Summary
This study addresses the persistent road safety issue of smartphone-related distracted driving, specifically focusing on the low adoption rates of built-in "Do Not Disturb" (DND) features on Android and iOS devices. Despite the availability of these countermeasures, most drivers rarely use them. The research aimed to identify barriers to DND usage and determine if educational interventions could improve driver awareness and subsequent behavior. The investigation employed a three-part methodology. Part I involved a literature review of 32 articles to characterize drivers prone to smartphone use. Part II utilized an online survey of 300 licensed drivers (mean age 33.6) to assess perceptions, knowledge, and barriers regarding DND features, categorizing participants as current, non-, or previous users. Part III was an on-road naturalistic study involving 26 participants (mean age 21) whose vehicles were instrumented for 10 weeks. The first five weeks served as a baseline with no intervention, followed by training on DND functionality and a requirement to activate the feature for the remaining five weeks. Smartphone behavior was monitored via the DriveWell Go™ app. The literature review indicated that younger drivers (18–24) and those with less experience are more likely to use smartphones while driving. Survey results revealed significant misconceptions among drivers; many avoided DND because they believed it blocked music and navigation apps, which it does not. Additionally, 60% of previous users cited forgetting to activate the feature, while 32% of non-users were unaware of its existence. Younger drivers were more knowledgeable about DND but also more likely to discontinue use, often believing they could drive safely while messaging. In the naturalistic study, pre-training knowledge accuracy ranged from 50% to 85%, but post-training, all participants reported understanding how to use and auto-activate DND. Although opinions on DND did not change, behavioral data showed a 41% decrease in the odds of smartphone tasks after DND activation. Participants were also 6% less likely to pick up their phones. However, a small subset (5%) showed increased tapping events, likely due to the steps required to disengage DND to unlock the phone. The findings suggest that DND is effective in reducing smartphone interactions when activated, but usage is hindered by lack of awareness and functional misconceptions. The study concludes that targeted training can improve knowledge and automatic activation rates. To further increase adoption, the authors recommend design improvements such as contextual awareness for automatic activation during stressful driving conditions, better accuracy in distinguishing drivers from passengers, and greater user control over restricted apps.
Key finding
Activating Do Not Disturb features significantly reduced smartphone interactions while driving, with a 41% decrease in the odds of smartphone tasks and a 6% reduction in phone pickups, although educational training alone did not alter participants' opinions of the feature.
