The hazard perception test developed by Sagberg and Bjornskau 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.
