Abstract [en]

The hazard perception test developed by Sagberg and Bjornskau (2006) measuring reaction times in relation to different hazardous situations in traffic, has been used in the present study to analyze older drivers’ visual behaviour when passing/responding to the test.

The overall objective of this study has been to investigate the relation between hazard perception in traffic and visual behaviour among older drivers in comparison with a younger age group. The purpose of the study was to provide knowledge on what traffic situations that are more difficult for older drivers to interpret or perceive as hazardous. The elderly were expected to have more problems in situations that included objects classified as context hazards. Context hazards consist of objects that are slowly moving on the side of the road, which poses a situation where the driver should be prepared for the potential behaviour of that object.

The study was composed of two groups of drivers, one group of middle-aged drivers, 35-55 years old, and one group of older drivers, 65 years old and above, who performed the hazard perception test wearing an eye tracker. Hazard interpretation level within age group and situation was investigated, and eye movement data analyzed in terms of fixation duration time.

Overall results showed that the older participants had more problems in interpreting situations classified as context hazards as risky, especially context hazards consisting of pedestrians or cyclists. The differences were nevertheless significant. In addition, when investigating total fixation time on the hazard objects, the differences between age groups were shown to be significant for one of the situations consisting of pedestrians, classified as context/hidden hazard. No significant differences between age groups were found in either of the other situations.

The conclusions are that the elderly tentatively should be exposed to context hazards composed by pedestrians or cyclist in future training schemes. Since there were no significant differences between age groups, more research is, however, needed in the area. Also, since the class of context/hidden hazards, which showed significant differences in fixation time between age groups, was composed by only one situation, resembling situations should be investigated in order to verify these differences.
