Abstract (en)

Data are provided at several measurement locations in the traffic network, relating to several time points within a time period extending backwards from the current time. The variations with time of several data detected in the past are used to determine local state data representing the current state of the traffic network. The state of several road sections may be determined e.g. using stationary sensors. An Independent claim is included for an apparatus for performing the method.

Abstract (de)

Eine qualitativ hochwertige Erzeugung von Verkehrsinformationen aus zeitlich und/oder örtlich lückenhaft vorliegenden Meßdaten wird ermöglicht durch eine Vorrichtung und ein Verfahren zur Vervollständigung und/oder Verifizierung von den Zustand eines Verkehrsnetzes betreffenden Daten in einer Verkehrszentrale, wobei zu mehreren Meßorten im Verkehrsnetz mehrere Zeitpunkte innerhalb eines sich ab dem jetzigen Zeitpunkt zeitlich rückwärts erstreckenden Zeitraumes betreffende Meßdaten zum Zustand des Verkehrsnetzes an den Meßorten vorliegen, wobei aus dem zeitlichen Werte-Verlauf mehrerer zu vergangenen Zeitpunkten erfaßter Meßdaten zu einem Meßort auf den aktuellen Zustand des Verkehrsnetzes repräsentierende Ortszustandsdaten zumindest an Orten geschlossen wird, für welche Orte keine Meßdaten vorliegen. <IMAGE>
