Driver distraction and driver inattention: Definition, relationship and taxonomy

Regan, M. A., Hallett, C., and Gordon, C. P.

The objective of this study was to define driver distraction and driver inattention and propose a taxonomy in which driver distraction is clearly distinguished from other forms of driver inattention. The goal of the taxonomy was to provide a common framework to code driver inattention and to make it possible to more accurately interpret and compare research findings regarding various forms of driver inattention.

Authors suggested that driver inattention was comprised of the following forms of inattention: driver restricted attention, driver mis-prioritized attention, driver neglected attention, driver cursory attention, and driver diverted attention. In addition, they indicated that driver diverted attention (DDA) consisted of two sub-categories: DDA non-driving-related, and DDA driving-related. It was proposed that the use of this taxonomy to code distracted driving crashes could strengthen data collection and provide more efficient ways to compare crash rates associated with different types of distraction.
