DRIVING EXPERIENCE AND RESPONSE LATENCIES IN HAZARD PERCEPTION

KULJETTAJAN AJOKOKEMUS JA VAARATILANTEIDEN HAVAITSEMINEN

Thirty-six subjects of the same age (median 24 years) but of different driving experience looked at videotaped traffic scenes and estimated risks involved. The subject groups included those with no licence; with little driving experience (under 10 000 km, median 2 700 km); and with moderate driving experience (over 40 000km, median 60 000 km). Due to the fact that subjects with no driving licence were included, "neutral" task was chosen; each subject was given a potentiometer to be turned from the risk minimum to the risk maximum, 145 degrees altogether. The subjects, one from each group in each of the 12 sessions, were instructed to respond to changes in risk as fast as possible. The results showed that even quite simple stimulus changes induced faster reactions among experienced drivers. When reliable differences between groups appeared, the moderately experienced group was always the first to respond, inexperienced one the second, and the no-licence group the last. These results indicate that, with experience at the wheel, drivers learn to identify early relevant cues of potential hazards and to respond to them at shorter latencies even in quite simple situations.
