The aim of the present study was to evaluate a method for assessment of drivers’ gaze behaviour and to study gaze and driving behaviour at cycle crossings after right turns. Twenty-one participants were equipped with a head-mounted eye tracking system and were instructed to drive along a predetermined test route in an urban area, in daylight and at night. Five cycle crossings after right turn were passed. At the last cycle crossing during the second driving session, a cyclist was approaching the crossing. After each driving session, the participants filled in a questionnaire. Gaze behaviour just before and at the cycle crossing was analyzed. The participants tended to look towards the cycle path more in daylight than at night. When a cyclist was approaching the crossing, the participants looked at her earlier in daylight than at night. Using a head-mounted eye tracking system worked well for analysis of gaze behaviour towards well-defined objects. The system worked well in daylight as well as at night. A disadvantage is that the system reduces the drivers’ ability to turn their head.
