Abstract or Summary
  • Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency. This study will examine driver behavior in standing queues at signalized intersection approaches with dual left-turn lanes, and determine what impacts distraction and several other independent variables have on the headways of the first five vehicles. Examining an empirical data set of headway measurements and distraction classifications for over 4000 individual vehicles in Oregon, Utah, and Kansas, linear regression methods will be used to create estimates of the effect of seven in-vehicle distraction classifications (cell phone use, eating or smoking, talking to passengers, manipulating the dashboard other distraction, undistracted, or could not determine). Results show that different distractions increase the median headways of drivers from 5% to 19% when compared to an undistracted driver. The implications of these increased headways on start-up lost time and thus efficiency are then examined.
