This study investigated the effects of using a cell phone to retrieve and send text messages on the driving performance of young novice drivers.
Young drivers are particularly susceptible to driver distraction and have an increased risk of distraction-related crashes. Distractions from in-vehicle devices, particularly, those that require manual input, are known to cause decrements in driving performance.
Twenty young novice drivers used a cell phone to retrieve and send text messages while driving a simulator.
The amount of time that drivers spent not looking at the road when text messaging was up to approximately 400% greater than that recorded in baseline (notext-messaging) conditions. Furthermore, drivers' variability in lane position increased up to approximately 50%, and missed lane changes increased 140%. There was also an increase of up to approximately 150% in drivers' variability in following distances to lead vehicles.
Previous research has shown that the risk of crashing while dialing a handheld device, such as when text messaging and driving, is more than double that of conversing on a cell phone. The present study has identified the detrimental effects of text messaging on driving performance that may underlie such increased crash risk.
More effective road safety measures are needed to prevent and mitigate the adverse effects on driving performance of using cell phones to retrieve and send text messages.
本研究旨在探讨使用手机收发短信对年轻新手驾驶员驾驶表现的影响。
年轻驾驶员特别容易受到驾驶干扰，并且分心相关事故的风险增加。已知车内设备的干扰，尤其是需要手动输入的干扰，会导致驾驶表现下降。
二十名年轻新手驾驶员在模拟器上驾驶时使用手机收发短信。
驾驶员在发短信时不看路的时间高达基线（不发短信）条件下的约 400%。此外，驾驶员的车道位置变化幅度增加了约 50%，错过车道变换增加了 140%。驾驶员与前车保持的跟车距离变化幅度也增加了约 150%。
先前的研究表明，在手持设备拨号时（例如在收发短信和驾驶时）发生碰撞的风险是使用手机通话时的两倍多。本研究确定了发短信对驾驶表现的不利影响，这可能是增加碰撞风险的原因。
需要采取更有效的道路安全措施，以防止和减轻使用手机收发短信对驾驶表现的不利影响。
