What are Australian drivers doing behind the wheel? An overview of secondary task data from the Australian naturalistic driving Study

Using data from the Australian Naturalistic Driving Study (ANDS), this study examined patterns of secondary task engagement during everyday driving trips to determine the type and duration of secondary task engagement and the number and type of incidents associated with secondary task engagement. Results revealed that driver engagement in secondary tasks is frequent, with drivers engaging in one or more secondary tasks every 1.6 minutes, on average. Many of these secondary tasks involved short, discrete button presses and interactions with vehicle controls that lasted less than 5 seconds total duration.
