Abstract

Die Erfindung betrifft ein Verfahren zur Erfassung des Verkehrszustandes an einem lichtsignalgesteuerten Knotenpunkt eines Straßennetzes, dem sich Fahrzeuge (F) auf einer Fahrspur (L) nähern. Es werden Belegungszeiten (tb) eines der Fahrspur (L1, L2) zugeordneten Fahrzeugdetektors (Dl, D2) gemessen. Es werden ferner sich abwechselnde Sperr- und Freigabezeiten (tS, tF) eines der Fahrspur (L1, L2) zugeordneten Signalgebers (S1, S2) einer Lichtsignalanlage gemessen. Es wird dann eine Füllzeit ab Beginn einer Sperrzeit (tS) bis zu einer Dauerbelegung des Fahrzeugdetektors (Dl, D2) gemessen. Die Füllzeit wird mit einer vorgebbaren Referenzfüllzeit verglichen. Der Verkehrszustand wird als nicht überlastet gewertet, solange die Referenzfüllzeit überschritten wird, andernfalls wird der Verkehrszustand als überlastet gewertet. Erfindungsgemäß wird bei unterschrittener Referenzfüllzeit wenigstens ein Ausschlusskriterium geprüft, wobei die Wertung des Verkehrszustandes in nicht überlastet abgeändert wird, wenn das Ausschlusskriterium zutrifft, andernfalls die Wertung des Verkehrszustandes als überlastet bestätigt wird. Hierdurch wird die automatisierte Erfassung des Verkehrszustandes an dem lichtsignalgesteuerten Knotenpunkt verbessert.

The invention relates to a method for detecting the traffic condition at a light signal-controlled node of a road network, the vehicles (F) on a lane (L) approach. Occupancy times (t b ) of a vehicle detector (D 1, D 2) assigned to the lane (L 1, L 2) are measured. Furthermore, alternating blocking and release times (t S , t F ) of a signal transmitter (S1, S2) of a traffic signal system associated with the traffic lane (L1, L2) are measured. It is then a filling time from the beginning of a blocking time (t S ) measured up to a permanent occupancy of the vehicle detector (Dl, D2). The filling time is compared with a predefinable reference filling time. The traffic condition is considered as not overloaded as long as the reference filling time is exceeded, otherwise the traffic condition is considered as overloaded. According to the invention, at least one exclusion criterion is checked when the reference filling time is exceeded, the rating of the traffic condition being changed to uncontrolled if the exclusion criterion applies, otherwise the rating of the traffic condition is confirmed as being overloaded. This improves the automated detection of the traffic condition at the traffic signal controlled node.
