Abstract

Immer häufiger werden Informationssysteme beim Fahren eingesetzt. Diese dienen dazu dem Fahrer zu assis­tieren, können jedoch auch eine Quelle kognitiver Be­lastung darstellen. Aus diesem Grund wurde eine Nutzerstudie durchgeführt, die es ermöglichen soll, Fahrerassistenzsysteme anzupassen, sodass die Fahraufgabe optimal bewältigt werden kann. Zu diesem Zweck wurden Smartphone-Sensordaten, situative Faktoren sowie Nutzereigenschaften erhoben und untersucht. Die Ergebnisse der Nutzerstudie zeigen auf, dass die Fahrsituation, das Geschlecht sowie die Fahrhäufigkeit einen signifikanten Einfluss auf den Workload haben. Werden diese Daten zusätzlich zu den Smartphone-Sensordaten verwendet, um den Workload vorherzusagen, kann dieser unter Verwendung eines Entscheidungsbaumes mit bis zu 86 Prozent Genauigkeit vorhergesagt werden.
