• Abstract:
  NHTSA’s naturalistic driving study, Motivations for Speeding (Richard et al., 2013), examined motivations and situations conducive to speeding behavior. The study collected data from 88 drivers in Seattle, Washington, and 76 drivers in College Station, Texas, over a 3- to 4-week period to record how fast they drove on different roadways. Personal inventories were also collected from drivers to measure demographic, personality, attitudinal, and risk-taking behaviors. ; Speeding was operationally defined as driving 10 mph or more above the posted speed limit. Free-flow episodes (FFE), defined as driving speeds at or above 5 mph below the posted speed limit, were used as a proxy for opportunity to speed. The units of analysis (UA) in the original study were 30-second driving epochs. The additional analyses conducted for this study used time-series data to redefine the UA for speeding in terms of continuous speeding episodes (SEs).
