• Abstract:
  To determine how distracted and normal driving differ, this report re-examines ; driving performance data from the advanced collision avoidance system (ACAS) field ; operational test (FOT), a naturalistic driving study (96 drivers, 136,792 miles). ; In terms of overall driving performance statistics, distraction (defined as 4 ; successive video frames where the driver’s head was not oriented to the forward ; scene) had almost no effect, except for decreasing mean throttle opening by 36% and ; mean speed by 6%. No consistent normal/distracted differences were found in the ; parameters that fit the distributions of steering wheel angle, heading, and speed (all ; double exponential) and throttle opening (gamma) for each road type by driver age ; combination. ; In contrast, logistic regression identified other statistics and factors that ; discriminated between normal and distracted driving. They included (a) turn signal ; use and age group for expressways, (b) gender and if the lead vehicle range ; exceeded 60 m for major roads, and (c) lane width, lane offset, and lead vehicle ; velocity for minor roads. ; Finally, in a supplemental analysis, throttle holds (1 - 4 s periods of essentially no ; throttle change suggesting the driver may not be attending to driving) were actually ; more common for normal driving when a single time window (1 s) by threshold change ; combination (4 %) was selected. However, when settings (time windows of 1 – 4 s, ; thresholds of 1 – 4 %) were tailored for each age group by road class combination, ; throttle holds could identify when the driver was distracted.
