This research aims to identify the impact of text messaging on simulated driving performance.
In the past decade, a number of on-road, epidemiological, and simulator-based studies reported the negative impact of talking on a cell phone on driving behavior. However, the impact of text messaging on simulated driving performance is still not fully understood.
Forty participants engaged in both a single task (driving) and a dual task (driving and text messaging) in a high-fidelity driving simulator.
Analysis of driving performance revealed that participants in the dual-task condition responded more slowly to the onset of braking lights and showed impairments in forward and lateral control compared with a driving-only condition. Moreover, text-messaging drivers were involved in more crashes than drivers not engaged in text messaging.
Text messaging while driving has a negative impact on simulated driving performance. This negative impact appears to exceed the impact of conversing on a cell phone while driving.
The results increase our understanding of driver distraction and have potential implications for public safety and device development.
本研究旨在确定短信对模拟驾驶表现的影响。
在过去的十年中，一些基于道路、流行病学和模拟器的研究报告称，使用手机通话对驾驶行为有负面影响。然而，短信对模拟驾驶表现的影响仍未被充分理解。
40 名参与者在高保真驾驶模拟器中进行了单任务（驾驶）和双任务（驾驶和短信）。
对驾驶表现的分析表明，与仅驾驶条件相比，在双任务条件下，参与者对制动灯的开启反应更慢，并且在前进和横向控制方面存在障碍。此外，发短信的驾驶员比不发短信的驾驶员更容易发生撞车事故。
开车时发短信对模拟驾驶表现有负面影响。这种负面影响似乎超过了开车时使用手机通话的影响。
研究结果增加了我们对驾驶员分心的理解，并对公共安全和设备开发具有潜在意义。
