US DOT Presents Studies Regarding Distracted Driving

The US Department of Transportation has information authored by the National Transportation Library, USDOT and it is meant to be background introduction to the existing status of research on this issue of distracted driving, in addition to featuring numerous information from the past 10 years. The Department does not endorse the research listed in this bibliography, nor does any of the studies stand for the official policy or position of the Department of Transportation, its agencies or its employees.

According to the National Highway Traffic Safety Administration (NHTSA) information, the age group with the greatest proportion of distracted drivers was the under-20 age group. Sixteen percent of all under-20 drivers linked to a lethal crash were documented to have been distracted while driving. Of these people involved in deadly crashes who were apparently distracted, the 30-39 year old group had the greatest percentage of cellphone involvement.  The need to trace mobile usage to decrease distracted driver crashes pertains to both parents of kids, as well, companies.

The Driver Electronic Device Use Observation Protocol fact sheet details the standards used by the annual National Occupant Protection Use Survey (NOPUS) to watch drivers who are visibly manipulating hand-held devices (e.g., texting) or are using hand-held mobile phones.  The Research Note, Driver Electronic Use in 2009, offers outcomes with the 2009 National Occupant Protection Use Survey (NOPUS) that demonstrate that percentage of drivers noticeably manipulating hand-held devices while driving dropped significantly from 1.0 percent in 2008 to 0.6 percent in 2009 and the hand-held cell phone use by drivers also fell appreciably from 6 percent in 2008 to 5 percent in 2009.

Grownups are just as probable as teenagers to have texted when driving and are also substantially prone to have talked on the phone while driving.  Moreover, 49% of adults admit they’ve been passengers in a car when the driver was sending or reading text messages on their cellular phone. Overall, 44% of adults assert they have been passengers of drivers which used the cellular phone in a fashion that put themselves or others at risk. Beyond driving, some cell-toting pedestrians get so preoccupied when chatting or texting that they have actually knocked into another person or an object.  Using Cell Phone Spy to observe cell phone usage may possibly pertain to not only distracted drivers.

Driver distraction is a major and tough safety issue to deal with.   The purpose of the present study, Driver distraction in commercial vehicle operations, was to target the gap in research by investigating driver distraction in CMV operations. Naturalistic data collection is a method used to analyze driver actions and efficiency by setting up sensors and video cameras in fleet vehicles and providing these vehicles to truck drivers to use as part of their normal revenue-producing deliveries. Using software to monitor Track Cell Phone may also have other benefits in identifying cell phone misuse.  Taken collectively, these data sets represent 203 CMV drivers, seven trucking fleets, and 16 fleet locations. With regard to information, the data set used involves roughly 3 million miles of constantly gathered kinematic and video data, and represents the most extensive naturalistic CMV driving set in the world.

Analysis of 1995-1999 Crashworthiness Data System (CDS) data, comprising police records of tow-away accidents, attributes 1.5% of crashes to using/dialing a cell phone.  The Role of Driver Distraction in Traffic Crashes authors find no difference in impairment due to hands-free as compared to hand-held cellular phone use, and that the participants in the two mobile phone circumstances were involved in more rear-end collisions and reacted 9% more slowly to vehicles in front when they began to brake. The mean response time difference was 0.07 seconds.

The Examining the Impact of Cell Phone Conversations on Driving Using Meta-Analytic Techniques research synthesis discovers across 28 studies that hands-free and handheld cellphone use both cause sluggish reaction times than without use of these devices. The average difference was 0.13 seconds. The study also examined 19 studies on lane-keeping, but found no effect.
