Use of Electronic Systems While Driving Increases Cognitive Distraction, Says AAA Study
October 13, 2014 - Emeryville, October 7, 2014 – Talking on a cell phone, checking emails, responding to messages, and other distractions have become common behavior behind the wheel for millions of motorists as more “connected cars,” equipped with wireless Internet access, infotainment systems and digital devices, are now on the roads. Even though many motorists have now opted for the hands-free systems in the belief that they would be safer, many would be surprised to learn that these popular new vehicle features may actually increase mental distraction, according to new research by the AAA Foundation for Traffic Safety
This research can serve as guidance to manufacturers that increasingly market hands-free systems as safety features. The good news for consumers is that it is possible to design hands-free technologies that are less cognitively distracting, according to the research.
“Voice-activated electronic devices require cognitive focus, forcing a driver’s minds to not be fully focused on the road. Drivers may potentially miss stop signs, hit pedestrians and other cars while using voice technologies.” says Cynthia Harris, AAA Northern California spokesperson. “We now understand that current shortcomings in these products, intended as safety features, may unintentionally put drivers at risk.”
AAA urges manufacturers to make hands-free technologies as safe as possible for consumers. While manufacturers continue their efforts to develop and refine systems that reduce distractions, AAA encourages drivers to minimize cognitive distraction by limiting the use of most voice-activated technologies.
Using instrumented test vehicles, heart-rate monitors and other equipment designed to measure reaction times, researchers evaluated and ranked common voice-activated interactions based on the level of cognitive distraction generated. The team used a five-category rating system similar to that used for hurricanes. The results show:
- Category 1-Minor risk: Listening to the radio.
- Category 2- Moderate risk: Talking on a hand-held or hands-free cell phone.
- Category 3- Extensive risk: Use of a speech –to-text system to listen, compose emails or texts.
- Category 4-Highest risk: Use of menu-based systems that rely on voice recognition.
AAA Northern California offers a wide array of automotive, travel, insurance, DMV, financial services and consumer discounts to nearly 4 million members. AAA has been a leader and advocate for the safety and security of all travelers since it was founded more than 114 years ago.
