尽管它的重要性，很少被发现在文献中的视觉任务的行人，特别是在夜间。本研究的目的是确定和验证行人在夜间的主要视觉任务，以及视觉环境中对行人很重要的关键方面。在这项研究中，采用眼动追踪方法。佩戴眼动仪，要求受试者走三条不同的住宅路线（白天5名受试者，晚上15名受试者）。为了获得更多关于受试者在行走过程中的经历的信息，在任务完成后进行了简短的访谈。结果表明，虽然行人可能会花费40%至50%的时间看人行道，但并非所有的时间都花在关键的视觉任务上。看其他人似乎对行人很重要，但在这项研究中，受试者注视其他人的时间是有限的。与人行道上的任务相比，远离人行道的视觉任务的明显重要性提出了关于使用道路和人行道上的照度来指定住宅道路上的照明是否合适的问题。
Despite its importance, very little is found in the literature on the visual tasks of pedestrians, particularly at night. This study was performed to identify and characterise the principal visual tasks of pedestrians at night and the key aspects of the visual environment that are important to pedestrians. In this study, an eye tracking method was employed. Wearing an eye tracker, subjects were asked to walk three different residential routes (5 subjects in day time and 15 subjects at night). In order to obtain further information about the experience of the subjects during the walk, a short interview was performed after completion of the task. The results show that whilst pedestrians may spend between 40% and 50% of their time looking at the footpath, not all of that time is spent on critical visual tasks. Looking at other people appears to be important to pedestrians but during this study the amount of time when subjects fixated on other people was limited. The apparent importance of the visual tasks away from the footpath compared to the tasks on it raises questions about how appropriate it is to specify the lighting on residential road using illuminance on the road and pavement.
