SUMMARY:Effects of Time Headway on Driving after Prolonged Automation Expo
 sure: Evidence for Behavioral Adaptation
DESCRIPTION:LeGrand Dudley and Patricia DeLucia (Rice University)\n\nWhen 
 the control of a vehicle changes from manual to automated, a driver’s role
  changes from an active operator to a passive supervisor who monitors the 
 automated vehicle (AV). This can result in adverse behavioral adaptation e
 ffects (BAEs). For example, prior studies showed that after being exposed 
 to an AV that adopts an extremely small time headway for a prolonged durat
 ion, drivers may adopt a shorter time headway than what they would normall
 y adopt after they take over manual control. However, the effect of an AV’
 s headway on BAEs has not been examined. The current study conducted two e
 xperiments to determine whether a) the effect of exposure duration (15, 25
  minutes) on a driver’s headway post-automation depends on the AV’s headwa
 y during automation (0.3s, 0.6s), and b) a driver’s trust in the AV varies
  with the AV’s headway (0.3s, 0.6s, 1.5s). Results revealed that trust was
  positively correlated with AV headway. Furthermore, a significant number 
 of drivers reduced their headways after regaining control of the vehicle, 
 a result consistent with prior BAE research. Future research is needed to 
 investigate how long drivers maintain their reduced headways after regaini
 ng control.\n\n
