Zusammenfassung

In einer gemeinsamen Studie des Landes Oberösterreich und des Bundesministeriums für Verkehr, Innovation und Technologie wurden zwischen September 2005 und August 2006 im Bundesland Oberösterreich bzw.–als Vergleichs-gruppe–in den Bundesländern Steiermark, Kärnten und Salzburg 1.180 LKW- und Buslenker mittels Pupillometrie auf Schläfigkeit getestet.

Die Ergebnisse zeigen folgendes Bild:

  • 30,9 Prozent der Probanden hatten grenzwertige und 22,3 Prozent pathologische Messdaten. 53,2 Prozent der beobachteten Lenker waren damit nicht mehr oder nur mehr bedingt fahrtauglich.

  • Die bedenklichsten Werte wurden zu den Zeiten des chronobiologischen Tiefs (01:00h bis 03:00h bzw. 13:00h bis 15:00h Uhr) ermittelt; zusätzlich wurde erstmal aber auch ein Tief um 11:00 Uhr festgestellt.

  • Buslenker hatten im Allgemeinen bessere Werte als LKW-Fahrer.

  • Jüngere männliche Fahrer waren im Durchschnitt müder als das Vergleichskollektiv.

  • Die Nationalität spielte keine Rolle. In- und ausländische Fahrer waren gleichermaßen von Müdigkeit betroffen.

  • Es wurde ein eigener „Pausenfaktor“ entwickelt, um die Relation zwischen gesamter Fahrtdauer und Dauer der Pausen besser darstellen zu können.
