Definitions
- the invention relates to a method for controlling at least one stop display according to the preamble of claim 1 and a control center according to the preamble of claim 2.
- US 4,799,162 discloses a method in which expected travel times of regular buses depending on previous actual travel times become. These travel times are weighted according to their age, i.e. ever The more up-to-date the previous journey time, the more weight you will have with the Determination of the expected travel time of a bus granted. However, it does there is no change in the weighting due to changing traffic conditions.
- the invention has for its object a method of the generic type indicate a faster response to changes in an identified trend allowed.
- this object is achieved with the characterizing features of Claim 1 solved.
- the solution is based on the principle approach, not just that Position dependency, but also the actual travel times immediately beforehand vehicles driven from this position to the stop.
- the passenger is realistic in traffic congestion Waiting time until the vehicle arrives is signaled.
- the passenger can rely on the displayed waiting time, so that ultimately also an improvement in Ease of use and thus the acceptance of local public transport is achieved.
- a constant trend for example with a steady increase in travel time, as many vehicles as possible are taken into account, for example at Trend weakening or trend reversal of fewer vehicles in the forecast be included. This way, a quick adjustment to the actual traffic conditions possible.
- Claim 2 relates to a control center for calculating the travel time on a Stretch.
- a comparison of the actual travel times is most recent this route section of vehicles driven and a derivative of one mathematical series provided in the form of a trend line.
- the selection circuit determines the number of series elements, with one difference of the last measured value outside of a predetermined range of variation Reduction of the number of row elements to be considered leads. In the case, that a trend reversal is detected, i.e. that instead of an increase in travel time a reduction in travel time for a certain section of the route takes place, the number of measured values for the series formation on one or two be reduced.
- Such a control center can be part of a traffic control system.
- Traffic control system is here in the broadest sense a monitoring and control system for to understand every vehicle fleet. For example, that would be conceivable Traffic management of a truck fleet, whereby the possibility arises here with a pronounced trend line towards traffic congestion to traffic jam accordingly specify adapted, changed travel routes and travel times. So flexible Route and times can also be advantageous for bus control systems.
- the activation of one Stop displays to signal the expected waiting time for the potential passenger.
- Another possible application of the claimed control center results from the statistical evaluation of the Measured values over a longer period of time to get a realistic timetable for a certain route, which consists of evaluated route sections composed to derive.

Claims (4)
- Verfahren zur Ansteuerung mindestens eines Haltestellen-Displays (1), bei dem ein Fahrzeug (2) die aktuelle Position (x1) an eine Steuerzentrale übermittelt, welche die voraussichtliche Wartezeit (tw) bis zum Eintreffen des Fahrzeugs (2) an der Haltestelle (x2) berechnet, und das Haltestellen-Display (1) zur visuellen Signalisierung dieser Wartezeit (tw) ansteuert, wobei die Wartezeit (tw) in Abhängigkeit von einem Trend der tatsächlichen Fahrzeiten (t1, t2,...tm, tm+1,...tn) einer Anzahl (n) unmittelbar vorhergefahrener Fahrzeuge (3, 4,...) berechnet wird, dadurch gekennzeichnet, daß die Anzahl (n) der zu berücksichtigenden Fahrzeuge (3, 4...) bei sich änderndem Trend verringert wird.
- Steuerzentrale mit einem Rechner zur Berechnung der voraussichtlichen Fahrzeit (tf) eines Fahrzeugs (2) auf einem zwischen zwei Positionen (xi und xi+1) definierten Streckenabschnitt, wobei der Rechner Speichermittel zur Speicherung der tatsächlichen Fahrzeiten (tf1, tf2,..., tfN) einer maximalen Anzahl (N) unmittelbar vorher auf dem Streckenabschnitt gefahrenen Fahrzeuge (3, 4 ...) und Vergleichsmittel zur Ermittlung einer Trendlinie einer bestimmten Anzahl (n < N) unmittelbar vorher gefahrener Fahrzeuge (3, 4 ...) sowie Auswertemittel zur trendlinienabhängigen Berechnung der voraussichtlichen Fahrzeit (tf) des Fahrzeugs (2) aufweist, dadurch gekennzeichnet, daß die Vergleichsmittel eine Auswahlschaltung zur Festlegung der Anzahl (n) der zu berücksichtigenden Fahrzeuge (3, 4...) in Abhängigkeit von der Konstanz der Trendlinie aufweisen.
- Steuerzentrale nach Anspruch 2, gekennzeichnet durch die Verwendung bei einem Verkehrsleitsystem.
- , Steuerzentrale nach einem der Ansprüche 2 bis 3, gekennzeichnet durch die Verwendung zur Ansteuerung mindestens eines Haltestellen-Displays (1), wobei eine visuelle Signalisierung der voraussichtlichen Wartezeit (tw) bis zum Eintreffen des Fahrzeuges (2) an der Haltestelle (x2) vorgesehen ist.
