Abstract
This driving simulator study focuses on false and missing alarms produced by a forward collision warning system and estimates the effect of alarm timing on driver response to alarm malfunction from the perspective of driver trust. The results show that drivers who experience late alarms are reluctant to respond to a false alarm and are not influenced by a missing alarm, however drivers who experience early alarms tend to respond to a false alarm and suffer a delayed response to critical situations following a missing alarm. Furthermore, drivers whose judgement of trust is relatively high, tend to exhibit delayed braking, compared with drivers who have lower levels of trust. These results suggest that driver behaviour towards false and missing alarms may vary according to alarm timing and its influence on trust in alarms, moreover there is a possibility that the negative effects of alarm malfunction may be mitigated by manipulating alarm timing.
