PROJECT SUMMARY While motor vehicle crash risk is 2-6 times higher for all drivers engaging in cellphone use, cellphone use while driving is most prevalent among young drivers (18-24 years). Young drivers have both the highest phone use while driving and the highest crash rate per capita among all ages, but they are understudied. Technological solutions, including cellphone-blocking apps and driving mode (e.g., Apple’s “Do Not Disturb While Driving”), may be promising, but research on effectiveness remains sparse. Our pilot R21 found that a commercial app is effective in reducing cellphone use while driving, but had insufficient power to examine high-risk driving events. Few studies have examined driving mode or compared driving mode with a commercial app in reducing phone use and high-risk driving events. Therefore, we propose an R01 with objective to conduct a randomized controlled trial to determine the effects of a cellphone app and a driving mode intervention in reducing cellphone use and high-risk driving events in drivers aged 18-24 years. We hypothesize that cellphone use and high-risk driving events can be substantially reduced if a cellphone app or driving mode is active. We also hypothesize that the driving mode is as effective as the app. The aims of this project are to estimate the effects of the phone app and driving mode interventions in reducing calling, texting, and handheld phone use (Primary Aim 1), determine the effects of the phone app and driving mode interventions in reducing high-risk driving events (Primary Aim 2), and pilot test the feasibility of tracking traffic violations and crashes using existing databases (Exploratory Aim 3). A prospective, randomized, parallel-group, three-arm trial will be conducted. A total of 1,200 young drivers will be randomized to receive: (1) a commercial app (active FleetSafer) that blocks handheld phone use while driving, but allows emergency calls and phone use after pressing the passenger button; (2) a driving mode (provided by the cellphone manufacturer or service provider) that blocks handheld phone use while driving, but allows emergency calls and manual override or (3) an inactive FleetSafer app that permits and tracks calls and texts (controls). Participants will be studied for six months (month 1: baseline, month 2-6: intervention). The outcomes will include: (1) calling and texting while driving tracked by FleetSafer, and (2) handheld phone use while driving and high-risk driving events captured by a video camera. We will estimate the effectiveness of the app and driving mode interventions in reducing calling, texting, and high-risk driving events. Guided by our preliminary R21, this study is innovative as we focus on novel technological approaches to address the epidemic of cellphone-related distracted driving. We will employ proven video capture methods to identify high-risk driving events and assess the contribution of cellphone use. This study is significant, because the findings will provide information regarding the effectiveness of cellphone-blocking apps and driving modes in reducing cellphone use and high-risk driving behaviors in teens and young adults.

项目摘要 尽管使用手机使用手机的所有驾驶员的机动车撞车风险是使用手机的2-6倍 在年轻的驾驶员中，驾驶最普遍（18 - 24年）。年轻司机的手机使用最高 在驾驶和所有年龄段的人均崩溃率最高的同时，但它们被理解。技术 解决方案，包括手机障碍应用程序和驾驶模式（例如，苹果的“开车时不要打扰”）， 可能是有希望的，但是对有效性的研究仍然很少。我们的飞行员R21发现商业应用程序是 有效地减少驾驶时使用手机的使用，但没有足够的功率检查高风险驾驶事件。 很少有研究检查驾驶模式或将驾驶模式与商业应用进行比较，以减少手机 使用和高风险驾驶活动。因此，我们提出一个具有客观进行随机的R01 对照试验确定手机应用程序的影响和驾驶模式干预措施减少 18-24岁的驾驶员的手机使用和高风险驾驶事件。我们假设手机使用和 如果手机应用程序或驾驶模式处于活动状态，则可以大大减少高风险驾驶事件。我们也是 假设驾驶模式与应用程序一样有效。该项目的目的是估计效果 手机应用程序和驾驶模式干预措施，以减少呼叫，发短信和手持电话使用（主要 AIM 1），确定电话应用程序的影响和驾驶模式干预措施在减少高风险驾驶中 事件（主要目标2），并试点测试使用现有的违规交通违规和崩溃的可行性 数据库（探索目的3）。将进行一项前瞻性，随机，平行组，三臂试验。一个 总共有1,200名年轻驾驶员将被随机接收：（1）封锁的商业应用程序（Active Fleetsafer） 开车时使用手持电话，但按下乘客后允许紧急电话和电话使用 按钮; （2）驱动模式（由手机制造商或服务提供商提供），该模式阻止了手持 开车时使用电话，但允许紧急呼叫和手动覆盖或（3）一个不活动的舰队宣布应用程序 允许并跟踪呼叫和文本（控件）。参与者将研究六个月（第1个月：基线， 2-6月：干预）。结果将包括：（1）在由Fleetsafer跟踪的驾驶时打电话和发短信， （2）驾驶时使用手持电话以及由摄像机捕获的高风险驾驶事件。我们将 估计应用程序和驾驶模式干预措施在减少呼叫，发短信和高风险方面的有效性 驾驶活动。在我们的初步R21的指导下，这项研究具有创新性，因为我们专注于新颖的技术 解决与手机相关的分心驾驶流行的方法。我们将采用证明视频 捕获识别高风险驾驶事件并评估手机使用的贡献的方法。这项研究是 重要的是，因为这些发现将提供有关手机障碍应用程序有效性的信息 以及减少青少年和年轻人的手机使用和高风险驾驶行为方面的驾驶模式。
