Abstract
  • The use of in-vehicle technologies, such as mobile phones, while driving has proliferated in recent years. Most notably, drivers are using mobile phones to send and receive text messages while operating a vehicle with increasing frequency. The act of texting while driving poses a significant threat not only to the driver, but also to passengers and adjacent road users. Texting requires the driver to take at least one hand off the wheel (motor distraction), their eyes off the roadway (visual distraction), and to read messages or conceive of responses (cognitive distraction) all of which can result in the performance degradation of the driving task. This research evaluated the effects of texting while driving, with particular focus on horizontal curves. The OSU Driving Simulator was used to record the lateral position of the vehicle and the glance patterns of the driver. Eighteen subjects drove an experimental course that included four billboards located at the beginning of horizontal curves and were asked to text the name of the animal whose picture appeared on each billboard. Driver glances at the mobile phone and the vehicle’s corresponding lateral position were analyzed to determine their effects on the driving task. This study found that the deviation of lateral position increased for drivers who texted, and the longest single glances away from the road exceed 2.0 seconds in duration which is of critical concern since it is generally accepted that crash risk increases when glances exceed two seconds.
