In a recent study at VTI the relation between hazard perception in traffic and visual behaviour among older drivers in comparison with a younger age group has been investigated. The purpose of the study was to provide knowledge on which 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. 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. VTI publication N11A-2010, written in English with a Swedish summary
