Corresponding Characteristics and Circumstances of Collision-Involved Pedestrians in Hawaii

Correspondence analysis is used to explore the relationships between the characteristics and circumstances of collision-involved pedestrians in Hawaii. The purpose of this study is twofold. First, it is to apply and understand how best to use a powerful exploratory data technique (correspondence analysis) for safety research. The second purpose is to understand better the nature and causes of pedestrian accidents. The circumstances associated with pedestrian fault, serious injury, and the effects of location and temporal factors are examined. Correspondence analysis is a technique that allows one to examine the relationships between various discrete or categorical variables and to consider the effects of gender, age groupings, time, and location on pedestrian fault and injury. The technique is useful not only in clarifying the important relationships but also in designing appropriate strategies and interventions for the reduction of pedestrian accidents. The analysis suggests that greater emphasis be directed toward drivers, who are 13.8 times more likely to be classified as being at fault than the pedestrian they collide with. It is also evident that there are differences between seniors and other pedestrians in terms of injuries sustained. Moreover, specified programs might be targeted to men, children, and young adults.
