USA: According to new findings from the AAA Foundation for Traffic Safety, hands-free technologies might make it easier for motorists to text, talk on the phone, or even use Facebook while they drive, but dangerous mental distractions exist even when drivers keep their hands on the wheel and their eyes on the road.
The research found that as mental workload and distractions increase reaction time slows, brain function is compromised, drivers scan the road less and miss visual cues, potentially resulting in drivers not seeing items right in front of them including stop signs and pedestrians.
As in news, with a predicted five-fold increase in infotainment systems in new vehicles by 2018, AAA is calling for action as result of this landmark research.
Cognitive distraction expert Dr. David Strayer and his research team at the University of Utah measured brainwaves, eye movement and other metrics to assess what happens to drivers’ mental workload when they attempt to do multiple things at once, building upon decades of research in the aerospace and automotive industries. The research included:
• Cameras mounted inside an instrumented car to track eye and head movement of drivers.
• A Detection-Response-Task device known as the “DRT” was used to record driver reaction time in response to triggers of red and green lights added to their field of vision.
• A special electroencephalographic (EEG)-configured skull cap was used to chart participants’ brain activity so that researchers could determine mental workload.
As per the source, using established research protocols borrowed from aviation psychology and a variety of performance metrics, drivers engaged in common tasks, from listening to an audio book or talking on the phone to listening and responding to voice-activated emails while behind the wheel. Researchers used the results to rate the levels of mental distraction drivers experienced while performing each of the tasks. Similar to the Saffir-Simpson scale used for hurricanes, the levels of mental distraction are represented on a scale:
• Tasks such as listening to the radio ranked as a category “1” level of distraction or a minimal risk.
• Talking on a cell-phone, both handheld and hands-free, resulted in a “2” or a moderate risk.
• Listening and responding to in-vehicle, voice-activated email features increased mental workload and distraction levels of the drivers to a “3” rating or one of extensive risk.
Based on this research, AAA urges the automotive and electronics industries to join in exploring:
• Limiting use of voice-activated technology to core driving-related activities such as climate control, windshield wipers and cruise control, and to ensure these applications do not lead to increased safety risk due to mental distraction while the car is moving.
• Disabling certain functionalities of voice-to-text technologies such as using social media or interacting with e-mail and text messages so that they are inoperable while the vehicle is in motion.
• Educating vehicle owners and mobile device users about the responsible use and safety risks for in-vehicle technologies.
As per the source, AAA also is using the findings to promote dialogue with policy makers, safety advocates and industry to ensure that these emerging in-vehicle technologies won’t lead to unintentional compromises in public safety. As part of this effort, AAA has already met with safety advocates and provided copies of the report to CEOs of all major U.S. automakers.
