Conference paper


This study mainly forcused on unnecessary alarms for forward collision warning systems (FCWS) and two driving simulator experiments were conducted to investigate whether considering individual driving characteristics is reasonable for decreases in unnecessary alarms when determining alarm timing. The results indicate that if the average characteristics of car-following behaviour are taken into account when determining alarm timing, unnecessary alarms are not a problem except for drivers who tend to follow a lead vehicle with the short distance between vehicles. Alarm timing based on the particular characteristics of individual car-following behaviour thus has the potential to further decrease unnecessary alarms, independent of driving speed.
