Management of travelers' cognitive load is crucial for efficient information processing for optimal railway operations. We investigated variations in travelers' cognitive load with different expertise levels, in a field study. We aimed to assess the use of three eye metrics: pupil diameter, saccade amplitude and gaze of fixation duration for cognitive load analysis between expert and novice travelers in a Mass Transit train station: Saint-Michel Notre Dame. Physiological measures of emotional activity through skin conductance responses were also investigated, together with subjective measures of mental load using NASA-Task Load Index. Our results followed our expectations, where novice travelers expressed higher cognitive load than expert travelers, characterized by wider pupil diameter, larger amplitude of saccade and longer gaze duration, as well as higher electrodermal activity and NASA-TLX. Additional observations showed that experts used hierarchical and symmetrical scan paths, with more intense exposure on relevant information, characterized by brighter heat maps. This difference in behavior showed a clear difference in strategies for information retrieval at different expertise levels. Metrics of eye tracking device, together with electrodermal activity, proved to be potent in cognitive load analysis of train travelers, and helped to provide insights for real-life information processing.

旅客认知负荷的管理对于实现最佳铁路运营的有效信息处理至关重要。在一项现场研究中，我们调查了不同专业水平的旅行者认知负担的变化。我们旨在评估三种眼睛指标的使用：瞳孔直径，扫视幅度和注视持续时间的注视，以用于在捷运火车站Saint-Michel Notre Dame中进行专家和新手旅行者之间的认知负荷分析。还研究了通过皮肤电导反应进行的情绪活动的生理指标，以及使用NASA-任务负荷指数对精神负荷的主观测量。我们的结果符合我们的预期，即新手旅行者比专业旅行者表现出更高的认知负荷，其特征在于瞳孔直径更大，扫视幅度更大，凝视时间更长，以及更高的皮肤电活性和NASA-TLX。其他观察结果表明，专家使用分层和对称的扫描路径，对相关信息的曝光更加强烈，其特征在于热图更亮。行为上的这种差异显示了在不同专业水平上信息检索策略的明显差异。事实证明，眼动追踪设备的度量标准以及皮肤电动活动在火车旅客的认知负荷分析中非常有效，并有助于为现实生活中的信息处理提供见识。行为上的这种差异显示了在不同专业水平上信息检索策略的明显差异。事实证明，眼动追踪设备的度量标准以及皮肤电动活动在火车旅客的认知负荷分析中非常有效，并有助于为现实生活中的信息处理提供见识。行为上的这种差异显示了在不同专业水平上信息检索策略的明显差异。事实证明，眼动追踪设备的度量标准以及皮肤电动活动在火车旅客的认知负荷分析中非常有效，并有助于为现实生活中的信息处理提供见识。
