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 <br> More backgrounds can be read in: Vos, J., de Winter, J., Farah, H., &amp; Hagenzieker, M.

本研究开展了一项道路实车实验，共有31名参与者驾驶自有车辆通过6段高速公路弯道。实验过程中，分别通过眼动追踪仪（eye-tracker）与GPS追踪器（GPS tracker）记录了参与者的前瞻注视点与行驶车速。此外，同步收集了参与者出声表述的变速原因相关数据。本次公开共享的采集数据包括：
- 研究路段的GPS数据
- 经滤波处理的眼动追踪数据，包含注视点、时间戳与感兴趣区域（Area of Interest, AoI）标签
- 出声表述的变速原因文本数据
- 6段来自眼动追踪设备高清摄像头的静音视频，每段对应一个弯道，仅包含单名参与者的注视点相关画面
- 问卷调研结果输出文件
