ABSTRACT
The Strategic Highway Research Program 2 (SHRP2) can provide unique information on how driver behavior leads to crashes or near-crashes. A subset of this dataset was created to examine naturalistic engagement in secondary tasks (NEST; Owens, Angell, Hankey, Foley, & Ebe, 2015). The NEST dataset is composed of crash and near-crash epochs which have identified secondary tasks as a contributing factor and contains 20 seconds of coding before a crash or near-crash. The present analysis aims to identify high level prevalence characteristics of the dataset. This analysis focuses on the prevalence of secondary task engagement alone, during adverse weather, and during different traffic densities. Additionally, task occurrence with other tasks (i.e., comorbidity) is considered. Overall, the results indicate that some factors (e.g., weather, traffic density) can influence a driver's decision to engage in certain secondary tasks.

Effects of a Preventive Warning Light System for Near-Miss Incidents
This article describes how the number of fatal traffic accidents has been decreasing in Japan because of recent safety technologies of vehicles, such as stiff cabins, antilock braking systems, and seat belts. Automated vehicles and advanced driver ...
Influence of Nonvisual Secondary Tasks on Driver's Pedestrian Detection
The most frequent type of fatal traffic accident is caused by "aimless driving" in Japan. In many cases the victims are pedestrians on straight roads, where there are usually fewer objects drivers need to pay attention to than at intersections. In this ...
Speech Feedback Reduces Driver Distraction Caused by In-vehicle Visual Interfaces
AM '16: Proceedings of the Audio Mostly 2016Driver distraction and inattention are the main causes of accidents today and one way for vehicle manufacturers to address this problem may be to replace or complement visual information in in-vehicle interfaces with auditory displays. In this paper, we ...
