Study finds driver distraction lingers almost 30 seconds after text


Staff Report



DAYTON — Groundbreaking research by the AAA Foundation for Traffic Safety reveals that the distraction drivers experience using voice activated technology – or their smartphones – to make a call, change music or send a text can linger for almost 30 seconds after the task is complete.

“This should be a wakeup call to anyone who feels safe texting while sitting at a red light”, says AAA Driving School Operations Manager, Michael Belcuore. “Just because you can hit the gas when the light turns green, doesn’t mean you’re good to go.”

Researchers studying different push to talk technologies found that potentially unsafe levels of mental distraction lasted for as long as 27 seconds after completing a task in the worst-performing systems. And, at the 25 MPH speed limit in the study, drivers traveled the length of nearly three football fields during this time. Using the least distracting systems, drivers still remained impaired for more than 15 seconds.

The researchers discovered the residual effects of mental distraction while comparing the voice activated technology in ten 2015 vehicles and three types of smart phones. The analysis found that all systems studied increased mental distraction to potentially unsafe levels.

Researchers rated driver distraction on a scale of 1-5, with 1 being relatively safe, about equal to listening to the radio, and 5 being highly challenging in such a way as to overload the driver’s attention. The best performing system was the Chevy Equinox with a cognitive distraction rating of 2.4, while the worst performing system was the Mazda 6 with a cognitive distraction rating of 4.6.

The systems that performed best generally had fewer errors, required less time on task and were relatively easy to use.

The researchers also studied voice activated smartphone technology and found that Google Now outperformed Apple Siri and Microsoft Cortana but, they say, all were dangerously distracting with ratings of 3.1, 3.4 and 3.8 respectively.

“Automakers often promote everything their connected cars can do, but this research paints a frightening picture of what drivers can’t do if they use the popular features” says Belcuore. “Hands free does not mean risk free. It’s that simple”.

Dr. David Strayer and Dr. Joel Cooper of the University of Utah conducted the research. A total of 257 drivers ages 21-70 participated in the study of 2015 model-year vehicles, while 65 additional drivers ages 21-68 tested the three phone systems. Over the last two weeks, AAA has shared its findings with policymakers, safety advocates and manufacturers in hopes of improving the safety of future technology.

Established by AAA in 1947, the AAA Foundation for Traffic Safety is a 501(c)(3) not-for-profit, publicly-supported charitable educational and research organization. Dedicated to saving lives and reducing injuries on our roads, the Foundation’s mission is to prevent crashes and save lives through research and education about traffic safety. The Foundation has funded over 200 research projects designed to discover the causes of traffic crashes, prevent them and minimize injuries when they do occur.
