Abstract
<p>Objective, detailed and accurate information regarding the prevalence of factors with the potential to contribute to crashes is vital. In-vehicle event recorders (IVERs) have become a widely accepted means of gathering crash data both in research and real-world applications. This study examines naturalistic data from crashes that involved teenage drivers aged 16-19 with the use of a Lytx’s DriveCam system. A total of 1,691 moderate-to-severe crashes met the inclusion criteria were analyzed for the current study. Video from the 6 seconds preceding each crash were coded for analysis. The video data were coded with the goal of identifying the factors present prior to crashes – in particular the prevalence of potentially distracting driver behaviors and drowsiness. The study addressed the following research questions: <ol> <li>What were the roadway and environmental conditions at the time of the crash?</li> <li>What were the critical events and potential contributing factors leading up to the crash and did these differ by crash type?</li> <li>What driver behaviors were present in the vehicle prior to the crash and did these differ by crash type?</li> <li>How did driver reaction times and eyes-off-road time differ relative to certain driver behaviors and crash types?</li> <li>Could drowsy driving be detected using this type of crash data?</li> </ol></p>
<p>Understanding the prevalence of potential contributing causes of crashes provides a significant societal benefit and advances the field of traffic safety. More specifically, information regarding what is happening inside the vehicle during the seconds before a crash can suggest countermeasures such as education, training, or advanced safety technologies that might best mitigate certain types of crashes.</p>
