TL;DR: The results show that crash causation has shifted dramatically in recent years, with driver-related factors present in almost 90% of crashes, and definitively show that distraction is detrimental to driver safety, with handheld electronic devices having high use rates and risk.

TL;DR: In this article, the authors evaluated the use of near crashes as a surrogate measure for assessment of the safety impact of driver behaviors and other risk factors, and concluded that using near crash as a crash surrogate provides definite benefit when naturalistic studies are not large enough to generate sufficient numbers of crashes for statistical analysis.

TL;DR: Results indicate that when drivers are provided with salient visual information regarding safe headways, they utilize the information and increase their headway when appropriate, and a study to investigate the long term effects of such displays on behavior is strongly recommended prior to mass marketing of headway maintenance/collision warning devices.

TL;DR: This study investigated the effects of distraction from the use of three types of cell phones: (1) hand-held (HH), (2) portable handsfree (PHF), and (3) integrated hands-free (IHF), making this the first NDS to date to combine call and text records with continuous naturalistic driving data.

TL;DR: Teenaged, young adult drivers and senior drivers are more adversely impacted by secondary-task engagement than middle-aged drivers, whereas cognitive distraction may have a larger impact on young drivers.
