RESUMO
OBJECTIVE: The present study aims to: 1) determine whether the risks associated with distracted walking are influenced by walking environment by estimating the incidence and severity of phone-related distracted walking injuries; and 2) investigate individuals' perceptions of distracted walking risk within different walking environments to understand whether individuals are aware of the potential risks and the manner in which they understand those risks. BACKGROUND: Distracted walking has been increasingly considered a public safety issue over the past few years. Research has focused on understanding the many factors that may influence pedestrians' engagement with smart-devices in order to address this issue. Risk perception may be one factor that guides engagement decisions but has not been widely studied in the context of distracted walking. Risk perception and the consequences of distracted walking are likely to be impacted by the walking environment, however, current research has typically focused on a subset of locations- streets and intersections. METHOD: This study used the National Electronic Injury Surveillance System (NEISS), a national database of injuries due to consumer products, to understand the number and severity of distracted walking injuries and locations where it occurred. Phone related injury cases from 2011 to 2019 were extracted and categorized by two independent raters in terms of cause of injury and location of injury. An online questionnaire, N = 207, was used to understand how individuals' perception of risk in five different walking environments (intersections, stairwells, hallways, pedestrian plazas, and parking lots) were related to distraction engagement. Risk perception was measured through three different framings: risk of distracted walking (i.e., overall risk of engaging with the behavior), risk of collision and risk of falls (e.g., risks associated with the consequences of engaging with the behavior). RESULTS: The NEISS analysis showed an upward trend of distracted walking injuries from 2011 (2184 incidents) to 2019 (4711 incidents) and that the number of injuries differed across the different walking environments. The survey results showed that individuals varied their risk perception levels (risk of distracted walking, collision, and falls) based on the walking environment and distraction status (distraction and no distraction). The relationship between overall risk of distracted walking and the risks of the different consequences (falls & collision) differed by walking environment. Finally, significant negative correlations were found between risk perception and actual distraction engagement for each location.
