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.

项目概要 虽然对于所有使用手机的驾驶员来说，机动车碰撞风险要高出 2-6 倍，但同时使用手机 驾驶在年轻驾驶员（18-24 岁）中最为普遍。年轻驾驶员的手机使用率最高。 驾驶时的人均车祸率是所有年龄段中最高的，但他们对技术的研究不足。 解决方案，包括手机拦截应用程序和驾驶模式（例如苹果的“驾驶时请勿打扰”）， 可能很有希望，但对有效性的研究仍然很少。我们的试点 R21 发现商业应用程序是有限的。 有效减少驾驶时使用手机，但没有足够的能力来检查高风险驾驶事件。 很少有研究考察驾驶模式或将驾驶模式与商业应用程序在减少手机使用方面进行比较 因此，我们提出了 R01，其目标是进行随机化。 对照试验以确定手机应用程序和驾驶模式干预对减少 18-24 岁司机的手机使用和高风险驾驶事件 如果手机应用程序或驾驶模式处于活动状态，高风险驾驶事件也可以大大减少。 预计驾驶模式与应用程序一样有效。该项目的目的是评估效果。 电话应用程序和驾驶模式干预措施减少打电话、发短信和手持电话的使用（主要 目标 1)，确定手机应用程序和驾驶模式干预措施在减少高风险驾驶方面的效果 事件（主要目标 2），并试点测试使用现有技术跟踪交通违规和碰撞事故的可行性 将进行一项前瞻性、随机、平行组、三臂试验。 总共 1,200 名年轻驾驶员将被随机接收：(1) 一个商业应用程序（活跃的 FleetSafer），该应用程序可以阻止 驾驶时使用手持电话，但允许紧急呼叫和按乘客后使用电话 (2) 阻止手持的驾驶模式（由手机制造商或服务提供商提供） 驾驶时使用电话，但允许紧急呼叫和手动覆盖或 (3) 不活动的 FleetSafer 应用程序 允许并跟踪通话和短信（对照）。参与者将接受为期六个月的研究（第 1 个月：基线， 第 2-6 个月：干预）结果将包括：(1) 在 FleetSafer 跟踪的驾驶过程中打电话和发短信， (2) 驾驶时使用手持电话以及摄像机捕捉到的高风险驾驶事件。 评估应用程序和驾驶模式干预措施在减少打电话、发短信和高风险方面的有效性 在我们初步的 R21 指导下，这项研究具有创新性，因为我们专注于新技术。 我们将采用经过验证的视频来解决与手机相关的分心驾驶问题。 这项研究旨在识别高风险驾驶事件并评估手机使用的贡献。 意义重大，因为研究结果将提供有关手机拦截应用程序有效性的信息 以及减少青少年和年轻人使用手机和高风险驾驶行为的驾驶模式。
