difference signal more or less LED chain links controlled, i.e. energized.
