“…The percentages of votes for an image being considered safer are shown in Figure 7: the significance of differences between poses are shown in Table 5, these being determined using Dunn-Rankin Variance Stable Rank Sums (VSRS). 37 Face concealment shows a gradual reduction in votes for being the safer situation as the face changes from fully exposed (84%) to fully concealed (15%) (Figure 7). The Dunn-Rankin test did not suggest significant difference between (pose 3) top-concealed and (pose 2) bottom-concealed faces, but differences between the other poses (1 vs 2, 1 vs 3, 1 vs 4, 2 vs 4, 3 vs 4) were suggested to be significant ( p < 0.01) (Table 5).…”

Pedestrians need to be able to evaluate other people to support their feeling of safety. While past studies have thus investigated the degree to which road lighting supports facial identity and facial emotion evaluations, it is not yet known whether the face is the most important visual cue. Following a pilot study that indicated the importance of the ability to see the face and hands of other people, an experiment was conducted in which test participants evaluated safety when shown photographs of an approaching person in night-time scenes. These photographs displayed variations in the exposure or concealment of the face and hands. Two procedures were used, category rating and paired comparisons. The results suggest that the face is a more important visual cue than the hands for pedestrians’ evaluations of the intent of other pedestrians after dark.
