Alarm timing, trust and driver expectation for forward collision warning systems
journal contribution
posted on 2006-07-05, 15:18 authored by Genya Abe, John H. RichardsonIn order to improve road safety, automobile manufacturers are now developing Forward Collision Warning Systems (FCWS).
However, there has been insufficient consideration of how drivers may respond to FCWS. This driving simulator study focused on alarm
timing and its impact on driver response to alarm. The experimental investigation considered driver perception of alarm timings and its
influence on trust at three driving speeds (40, 60 and 70 mile/h) and two time headways (1.7 and 2.2 s). The results showed that alarm
effectiveness varied in response to driving conditions. Alarm promptness had a greater influence on ratings of trust than improvements in
braking performance enabled by the alarm system. Moreover, alarms which were presented after braking actions had been initiated were
viewed as late alarms. It is concluded that drivers typically expect alarms to be presented before they initiate braking actions and when
this does not happen driver trust in the system is substantially decreased.
