Title: Post and During Event Effect of Cell Phone Talking on Driving Performance - A Driving Simulator Study
Abstract: A number of studies have been done in the field of driver distraction, specifically on the use of cell phone for either conversation or texting while driving. However, till now, researchers have focused on the driving performance of drivers when they were actually engaged in the task, i.e. during the texting or phone conversation event. The primary objective of this paper is to analyze the post event effect of cell phone usage in order to verify whether the distracting effect lingers on after the actual event had ceased. It utilizes a driving simulator study of twenty participants to test whether a significant decrease in driver performance occurs during cell phone usage (texting and conversation) and after the usage. Using the standard deviation of lane position and mean velocity to respectively represent lateral and longitudinal control of the vehicle, the results suggest that there was no significant decrease in driver performance during the cell phone conversation. On the contrary, during the texting event, a significant decrease in driver performance was observed in the lateral control of the vehicle, but not in the longitudinal control. The decrease in performance remained significant for an average of 3.35 seconds after the texting event ended. This indicates that the distraction and subsequent elevated crash risk of texting while driving linger on even after the texting event has ceased. Such finding has safety and policy implications in the fight to reduce distracted driving.
