Abstract or Summary
  • Red Signal Countdown Timers (RSCTs) are devices placed at intersections to inform drivers of the time remaining on a red indication before it turns green, typically to improve intersection efficiency. This study examines the visual attention of Oregon drivers to circular red (CR) indications with RSCTs as compared to standard CR indications to determine how RSCTs impact intersection safety and efficiency. Second, it examines the variation in driver visual attention according to the duration of the red indication. Average fixation duration (AFD) data for 24 licensed Oregon drivers of varying age and driving experience was collected in a driving simulator experiment, using eye tracking equipment. Participants drove an experimental course of intersections with a combination of standard CR and CR with RSCT indications of 20, 40, and 60-second durations. RSCTs counted down the last 10 seconds of the red phase for each duration of red indication. Results show that the average median AFD of drivers was 0.24 seconds for a standard CR indication and 0.34 seconds for a CR indication with RSCT. There was no statistically significant difference between standard circular red or circular red with RSCT indications of varying duration (p<0.05).
