By using a correspondence analysis the authors related the characteristics of the roads in a target area with the feelings of the elderly concerning snatch occurrences on these roads. The target area was divided into 10 groups, by using the k-means clustering method. The results can be summarized as follows: (1) Group 2 presents the highest rate of snatch occurrence (45.2%) and a feeling of security, implying that individuals feel an unreasonable sense of security on unsafe roads. The roads in this group have the largest percentage of shops (45.6%), longest roads, largest sidewalks, and the lowest ratio of length of open spaces/parking lots to the road length. (2) Groups 4 and 5 present low rates of snatch occurrence (12.5%, 8.3%), implying that individuals harbor an unreasonable sense of insecurity concerning safe roads. The roads in these groups have the largest percentage of houses (65.5%, 62.5%), shorter roads (34.9 m, 49.9 m) than the average, not many sidewalks, and the highest ratio of length of open spaces/parking lots to the road length. Based on these results, the authors clarified the characteristics of the roads in a target area, clustered based on the reasons why people feel secure/insecure about snatch occurrences on roads.
