Which Visual Cues do Drivers Use to Anticipate and Slow Down in Freeway Curve Approach? An Eye-Tracking and Think-Aloud On-road Study - Dataset

An on road experiment was conducted in which 31 participants drove through six freeway curves in their own car. During the experiment, look-ahead fixations and speed were recorded using an eye-tracker and a GPS tracker, respectively. In addition to these measurements, the participants verbalised their reasons for changing speed.  The collected data is shared here: - GPS data of the researched sections - Filtered Eye-tracking data, containing the fixations, timestamps and AoI labels - Verbalisations - 6 muted video’s of the HD-camera from the eye-tracker, containing fixation data (a video for each curve, from a single participant) - Output from the questionnaires More backgrounds can be read in: Vos, J., de Winter, J., Farah, H., & Hagenzieker, M.
