Abstract
A range of In-Vehicle Information Systems are currently
developed and implemented in trucks to warn drivers about
road dangers and vehicle failures. Systems often make use of
conventional repetitive auditory warnings to catch attention. In
a critical driving situation it might be tempting to use signals
that express very high levels of urgency. However, previous
studies have shown that more urgent alerts can have a negative
impact on the listeners’ affective state. A simulator experiment
was conducted to examine how urgent warnings could impact
the affective state of experienced truck drivers, and their
response performance to an unpredictable situation. As
predicted, the more urgent warning was rated more annoying
and startling. The drivers who received an urgent warning
braked significantly harder to the unpredictable event (a bus
pulling out in front of the truck). The drivers also tended to
brake later after the urgent warning, but no significant effect on
response time or time to collision was found. A concluding
recommendation for future research is to investigate distracting
effects of urgent auditory warnings on less experienced drivers.
